Abstract
Plant induced responses to environmental stressors are increasingly studied in a behavioral ecology context. This is particularly true for plant induced responses to herbivory that mediate direct and indirect defenses, and tolerance. These seemingly adaptive alterations of plant defense phenotypes in the context of other environmental conditions have led to the discussion of such responses as intelligent behavior. Here we consider the concept of plant intelligence and some of its predictions for chemical information transfer in plant interaction with other organisms. Within this framework, the flow, perception, integration, and storage of environmental information are considered tunable dials that allow plants to respond adaptively to attacking herbivores while integrating past experiences and environmental cues that are predictive of future conditions. The predictive value of environmental information and the costs of acting on false information are important drivers of the evolution of plant responses to herbivory. We identify integrative priming of defense responses as a mechanism that allows plants to mitigate potential costs associated with acting on false information. The priming mechanisms provide short- and long-term memory that facilitates the integration of environmental cues without imposing significant costs. Finally, we discuss the ecological and evolutionary prediction of the plant intelligence hypothesis.

Abstract
PURPOSE The aim of the present review is to analyze dynamic interactions between nutrigenomics, environmental cues, and parental influence, which can all lead to children's neophobic reactions and its persistence in time. METHODS We reviewed studies available on electronic databases, conducted on children aged from birth to 18 years. We also considered official websites of Italian Institutions, providing advice on healthy eating during infancy. RESULTS Modern day societies are faced with an eating paradox, which has severe and ever-growing implications for health. In face of a wider availability of healthy foods, individuals instead often choose processed foods high in fat, salt and sugar content. Economic reasons surely influence consumers' access to foods. However, there is mounting evidence that food choices depend on the interplay between social learning and genetic predispositions (e.g., individual eating traits and food schemata). Neophobia, the behavioral avoidance of new foods, represents an interesting trait, which can significantly influence children's food refusal. Early sensory experiences and negative cognitive schemata, in the context of primary caregiver-child interactions, importantly contribute to the priming of children's food rejection. CONCLUSIONS As neophobia strongly affects consumption of healthy foods, it will be relevant to rule definitively out its role in the genesis of maladaptive food choices and weight status in longitudinal studies tracking to adulthood and, in meanwhile, implement early in life effective social learning strategies, to reduce long-term effects of neophobia on dietary patterns and weight status. LEVEL OF EVIDENCE Level II, controlled trials without randomization.

Abstract
Humans can accurately estimate and track object motion, even if it accelerates. Research shows that humans exhibit superior estimation and tracking performance for descending (falling) than ascending (rising) objects. Previous studies presented ascending and descending targets along the gravitational and body axes in an upright posture. Thus, it is unclear whether humans rely on congruent information between the direction of the target motion and gravity or the direction of the target motion and longitudinal body axes. Two experiments were conducted to explore these possibilities. In Experiment 1, participants estimated the arrival time at a goal for both upward and downward motion of targets along the longitudinal body axis in the upright (both axes of target motion and gravity congruent) and supine (both axes incongruent) postures. In Experiment 2, smooth pursuit eye movements were assessed while tracking both targets in the same postures. Arrival time estimation and smooth pursuit eye movement performance were consistently more accurate for downward target motion than for upward motion, irrespective of posture. These findings suggest that the visual experience of seeing an object moving along an observer's leg side in everyday life may influence the ability to accurately estimate and track the descending object's motion.

Abstract
Recently, approach-avoidance tendencies and visual perception biases have been increasingly studied using bistable point-light walkers (PLWs). Prior studies have found a facing-the-viewer bias when one is primed with general threat stimuli (e.g. angry faces), explained by the "error management theory", as failing to detect a threat as approaching is riskier than the opposite. Importantly, no study has explored how disease threat - linked to the behavioural immune system - might affect this bias. This study aimed to explore whether disease-signalling cues can alter how we perceive the motion direction of ambiguous PLWs. Throughout 3 experiments, participants indicated the motion direction of a bistable PLW previously primed with a control or disease-signalling stimuli - that is, face with a surgical mask (Experiment 1), sickness sound (Experiment 2), or face with a disease cue (Experiment 3). Results showed that sickness cues do not significantly modulate the perception of approach-avoidance behaviours. However, a pattern emerged in Experiments 2 and 3, suggesting that sickness stimuli led to more facing away percepts. Unlike other types of threat, this implies that disease-related threat stimuli might trigger a distinct perceptual bias, indicating a preference to avoid a possible infection source. Nonetheless, this finding warrants future investigations.

Abstract
Research on perceptions of sexual interest has documented the tendency for men to overperceive sexual interest (i.e., to perceive a social signal as indicating more sexual intent than the actor intended). However, this work has almost exclusively focused upon these dynamics among heterosexual individuals. Thus, the current set of studies aimed to understand how perceptions of sexual interest manifest among lesbian, gay, and bisexual (LGB) women and men. In Study 1 (N = 85), LGB women and men nominated behaviors that signal sexual intent. Using an act nomination approach, LGB women and men tended to nominate behaviors similar to those nominated by heterosexual women and men. In Study 2 (N = 43), gay men reported acts that were representative of their own and other gay men's sexual interest. Consistent with previous work-by comparing perceived self-reported versus others' sexual intent when engaging in specific behaviors-we found no evidence for a sexual overperception bias in gay men, albeit in a small field study. In Study 3 (N = 307), using a gender-by-sexual orientation design, heterosexual and LGB women and men reported previous experiences in which their friendliness was sexually misperceived. Bisexual women were less likely than other groups to report their friendliness being misinterpreted as sexual by other bisexual women and/or lesbians. Additionally, across all genders and sexual orientations, participants reported feelings of indifference, awkwardness and embarrassment when being misperceived. Ultimately, the current studies' results provide broader insight into the nature of sexual overperception among LGB populations.

Abstract
Body experiences and conditions bear close relations to social development and human well-being. However, no consensus has been reached regarding the impact of coronavirus disease 2019 on negative body image. Investigating a reliable relationship between COVID-19 and negative body image, we developed a dictionary of negative body image to obtain panel data on body image for 31 Chinese provinces/municipalities/autonomous regions. We compared negative body image before and after the pandemic and explored the impact of pandemic severity. The prevalence of negative body image decreased following the outbreak and remained at a relatively low level for two years. After controlling regional and temporal effects, we verified epidemic severity as an important predictor of the decline in negative body image. The findings suggest that the public is likely to accept their physical appearances during lockdown due to changes in lifestyle and the fear of mortality. This research has important implications for gaining insights into the dynamic transformation of public negative body image under the influence of catastrophic public health events.

Abstract
Background and objectives The behavioural immune system (BIS) is a motivational system that facilitates the avoidance of pathogens and is thought to have evolved as a less costly mechanism to combat infectious diseases compared to the physiological immune system. The Parasite Stress Theory of Social Values predicts that authoritarianism and collectivist attitudes may impact the BIS by predisposing people to support disease control measures, including severe restrictions like lockdowns or stay-at-home orders. This study investigates the relationship between authoritarianism, collectivism and Covid-19 worry on support for lockdown measures during the Covid-19 pandemic. Methodology A total of 187 UK participants were recruited to complete an online survey, which was administered between 22 June and 7 July 2020. The survey included measures of authoritarianism, collectivism, Covid-19 worry and support for lockdown measures. The data were analysed using moderated parallel mediation analysis. Results Covid-19 worry had a direct effect on support for and enforcement of lockdown measures, but not on the idea that adherence to lockdown rules should be an individual choice. The relationship between Covid Worry and Support for and Enforcement of lockdown measures was not mediated by authoritarianism, nor was it moderated by Collectivism. Collectivism and Authoritarianism were related to increased levels of support for lockdown independently from Covid Worry but were not related to enforcement. Conclusions and implications Support for lockdown restrictions and enforcement was mainly associated with covid worry. Our findings do not support the parasite stress theory of social values and indicate that the BIS manifested in a more direct way, and not through social values.

Varella MAC. Nocturnal selective pressures on the evolution of human musicality as a missing piece of the adaptationist puzzle. Front Psychol 2023; 14:1215481.

Abstract
Human musicality exhibits the necessary hallmarks for biological adaptations. Evolutionary explanations focus on recurrent adaptive problems that human musicality possibly solved in ancestral environments, such as mate selection and competition, social bonding/cohesion and social grooming, perceptual and motor skill development, conflict reduction, safe time-passing, transgenerational communication, mood regulation and synchronization, and credible signaling of coalition and territorial/predator defense. Although not mutually exclusive, these different hypotheses are still not conceptually integrated nor clearly derived from independent principles. I propose The Nocturnal Evolution of Human Musicality and Performativity Theory in which the night-time is the missing piece of the adaptationist puzzle of human musicality and performing arts. The expansion of nocturnal activities throughout human evolution, which is tied to tree-to-ground sleep transition and habitual use of fire, might help (i) explain the evolution of musicality from independent principles, (ii) explain various seemingly unrelated music features and functions, and (iii) integrate many ancestral adaptive values proposed. The expansion into the nocturnal niche posed recurrent ancestral adaptive challenges/opportunities: lack of luminosity, regrouping to cook before sleep, imminent dangerousness, low temperatures, peak tiredness, and concealment of identity. These crucial night-time features might have selected evening-oriented individuals who were prone to acoustic communication, more alert and imaginative, gregarious, risk-taking and novelty-seeking, prone to anxiety modulation, hedonistic, promiscuous, and disinhibited. Those night-time selected dispositions may have converged and enhanced protomusicality into human musicality by facilitating it to assume many survival- and reproduction-enhancing roles (social cohesion and coordination, signaling of coalitions, territorial defense, antipredatorial defense, knowledge transference, safe passage of time, children lullabies, and sexual selection) that are correspondent to the co-occurring night-time adaptive challenges/opportunities. The nocturnal dynamic may help explain musical features (sound, loudness, repetitiveness, call and response, song, elaboration/virtuosity, and duetting/chorusing). Across vertebrates, acoustic communication mostly occurs in nocturnal species. The eveningness chronotype is common among musicians and composers. Adolescents, who are the most evening-oriented humans, enjoy more music. Contemporary tribal nocturnal activities around the campfire involve eating, singing/dancing, storytelling, and rituals. I discuss the nocturnal integration of musicality's many roles and conclude that musicality is probably a multifunctional mental adaptation that evolved along with the night-time adaptive landscape.

Abstract
Moral dilemmas are inescapable in daily life, and people must often choose between two desirable character traits, like being a diligent employee or being a devoted parent. These moral dilemmas arise because people hold competing moral values that sometimes conflict. Furthermore, people differ in which values they prioritize, so we do not always approve of how others resolve moral dilemmas. How are we to think of people who sacrifice one of our most cherished moral values for a value that we consider less important? The "Good True Self Hypothesis" predicts that we will reliably project our most strongly held moral values onto others, even after these people lapse. In other words, people who highly value generosity should consistently expect others to be generous, even after they act frugally in a particular instance. However, reasoning from an error-management perspective instead suggests the "Moral Stringency Hypothesis," which predicts that we should be especially prone to discredit the moral character of people who deviate from our most deeply cherished moral ideals, given the potential costs of affiliating with people who do not reliably adhere to our core moral values. In other words, people who most highly value generosity should be quickest to stop considering others to be generous if they act frugally in a particular instance. Across two studies conducted on Prolific (N = 966), we found consistent evidence that people weight moral lapses more heavily when rating others' membership in highly cherished moral categories, supporting the Moral Stringency Hypothesis. In Study 2, we examined a possible mechanism underlying this phenomenon. Although perceptions of hypocrisy played a role in moral updating, personal moral values and subsequent judgments of a person's potential as a good cooperative partner provided the clearest explanation for changes in moral character attributions. Overall, the robust tendency toward moral stringency carries significant practical and theoretical implications.

Abstract
Partners' behaviors outside the bedroom may spill over into the bedroom. One such behavior is responsiveness, as it creates a relationship ambiance conducive to the development of intimacy. In this article, I review research demonstrating how perceiving partners as responsive outside the bedroom affects the quality of sexual interactions, highlighting changes in the contextual meaning of partner responsiveness across individuals and relationship stages. I then provide an overview of the costs and benefits of responsiveness within the bedroom. I conclude by suggesting directions for future research on the potential of partner responsiveness for fostering a relationship environment that inoculates against alternative partners as well as for designing social robots and virtual mates for those in need of a surrogate partner.

Abstract
Ostensibly serving to restrict contact with disease vectors, humans exhibit aversion toward cues heuristically inferred as pathogenic. This restriction could lead perceivers to downregulate their interest in food consumption, even if such cues may not connote actual disease threats. This proclivity to avoid disease led us to consider how heuristic disease cues inform interest in foods. Participants evaluated a hypothetical food preparer that varied in the presence of heuristic cues to disease transmission (i.e., physical deformities versus healthy control). Individuals with low levels of perceived infectability were more discerning of the social target as a function of disease cues, whereas heightened levels of this trait fostered an overall aversion to targets regardless of health status. Results provide continued evidence for how pathogen avoidance motives compete with other somatic motives.

Abstract
Neuropronostication for consciousness disorders can be very complex and prone to high uncertainty. Despite notable advancements in the development of dedicated scales and physiological markers using innovative paradigms, these technical progressions are often overshadowed by factors intrinsic to the medical environment. Beyond the scarcity of objective data guiding medical decisions, factors like time pressure, fatigue, multitasking, and emotional load can drive clinicians to rely more on heuristic-based clinical reasoning. Such an approach, albeit beneficial under certain circumstances, may lead to systematic error judgments and impair medical decisions, especially in complex and uncertain environments. After a brief review of the main theoretical frameworks, this paper explores the influence of clinicians' cognitive biases on clinical reasoning and decision-making in the challenging context of neuroprognostication for consciousness disorders. The discussion further revolves around developing and implementing various strategies designed to mitigate these biases and their impact, aiming to enhance the quality of care and the patient safety.

Abstract
Immigration has become a focal debate in politics across the world. Recent research suggests that anti-immigration attitudes may have deep psychological roots in implicit disease avoidance motivations. A key implication of this theory is that individual differences in disease avoidance should be related to opposition to immigration across a wide variety of cultural and political contexts. However, existing evidence on the topic has come almost entirely from the United States and Canada. In this article, we test the disease avoidance hypothesis using nationally representative samples from Norway, Sweden, Turkey, and Mexico, as well as two diverse samples from the United States. We find consistent and robust evidence that disgust sensitivity is associated with anti-immigration attitudes and that the relationship is similar in magnitude to education. Overall, our findings support the disease avoidance hypothesis and provide new insights into the nature of anti-immigration attitudes.

Abstract
Automatic action tendencies occur at behavioral and neurophysiological levels during task performance with the dominant right hand, with shorter reaction times (RTs) and higher excitability of the contralateral primary motor cortex (M1) during automatic vs. regulated behavior. However, effects associated with the non-dominant left-hand in approaching-avoiding behavior remain unclear. Here, we used transcranial magnetic stimulation during the performance by 18 participants of an approaching-avoiding task using the non-dominant left hand. Single-pulse transcranial magnetic stimulation was applied over left or right M1 at 150 and 300 ms after the onset of an emotional stimulus. RTs and motor-evoked potentials (MEPs) were recorded. Significant automatic action tendencies were observed at the behavioral level. Higher MEP amplitudes were detected 150 ms after stimulus onset from the right hand (non-task hand, corresponding to left M1) during regulated behavior compared with during automatic behavior. However, no significant modulation was found for MEP amplitudes from the left hand (task hand, corresponding to right M1). These findings suggested that left M1 may play a principal role in the early phase of mediating left-handed movement toward an emotional stimulus.

Abstract
The rapid advances of science and technology have provided a large part of the world with all conceivable needs and comfort. However, this welfare comes with serious threats to the planet and many of its inhabitants. An enormous amount of scientific evidence points at global warming, mass destruction of bio-diversity, scarce resources, health risks, and pollution all over the world. These facts are generally acknowledged nowadays, not only by scientists, but also by the majority of politicians and citizens. Nevertheless, this understanding has caused insufficient changes in our decision making and behavior to preserve our natural resources and to prevent upcoming (natural) disasters. In the present study, we try to explain how systematic tendencies or distortions in human judgment and decision-making, known as “cognitive biases,” contribute to this situation. A large body of literature shows how cognitive biases affect the outcome of our deliberations. In natural and primordial situations, they may lead to quick, practical, and satisfying decisions, but these decisions may be poor and risky in a broad range of modern, complex, and long-term challenges, like climate change or pandemic prevention. We first briefly present the social-psychological characteristics that are inherent to (or typical for) most sustainability issues. These are: experiential vagueness, long-term effects, complexity and uncertainty, threat of the status quo, threat of social status, personal vs. community interest, and group pressure. For each of these characteristics, we describe how this relates to cognitive biases, from a neuro-evolutionary point of view, and how these evolved biases may affect sustainable choices or behaviors of people. Finally, based on this knowledge, we describe influence techniques (interventions, nudges, incentives) to mitigate or capitalize on these biases in order to foster more sustainable choices and behaviors.

Abstract
Because Black and Arab men may be stereotyped as hostile in different ways (i.e., physical vs. ideological), this study assessed whether an old age identity versus gay identity would reduce stereotypes related to hostility for Black and Arab men differently. We assessed whether the addition of an old age identity reduces hostile stereotype content more for Black men than for Arab men. In line with our hypothesis, an old age identity resulted in participants reporting fewer hostile stereotypes for Black men, but not for Arab men. We also assessed whether a gay identity reduces hostile stereotype content in the same way for Black and Arab men. As expected, a gay identity resulted in participants reporting fewer hostile stereotypes for both male groups. The present study demonstrates the importance of considering intersecting identities in person perception and highlights the unique challenges faced by men belonging to these intersecting groups.

Abstract
Personality disorders (PDs) are currently considered dysfunctions. However, personality differences are older than humanity and are ubiquitous in nature, from insects to higher primates. This suggests that a number of evolutionary mechanisms-other than dysfunctions-may be able to maintain stable behavioral variation in the gene pool. First of all, apparently maladaptive traits may actually improve fitness by enabling better survival or successful mating or reproduction, as exemplified by neuroticism, psychopathy, and narcissism. Furthermore, some PDs may harm important biological goals while facilitating others, or may be globally beneficial or detrimental depending on environmental circumstances or body condition. Alternatively, certain traits may form part of life history strategies: Coordinated suites of morphological, physiological and behavioral characters that optimize fitness through alternative routes and respond to selection as a whole. Still others may be vestigial adaptations that are no longer beneficial in present times. Finally, variation may be adaptative in and by itself, as it reduces competition for finite resources. These and other evolutionary mechanisms are reviewed and illustrated through human and non-human examples. Evolutionary theory is the best-substantiated explanatory framework across the life sciences, and may shed light on the question of why harmful personalities exist at all.

Abstract
Much research suggests mental health diagnoses elicit stigmatization of individuals. The current study builds upon this literature at the intersection of same- and cross-race perceptions. Black and White participants viewed Black and White targets paired with either a mental health diagnosis (e.g., depression), a physical health diagnosis (e.g., high blood pressure), or no health information (control) while indicating each target's favorability and how much social distance they would want from them. Overall, people were more stigmatizing toward targets with a mental health diagnosis than a physical health diagnosis or no diagnosis. Black targets with a mental health diagnosis were stigmatized more than White targets with a mental health diagnosis and White participants displayed a greater aversion to Black targets with a mental health diagnosis than did Black participants. Results contribute to the mental health stigma literature and suggest it may be particularly problematic for White perceivers' attitudes toward Black individuals with mental health diagnoses. Findings may shed light on the racial differences in treatment-seeking amongst Black and White individuals.

Abstract
BACKGROUND Although some jurisdictions have implemented particular adjustments to accommodate often-expensive orphan drugs in their healthcare systems, availability of these drugs remains complex. This study investigates alternative financing models and early access schemes for orphan drugs in the context of the Belgian healthcare system. METHODS Three focus group discussions were held with a panel of eleven experts from the Belgian Drug Reimbursement Committee, the Colleges for Orphan Drugs, the pharmaceutical industry, physicians, ethicists and pharmacists. Retrieved data were pseudonymised, analysed and coded according to the Qualitative Analysis Guide of Leuven. RESULTS Experts disfavoured the insulated fund as well as private insurance for financing orphan drugs, as, respectively, isolation of a separate budget and a mostly profit-driven mechanism would contradict the Belgian fundamental principle of solidarity. Moreover, an insulated fund could, albeit on a smaller scale, reproduce the same budgetary constraints as the general reimbursement system. As the Special Solidarity Fund is intended for urgent care and exclusively accommodates financial needs subject to eligibility criteria, its design would not allow general financing of orphan drugs. Overall, implementation of an alternative financing model was not endorsed, instead, improving the current reimbursement system was preferred. Suggestions mentioned were; increased collaboration and transparency, robust and quality real-world evidence but also digitalization of data. Alleviating administrative burden and simplifying the admission process of compassionate use program, medical need program and early treatment reimbursement should be prioritized to facilitate early access. Furthermore, a legal framework for off-label use could stimulate proper implementation. Efforts on collaboration of expertise centres and coordination of orphan drug databases across Europe could foster a robust data network to support orphan drug availability in individual countries. CONCLUSIONS This research reveals that reassessing current financing models and early access schemes by eliminating inadequacies, may be more conducive than establishing alternative systems to increase availability of orphan drugs in Belgium. Other jurisdictions may rely on this information to review their own models of early access and financing to cultivate a more sustainable delivery of orphan drugs.

Abstract
Affective states are of increasing interest in the assessment of animal welfare. This research aimed to evaluate the possible limitations in the application of a spatial judgment bias test (JBT) in horses, considering the influence of stress level, personality traits, and the possible bias due to the test structure itself. The distinction between two positions, one rewarded (Positive) and the other not (Negative), was learned by 10 horses and 4 ponies,. Then, the latency to reach three unrewarded ambiguous positions (Near Positive, Middle, Near Negative) was measured. Furthermore, the validated Equine Behavior Assessment and Research Questionnaire (E-BARQ) was employed to assess personality traits. Fecal and hair cortisol levels were measured through radioimmunoassay (RIA), and the frequency of behavioral stress indicators was recorded. Results showed that horses that had the rewarded position (Positive) on the right approached Near Negative and Middle faster than those that had Positive on the left. Certain personality traits influenced the latency to reach Middle and Near Positive, but chronic stress did not seem to affect horses' judgment bias. This preliminary study highlighted several limitations in the employment of spatial JBT for the assessment of affective state in horses and that personality traits can partially influence the cognitive process. Further research is needed to refine the use of this test in horses, considering the peculiarities both of species and of individuals.

Abstract
Paranoia and conspiracy are terms typically used interchangeably. However, although the underlying content of these types of beliefs might be similar (e.g., seeing others as powerful and threatening), recent research suggests that these constructs differ in important ways. One important feature shared by both constructs is excessive mistrust but this aspect might play different roles in each belief system. In this study we explored the strength of associations of different trust predictors (i.e., trust in institutions, trust in sources of information, perceptual trust, and interpersonal trust) between conspiracy mentality and paranoid beliefs. We tested this association in a large representative multinational sample (United Kingdom n = 2025; Spain n = 1951; and Ireland n = 1041). Confirmatory factor analysis supported a two-factor model of conspiracy and paranoid beliefs in each nation sample. Path and equality of constraints analysis revealed that paranoia was more strongly associated with perceptual mistrust (bias towards mistrusting unfamiliar faces) whereas conspiracy was more strongly associated with mistrust in political institutions. Although interpersonal mistrust and trust in social sources of information were associated significantly with conspiracy their association with paranoid beliefs was stronger. These findings clarify the role of different trust processes in both belief systems. Limitations of this study are discussed.

Abstract
Automatic preferences can influence a decision maker's choice before any relevant or meaningful information is available. We account for this element of human cognition in a computational model of problem solving that involves active trial and error and show that automatic biases are not just a beneficial or detrimental property: they are a tool that, if properly managed over time, can give rise to superior performance. In particular, automatic preferences are beneficial early on and detrimental at later stages. What is more, additional value can be generated by a timely rebiasing, i.e., a calculated reversal of the initial automatic preference. Remarkably, rebiasing can dominate not only debiasing (i.e., eliminating the bias) but also continuously unbiased decision making. This research contributes to the debate on the adaptiveness of automatic and intuitive biases, which has centered primarily on one-shot controlled laboratory experiments, by simulating outcomes across extended time spans. We also illustrate the value of the novel intervention of adopting the opposite automatic preference-something organizations can readily achieve by changing key decision makers-as opposed to attempting to correct for or simply accepting the ubiquity of such biases.

Social pain by non-social agents: Exclusion hurts and provokes punishment even if the excluding source is a computer. Acta Psychol (Amst) 2022; 230:103753.

Abstract
Prior research has shown that being excluded by computer-agents in experimental exclusion paradigms threatens individuals' basic needs to a similar extent as being excluded by humans. It is less clear, however, why this similarity between computer and human exclusion occurs, and whether it applies only to reactions immediately after the exclusion event (reflexive stage), or also to reactions that occur further downstream (e.g., reflective stage). Four studies (N = 1048) with three different exclusion paradigms provide several key insights: First, the similarity between computer and human exclusion is robust and pervasive, as Bayesian analyses provide consistent support that the source of exclusion (human vs. computer) does not affect reflexive need satisfaction. Second, this similarity also extends to reflective reactions and punishing behavior. Finally, the present studies extend our knowledge about the processes underlying this similarity by uncovering the role of anthropomorphism. Implications and directions for future research are discussed.

Abstract
Mental budgeting is a cognitive process that helps individuals control consumption expenditures. Previous literature has shown that mental budgeting is influenced by people's cognitive capabilities and emotions, which indicates a potential influence of thinking modes on mental budgeting. Under the view of lay rationalism, the present three studies investigated the relationship between thinking modes (i.e., calculation-based thinking and feeling-based thinking) and mental budgeting, as well as the moderating effect of product types that participants consume. It was found that, first, the scores of lay rationalism, which indicate calculation-based thinking, were positively correlated with the mental budgeting levels of college students (Study 1a) and newcomers in the workplace (Study 1b); second, the activation of calculation-based thinking (vs. feeling-based thinking) decreased participants' consumption willingness (Study 2); and third, the calculation-based thinking exhibited a stronger binding effect in participants who consumed only hedonic products than in participants who consumed only utilitarian products (Study 2). The results demonstrated the effects of lay rationalism thinking mode and product types on mental budgeting, which highlighted different implications for consumers and merchants.

Abstract
Although extensive research has been conducted on promoting pro-environmental behaviors among consumers, little is known about whether and how negative anthropomorphic message framing (NAMF) and nostalgia affect pro-environmental behavior. To provide a framework for explaining pro-environmental behavior, this study integrates protection motivation theory, the stimulus-organism-response model, and message framing. To create the model of the influences on pro-environmental behavior, NAMF was employed as the external stimulus; the sense of environmental responsibility, environmental empathy, perceived threat, and perceived vulnerability as the psychological and cognitive response factors; pro-environmental behavior as the final decision of consumers; and nostalgia as the moderating variable. An online questionnaire was distributed and 380 usable questionnaires were collected using convenience sampling and analyzed using two complementary approaches: partial least squares structural equation modeling (PLS-SEM) and necessary condition analysis (NCA). PLS-SEM results showed that pro-environmental behavior was significantly affected by NAMF (β = 0.313, t-value = 5.583), environmental responsibility (β = 0.207, t-value = 3.994), and perceived threats (β = 0.252, t-value = 4.889). Meanwhile, an increase in nostalgia increased the effect of NAMF and environmental responsibility on pro-environmental behavior. The NCA results revealed that NAMF (d = 0.108, p < 0.001) and perceived threat (d = 0.209, p < 0.001) were key factors of pro-environmental behavior. In addition, for high level of pro-environmental behavior (>80%), NAMF (12.1%) and perceived threat (39.6%) are required. Finally, we offer several suggestions based on the results of our empirical research. For example, marketing and service offerings should be tailored to the needs of masses with different nostalgic tendencies to enhance their pro-environmental behaviors.

Abstract
Non-verbal cues tone our communication. Previous studies found that non-verbal factors, such as spatial distance and gaze direction, significantly impact interpersonal communication. However, little is known about the behind multi-brain neural correlates and whether it could affect high-level creative group communication. Here, we provided a new, scalable, and neuro-based approach to explore the effects of non-verbal factors on different communication tasks, and revealed the underlying multi-brain neural correlates using fNIRS-based hyperscanning technique. Across two experiments, we found that closer spatial distance and more direct gaze angle could promote collaborative behaviors, improve both creative and non-creative communication outcomes, and enhance inter-brain neural synchronization. Moreover, compared to the non-creative communication task, participants' inter-brain network was more intertwined when performing the creative communication task. These findings suggest that close spatial distance and direct gaze serve as positive social cues, bringing interacting brains into alignment and optimizing inter-brain information transfer, thus improving communication outcomes.

Abstract
This article explores an often-untouched subject in anesthesiology residency: relationships. The authors examine the importance of fostering all types of relationships (eg, personal, professional, self) and the impact of the training process on relationships and total well-being. Common issues in relationships during anesthesiology residency are shared through real-life anecdotes from physicians who are currently in or have completed their residencies. Psychological principles including optimism bias, cognitive dissonance, social comparison, and self-efficacy are explored as contributing to dysfunction in relationships. Strategies are offered for each psychological domain as a resource for faculty and program leadership to improve the residency experience in anesthesiology.

Abstract
People have an "anomalous-is-bad" stereotype whereby they make negative inferences about the moral character of people with craniofacial anomalies like scars. This stereotype is hypothesized to be a byproduct of adaptations for avoiding pathogens. However, evidence for the anomalous-is-bad stereotype comes from studies of European and North American populations; the byproduct hypothesis would predict universality of the stereotype. We presented 123 Hadza across ten camps pairs of morphed Hadza faces-each with one face altered to include a scar-and asked who they expected to be more moral and a better forager. Hadza with minimal exposure to other cultures chose at chance for both questions. Hadza with greater exposure to other cultures, however, expected the scarred face to be less moral and a better forager. These results suggest the anomalous-is-bad stereotype may be culturally shared or learned erroneously through associations with population-level differences, providing evidence against a universal pathogen avoidance byproduct hypothesis.

Abstract
The meaning of places is socially constructed, often informed by the groups that seem pervasive there. For instance, the University of Pennsylvania is sometimes called "Jew-niversity of Pennsylvania," and the city of Decatur, Georgia, is disparagingly nicknamed "Dyke-atur," connoting the respective pervasiveness of Jewish students and gay residents. Because these pervasiveness perceptions meaningfully impact how people navigate the social world, it is critical to understand the factors that influence their formation. Across surveys, experiments, and archival data, six studies (N = 3,039 American adults) revealed the role of symbolic threat (i.e., perceived differences in values and worldviews). Specifically, holding constant important features of the group and context, we demonstrated that groups higher in symbolic threat are perceived as more populous in a place and more associated with that place than groups lower in symbolic threat. Ultimately, this work reveals that symbolic threat can both distort how people understand their surroundings and shape the meaning of places.

Abstract
This study aimed to examine differences between men and women and between Muslims, secular Jews, and religious Jews in their motivations for using sanctions within their intimate relationships. This work involved heterosexual couples from the general population. The sample included 95 Muslim, 68 secular Jewish, and 70 ultra-orthodox Jewish couples (466 participants). The findings of the study show that sanction use during times of conflict is prevalent among the vast majority of couples. Motivations for the use of sanctions are stronger among women than men. In addition, the strongest motivation expressed by both genders was a motivation for conflict resolution. This is the first time that sanctions, as a tactic to cope with conflict, have been addressed in a scholarly manner. This study provides a preliminary estimate of how commonly these types of behaviors are used in intimate relationships. Theoretical and empirical implications of the theoretical framework and the findings are discussed, including the role of the use of sanction in the escalation of intimate partner conflicts.

Abstract
Slowing the spread of COVID-19 requires people to actively change their lives by following protective practices, such as physical distancing and disinfecting their hands. Perceptions about the personal risk of COVID-19 may affect compliance with these practices. In this study, we assessed risk perception and optimism about COVID-19 in a multinational (UK, USA and Germany), longitudinal design during the early stages of the pandemic (16 March 2020; 1 April 2020; 20 May 2020). Our main findings are that (i) people showed a comparative optimism bias about getting infected and infecting others, but not for getting severe symptoms, (ii) this optimism bias did not change over time, (iii) optimism bias seemed to relate to perceived level of control over the action, (iv) risk perception was linked to publicly available information about the disorder, (v) people reported adhering closely to protective measures but these measures did not seem to be related to risk perception, and (vi) risk perception was related to questions about stress and anxiety. In additional cross-sectional samples, we replicated our most important findings. Our open and partly preregistered results provide detailed descriptions of risk perceptions and optimistic beliefs during the early stages of the COVID-19 pandemic in three Western countries.

Abstract
Unrealistic optimism is the tendency to perceive oneself as safer than others in situations that equally threaten everybody. By reducing fear, this bias boosts one's well-being; however, it is also a deterrent to one's health. Three experiments were run in a mixed-design on 1831 participants to eliminate unrealistic optimism (measured by two items-probability of COVID-19 infection for oneself and for others; within-subjects) toward the probability of COVID-19 infection via articles/videos. A between-subject factor was created by manipulation. Ostensibly, daily newspaper articles describing other people diligently following medical recommendations (experiment 1) and videos showing people who did not follow these recommendations (experiment 2) reduced unrealistic optimism. The third experiment, which included both articles and videos, replicated these results. These results can be applied to strategies for written and video communications that can be used by governments and public health agencies as best practices concerning not only COVID-19 but also any subsequent public health threat while promoting proactive, optimal, and healthy functioning of the individual.

Abstract
Determining the valence of an odor to guide rapid approach-avoidance behavior is thought to be one of the core tasks of the olfactory system, and yet little is known of the initial neural mechanisms supporting this process or of its subsequent behavioral manifestation in humans. In two experiments, we measured the functional processing of odor valence perception in the human olfactory bulb (OB)-the first processing stage of the olfactory system-using a noninvasive method as well as assessed the subsequent motor avoidance response. We demonstrate that odor valence perception is associated with both gamma and beta activity in the human OB. Moreover, we show that negative, but not positive, odors initiate an early beta response in the OB, a response that is linked to a preparatory neural motor response in the motor cortex. Finally, in a separate experiment, we show that negative odors trigger a full-body motor avoidance response, manifested as a rapid leaning away from the odor, within the time period predicted by the OB results. Taken together, these results demonstrate that the human OB processes odor valence in a sequential manner in both the gamma and beta frequency bands and suggest that rapid processing of unpleasant odors in the OB might underlie rapid approach-avoidance decisions.

Abstract
The aim of this study was to determine the relationship between the attitudes toward the Covid-19 vaccine and life satisfaction, religious attitude, and the avoidance attitudes from Covid-19. This cross-sectional study was conducted online between 24 December 2020 and 06 January 2021 among adults age 18 years and older. Total 1033 people participated in the study. The data were collected using the Attitudes Toward Covid-19 Vaccine, Avoiding Attitudes from COVID-19, Religious Attitude Scale and Contentment with Life Assessment Scale. According to the "agree" and "strongly agree" responses of participants to the positive attitude items; the participants responded to the question "Who would you like to be vaccinated?" as follows: everyone (31.3%); family members (31.8%); and themselves (28.1%). The rates of those who responded to these items as "indecisive" were 44.5-48.2%. While there was no significant relationship between the COVID-19 vaccine attitude with the avoidance attitude from COVID-19 and the religious attitude; life satisfaction was found to be significant. It was observed that factors such as increasing fear of COVID-19 contagion, being male, increased life satisfaction, other relatives infected with Covid-19, increasing perceived health status, increased age, and not being a worker-tradesman increase the probability of having a positive attitude toward COVID-19 vaccine. It was observed that about one-third of the participants think the COVID-19 vaccine is protective and supports its administration, that almost half of them were undecided on these issues. Thus, it can be said that society needs accurate information about vaccination.

Abstract
Conspiracy theories are widespread and have a profound impact on society. The present contribution proposes that conspiracy theories are explanatory narratives that necessarily contain justice judgments, as they include attributions of blame and accusations of unethical or criminal conduct. Conspiratorial narratives also are mental simulations, however, and may elicit genuine feelings of injustice also without evidence of actual malpractice. Indeed, conspiracy theories sometimes describe unfair events that are unlikely to have occurred, unethical authorities that might not actually exist, and so on. Here I propose two complementary processes that stimulate belief in evidence-free conspiracy theories: (1) Existential threats instigate biased mental processing and motivated reasoning, that jointly promote an alternative perception of reality; and (2) group allegiances shape how people perceive, interpret, and remember facts to highlight the immoral qualities of competing outgroups. Due to these processes, conspiracy theories elicit a set of distinct reactions such as poor health choices and rejection of science. Moreover, evidence-free conspiracy theories require interventions beyond traditional approaches to install justice principles, such as debunking falsehoods and reducing polarized intergroup distinctions. I conclude that the scientific study of conspiracy theories is part of, and has a unique place in, social justice research.

Abstract
Topics of prejudice, discrimination, and negative attitudes toward outgroups have attracted much attention of social scientists during the COVID-19 pandemic, as the preference for social distancing can originate from the perception of threat. One of the theoretical approaches that offers an explanation for avoidance tendencies is the behavioral immune system theory. As a motivational system that aims to identify and avoid pathogens, the behavioral immune system has been shown to be triggered by various cues of a potential disease threat (e.g., the risk of contracting a virus), which further leads to negative social consequences such as xenophobia, negative attitudes toward various social groups, and distancing tendencies. We present a correlational study (N = 588; Polish sample) that was designed to test mediational models derived from the behavioral immune system theory, using the COVID-19 pandemic as a source of natural disease threat. In serial mediation analyses we show that the perceived threat of COVID-19 translates into greater preferred social distance from foreign individuals, and that this occurs in two ways: 1) via pathogen disgust (but not sexual or moral disgust), and 2) via germ aversion (but not perceived infectability). Both pathogen disgust and germ aversion further predict general feelings toward foreign individuals, which finally determine the preferred social distance from these individuals. The results support the behavioral immune system theory as an important concept for understanding social distancing tendencies.

Abstract
OBJECTIVE Recent findings suggest crowd salience heightens pathogen-avoidant motives, serving to reduce individuals' infection risk through interpersonal contact. Such experiences may similarly facilitate the identification, and avoidance, of diseased conspecifics. The current experiment sought to replicate and extend previous crowding research. METHODS In this experiment, we primed participants at two universities with either a crowding or control experience before having them evaluate faces manipulated to appear healthy or diseased by indicating the degree to which they would want to interact with them. RESULTS Crowding-primed participants reported a more heightened preferences for healthy faces than control-primed participants. Additionally, crowd salience reduced aversion toward healthy faces but did not heighten aversion to diseased faces. CONCLUSION Results suggest crowding appears to heighten tolerance for health cues given the heightened proximal threat of infections through interpersonal contact within crowded environments. Conversely, this work extends previous findings by indicating this preference is not rooted in an aversion to cues of poor health. We frame findings from a threat management perspective in understanding how crowding fosters sensitivity toward pathogenic threats.

Abstract
OBJECTIVES Paranoia is known to be associated with insecure attachment, with negative self-esteem as a mediator, but this pathway is insufficient to explain the paranoid individual's beliefs about malevolent others. Mistrust is a likely additional factor as it is a core feature of paranoid thinking also associated with insecure attachment styles. In this study, we tested whether mistrust - operationalized as judgements about the trustworthiness of unfamiliar faces - constitutes a second pathway from insecure attachment to paranoia. DESIGN The design of the study was cross-sectional. METHODS A nationally representative British sample of 1,508 participants aged 18-86, 50.8% female, recruited through the survey company Qualtrics, completed measurements of attachment style, negative self-esteem, and paranoid beliefs. Usable data were obtained from 1,121 participants. Participants were asked to make trustworthiness judgements about computer-generated faces, and their outcomes were analysed by conducting signal detection analysis, which provided measures of bias (the tendency to assume untrustworthiness in conditions of uncertainty) and sensitivity (accuracy in distinguish between trustworthy and untrustworthy faces). RESULTS Results using structural equation modelling revealed a good model fit (RMSEA = .071, 95% CI: 0.067-0.075, SRMR = .045, CFI = .93, TLI = .92). We observed indirect effects through bias towards mistrust both for the relationship between attachment anxiety and avoidance (β = .003, 95% CI: 0.001-0.005,p < .001) and attachment anxiety and paranoia (β = .003, 95% CI 0.002-0.006, p < .001). We observed an indirect effect through negative self-esteem only for the relationship between attachment anxiety and paranoia (β = .064, 95% CI: 0.053-0.077, p < .001). Trust judgements and negative self-esteem were not associated with each other. CONCLUSIONS We find that a bias towards mistrust is associated with greater paranoia. We also find indirect effects through bias towards mistrust between attachment styles and paranoia. Finally, we reaffirm the strong indirect effect through negative self-esteem between attachment anxiety and paranoia. Limitations of the study are discussed. PRACTITIONER POINTS When working with individuals suffering from paranoia, clinicians should consider not only explicit, deliberative cognitive processes of the kind addressed in cognitive behaviour therapy (e.g. cognitive restructuring) but also the way in which their patients make perceptual judgements (e.g., their immediate reactions on encountering new people) and consider interventions targeted at these judgements, for example, bias modification training. Assessment and clinical interventions for people should consider the role of trust judgements and the way in which they combine with low self-esteem to provoke paranoid beliefs. Psychological interventions targeting paranoid beliefs should focus on both attachment anxiety and attachment avoidance.

Abstract
The present study investigated the effect of interpersonal mistreatment on the perpetrators' mental health. We proposed that the threat of COVID-19 will increase people's mental health problems through their on-line aggression toward stigmatized groups accused of spreading the disease and that there might be potential gender differences in such effects. We tested our predictions among a sample of U.S. residents (Study 1) and a large sample of Chinese residents living out of Hubei province (Study 2) during a heightened period of concern about COVID-19, February 2020. Specifically, we measured U.S. residents' on-line aggressive behaviors toward Chinese people (Study 1) and Chinese non-Hubei residents' on-line aggressive behaviors toward Hubei residents (Study 2) as well as their neuroticism (Study 1) and mental health states (Study 2). In line with our predictions, both studies showed that perceived infection of COVID-19 can induce on-line aggression toward stigmatized groups, thereby increasing people's mental health problems. Moreover, the relationship between COVID-19 vulnerability, on-line aggression, and psychosomatic symptoms was more prominent in men than in women. These results offer insights into people's responses toward COVID-19 and add to the understanding of people's mental and physical health during the epidemic stage of contagious diseases.

Abstract
Human cognition is often biased. It is a fundamental question in psychology how cognitive bias is modulated in the human brain. Automatic action tendency is a typical cognitive bias. The dorsolateral prefrontal cortex (DLPFC) is a crucial area for processing various behavioral tasks. We investigated the functional role of DLPFC in the modulation of cognitive bias by testing the automatic action tendency during automatic and regulated behavioral tasks. Unilateral intermittent or continuous theta burst stimulation (excitatory iTBS or inhibitory cTBS) was used to manipulate the left or right DLPFC excitability and assess the changes in automatic action tendency during a manikin task. An approaching behavior with positive stimulus and avoiding behavior with negative stimulus were performed in an automatic task. An approaching behavior with negative stimulus and avoiding behavior with positive stimulus were performed in a regulated task. Reaction time was measured. We confirmed the automatic action tendency that reaction time for performing an automatic task was shorter than that for performing a regulated task. The automatic action tendency was enhanced after left DLPFC excitatory iTBS and was abolished after left DLPFC inhibitory cTBS stimulation. On the other hand, right DLPFC excitatory iTBS accelerated the avoiding behaviors and right DLPFC inhibitory cTBS accelerated approaching behaviors. The results suggest that left DLPFC modulates the automatic action tendency while the right DLPFC modulates the direction of behavioral tasks. We conclude that left DLPFC and right DLPFC are key nodes in modulating the cognitive bias while their functional roles are different.

Text Analysis Methods for Misinformation–Related Research on Finnish Language Twitter. FUTURE INTERNET 2021.

Abstract
The dissemination of disinformation and fabricated content on social media is growing. Yet little is known of what the functional Twitter data analysis methods are for languages (such as Finnish) that include word formation with endings and word stems together with derivation and compounding. Furthermore, there is a need to understand which themes linked with misinformation—and the concepts related to it—manifest in different countries and language areas in Twitter discourse. To address this issue, this study explores misinformation and its related concepts: disinformation, fake news, and propaganda in Finnish language tweets. We utilized (1) word cloud clustering, (2) topic modeling, and (3) word count analysis and clustering to detect and analyze misinformation-related concepts and themes connected to those concepts in Finnish language Twitter discussions. Our results are two-fold: (1) those concerning the functional data analysis methods and (2) those about the themes connected in discourse to the misinformation-related concepts. We noticed that each utilized method individually has critical limitations, especially all the automated analysis methods processing for the Finnish language, yet when combined they bring value to the analysis. Moreover, we discovered that politics, both internal and external, are prominent in the Twitter discussions in connection with misinformation and its related concepts of disinformation, fake news, and propaganda.

Abstract
Risk perception and consequently engagement in behaviors to avoid illness often do not match actual risk of infection, morbidity, and mortality. Unrealistic optimism occurs when individuals falsely believe that their personal outcomes will be more favorable than others' in the same risk category. Natural selection could favor overconfidence if its benefits, such as psychological resilience, outweigh its costs. However, just because optimism biases may have offered fitness advantages in our evolutionary past does not mean that they are always optimal. The current project examined relationships among personal risk for severe COVID-19, risk perceptions, and preventative behaviors. We predicted that those with higher risk of severe COVID-19 would exhibit unrealistic optimism and behave in ways inconsistent with their elevated risk of morbidity and mortality. Clinical risk scores for severe COVID-19 were calculated and compared with COVID-19 threat appraisal, compliance with shelter-in-place orders (March 13–May 22, 2020) and travel restrictions, compliance with public health recommendations, and potential covariates like self-rated knowledge about COVID-19 in a robust dataset including 492 participants from McLennan County, TX, USA. While those with high clinical risk acknowledged their greater likelihood of experiencing severe illness if infected, they actually reported lower perceived likelihood of becoming infected in the first place. While it is possible that those with higher clinical risk scores truly are less likely to become infected, the pattern and significance of these results held after controlling for possible occupational exposure, household size, and other factors related to infection probability. Higher clinical risk also predicted more recent travel within Texas and lower distress during the pandemic (i.e., feeling less stressed, depressed, and helpless). Additional behavioral data suggested that those with higher clinical risk scores did not generally behave differently than those with lower scores during the shelter-in-place order. While unrealistic optimism may provide some short-term psychological benefits, it could be dangerous due to improper assessment of hazardous situations; inferring that optimism bias has evolutionary origins does not mean that unrealistic optimism is “optimal” in every situation. This may be especially true when individuals face novel sources (or scales) of risk, such as a global pandemic.

Abstract
When meeting someone at zero acquaintance, we make assumptions about each other that encompass emotional states, personality traits, and even cognitive abilities. Evidence suggests individuals can accurately detect psychopathic personality traits in strangers based on short video clips or photographs of faces. We present an in-depth examination of this ability. In two studies, we investigated whether high psychopathy traits are perceivable and whether other traits affect ratings of psychopathic traits in the sense of a halo effect. On the perceiver's end, we additionally examined how cognitive abilities and personality traits of the responders affect these ratings. In two studies (n1 = 170 community adults from the USA, n2 = 126 students from Australia), participants rated several targets on several characteristics of psychopathy, as well as on attractiveness, masculinity, sympathy, trustworthiness, neuroticism, intelligence, and extraversion. Results show that responders were generally able to detect psychopathy. Responders generally came to a consensus in their ratings, and using profile similarity metrics, we found a weak relation between ratings of psychopathy and the targets' psychopathy level as determined by the Psychopathy Checklist: Short Version. Trait ratings, though, were influenced by the ratings of other traits like attractiveness. Finally, we found accuracy in the perception of psychopathy was positively related to fluid intelligence but unrelated to emotion perception ability.

Abstract
According to the predictive processing framework, perception is geared to represent the environment in terms of embodied action opportunities as opposed to objective truth. Here, we argue that such an optimisation is reflected by biases in expectations (i.e., prior predictive information) that facilitate 'useful' inferences of external sensory causes. To support this, we highlight a body of literature suggesting that perception is systematically biased away from accurate estimates under conditions where utility and accuracy conflict with one another. We interpret this to reflect the brain's attempt to adjudicate between conflicting sources of prediction error, as external accuracy is sacrificed to facilitate actions that proactively avoid physiologically surprising outcomes. This carries important theoretical implications and offers new insights into psychopathology.
