Abstract
Although the need for social connection is fundamental, people approach this need through different strategies. Drawing from life history theory, the current research explored whether individuals' early-life experiences are associated with narrow/deep (depth), or broad/shallow (breadth) approach to social relationships. Three studies revealed that participants' childhood socioeconomic status (SES) interacts with perception of economic instability to create diverging preferences in social relationship pattern. Specifically, when economic instability was salient (chronic belief, Study 1; experimentally primed, Studies 2 and 3), individuals from lower-SES childhood preferred a narrower and deeper social network, whereas those from higher-SES childhood preferred a broader and shallower network. Taken together, the present research offers a novel understanding of depth- versus breadth-focused approach to social relationships from the perspective of life history theory.

Lin X, Wang R, Chen J. The reliability and validity of the brief measures of perceived childhood harshness and unpredictability: A revised Chinese version for emerging adults. CHILD ABUSE & NEGLECT 2024; 153:106810. [PMID: 38677177 DOI: 10.1016/j.chiabu.2024.106810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 04/01/2024] [Accepted: 04/18/2024] [Indexed: 04/29/2024]
Abstract
BACKGROUND Childhood harshness and unpredictability significantly shape life history strategies, as well as downstream psychological and behavioral patterns. However, prior research involving Chinese populations has suffered from inconsistent metrics and limited measurement items. OBJECTIVE We adapted the English version of Maranges et al.'s (2022) Harshness and Unpredictability Scale in Childhood, translating it into Chinese and assessing its reliability and validity. PARTICIPANTS AND SETTING Six groups of different college student samples have been collected and the Chinese version of the Harshness and Unpredictability scales has been revised in two separate studies. METHODS We evaluated the factor structure using both exploratory and confirmatory factor analyses, determined internal consistency, item discrimination, concurrent validity, and assessed gender measurement invariance through multiple CFAs. The test-retest reliability was subsequently established by assessing participants after a designated interval. RESULTS Both scales passed psychometric tests, including exploratory and confirmatory factor analyses, and exhibited strong internal consistency and item discrimination. Gender invariance in the measurements was also confirmed. CONCLUSIONS The Chinese version of the Childhood Harshness and Unpredictability Scale demonstrates high reliability and validity, making it suitable for deeper examinations into the relationship between early environments and life history strategies in Chinese contexts.

Navigating an unpredictable environment: the moderating role of perceived environmental unpredictability in the effectiveness of ecological resource scarcity information on pro-environmental behavior. BMC Psychol 2024; 12:261.

Abstract
BACKGROUND The global issue of ecological resource scarcity, worsened by climate change, necessitates effective methods to promote resource conservation. One commonly used approach is presenting ecological resource scarcity information. However, the effectiveness of this method remains uncertain, particularly in an unpredictable world. This research aims to examine the role of perceived environmental unpredictability in moderating the impact of ecological resource scarcity information on pro-environmental behavior (PEB). METHODS We conducted three studies to test our hypothesis on moderation. Study 1 (N = 256) measured perceived general environmental unpredictability, perceived resource scarcity and daily PEB frequencies in a cross-sectional survey. Study 2 (N = 107) took it a step further by manipulating resource scarcity. Importantly, to increase ecological validity, Study 3 (N = 135) manipulated the information on both ecological resource scarcity and nature-related environmental unpredictability, and measured real water and paper consumption using a newly developed washing-hands paradigm. RESULTS In Study 1, we discovered that perceived resource scarcity positively predicted PEB, but only when individuals perceive the environment as less unpredictable (interaction effect: 95% CI = [-0.09, -0.01], ΔR2 = 0.018). Furthermore, by manipulating scarcity information, Study 2 revealed that only for individuals with lower levels of environmental unpredictability presenting ecological resource scarcity information could decrease forest resource consumption intention (interaction effect: 95%CI = [-0.025, -0.031], ΔR2 = .04). Moreover, Study 3 found that the negative effect of water resource scarcity information on actual water and (interaction effect: 95%CI = [3.037, 22.097], ηp2 = .050) paper saving behaviors (interaction effect: 95%CI = [0.021, 0.275], ηp2 = .040), as well as hypothetical forest resource consumption (interaction effect: 95%CI = [-0.053, 0.849], ηp2 = .023) emerged only for people who receiving weaker environmental unpredictability information. CONCLUSION Across three studies, we provide evidence to support the moderation hypothesis that environmental unpredictability weakens the positive effect of ecological resource scarcity information on PEB, offering important theoretical and practical implications on the optimal use of resource scarcity to enhance PEB.

Abstract
Background eHealth literacy-the ability to obtain, understand, evaluate, and use health information from the Internet-is important to maintaining and improving personal health. Prior research found that people differ notably in the levels of eHealth literacy, and this study tests a theoretical account of some of those individual differences. Drawing on life history theory, we propose that low eHealth literacy is partly the outcome of people adopting a resource-allocation strategy emphasizing early and fast reproduction, namely, a fast life-history strategy. Methods We conducted a cross-sectional survey study (N = 1,036) that measured Chinese adult respondents' eHealth literacy, childhood environmental harshness and unpredictability, and fast life-history strategy. Covariates included health-information seeking online, self-rated health, sex, age, education level, and monthly income. Results Supporting a life-history explanation of eHealth literacy, childhood environmental harshness and unpredictability negatively predicted eHealth literacy through fast life-history strategy and mainly the insight-planning-control dimension of it. Harshness, not unpredictability, also directly and negatively predicted eHealth literacy after fast life-history strategy was controlled for. Conclusion Our findings suggest that the psychological mechanisms associated with human life-history strategies produce at least some of the individual differences in levels of eHealth literacy, including those related to neuroticism, socioeconomic status, self-rated health and social capital. Thus, a possible way to increase future generation's eHealth literacy and thereby their health is to reduce the harshness and unpredictability of the environment in which they grow up, thereby making them more likely to adopt a relatively slow life-history in their adulthood.

The long-term gut bacterial signature of a wild primate is associated with a timing effect of pre- and postnatal maternal glucocorticoid levels. MICROBIOME 2023; 11:165.

Abstract
BACKGROUND During development, elevated levels of maternal glucocorticoids (GCs) can have detrimental effects on offspring morphology, cognition, and behavior as well as physiology and metabolism. Depending on the timing of exposure, such effects may vary in strength or even reverse in direction, may alleviate with age, or may concern more stable and long-term programming of phenotypic traits. Maternal effects on gut bacterial diversity, composition, and function, and the persistence of such effects into adulthood of long-lived model species in the natural habitats remain underexplored. RESULTS In a cross-sectional sample of infant, juvenile, and adult Assamese macaques, the timing of exposure to elevated maternal GCs during ontogeny was associated with the gut bacterial community of the offspring. Specifically, naturally varying maternal GC levels during early but not late gestation or lactation were associated with reduced bacterial richness. The overall effect of maternal GCs during early gestation on the gut bacterial composition and function exacerbated with offspring age and was 10 times stronger than the effect associated with exposure during late prenatal or postnatal periods. Instead, variation in maternal GCs during the late prenatal or postnatal period had less pronounced or less stable statistical effects and therefore a weaker effect on the entire bacterial community composition, particularly in adult individuals. Finally, higher early prenatal GCs were associated with an increase in the relative abundance of several potential pro-inflammatory bacteria and a decrease in the abundance of Bifidobacterium and other anti-inflammatory taxa, an effect that exacerbated with age. CONCLUSIONS In primates, the gut microbiota can be shaped by developmental effects with strong timing effects on plasticity and potentially detrimental consequences for adult health. Together with results on other macaque species, this study suggests potential detrimental developmental effects similar to rapid inflammaging, suggesting that prenatal exposure to high maternal GC concentrations is a common cause underlying both phenomena. Our findings await confirmation by metagenomic functional and causal analyses and by longitudinal studies of long-lived, ecologically flexible primates in their natural habitat, including developmental effects that originate before birth.

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
To explore the impact mechanism of childhood adversity on problem behaviors of new street corner youth on campus, we surveyed 637 new street corner youth on campus and completed the Strengths and Difficulties Questionnaire, the Childhood Environment Scale, the Life History Strategies Scale, and the Dark Triad Scale. After controlling for gender and age of new street corner youth on campus, results revealed that childhood adversity was significantly and positively associated with problem behaviors. Mediation analysis showed that life history strategy mediated the association between childhood adversity and problem behaviors. Moreover, moderated mediation analysis further indicated that dark triad moderated the association between childhood adversity and life history strategy, as well as the association between life history strategy and problem behaviors. These findings suggest that interventions of life history strategy and dark triad may be effective means to affect problem behaviors of new street corner youth on campus.

Abstract
Exposure to environmental cues reflecting potential threats to future survivability is associated with a stronger endorsement of short-term mating strategies. Less is known, however, about the effects of safety and security cues. In four studies, we examined the effects of attachment-related security cues compared to neutral cues on preferences for short- and long-term mating strategies. Preferences were assessed using self-report and behavioral measures. In line with Life History Theory (LHT) and our hypotheses, exposure to attachment-related security cues was mainly associated with a stronger preference for long-term mating strategies and a weaker preference for short-term strategies. Our internal meta-analysis of the experimental security manipulations across studies provided further support for the association between state attachment security and endorsement of mating strategies. We also found some predictable effects of gender and relationship status. Implications for LHT and attachment theory are discussed. (139 words).

Abstract
Guided by principles from life-history theory, theories of adaptive calibration provide an overarching theoretical framework for understanding the developmental roots of impulsivity and externalizing psychopathology. The current research provides evidence for robust associations between perceptions of childhood unpredictability, delay discounting (Studies 1a and 1b), and adult externalizing traits and behaviors (Study 2). Both associations were observed while controlling for perceptions of the harshness of childhood environments, as well as a range of demographic characteristics. The association with externalizing traits and behavior was observed over and above current mood and depressive symptoms. Study 2 also replicated a previously documented association between changes in maternal employment, residence, and cohabitation during childhood and externalizing behavior and, furthermore, suggested that this association was mediated by perceptions of unpredictability. These studies provided no evidence for links between perceived childhood unpredictability and basic forms of risk-taking (Studies 1a and 1c). This research adds to a growing body of work leveraging principles from life-history theory to demonstrate links between childhood experiences, impulsivity, and potentially debilitating forms of mental illness. This work also highlights the value of assessing people's perceptions of their childhood environments.

Abstract
Although research has examined and supported the role of environmental adversity in career decision-making, little is known about the prediction power of childhood environmental adversity for career decision-making. To provide guidance for early career interventions, particularly in disadvantaged populations, the current study drew on life history theory and used a sample of U.S. college students ( n = 310) and a sample of U.S. noncollege individuals during emerging adulthood ( n = 308) to examine a mediation model involving childhood unpredictability, childhood poverty, career decision ambiguity aversion, and career decision-making difficulty. The results support the mediation of ambiguity aversion in the positive predictions of childhood unpredictability for all four factors of career decision-making difficulty. However, the results do not support the indirect predictions of childhood poverty for all four factors of career decision-making difficulty through ambiguity aversion but support the direct prediction of childhood poverty for lack of readiness. Therefore, the current study illuminates the importance of a predictable family environment during childhood for career decision-making during emerging adulthood and provides implications for the validity of life history theory in career decision-making, the development of ambiguity aversion, and early career interventions. Implications and future directions of research regarding childhood poverty are also discussed.

Abstract
INTRODUCTION Because greed is associated with various destructive outcomes, understanding the developmental precursors to dispositional greed in adolescence is of great importance. However, there are few empirical studies on this topic. The current study aimed to examine the relationship between childhood socioeconomic status (CSES) and adolescent greed and the moderating effect of family size. Two competing hypotheses were proposed. One is the scarcity hypothesis, which claims that CSES may be negatively related to adolescent greed. Another is the luxury hypothesis, which proposes that the richer the environment one grew up in, the more likely one is to develop dispositional greed. METHOD A cross-sectional sample of 3,200 adolescents (11-19 years old, 1,712 females, 1,356 males, and 132 of unknown gender) from North, Northwest, Middle and South China completed the questionnaire sets. A hierarchical multiple regression analysis was conducted. RESULTS CSES was positively correlated with dispositional greed, and the moderating effect of family size was significant. CONCLUSION The current study provides evidence supporting the luxury hypothesis over the scarcity hypothesis. In addition, adolescent dispositional greed increases with an increase in CSES when there is only one child in the family, while this is not the case for children with siblings. The theoretical and practical implications of the current study results as well as future research directions are discussed.

Abstract
Life History Theory posits early-life adversities affect personality development partway through sensitizing individuals to certain environmental cues, thus influencing the person’s responses to different stressors. We therefore hypothesized that life history strategy affects perceived distress and self-efficiency in coping through certain personality traits. The concept of the Dark Triad describes specific forms of personalities found to be associated with faster life strategies and perceived stress. Hence, the aim of our study was to examine the possible mediator role of the Dark Triad traits on the relationship between life strategies and perceived stress. A sample of 432 (133 males) under- and postgraduate students (aged between 18 and 34 years, M= 23.4, SD = 3.9) answered the Short-Form of the Arizona Life History Battery, the Mini-K, the Perceived Stress Scale, and the Short Dark Triad. Multiple linear regression and subsequent mediation analyses showed significant mediation effects of Dark Triad traits on both perceived distress and perceived coping. Our results indicate that these personality traits are part of the process in which faster life strategies predict higher level of perceived stress and lower levels of coping ability.

Abstract
Life history theory posits that behavioral adaptation to various environmental (ecological and/or social) conditions encountered during childhood is regulated by a wide variety of different traits resulting in various behavioral strategies. Unpredictable and harsh conditions tend to produce fast life history strategies, characterized by early maturation, a higher number of sexual partners to whom one is less attached, and less parenting of offspring. Unpredictability and harshness not only affects dispositional social and emotional functioning, but may also promote the development of personality traits linked to higher rates of instability in social relationships or more self-interested behavior. Similarly, detrimental childhood experiences, such as poor parental care or high parent-child conflict, affect personality development and may create a more distrustful, malicious interpersonal style. The aim of this brief review is to survey and summarize findings on the impact of negative early-life experiences on the development of personality and fast life history strategies. By demonstrating that there are parallels in adaptations to adversity in these two domains, we hope to lend weight to current and future attempts to provide a comprehensive insight of personality traits and functions at the ultimate and proximate levels.

Abstract
The association between low socioeconomic status (SES) and obesity is well documented. In the current research, a life history theory (LHT) framework provided an explanation for this association. Derived from evolutionary behavioral science, LHT emphasizes how variability in exposure to unpredictability during childhood gives rise to individual differences in a range of social psychological processes across the life course. Consistent with previous LHT research, the current findings suggest that exposure to unpredictability during childhood (a characteristic common to low SES environments) is associated with the adoption of a fast life-history strategy, one marked by impulsivity and a focus on short-term goals. We demonstrate that a fast life-history strategy, in turn, was associated with dysregulated weight-management behaviors (i.e., eating even in the absence of hunger), which were predictive of having a high body mass index (BMI) and being obese. In both studies, findings held while controlling for participants' current socioeconomic status, suggesting that obesity is rooted in childhood experiences. A serial mediation model in study 2 confirmed that effects of childhood SES on adult BMI and obesity can be explained in part by exposure to unpredictability, the adoption of a fast life-history strategy, and dysregulated-eating behaviors. These findings suggest that weight problems in adulthood may be rooted partially in early childhood exposure to unpredictable events and environments. LHT provides a valuable explanatory framework for understanding the root causes of obesity.

Abstract
The validity of the California Q-set measure of life history (LH) strategy was examined by conducting secondary analyses on longitudinal data that included the Q-sort measure of LH strategy at multiple ages (base year N = 106) and six measures of reproductive behavior. LH strategy Q-sort ratings showed stability from ages 14-23. Additionally, the ratings were found to be good prospective and age concurrent predictors of six reproductive behaviors. LH strategy as rated at age 14 was found to be a significant predictor of age of sexual debut, number of sexual partners, frequency of intercourse, number of abortions, age at birth of first child, and likelihood for having contracted venereal disease as measured up to age 32. Future research should test the further utility of the measure focusing on ways to reduce its cumbersomeness without reducing its ability to predict behavioral outcomes.

Abstract
Children vary in the extent to which their development is shaped by particular experiences (e.g. maltreatment, social support). This variation raises a question: Is there no single level of plasticity that maximizes biological fitness? One influential hypothesis states that when different levels of plasticity are optimal in different environmental states and the environment fluctuates unpredictably, natural selection may favor parents producing offspring with varying levels of plasticity. The current article presents a mathematical model assessing the logic of this hypothesis--specifically, it examines what conditions are required for natural selection to favor parents to bet-hedge by varying their offspring's plasticity. Consistent with existing theory from biology, results show that between-individual variation in plasticity cannot evolve when the environment only varies across space. If, however, the environment varies across time, selection can favor differential plasticity, provided fitness effects are large (i.e. variation in individuals' plasticity is correlated with substantial variation in fitness). Our model also generates a novel restriction: Differential plasticity only evolves when the cost of being mismatched to the environment exceeds the benefits of being well matched. Based on mechanistic considerations, we argue that bet-hedging by varying offspring plasticity, if it were to evolve, would be more likely instantiated via epigenetic mechanisms (e.g. pre- or postnatal developmental programming) than genetic ones (e.g. mating with genetically diverse partners). Our model suggests novel avenues for testing the bet-hedging hypothesis of differential plasticity, including empirical predictions and relevant measures. We also discuss several ways in which future work might extend our model.

Abstract
Hibbing et al. use evolutionarily derived logic to suggest that political attitudes are related to responses to negative features of the environment. We suggest that the authors focus too narrowly on the negative and contend, instead, that a more comprehensive evolutionary approach focusing on people's responses to threats and opportunities will better account for variation in political attitudes.
