Abstract
OBJECTIVE Disintegration is a recently proposed broad, trait-like reconceptualization of the proneness to psychotic-like experiences/behaviors. METHODS We tested the assumption that the 6-factor model (Five-Factor traits plus Disintegration) was the most adequate one and that it was invariant across clinical and non-clinical populations. The clinical sample (n = 161) consisted of patients who had at least one psychotic episode, duration of illness less than 10 years, currently in remission. The general population (n = 409) was matched with the patient sample by age, gender, and education. NEO PI-R and DELTA were used to measure personality dimensions in both samples. Invariance of one to six-factor solutions was tested by Exploratory Structural Equation Modeling. RESULTS We found that: (a) several criteria for deciding on the number of factors to retain converged to the conclusion that the assumed 6-factor model was the most adequate one, (b) the assumed factorial structure appeared to satisfy the criteria for the scalar invariance across the two samples, (c) all nine Disintegration subdimensions separated from the Big Five, forming the Disintegration factor, and (d) Disintegration was unrelated to Openness. CONCLUSION The Big Five personality structure-complemented with disintegration-was invariant across individuals from the general population and patients with psychosis.

Sound-induced flash illusions at different spatial locations were affected by personality traits. Atten Percept Psychophys 2023; 85:463-473.

Abstract
Sound-induced flash illusion (SiFI) is an auditory-dominated effect in which observers will misperceive the number of flashes due to simultaneously presented beeps, which includes fission and fusion illusions. Although several individual differences have been found in SiFI, little is known about the effect of personality traits. In the present study, we presented flashes in near space and beeps in far space (Vnear_Afar) and flashes in far space and beeps in near space (Vfar_Anear) to better approximate the real world. We collected 103 participants' Big Five questionnaire results and their SiFI task performance to investigate the difference in trait level on the SiFI in the performance of accuracy, d' and c. The results show that all five personality traits had certain effects on the SiFI to different degrees, and different personality traits played different roles in the fission illusion and fusion illusion. The high agreeableness group was more prone to the fission illusion, and the report criteria were less strict. The report criteria of the low neuroticism group were stricter for the fusion illusion. The extraversion, conscientiousness and low openness groups were more prone to the fusion illusion in the Vnear_Afar condition than in the Vfar_Anear condition. The study indicated that personality traits were important but easily overlooked factors in multisensory illusion, which might make a difference between the fission illusion and the fusion illusion.

Levels of neuroticism can predict attentional performance during cross-modal nonspatial repetition inhibition. Atten Percept Psychophys 2022; 84:2552-2561.

Abstract
Inhibition of return (IOR) refers to the slower response to targets presented at previously attended locations, and such repetition-induced inhibition has been found to be differentially associated with personality traits. Although it has been well documented how personality traits affect spatial IOR, a mechanism associated with the attentional orienting network, there is not yet a consensus as to the relationship between personality traits and nonspatial repetition inhibition, a mechanism associated with the attentional executive network. The present study herein examined how the Big Five personality traits relate to cross-modal nonspatial repetition inhibition. Participants completed the NEO-PI-R and performed a cross-modal nonspatial repetition inhibition task built on the prime-neutral cue-target paradigm, in which the relationships of the identities and modalities between the prime and the target were manipulated. The results showed a significant nonspatial inhibitory effect and the effect was larger under the visual-auditory condition than under the auditory-visual condition. More importantly, neuroticism was associated with decreased cross-modal nonspatial inhibitory effect, presumably due to impaired attentional control. However, such a result was only found in the visual-auditory condition. We propose that retrieving previous prime representations under the visual-auditory condition requires a large consumption of cognitive resources, making inhibitory control more difficult for individuals with high neuroticism. These findings provide new insight into the influence of personality traits on attentional performance requiring nonspatial inhibitory control and enrich the relationship between neuroticism and repetition-induced inhibition.

Abstract
Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit–seeking and cost–vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members’ subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd.

Individual differences in neuroticism personality trait in emotion regulation. J Affect Disord 2020; 265:468-474.

Abstract
BACKGROUND Higher neuroticism personality trait individuals have more negative mood states, more sensitive to negative information, and higher risk of mental illness. Good emotion regulation ability play an important role in healthy psychological, social and physical outcomes. Previous studies have suggested that higher neuroticism individuals have a diminished ability to regulate emotion regulation. Up to now, few studies investigate the neural basis between neuroticism and emotion regulation. METHOD In present study, we want to explore the neuroticism and the activity of some brain regions and functional amygdala connectivity (psycho-physiological interaction [PPI]) in a cognitive reappraisal task. Thus, 160 healthy young participants were scanned during a cognitive reappraisal task. RESULTS The results revealed that neuroticism scores showed a significant negative association with the activity of the dorsomedial prefrontal cortex (dmPFC), inferior frontal cortex and middle frontal cortex in regulation of negative emotion. PPI analyses revealed that neuroticism scores were negatively associated with amygdala-dmPFC connectivity in regulation of negative emotion. LIMITATION Only cognitive reappraisal were investigated in this study. Other emotion regulation strategies such as expressive suppression need to be explored in the future study. CONCLUSION These results may suggest that highly neurotic participants display diminished cognitive reappraisal and diminished control function of the dmPFC over the amygdala in regulation of negative emotion.

Abstract
OBJECTIVE Differences in myelination in the cortical mantle are important neurobiological mediators of variability in cognitive, emotional, and behavioral functioning. Past studies have found that personality traits reflecting such variability are linked to neuroanatomical and functional changes in prefrontal and temporo-parietal cortices. Whether these effects are partially mediated by the differences in intra-cortical myelin remains to be established. METHOD To test this hypothesis, we employed vertex-wise intra-cortical myelin maps in n = 1,003 people from the Human Connectome Project. Multivariate regression analyses were used to test for the relationship between intra-cortical myelin and each of the five-factor model's personality traits, while accounting for age, sex, intelligence quotient, total intracranial volume, and the remaining personality traits. RESULTS Neuroticism negatively related to frontal-pole myelin and positively to occipital cortex myelin. Extraversion positively related to superior parietal myelin. Openness negatively related to anterior cingulate myelin, while Agreeableness positively related to orbitofrontal myelin. Conscientiousness positively related to frontal-pole myelin and negatively to myelin content in the dorsal anterior cingulate cortex. CONCLUSIONS Intra-cortical myelin levels in brain regions with prolonged myelination are positively associated with personality traits linked to favorable outcome measures. These findings improve our understanding of the neurobiological underpinnings of variability in common behavioral dispositions.

Abstract
BACKGROUND The Perceived Stress Scale (PSS) is made up of two subscales but is typically used as a single summary measure. However, research has shown that the two subscales may have differential properties in older adults. OBJECTIVE To evaluate the internal consistency, test-retest reliability, and the concurrent and predictive validity for development of amnestic mild cognitive impairment (aMCI) of the positively-worded (PSS-PW) and negatively-worded (PSS-NW) subscale scores of the PSS in older adults. METHODS We recruited community residing older adults free of dementia from the Einstein Aging Study. Reliability of the PSS-PW and PSS-NW was assessed using Cronbach's alpha for internal consistency and intraclass correlation for one year test-retest reliability. Concurrent validity was evaluated by examining the relationship between the PSS subscales and depression, anxiety, neuroticism, and positive and negative affect. Predictive validity was assessed using multivariate Cox regression analyses to examine the relationship between baseline PSS-PW and PSS-NW score and subsequent onset of aMCI. RESULTS Both PSS-PW and PSS-NW showed adequate internal consistency and retest reliabilities. Both the PSS-PW and PSS-NW were associated with depression, neuroticism, and negative affect. The PSS-NW was uniquely associated with anxiety while the PSS-PW was uniquely associated with positive affect. Only the PSS-PW was associated with a statistically significant increased risk of incident aMCI (HR = 1.27; 95% CI: 1.06-1.51 for every 5-point increase in PSS-PW). CONCLUSIONS Evaluating the separate effects of the two PSS subscales may reveal more information than simply using a single summation score. Future research should investigate the PSS-PW and PSS-NW as separate subscales.

Abstract
The five-factor model (FFM) is a widely used taxonomy of human personality; yet its neuro anatomical basis remains unclear. This is partly because past associations between gray-matter volume and FFM were driven by different surface-based morphometry (SBM) indices (i.e. cortical thickness, surface area, cortical folding or any combination of them). To overcome this limitation, we used Free-Surfer to study how variability in SBM measures was related to the FFM in n = 507 participants from the Human Connectome Project. Neuroticism was associated with thicker cortex and smaller area and folding in prefrontal–temporal regions. Extraversion was linked to thicker pre-cuneus and smaller superior temporal cortex area. Openness was linked to thinner cortex and greater area and folding in prefrontal–parietal regions. Agreeableness was correlated to thinner prefrontal cortex and smaller fusiform gyrus area. Conscientiousness was associated with thicker cortex and smaller area and folding in prefrontal regions. These findings demonstrate that anatomical variability in prefrontal cortices is linked to individual differences in the socio-cognitive dispositions described by the FFM. Cortical thickness and surface area/folding were inversely related each others as a function of different FFM traits (neuroticism, extraversion and consciousness vs openness), which may reflect brain maturational effects that predispose or protect against psychiatric disorders.

Abstract
Individual differences in cognitive efficiency, particularly in relation to working memory (WM), have been associated both with personality dimensions that reflect enduring regularities in brain configuration, and with short‐term neural plasticity, that reflects task‐related changes in brain connectivity. To elucidate the relationship of these two divergent mechanisms, we tested the hypothesis that personality dimensions, which reflect enduring aspects of brain configuration, inform about the neurobiological framework within which short‐term, task‐related plasticity, as measured by effective connectivity, can be facilitated or constrained. As WM consistently engages the dorsolateral prefrontal (DLPFC), parietal (PAR), and anterior cingulate cortex (ACC), we specified a WM network model with bidirectional, ipsilateral, and contralateral connections between these regions from a functional magnetic resonance imaging dataset obtained from 40 healthy adults while performing the 3‐back WM task. Task‐related effective connectivity changes within this network were estimated using Dynamic Causal Modelling. Personality was evaluated along the major dimensions of Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. Only two dimensions were relevant to task‐dependent effective connectivity. Neuroticism and Conscientiousness respectively constrained and facilitated neuroplastic responses within the WM network. These results suggest individual differences in cognitive efficiency arise from the interplay between enduring and short‐term plasticity in brain configuration.

Abstract
ISSUE Introversion is one of the personality factors that has been shown to be associated with performance in medical school. Prior cross-sectional studies highlight performance evaluation differences between introverted and extraverted medical students, though the mechanisms and implications of these differences remain relatively unexplained and understudied. This gap in the literature has become more salient as medical schools are employing more interactive learning strategies into their curricula which may disproportionately challenge introverted learners. EVIDENCE In this article, we provide an overview and working definition of introversion as a valid construct occurring on a continuum. We apply a goodness of fit model to explore how various medical training contexts may be more or less challenging for introverted students and the potential consequences of a poor fit. As preliminary support for these hypothesized challenges, we share observations from students self-identified as introverts. Examples include introverted students feeling at times like misfits, questioning a need to change their identity to succeed in medical school, and being judged as underperformers. We offer pragmatic suggestions for improving the fit between introverted students and their training contexts, such as teachers and students pausing between a question being asked and the initial response being offered and teachers differentiating between anxious and introverted behaviors. We conclude with suggested areas for future qualitative and quantitative research to examine how medical school curricula and the teaching environment may be differentially impacting the learning and health of introverted and extraverted students. IMPLICATIONS Extraverted behaviors will continue to be an important part of medical training and practice, but the merits of introverted behaviors warrant further consideration as both medical training and practice evolve. Educators who make manageable adjustments to current teaching practices can improve the learning for both introverted and extraverted styles of academic engagement.

Abstract
The popularity of social networking sites, such as Facebook, has increased rapidly over the past decade, especially among youth. Consequently, the impact of Facebook use on mental health problems (e.g., depressive symptomatology) has become a recent area of concern. Yet, evidence for such a link has been mixed and factors that contribute to heterogeneity of findings have not been identified. In this study, we examined whether the association between Facebook use and depressive symptoms is moderated by individual factors (i.e., personality and sex). To this end, we measured Facebook use, depressive symptoms, and personality domains (i.e., extroversion and neuroticism) among 237 young adults. No direct association was found between Facebook use and depressive symptoms. However, for females with high neuroticism, more frequent Facebook use was associated with lower depressive symptoms. Our findings suggest a complex relationship between Facebook use and depressive symptomatology that appears to vary by sex and personality. Facebook use may be protective against depressive symptoms for female users with high levels of neuroticism, while Facebook use may be unrelated to depressive symptoms among males.

Abstract
BACKGROUND Physical exercise has the potential to affect cognitive function, but most evidence to date focuses on cognitive effects of fitness training. Cognitive exercise also may influence cognitive function, but many cognitive training paradigms have failed to provide carry-over to daily cognitive function. Video games provide a broader, more contextual approach to cognitive training that may induce cognitive gains and have carry over to daily function. Most video games do not involve physical exercise, but some novel forms of interactive video games combine physical activity and cognitive challenge. METHODS/DESIGN This paper describes a randomized clinical trial in 168 postmenopausal sedentary overweight women that compares an interactive video dance game with brisk walking and delayed entry controls. The primary endpoint is adherence to activity at six months. Additional endpoints include aspects of physical and mental health. We focus this report primarily on the rationale and plans for assessment of multiple cognitive functions. DISCUSSION This randomized clinical trial may provide new information about the cognitive effects of interactive videodance. It is also the first trial to examine physical and cognitive effects in older women. Interactive video games may offer novel strategies to promote physical activity and health across the life span.The study is IRB approved and the number is: PRO08080012ClinicalTrials.gov Identifier: NCT01443455.

Abstract
The DSM-5 proposal indicates that personality disorders (PDs) be defined as collections of maladaptive traits but does not provide a specific diagnostic method. However, researchers have previously suggested that PD constructs can be assessed by comparing individuals' trait profiles with those prototypic of PDs and evidence from the five-factor model (FFM) suggests that these prototype matching scores converge moderately with traditional PD instruments. The current study investigates the convergence of FFM PD prototypes with interview-assigned PD diagnoses in a sample of 99 homeless individuals. This sample had very high rates of PDs, which extends previous research on samples with more modest prevalence rates. Results indicated that diagnostic agreement between these methods was generally low but consistent with the agreement previously observed between explicit PD measures. Furthermore, trait-based and diagnostic interview scores evinced similar relationships with clinically important indicators such as abuse history and past suicide attempts. These findings demonstrate the validity of prototype methods and suggest their consideration for assessing trait-defined PD types within DSM-5.

Abstract
The present study explored facets of personality in a sample of pathological gamblers with ADHD (n = 52) and without ADHD (n = 43). Participants were assessed for psychopathology and gambling disorders using the Mini International Neuropsychiatric Interview, the National Opinion Research Center DSM Screen for Gambling Problems, and the Adult ADHD Self-Report Scale. Facets of personality were assessed using the NEO Personality Inventory-Revised. Group differences emerged across several facets of personality when analyzed using multivariate statistics. Although both groups experienced difficulties in several areas compared with norming data (e.g., greater depression, higher impulsivity, lower self-esteem and lower self-discipline), these facets of personality were more pronounced in pathological gamblers with ADHD. Most notable among these differences are tendencies for gamblers with ADHD to experience greater levels of emotional instability, interpersonal sensitivity and stress proneness. Pathological gamblers with ADHD also appear to experience lower self-esteem, greater difficulty being assertive and lower levels of self-discipline. Surprisingly, both groups were comparable on facets of impulsivity. These findings suggest that pathological gamblers diagnosed with adult ADHD may experience additional challenges compared with pathological gamblers without ADHD.

Abstract
BACKGROUND Monoamine oxidase A (MAOA) is an important enzyme that metabolizes monoamines such as serotonin, norepinephrine and dopamine in the brain. In prefrontal cortex, low MAOA binding is associated with aggression and high binding is associated with major depressive disorder (MDD) and also risk for recurrence of depressive episodes. In rodent models, low MAOA levels are associated with increased aggression and fear conditioning, and decreased social and exploratory investigative behaviors. Our objective was to measure MAOA binding in prefrontal cortex and concurrently evaluate a broad range of validated personality traits. We hypothesized that prefrontal MAOA binding would correlate negatively with angry-hostility, a trait related to aggression/anger, and positively with traits intuitively related to adaptive investigative behavior. METHOD Participants were aged 19-49 years, healthy and non-smoking. MAOA binding was measured with [11C]harmine positron emission tomography (PET) in prefrontal brain regions and personality traits were measured with the NEO Personality Inventory Revised (NEO PI-R). RESULTS Prefrontal MAOA binding correlated negatively with angry-hostility (r=-0.515, p=0.001) and positively with deliberation (r=0.514, p=0.001). In a two-factor regression model, these facets explained 38% of variance in prefrontal MAOA binding. A similar relationship was found in prefrontal cortex subregions. CONCLUSIONS We propose a new continuum describing the relationship between personality and MAOA: deliberate/thoughtful contrasting aggressive/impulsive. Additionally, the association between high MAOA binding and greater deliberation may explain why some people have moderately high levels of MAOA, although very high levels occur during MDD. In health, higher MAOA binding is associated with an adaptive personality facet.

Abstract
According to Eysenck's theory of Introversion-Extroversion (I-E), introverts demonstrate higher levels of basal activity within the reticular-thalamic-cortical loop, yielding higher tonic cortical arousal than Extraverts, who are described conversely as chronically under-aroused and easily bored. We hypothesized that higher scores on the trait of Extraversion would be associated with greater declines in psychomotor vigilance performance during prolonged wakefulness. We evaluated the relationship between I-E and overnight psychomotor vigilance performance during 77 h of continuous sleep deprivation in a sample of 23 healthy adult military personnel (19 men; four women), ranging in age from 20 to 35 years. At baseline, volunteers completed the Revised NEO Personality Inventory (NEO PI-R) and completed psychomotor vigilance testing at approximately 10-min intervals from 00:15 to 08:50 hours over three nights of continuous sleep deprivation. In addition, 12 participants received four repeated administrations of caffeine (200 mg) every 2 h each night. Analysis of covariance and stepwise multiple regression analyses showed that, above and beyond the effects of caffeine, higher Extraversion was significantly related to more extensive declines in speed of responding and more frequent attentional lapses, but only for the first overnight testing session. Sub-factors of Extraversion, including Gregariousness and higher Activity level were most predictive of these changes following sleep loss. These findings are consistent with Eysenck's cortico-reticular activation theory of I-E and suggest that individual differences in the trait of Extraversion confer some vulnerability/resistance to the adverse effects of sleep loss on attention and vigilance.

Abstract
The Five-factor model (FFM) provides a viable dimensional model of personality disorder assessment. Advantages of the FFM include the provision of a precise yet comprehensive description of both normal and abnormal personality functioning, the avoidance of the many limitations and problems inherent to the categorical diagnostic system, and the incorporation of basic science research on general personality structure and functioning into clinicians' description and understanding of personality disorders. We discuss three alternative instruments for the assessment of personality disorder from the perspective of the FFM. We also provide a method for diagnosing personality disorders and illustrate its application through a case study.

Abstract
In this psychometric study, we compared the recently developed Validity Scales from the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae, 1992b) with the MMPI-2 (Butcher, Dahstrom, Graham, Tellegen, & Kaemmer, 1989) Validity Scales. We collected data from clients (n = 74) who completed comprehensive psychological evaluations at a university-based outpatient mental health clinic. Correlations between the Validity Scales of the NEO-PI-R and MMPI-2 were significant and in the expected directions. The relationships provide support for convergent and discriminant validity of the NEO-PI-R Validity Scales. The percent agreement of invalid responding on the two measures was high, although the diagnostic agreement was modest (kappa = .22-.33). Finally, clients who responded in an invalid manner on the NEO-PI-R Validity Scales produced significantly different clinical profiles on the NEO-PI-R and MMPI-2 than clients with valid protocols. These results provide additional support for the clinical utility of the NEO-PI-R Validity Scales as indicators of response bias.

Abstract
OBJECTIVE Insecure attachment styles and certain personality characteristics (i.e., high levels of neuroticism) have been associated with eating pathology. However, previous research has not examined these variables simultaneously and has not examined possible mediating relationships between attachment and personality characteristics for disordered eating. Because personality characteristics have emerged as some of the most robust predictors of disordered eating, it was predicted that the link between attachment and disordered eating might be through personality styles. METHOD Participants included 85 female twins and triplets who took part in the Michigan State University Twin Study. Disordered eating, attachment style, and personality characteristics were assessed. Hierarchical linear models were used to examine relationships among the variables. RESULTS Overall, neuroticism, and extraversion to a lesser extent, mediated the relationship between insecure-resistant attachment and disordered eating. Specifically, higher scores on the neuroticism scale predicted more disordered eating and explained the relationship between insecure-resistant attachment and disordered eating. CONCLUSION These results suggest that relationships between attachment style and disordered eating are indirect, in that neuroticism fully mediates associations between insecure-resistant attachment and disordered eating.

Abstract
The objective of the study was to measure the impact of personality and other factors on the decision to initiate breastfeeding. Mothers were enrolled (24-96 hours postpartum) and were classified as fully breastfeeding, formula-feeding, or combination-feeding. A semi-structured interview about maternal sociodemographics and attitudes and a standardized personality inventory (NEO-PI-R) were conducted. Eighty-seven mothers completed the study: 50 breastfeeders, 6 combination feeders, and 31 formula feeders. Because of small numbers, combination-feeder mothers (n = 6) were excluded from analyses. Maternal age, marriage, ethnicity, and socioeconomic status were significantly associated with breastfeeding. Breastfeeding and formula-feeding groups differed on 3 personality domains: extraversion (53.3 breastfeeding vs 46.9 formula-feeding, P = .002), openness (51.6 vs 46.2, P = .008), and agreeableness (48.5 vs 41.5, P = .01). In a multiple variable logistic regression model, extraversion (P = .03) and openness (P = .003) remained significant. Sociodemographics, experiential factors, and specific personality characteristics of mother were independently associated with maternal feeding decision.

Abstract
We evaluated the convergent and discriminant validity of the Psychological Inventory of Criminal Thinking Styles (PICTS; Walters, 1995) in a group of 199 maximum security prisoners. As anticipated, the PICTS Confusion scale correlated with the Personality Assessment Inventory (PAI; Morey, 1991) Negative Impression scale, whereas the PICTS Defensiveness scale paralleled the PAI Positive Impression scale. Also as predicted, a greater portion of the PICTS thinking style scales correlated with the PAI Antisocial Features scale than correlated with the PAI Somatic Complaints, Anxiety, Depression, Mania, Paranoia, and Schizophrenia scales. When the PICTS composite scales were converged onto behavioral indexes, modest statistically significant relationships surfaced between the PICTS Reactive scale and a record of disciplinary infractions and between the PICTS Proactive scale and program completion.

Abstract
Participants (n = 22) completed the Revised NEO Personality Inventory (NEO PI-R) as part of an authentic job application. Protocols produced by this group were compared with "analog" participants (n = 23) who completed the NEO PI-R under standard instructions and again under instructions designed to mimic the test-taking scenario of the job applicants (the "fake-good" condition). Participants completing the NEO PI-R under fake-good instructions and the job applicants scored lower on the Neuroticism and higher on the Extraversion scales than did the participants responding under standard instructions. Analog participants in the fake-good condition scored higher on the Extraversion and lower on the Agreeableness scales than did the job applicants. These results suggest that outcomes from analog designs are generalizable to real-world samples where response dissimulation is probable.
