Dispositional Traits, Characteristic Adaptations, and Narrative Identity Reconstructions in Individuals With Depersonalization and Derealization.

Depersonalization and derealization disorder (DPDR) is a debilitating condition. To date, little was known about the role of personality structure and of perceived social support and loneliness in DPDR. Three studies investigated, respectively: (i) broadband personality traits (five-factor model), maladaptive trait domains (PID-5), and perceived support and loneliness in individuals with self-reported DPDR (N = 160) versus a general population sample (N = 303), using network modeling; (ii) structure and interconnectivity of personality, perceived support and loneliness, and DPDR traits (frequency/duration) in individuals with self-reported DPDR (N = 160); (iii) characteristic adaptations and narrative identities in individuals with self-reported DPDR (N = 19), using thematic analysis. Study 1 found between-samples differences across several traits, especially psychoticism and negative affect. Differences in networks' global centrality, but not structures or edges, were also found. The graphical model in Study 2 showed a community of dissociative tendencies including DPDR traits and psychoticism. Study 3 highlighted the development of DPDR as a key life transition for those experiencing it, with narratives focusing on feelings of poor agency, isolation, and a disrupted sense of self. Individual differences in personality characterize DPDR, especially in psychoticism. Implications for theory and research are discussed.

Serum cortisol and neuroticism for post-traumatic stress disorder over 2 years in patients with physical injuries.

This study aimed to explore the relationships between serum cortisol levels, personality traits, and the development of Post-Traumatic Stress Disorder (PTSD) over 2 years among individuals with physical injuries. Participants were consecutively recruited from a trauma center and followed prospectively for 2 years. At baseline, serum cortisol levels were measured, and personality traits were categorized into five dimensions (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness), using the Big Five Inventory-10. The diagnosis of PTSD during follow-up (at 3, 6, 12, and 24 months post-injury) was determined using the Clinician-Administered PTSD Scale for DSM-5. Binary and multinomial logistic regression analyses were conducted to examine the interactions between cortisol levels, personality traits, and PTSD development. Among 923 patients analyzed, 112 (12.1%) were diagnosed with PTSD at some point during the study period, with prevalence rates decreasing from 8.8% at 3 months to 3.7% at 24 months post-injury. Direct associations between cortisol levels or personality traits and PTSD were not observed. However, a significant interaction between lower cortisol levels and higher Neuroticism in relation to PTSD risk was identified, especially during the early follow-up periods (3 to 6 months), but this association waned from the 12-month follow-up onward. Our findings reveal Neuroticism-dependent associations between serum cortisol levels and PTSD development, exhibiting temporal variations. These results suggest that PTSD development may be influenced by a complex, time-sensitive interplay of biological and psychosocial factors, underscoring the importance of considering individual differences in stress reactivity and personality in PTSD research and treatment.

Individual differences in sharing false political information on social media: Deliberate and accidental sharing, motivations and positive schizotypy.

False political information-misinformation or disinformation-is widely spread on social media. Individual social media users play a large part in this. However, only a minority actively share false material. It is important to establish what sets these individuals apart from those who do not, and why they do it. Motivations for sharing may vary and are likely to differ between people who share false material unknowingly and on purpose. In this paper we consider the extent to which individual differences in personality and other variables, and motivations for sharing, are associated with the likelihood of people sharing false political information both accidentally and deliberately. In a series of four studies (Ns = 614, 563, 627, 113) we examined predictors of sharing false political information using different methodological approaches. Across the four studies, a key finding was that positive schizotypy is associated with measures of sharing false information both accidentally and deliberately. Motivations for sharing political information online were also relevant, with sharing for reasons of 'raising awareness' appearing particularly important. Implications for research and practice are discussed.

Life is so Short, Future is so Long: The Relationship between Life History Strategies and People’s Metaphorical Perspectives on Time

Accruing evidence has attested to the plasticity of people’s metaphorical perspectives on the movement of events in time, which oscillate between the ego-moving perspective and the time-moving perspective contingent on, among others, perception of distance to the future by virtue of individual differences in lifestyle and personality. Building on and extending this avenue of inquiry, the current research investigated the relationship between life history strategy, another time-related construct, and the preferred perspective in the resolution of a temporally ambiguous question. Studies based on self-report (Study 1) and behavioral (Study 2) measures showed consistent results, such that individuals with a fast life history strategy and those who preferred the smaller-sooner reward tended to adopt the ego-moving perspective, whereas individuals with a slow life history strategy and those who preferred the larger-later reward tended to adopt the time-moving perspective. Examination of the priming effect of temporal perspectives on intertemporal decision-making revealed that differential perceptions of temporal distance underlay the strategy-time relationship (Study 3). Taken as a whole, the current findings suggested that individual differences in life history strategy may also influence people’s preferred perspective in the interpretation of ambiguous language related to time.

Unveiling the Power Play: How Newcomers’ Traits Shape Political Acumen Within Organizations

Political knowledge describes “an individual’s understanding of specific influential others’ relationships, demands, resources, and preferences” (Granger et al., 2020), is an often-overlooked dimension of learning how to fit into a new organization (Chao et al., 1994; Taormina, 1994). Moreover, newcomer research has been conducted independently of individual newcomer personality differences. To extend previous research, the present research examines newcomers’ Big Five personality traits and political knowledge as an immediate outcome of the process of newcomer adjustment. A 3-wave longitudinal study of 439 newcomers in 7 organizations examined Big Five personality traits as antecedents of political knowledge of the organization. The results suggested that among the Big Five traits, openness, neuroticism, and conscientiousness were positively related to apolitical knowledge of the organization. Overall, the results suggested that the Big Five are one of the key determinants of organizational political knowledge.

Personality Aspects and Attitudes About Animal Welfare Legislation

ABSTRACT The US Supreme Court recently debated and upheld a significant piece of farmed animal welfare legislation, Proposition 12, which was broadly supported by Californian voters. The goal of this study was to determine how individual differences in personality are related to attitudes about this legislation. We examined how ten lower-order aspects of the Big Five personality traits were related to Proposition 12 in an American sample (n = 802). The Openness aspect of Openness to Experience, the Withdrawal aspect of Neuroticism, and trait domain Agreeableness were consistently related to support for Proposition 12. Effects were not moderated by political orientation, region, gender, or age. Our results show that personality traits are not only an important factor in general political attitudes about animal welfare, but that they can predict people’s attitudes about particular pieces of animal welfare legislation. Results also highlight the importance of considering lower-order aspects for predicting animal welfare attitudes.

Individual differences and non-English-majors’ engagement in business English language classrooms in the Chinese university context

This study reports an investigative study of individual differences in personality, motivation, challenges, learning styles and strategies, needs and 55 non-English-majors’ engagement in business English language classrooms in a Chinese university, using two-stage surveys. The study finds positive affective factors in personality and motivation, though participants experienced challenges in learning business English vocabulary and improving English skills. Participants used different learning strategies and styles, and required varied helpful strategies for enhancing business English teaching and learning. Participants had high levels of cognitive engagement, behavioral engagement, emotional engagement, enjoyment, focus, and task familiarity in business English learning. Though participants still encountered problems, they reported learning gains in business English vocabulary expansion, improvement in business writing, workplace communication, business knowledge and culture, business reading, problem solving, listening, interest in English and critical thinking skills. This study is providing empirical evidence of individual differences with China’s non-English-major learners in business English learning and how the individual differences relate with engagement and learning outcomes. The study also implies for practice that business English teachers should adapt their teaching approach and strategies to accommodate to individual differences.

Interpersonal Problem Profiles of Personality and Psychopathology Constructs in Chinese Undergraduates and Offenders.

The interpersonal problem circumplex is extensively used in the field as an assessment framework for understanding the interpersonal implications of a range of personality and psychopathology constructs. The vast majority of this large literature has been conducted in Western convenience and clinical samples. We computed interpersonal problem structural summary parameters for a range of personality and psychopathology variables in two Chinese offender samples (N = 424 and N = 555) and one undergraduate sample (N = 511) to test how well findings from Western samples generalize to Chinese undergraduates and offenders. The results showed that findings in Western samples generalized reasonably well to Chinese young adult and forensic contexts, although the interpersonal profiles of external variables were less specific in Chinese samples. Compared with undergraduates, interpersonal distress has stronger associations with the mental health of offenders. This study further elaborates the interpersonal correlates of individual differences in personality and psychopathology across cultures and assessment contexts, and it also extends the literature examining interpersonal problems in forensic settings.

Characterizing stress processes by linking big five personality states, traits, and day-to-day stressors

The accumulation of day-to-day stressors can impact mental and physical health. How people respond to stressful events is a key mechanism responsible for the effects of stress, and individual differences in stress responses can either perpetuate or prevent negative consequences. Most research on daily stress processes has focused on affective responses to stressors, but stress responses can involve more than just affect (e.g., behavior, cognitions). Additionally, most research has studied the role of neuroticism in shaping those responses, but many other individual differences are associated with stress. In this study, we more broadly characterized daily stress processes by expanding the nomological networks of stress responses to include Big Five personality states. We also linked those stress responses to all Big Five traits, as well as individual differences in stress variety, severity, and controllability. We studied a sample of participants (N = 1,090) who reported on stressful events, their appraisal of events in terms of severity and controllability, and their Big Five personality states daily for 8–10 days (N = 8,870 observations). Multi-level structural equation models were used to separate how characteristics of the perceived stressful situation and characteristics of the person play into daily stress processes. Results showed that (1) all Big Five personality states shift in response to perceived stress, (2) all Big Five personality traits relate to average levels of perceived stress variety, severity, and controllability, (3) individual differences in personality and average perceived stress variety and perceived severity relate to the strength of personality state responses to daily stress, albeit in a more limited fashion. Our results point to new pathways by which stressors affect people in everyday life and begin to clarify processes that may explain individual differences in risk or resilience to the harmful effects of stress.

Effects of early predation and social cues on the relationship between laterality and personality.

Individual differences in laterality and personality are expected to covary, as emotions are processed differently by the two hemispheres, and personality involves emotional behavior. Fish species are often used to investigate this topic due to the large variability in personality and laterality patterns. While some species show a positive relationship between lateralization strength and boldness, others show a negative relationship, and some show no relationship. A new way to assess the robustness of such a relationship is to manipulate both laterality and personality to examine how this affects their relationship. To this end, we conducted a fully factorial design experiment manipulating predation and group size during early development. Results showed that the strength of laterality was influenced by predation threat, while social tendency and boldness were influenced by group size. These findings suggest that early life conditions can have an impact on laterality and social behavior. The relationship between laterality and personality traits, while present, was heavily influenced by the specific trial conditions but not by the different developmental conditions. In summary, the relationship between laterality and behaviors appears to be context-dependent, yet resilient to early environmental manipulations.

Personality and Well-Being Across and Within Relationship Status.

Trends of increasing singlehood call for understanding of well-being correlates across and within relationship status. While personality is a major predictor of well-being, descriptive trait profiles of singles have not been developed. In the present research (N = 1,811; 53% men; Mage = 29), single and partnered individuals completed measures of personality and well-being, including life, relationship status, and sexual satisfaction. Results revealed effects whereby single individuals were lower in extraversion and conscientiousness but higher in neuroticism. Additional facet analyses showed that singles were lower across all extraversion facets, but specifically lower in productiveness (conscientiousness facet) and higher in depression (neuroticism facet). Largely, personality was associated with well-being similarly for single and partnered people. Furthermore, relationship status accounted for variance in well-being above and beyond personality traits. Our results suggest individual differences in personality could play an important role in understanding well-being's link with relationship status.

Gender and education as factors for determining the verbal-visual affiliation of individuals

Gender and education are two of the socio-demographic characteristics that are studied to establish individual differences in personality. The purpose of the present research is to determine the susceptibility of individuals to the VVQ, adapted and modified from Kirby et al., and to show the influence of gender and education in the segmentation of verbalizers, visualizers, and dreamers. In the study, a valid and reliable instrument for measuring susceptibility to VVQ, prepared in advance by the author, was applied. The results of the analysis of variance (ANOVA) have showed a strong susceptibility of respondents to the Verbalizer Scale of women, as well as susceptibility to the Dreamer Scale of men. When considering the influence of education on VVQ, it was found that respondents with a master's degree were highly visual, and respondents with a doctoral degree were highly verbal. On Dreamer Scale, susceptibility was greatest again among respondents with a doctoral degree. The results of the analysis of covariance (ANCOVA) indicated that male advertising consumers with a master's degree were more receptive to the Verbalizer Scale, as were female respondents with a doctoral degree relative to all other target groups. These scientific results can be useful for advertisers, marketers, as well as specialists in cognitive psychology.

Individual differences in inattentional blindness.

People often fail to notice unexpected objects and events when they are performing an attention-demanding task, a phenomenon known as inattentional blindness. We might expect individual differences in cognitive ability or personality to predict who will and will not notice unexpected objects given that people vary in their ability to perform attention-demanding tasks. We conducted a comprehensive literature search for empirical inattentional blindness reports and identified 38 records that included individual difference measures and met our inclusion criteria. From those, we extracted individual difference effect sizes for 31 records which included a total of 74 distinct, between-groups samples with at least one codable individual difference measure. We conducted separate meta-analyses of the relationship between noticing/missing an unexpected object and scores on each of the 14 cognitive and 19 personality measures in this dataset. We also aggregated across personality measures reflecting positive/negative affectivity or openness/absorption and cognitive measures of interference, attention breadth, and memory. Collectively, these meta-analyses provided little evidence that individual differences in ability or personality predict noticing of an unexpected object. A robustness analysis that excluded samples with extremely low numbers of people who noticed or missed produced similar results. For most measures, the number of samples and the total sample sizes were small, and larger studies are needed to examine individual differences in inattentional blindness more systematically. However, the results are consistent with the idea that noticing of unexpected objects or events differs from deliberate attentional control tasks in that it is not reliably predicted by individual differences in cognitive ability.

Trait sensitivity to stress and cognitive bias processes in fish: A brief overview.

Like other animals, fish have unique personalities that can affect their cognition and responses to environmental stressors. These individual personality differences are often referred to as "behavioural syndromes" or "stress coping styles" and can include personality traits such as boldness, shyness, aggression, exploration, locomotor activity, and sociability. For example, bolder or proactive fish may be more likely to take risks and present lower hypothalamo-pituitary-adrenal/interrenal axis reactivity as compared to shy or reactive individuals. Likewise, learning and memory differ between fish personalities. Reactive or shy individuals tend to have faster learning and better association recall with aversive stimuli, while proactive or bold individuals tend to learn more quickly when presented with appetitive incentives. However, the influence of personality on cognitive processes other than cognitive achievement in fish has been scarcely explored. Cognitive bias tests have been employed to investigate the interplay between emotion and cognition in both humans and animals. Fish present cognitive bias processes (CBP) in which fish's interpretation of stimuli could be influenced by its current emotional state and open to environmental modulation. However, no study in fish has explored whether CBP, like in other species, can be interpreted as long-lasting traits and whether other individual characteristics may explain its variation. We hold the perspective that CBP could serve as a vulnerability factor for the onset, persistence, and recurrence of stress-related disorders. Therefore, studying fish's CBP as a state or trait and its interactions with individual variations may be valuable in future efforts to enhance our understanding of anxiety and stress neurobiology in animal models and humans.

Influence of personality on self-efficacy of work and supervision of children's schooling during COVID-19

This study evaluated the influence of personality factors and traits on the sense of self-efficacy in the combination of roles (work and supervision of children's school activities) in the context of COVID-19 in a representative sample of Ecuadorian adults of both sexes (n=400). Personality traits were assessed using Cattell's 16-PF personality test, and self-efficacy was measured using an adaptation of the Self-Efficacy Questionnaire. The results show that the five main personality factors of the 16-PF significantly predict self-efficacy and influence its variability by 12.7%. The factors Anxiety, Independence, and Toughness are the strongest predictors of self-efficacy. It was also found that the 16 personality traits assessed by the 16-PF questionnaire can predict 16.9% of self-efficacy. The most predictive traits were Stability, Openness to Change, Dominance, Privacy, and liveliness. These results suggest that individual personality differences allow individuals to better adapt to the various demands in a complicated environment such as COVID-19. These findings can be used to understand and support individuals when faced with complex environmental demands.

Individual Differences in Accent Imitation.

All talkers show some flexibility in their speech, and the ability to imitate an unfamiliar accent is a skill that shows vast individual differences. Yet the source of these individual differences, in particular whether they originate from perceptual, motor, or social/personality factors, is not yet clear. In the current study, we ask how individual differences in these factors predict individual differences in deliberate accent imitation. Participants imitated three accents, and attempts were rated for accuracy. A set of measures tracking individual differences in perceptual, motor, cognitive, personality, and demographic factors were also acquired. Imitation ability was related to differences in musical perception, vocal articulation, and the personality characteristic of "openness to experience," and was affected by attitudes towards the imitated talkers. Taken together, results suggest that deliberate accent imitation skill is modulated not only by core perceptual and motor skills, but also by personality and affinity to the talker, suggesting that some aspects of deliberate imitation are a function of domain-general constraints on perceptual-motor systems, while others may be modulated by social context.

Relationship between Personality Traits and Help-seeking Behaviour of Undergraduate Students

The individual knows that he or she needs assistance to solve the problem. Yet, seeking assistance may be associated with an open admission of failure and dependence on others. These anticipated psychological costs often hinder the seeking of help, which may result in the intensification of the problem. This study aimed to assess the relationship between personality traits and the help-seeking Behaviour of undergraduate students. The study employed a quantitative and descriptive research design. All the undergraduate students of the education department of district Lahore were the proposed population of the current research. The study sample comprised 538 undergraduate students using a stratified sampling technique. A questionnaire containing 54 items was used as a data collection instrument. Results showed a significant relationship between personality traits and the help-seeking Behaviour of undergraduate students. It was recommended that the potential utility of understanding and harnessing individual personality differences and their help-seeking Behaviour should be boosted among the students at the undergraduate level.

Giving Meaning to the Dark Triad: Comparison of Different Factor Structures of the Dirty Dozen Through Eight Regions of the World.

The traits of the dark triad (narcissism, psychopathy, and Machiavellianism) capture the individual differences in the aversive personality. The dark triad has shown significant relations with behaviors that affect people's lives. One of the best-known instruments to assess the dark triad is the Dirty Dozen. However, controversy continues over the use of one general dark triad score or, conversely, three different scores. This study aimed to investigate the factor structure of the Dirty Dozen across eight global regions. There were 11,477 participants in 49 countries grouped into eight regions. Different factor structures were studied using confirmatory factor analyses. Both the three-dimensional models and the bifactor models (symmetrical or traditional and non-symmetrical or bifactor-[S - 1]) showed a good fit to the data. The bifactor-(S - 1) models (with psychopathy or Machiavellianism as the reference factors) show adequate fit to the data, supported by the coherence of the factorial loadings and the bifactor indices. Regarding measurement invariance for both models, configural, metric, and scalar invariance were satisfied. The results indicate that it is not clear whether a psychopathy or Machiavellianism reference factor predominates in the Dirty Dozen. For both models, templates are provided to obtain standardized scores for applied researchers in the eight studied world regions until future studies offer a greater amount of validity evidence for this instrument.

Individual differences in cooperative and competitive play strategies.

Cooperation and competition are common in social interactions. It is not clear how individual differences in personality may predict performance strategies under these two contexts. We evaluated whether instructions to play cooperatively and competitively would differentially affect dyads playing a Pong video game. We hypothesized that instructions to play cooperatively would result in lower overall points scored and differences in paddle control kinematics relative to when participants were instructed to play competitively. We also predicted that higher scores in prosociality and Sportspersonship would be related to better performance during cooperative than competitive conditions. Pairs of participants played a Pong video game under cooperative and competitive instructions. During competitive trials, participants were instructed to score more points against one another to win the game. During the cooperative trials, participants were instructed to work together to score as few points against one another as possible. After game play, each participant completed surveys so we could measure their trait prosociality and Sportspersonship. Condition was a significant predictor of where along the paddle participants hit the ball, which controlled ball exit angles. Specifically, during cooperation participants concentrated ball contacts on the paddle towards the center to produce more consistent rebound angles. We found a significant correlation of Sex and the average points scored by participants during cooperative games, competitive games, and across all trials. Sex was also significantly correlated with paddle kinematics during cooperative games. The overall scores on the prosociality and Sportspersonship surveys were not significantly correlated with the performance outcomes in cooperative and competitive games. The dimension of prosociality assessing empathic concern was significantly correlated with performance outcomes during cooperative video game play. No Sportspersonship survey score was able to predict cooperative or competitive game performance, suggesting that Sportspersonship personality assessments are not reliable predictors of cooperative or competitive behaviors translated to a virtual game setting. Survey items and dimensions probing broader empathic concern may be more effective predictors of cooperative and competitive performance during interactive video game play. Further testing is encouraged to assess the efficacy of prosocial personality traits as predictors of cooperative and competitive video game behavior.

Personality Enhanced Emotion Generation Modeling for Dialogue Systems

Emotion plays a crucial role in human communication, as it adds depth and richness to conversations. In recent years, there has been growing interest in developing conversation systems with the ability to generate emotions. However, to create more engaging and realistic interactions, it is essential to consider the influence of personality on emotion generation. This paper proposes a novel approach that combines personality modeling with emotion generation for conversation systems. By incorporating personality traits into the emotion generation process, we aim to create more personalized and contextually appropriate emotional responses. Drawing from BigFive model and emotion computation techniques, our model takes into account individual differences in personality to generate emotions that align with each user’s unique characteristics. Experiments show that combining emotion modeling with personality in a dialogue system helps improve the performance of emotion generation models. Additionally, it is also verified that our approach outperforms other baselines on several metrics.
