Individuals Struggle to Change Their Perceived Personality in a First Impression Self-Gravity: Individuals Struggle to Change Their Perceived Personality in a First Impression by Ravin Alaei A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Psychology University of Toronto © Copyright by Ravin Alaei 2019 Self-Gravity: Individuals Struggle to Change their Perceived Personality in a First Impression Ravin Alaei Doctor of Philosophy Psychology University of Toronto 2019 Abstract People are motivated to change aspects of their personality traits and psychological research seems to document its regular occurrence. Nevertheless, most research has focused on whether people self-report that their personality traits have changed. Personality change is more than self- determined, however: People hope that changes to their personality are visible to others as well. Across seven studies, I therefore investigated whether people’s attempts to change their Big Five personality in a first impression are successful, focusing especially on extraversion. My work demonstrates that (i) individuals’ personality traits remain robustly visible in a first impression regardless of attempts to change, (ii) acting experience does not improve this ability, (iii) individuals’ traits can affect their evaluations more strongly than their attempts to change, and (iv) people attempting to change their personality in a first impression are largely unaware of how others truly judge them. This work therefore suggests that people struggle to control how their traits are perceived by others in a first impression. ii Acknowledgments Thank you to my supervisor, Nick Rule, for making me a better scientist and person. I am lucky to have received your mentorship and will carry your guidance with me. Thank you to my committee members, Jacob Hirsh and Geoff MacDonald, for dissecting my findings and for pushing me to think more deeply, as well as Erika Carlson, Norman Farb, and Judith Hall for their insightful feedback. I am also grateful for the Social Sciences and Humanities Research Council and the Department of Psychology for supporting my graduate work. Finally, thank you to my family and especially my mother—none of this would have been possible without their sacrifices. iii Table of Contents Acknowledgments

Hoff Q. Chelsea Song University of Illinois at Urbana-Champaign Purdue University Sif Einarsdóttir Daniel A. Briley and James Rounds University of Iceland University of Illinois at Urbana-Champaign Personality traits and vocational interests capture different aspects of human individuality that intersect in certain ways. In this longitudinal study, we examined developmental relations between the Big 5 traits and RIASEC vocational interests over 4 timepoints from late adolescence to young adulthood (age 16–24) in a sample of Icelandic youth (N ϭ 485) well-representative of the total student population. Results showed that interests and personality traits were similarly stable over time, but showed different patterns of mean-level change. There was evidence of personality maturation but a lack of cumulative changes in interest levels. For the most part, gender differences in developmental trends were minimal. In addition, latent growth curve analyses revealed broad and specific correlated changes between personality and interests. Changes in general factors of personality and interests were moderately related (r ϭ .32), but stronger correlated changes were found among specific personality–interest pairs that share situational content. Overall, results reveal how interests and personality are related across different types of continuity and change. While there was little correspondence between group-level changes, substantial correlated change occurred at the individual level.

  • Social Responses to Suppression 1
    SOCIAL RESPONSES TO SUPPRESSION 1 Social Responses to Expressive Suppression: The Role of Personality Judgments Allison M. Tackman Sanjay Srivastava University of Oregon In press, Journal of Personality and Social Psychology Note: This is a pre-publication manuscript. The final published version may differ slightly. SOCIAL RESPONSES TO SUPPRESSION 2 Abstract Why do people who suppress their emotion-expressive behavior have difficulty forming close and supportive relationships? Previous studies have found that suppression disrupts the dynamics of social interactions and existing relationships. We evaluated a complementary hypothesis: that suppression functions as a behavioral cue that leads others to form negative personality impressions of suppressors, even at zero acquaintance. In 2 experiments, participants reported personality judgments and other impressions of targets who either suppressed or expressed their emotion-expressive behavior to amusing or sad film clips. In replicated findings, targets who suppressed either amusement or sadness were judged as less extraverted, less agreeable, and more interpersonally avoidant and anxious than targets who expressed, and participants were less interested in affiliating with suppressors compared to expressers. Effects were amplified when targets suppressed amusement (compared to sadness) and when participants knew the emotional context (compared to when they did not) and thus could form expectations about what emotions targets should be showing. Extraversion and agreeableness judgments mediated the effect of suppression on participants’ disinterest in affiliating. In Study 2, which extended Study 1 in several ways, effects were pronounced for the enthusiasm aspect of extraversion and for the compassion aspect of agreeableness. We also found evidence that judgments of suppressors do not simply fall between neutral and fully-expressing targets; rather, judgments of suppressors are qualitatively different.

The identification of biological markers associated with personality in mild cognitive impairment could advance the early detection of Alzheimer’s disease. Methods: We used hierarchical multivariate linear models to quantify the interaction between per- sonality traits, state of cognitive impairment, and MRI biomarkers (gray matter brain volume, gray matter mean water diffusion) in the medial temporal lobe (MTL). Results: Over and above a main effect of cognitive state, the multivariate linear model showed sig- nificant interaction between cognitive state and personality traits predicting MTL abnormality. The interaction effect was mainly driven by neuroticism and its facets (anxiety, depression, and stress) and was associated with right-left asymmetry and an anterior to posterior gradient in the MTL.

Lewis Doctor of Philosophy Department of Psychology June 2014 Title: Searching for the Open Book: Exploring Predictors of Target Readability in Interpersonal Accuracy Interpersonal perception research has disproportionately focused on perceivers (who make judgments), while largely ignoring targets (who are judged). This study explored the role target characteristics play as perceivers judge their thoughts, emotions, and personality traits in brief get-to-know-you interactions between unacquainted college students. Funder’s Realistic Accuracy Model suggests that in order for a target to be readable that person must emit relevant cues that are made available to perceivers; thus, individual differences that are likely to be related to cue relevance and availability were investigated.

Annual Review of Psychology, 73. 10.1146/annurev-psych-020821-114927 Personality Annual Review Chapter 2 Abstract Personality psychology, which seeks to study individual differences in thoughts, feelings, and behaviors that persist over time and place, has experienced a renaissance in the last few decades. It has also not been reviewed as a field in the Annual Review since 2001 (Funder, 2001). In this chapter, we seek to provide an update, while also providing a meta-organizational structure to the field. In particular, personality psychology has a prescribed set of four responsibilities that it implicitly or explicitly tackles as a field: (a) describe what personality is— the units of analysis in the field; (b) document how it develops; (c) explain the processes of personality and why they affect functioning; and (d) provide a framework for understanding individuals and explaining their actions, feelings, and motivations.

Study 2 replicated these findings with regard to performance evaluation and reward giving using an experimental design that manipulated actor personality and held objective performance Abstract: constant.

PERSONALITY AND LIFE GOALS 2 Abstract The association between personality traits and motivational units, such as life goals, has been a longstanding interest of personality scientists. However, little research has investigated the longitudinal associations between traits and life goals beyond young adulthood. In the present study (N=251) we examined the rank-order stability of, and mean-level changes in, the Big Five and major life goals (Aesthetic, Economic, Family/Relationship, Hedonistic, Political, Religious, Social) from college (age 18) to midlife (age 40), as well as their co-development. Findings showed that personality traits and major life goals were both moderately-to-highly stable over 20 years. On average, there were mean-level increases in the Big Five and mean-level decreases in life goals over time.

  • Personality Changes Associated with Increasing Environmental Concerns
    Personality changes associated with increasing environmental concerns Christopher J. Hopwood, Ted Schwaba, Wiebke Bleidorn University of California, Davis Contact: [email protected] Acknowledgements The authors thank the German Institute for Economic Research for making the data available for this project. We have no funding sources or conflicts of interest to report. 2 Personality Change Environmental Concern Abstract Personal concerns about climate change and the environment are a powerful motivator of sustainable behavior. People’s level of concern varies as a function of a variety of social and individual factors. Using data from 58,748 participants from a nationally representative German sample, we tested preregistered hypotheses about factors that impact concerns about the environment over time. We found that environmental concerns increased modestly from 2009-2017 in the German population. However, individuals in middle adulthood tended to be more concerned and showed more consistent increases in concern over time than younger or older people. Consistent with previous research, Big Five personality traits were correlated with environmental concerns. We present novel evidence that increases in concern were related to increases in the personality traits neuroticism and openness to experience. Indeed, changes in openness explained roughly 50% of the variance in changes in environmental concerns. These findings highlight the importance of understanding the individual level factors associated with changes in environmental concerns over time, towards the promotion of more sustainable behavior at the individual level. Keywords Sustainability, Environment, Climate Change, Personality Traits, Personality Development 3 Personality Change Environmental Concern Climate change poses an existential threat to humankind. Sustainable behavior at the individual level is a primary tool for promoting environmental health (Chuang et al., 2020; Osbaldiston & Schott, 2012).

PERSONALITY CHANGE IN EMERGING AND YOUNG ADULTHOOD 2 Abstract Early adulthood is a time of substantial personality change characterized by large inter- individual diversity. To investigate the role of age in this diversity, the present study examined whether emerging adults differ from an older group of young adults in their Big Five personality development. By means of multi-group latent change modelling, two groups of 16- to 19-year-olds (n = 3,555) and 26- to 29-year-olds (n = 2,621) were tracked over the course of four years and compared regarding four aspects of personality change: Mean-level change, rank-order change, inter-individual differences in change, and profile change.
