Effects of matching climate change appeals to personal values.

The stronger people hold self-enhancing (that is, egoistic or hedonic) values, the less they tend agree with pro-environmental efforts. An exploratory (N = 901) and a confirmatory study (N = 404) examined the effectiveness of pro-environmental messages matched to individuals' values. Findings indicate that strong endorsement of self-transcendent (that is, altruistic or biospheric) values is associated with unspecific endorsement of pro-environmental messages, while individuals endorsing self-enhancement values respond positively only to value-matched appeals.

Cognitive Avoidance Is Associated with Decreased Brain Responsiveness to Threat Distractors under High Perceptual Load.

Cognitive coping strategies to deal with anxiety-provoking events have an impact on mental and physical health. Dispositional vigilance is characterized by an increased analysis of the threatening environment, whereas cognitive avoidance comprises strategies to inhibit threat processing. To date, functional neuroimaging studies on the neural underpinnings of these coping styles are scarce and have revealed discrepant findings. In the present study, we examined automatic brain responsiveness as a function of coping styles using functional magnetic resonance imaging. We administered a perceptual load paradigm with contemptuous and fearful faces as distractor stimuli in a sample of N = 43 healthy participants. The Mainz Coping Inventory was used to assess cognitive avoidance and vigilance. An association of cognitive avoidance with reduced contempt and fear processing under high perceptual load was observed in a widespread network including the amygdala, thalamus, cingulate gyrus, insula, and frontal, parietal, temporal, and occipital areas. Our findings indicate that the dispositional tendency to divert one's attention away from distressing stimuli is a valuable predictor of diminished automatic neural responses to threat in several cortical and subcortical areas. A reduced processing in brain regions involved in emotion perception and attention might indicate a potential threat resilience associated with cognitive avoidance.

Non-conscious processing of fear faces: a function of the implicit self-concept of anxiety.

BACKGROUND: Trait anxiety refers to a stable tendency to experience fears and worries across many situations. High trait anxiety is a vulnerability factor for the development of psychopathologies. Self-reported trait anxiety appears to be associated with an automatic processing advantage for threat-related information. Self-report measures assess aspects of the explicit self-concept of anxiety. Indirect measures can tap into the implicit self-concept of anxiety. METHODS: We examined automatic brain responsiveness to non-conscious threat as a function of trait anxiety using functional magnetic resonance imaging. Besides a self-report instrument, we administered the Implicit Association Test (IAT) to assess anxiety. We used a gender-decision paradigm presenting brief (17 ms) and backward-masked facial expressions depicting disgust and fear. RESULTS: Explicit trait anxiety was not associated with brain responsiveness to non-conscious threat. However, a relation of the implicit self-concept of anxiety with masked fear processing in the thalamus, precentral gyrus, and lateral prefrontal cortex was observed. CONCLUSIONS: We provide evidence that a measure of the implicit self-concept of anxiety is a valuable predictor of automatic neural responses to threat in cortical and subcortical areas. Hence, implicit anxiety measures could be a useful addition to explicit instruments. Our data support the notion that the thalamus may constitute an important neural substrate in biased non-conscious processing in anxiety.

#Insta personality: Personality expression in Instagram accounts, impression formation, and accuracy of personality judgments at zero acquaintance.

OBJECTIVE: This study examined personality expression, impression formation, and the consensus and accuracy of zero-acquaintance personality judgments that were based on people's Instagram accounts. METHOD: Self- and informant reports of the Big Five personality traits, self-esteem, and narcissism were collected for 102 Instagram users. Screenshots were taken of Instagram users' profiles, including up to the 102 latest available Instagram posts. A number of Instagram cues were objectively retrieved, counted, and rated by independent trained cue coders from the screenshots. 100 unacquainted observers then judged the Big Five traits, self-esteem, and narcissism on the basis of Instagram screenshots only. RESULTS: We identified Instagram account characteristics that were associated with users' personality traits (measured with self-reports, informant reports, and self-informant composites) and observers' zero-acquaintance personality judgments. Personality judgments that were based on Instagram accounts demonstrated consensus and significantly converged with Instagram users' Big Five traits, self-esteem, and narcissism across all three personality criteria. Averaged-observer accuracy correlations for self-informant composite scores ranged from r = .44 (p < .001) for extraversion to r = .25 (p = .013) for conscientiousness. CONCLUSIONS: Our findings provide insight into cue processes of online self-portrayal and impression formation on Instagram and the level of zero-acquaintance accuracy.

Age and context effects in personality development: A multimethod perspective.

Observing most pronounced personality trait changes during young adulthood raises the question whether the traits are more stable per se after young adulthood or whether greater stability of daily life contexts also contributes to smaller trait changes in older adults. In this longitudinal multimethod study, we tested the competing explanations of trait stability and context stability by examining (a) whether age differences in Big Five trait changes are less pronounced when younger and older people experience similar context conditions, in this case, college life and (b) whether people of similar age change differently in different contexts. Furthermore, based on dual-process models of personality and because previous research has relied on self-ratings, we examined whether assumed personality changes also occur in implicit measures and other-ratings of traits. The sample of 241 adults consisted of older students (Mage = 67.5 years), older age- and education-matched nonstudents (Mage = 67.7 years), and young students (Mage = 21.1 years). We obtained self-ratings, other-ratings, and implicit measures of Big Five traits at four time points over 2 years. The results replicated increases in self-ratings of emotional stability, open-mindedness, extraversion, and conscientiousness in young first-year students and demonstrated distinct patterns of change among older students and older nonstudents. Changes in other-ratings and implicit measures only partly mirrored changes in self-ratings of Big Five traits. The study highlights the importance of different measures of traits to better understand personality development beyond self-ratings, and that in some groups, substantial trait changes are possible beyond young adulthood.

Nosological Characteristics in Women with Social Media Disorder: The Role of Social Functional Impairment and Agreeableness.

Social media disorder (SMD) is a frequently occurring subtype of Internet-related disorders (IRD), which has recently become a focus of research. It is noticeable that women are among those affected, whose nosological characteristics need to be examined. A clinical sample of n = 294 women (14-68 years, M = 36.88 years) was generated. The questionnaire included questions about demography, IRD, SMD, personality traits, psychopathological distress, functional impairment and comorbid mental illnesses. IRD was found in 17.5 percent and SMD in 12.5 percent of women. Compared to women with global IRD Women with SMD reported lower scores on the personality traits neuroticism and agreeableness. They are more frequently functionally impaired in the social dimension, more often reported comorbid substance-dependency and less eating disorders. The results suggest that although have similar characteristics to the comparison group, women with SMD differ in their nosological characteristics from women with global IRD.

Minor and inconsistent differences in Big Five personality traits between vegetarians and vegans.

Most research examining individuals who follow different diets has combined vegetarians and vegans into a single group. To investigate whether this consolidation is justified, we analyzed possible differences between vegetarians and vegans for the Big Five personality traits in two studies. In our pre-study, we used data from a German convenience sample of 400 vegetarians and 749 vegans and found that vegans reported slightly higher scores in Openness compared to vegetarians (d = 0.22). In the preregistered main study, we used data provided by 1203 vegetarians and 128 vegans from the German Socio-Economic Panel Study; we found that vegetarians reported slightly higher scores in Neuroticism compared to vegans (d = 0.18) but did not differ in Openness. We found no differences in Conscientiousness, Extraversion, or Agreeableness in either study. Controlling for the socio-demographic variables of age, gender, and socio-economic status did not alter the pattern of results. Overall, these results suggest that there are no or only small differences in Openness or Neuroticism between vegetarians and vegans. Further studies utilizing very large, representative samples are needed to better understand the relationship between personality and diet groups.

Physicians' attitudes towards disclosure of payments from pharmaceutical companies in a nationwide voluntary transparency database: a cross-sectional survey.

OBJECTIVES: To investigate German physicians' attitudes towards and experiences with voluntary disclosure of payments by pharmaceutical companies in a public database and their impact on future decisions for or against disclosure. DESIGN: A national cross-sectional survey conducted in 2018 among physicians who voluntarily disclosed at least one payment in the German transparency regulation. SETTING: Retrospective paper-pencil questionnaire about attitudes towards and experiences with voluntary payment disclosures in the first (2015) and second (2016) years of the German transparency regulation. PARTICIPANTS: German physicians who disclosed either in the first year only, the second year only, or in both years of the transparency regulation. PRIMARY OUTCOMES: (1) The probability to disclose in 2016, predicted by physicians' experience of reactions from others in 2015, descriptive norms and attitudes towards transparency; (2) Frequency and (3) Content of reactions from others in 2015 compared with 2016. RESULTS: Data of 234 respondents were analysed (n=42, 45 and 147 physicians who disclosed in 2015, 2016 or both years, respectively). The probability to disclose in 2016 was not predicted by perceived reactions, norms or attitudes towards transparency (p>0.01). Most participants reported not to have received any reactions by patients (190/234, 81%), colleagues (128/234, 55%) or the private environment (153/234, 65%). Neither frequency nor content of reactions differed between the first and second years (scale 1-5; frequency: Mdn2015,2016 = 1.33 vs 1.00, rb=-0.17, p>0.01; content: Mdn2015,2016 = 3.00 vs 3.00, rb=0.19, p>0.01). However, media reporting, fear of reputational damage and a feeling of being defamed were mentioned as reasons for non-disclosure. CONCLUSIONS: While confirmatory analyses did not provide significant results, descriptive analyses showed that participants who voluntarily disclose payments mainly do not experience any reactions towards their disclosures but report fears about losing their reputation due to disclosures.

Coping With Anxiety: Brain Structural Correlates of Vigilance and Cognitive Avoidance.

Background: Individuals differ in their dispositional coping behavior when they are confronted with anxiety-provoking situations. Cognitive avoidance is characterized by a withdrawal from threatening information, whereas vigilance denotes the intensive search for threat-related information. Functional neuroimaging studies indicate alterations in brain responsivity to emotional stimuli as a function of cognitive avoidant and vigilant coping, but findings are partially discrepant. Studies on structural correlates of coping styles are scarce. Materials and Methods: By using structural magnetic resonance imaging, the present study examined the relationship between brain gray matter volume and coping strategies in 114 healthy individuals. Individual differences in vigilance and cognitive avoidance were measured by the Mainz Coping Inventory. Results: Exploratory whole-brain analyses were conducted. Cognitive avoidant coping significantly predicted reduced gray matter volume in the bilateral thalamus, whereas vigilant coping was associated with volumetric increases in the bilateral thalamus. These relationships remained significant when controlling for a potential influence of age, sex, depressive symptoms, and trait anxiety. Discussion: Our findings indicate that dispositional strategies to deal with anxiety-provoking situations are related to volumetric alterations in the thalamus, a brain structure that has been implicated in the mediation of attentional processes and alertness, and the anticipation of harm. The dispositional tendency to monitor the environment for potential threats (i.e., vigilance), appears to be associated with volumetric increases in the thalamus, whereas the dispositional inclination to divert one's attention away from distressing stimuli (i.e., cognitive avoidance) seems to go along with reductions in thalamic gray matter density.

The development of the rank-order stability of the Big Five across the life span.

Several studies have suggested that the rank-order stability of personality increases until midlife and declines later in old age. However, this inverted U-shaped pattern has not consistently emerged in previous research; in particular, a recent investigation implementing several methodological advances failed to support it. To resolve the matter, we analyzed data from two representative panel studies and investigated how certain methodological decisions affect conclusions regarding the age trajectories of stability. The data came from Australia (N = 15,465; Study 1) and Germany (N = 21,777; Study 2), and each study included four waves of personality assessment. We investigated the life span development of the rank-order stability of the Big Five for 4-, 8-, and 12-year intervals. Whereas Study 1 provided strong evidence for an inverted U-shape with rank-order stability declining past age 50, Study 2 provided more mixed results that nonetheless generally supported the inverted U-shape. This developmental trend held for single personality traits as well as for the overall pattern across traits; and it held for all three retest intervals-both descriptively and in formal tests. Additionally, we found evidence that health-related changes accounted for the decline in rank-order stability in older age. This suggests that if analyses are implicitly conditioned on health (e.g., by excluding participants with missing data on later waves), the decline in stability in old age will be underestimated or even missed. Our results provide further evidence for the inverted U-shaped age pattern in personality stability development but also extend knowledge about the underlying processes.

Why They Eat What They Eat: Comparing 18 Eating Motives Among Omnivores and Veg*ns.

While the diets of most people include meat, millions of individuals follow a meat-free diet. But why do people eat what they eat? Here we explored differences and commonalities in the eating motives of omnivores and veg*ns (i.e., both vegetarians and vegans). Specifically, we compared mean levels and rank order of 18 eating motives in two samples (Study 1: 294 omnivores, 321 veg*ns; Study 2: 112 omnivores, 622 veg*ns). We found that omnivores were more motivated than veg*ns by the eating motives of Traditional Eating and Habits, while veg*ns were more motivated by Animal Protection and Environmental Protection. Differences among groups in Health were inconsistent across studies. Despite these differences in mean levels, the rank order of the eating motives was very similar: Two of the top four eating motives of both diet groups in both studies were Liking and Health, while Social Norms, Social Image, and Religion were among the four least important motives of both groups. Overall, while we did find differences in the absolute importance of certain motives, we also found striking similarities in the relative importance of eating motives, suggesting that including a wide range of eating motives could be beneficial when examining dietary behaviors.

The Agony of Choice: Acceptance, Efficiency, and Psychometric Properties of Questionnaires With Different Numbers of Response Options.

Questionnaires are one of the most important tools in psychological assessment, yet the impact of different numbers of response options on psychometric properties of questionnaires is limited. This study extends existing research by analyzing respondents' acceptance of and the efficiency of different numbers of response options and replicate findings on reliability and validity. We studied these questions in 540 respondents who filled out the Big Five Inventory-2 and the Emotion Regulation Questionnaire. Two response options, 11 response options and the visual analog scale showed disadvantages in acceptance compared with the original number of response options. The completion time increased by 1.7s per item when moving from 2 to 11 response options. Cronbach's alpha (but not ordinal alpha based on polychoric covariance) was lowest for two response options. Validity was unaffected. Overall, compared with the typical choice of five or seven response options, fewer or more response options resulted in disadvantages.

Stability and Change in Diffusion Model Parameters over Two Years.

In recent years, mathematical models of decision making, such as the diffusion model, have been endorsed in individual differences research. These models can disentangle different components of the decision process, like processing speed, speed-accuracy trade-offs, and duration of non-decisional processes. The diffusion model estimates individual parameters of cognitive process components, thus allowing the study of individual differences. These parameters are often assumed to show trait-like properties, that is, within-person stability across tasks and time. However, the assumption of temporal stability has so far been insufficiently investigated. With this work, we explore stability and change in diffusion model parameters by following over 270 participants across a time period of two years. We analysed four different aspects of stability and change: rank-order stability, mean-level change, individual differences in change, and profile stability. Diffusion model parameters showed strong rank-order stability and mean-level changes in processing speed and speed-accuracy trade-offs that could be attributed to practice effects. At the same time, people differed little in these patterns across time. In addition, profiles of individual diffusion model parameters proved to be stable over time. We discuss implications of these findings for the use of the diffusion model in individual differences research.

Associations of the Big Five and locus of control with problem gambling in a large Australian sample.

Gambling may range from being a recreational leisure activity to a behavioral addiction. A rising number of gamblers experience adverse consequences from gambling, termed problem gambling, which may become a challenge for the individual and society. With the present research, we aimed to investigate the correlates of problem gambling. We used a large sample of more than 12,500 individuals (46% male, Mage = 48, SDage = 18) from the Household, Income, and Labour Dynamics in Australia (HILDA) Survey and analyzed sociodemographic and personality variables (Big Five, locus of control) as well as the extent of problem gambling. Findings showed that male sex and a lower level of education were related to problem gambling, but personality traits were predictive of problem gambling over and above sociodemographic variables. Specifically, a low level of emotional stability, an external locus of control, and, to a lesser extent, a low level of conscientiousness and a high level of extraversion were predictive of problem gambling, whereas openness and agreeableness were not. These results remained constant across various robustness analyses. Our findings reveal the importance of including personality traits when explaining gambling behavior.

Maladaptive Personality Traits and Their Interaction with Outcome Expectancies in Gaming Disorder and Internet-Related Disorders.

Gambling disorder and gaming disorder have recently been recognized as behavioral addictions in the ICD-11 (International Classification of Diseases, 11th edition). The association between behavioral addictions and personality has been examined before, yet there is a lack of studies on maladaptive traits and their relationship to specific outcome expectancies. In study 1, we recruited a community sample (n = 365); in study 2 a sample of treatment-seekers was enrolled (n = 208). Maladaptive personality traits were assessed by the brief form of the Personality Inventory for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition). Internet-related outcome expectancies were measured by the Virtual Expectancy Questionnaire. In the clinical sample, the Global Assessment of Functioning was additionally administered. Behavioral Addictions were closely associated with maladaptive traits that in turn were related to a poorer level of psychosocial functioning. There is evidence for an exacerbated risk of internet-related disorders when specific outcome expectancies and maladaptive traits interact. Implications for phenomenology and treatment are discussed.

Daily life processes predict long-term development in explicit and implicit representations of Big Five traits: Testing predictions from the TESSERA (Triggering situations, Expectancies, States and State Expressions, and ReActions) framework.

This study examined daily life processes and their contribution to long-term continuity and change in explicit and implicit representations of Big 5 traits. The TESSERA framework (Wrzus & Roberts, 2017) served as theoretical background to derive predictions on 3 linked research questions (RQ) regarding (a) trait-state associations (RQ1); (b) antecedents and consequences of personality states (RQ2); as well as (c) processes of personality development (RQ3). We assessed Big 5 traits using self-ratings (i.e., BFI-44) and implicit association tests 4 times across 2 years in a sample of 382 younger (Mage = 21.57 years) and older (Mage = 67.76 years) adults. We also assessed momentary processes in multiple waves of daily diaries (total M = 43.9 days) focusing on people's most memorable daily experience. As predicted in RQ1, all self-rated traits, and implicit associations of self with conscientiousness, agreeableness, or emotional stability predicted subsequent trait-relevant situations and states. Regarding RQ2 across all trait domains, momentary processes could be generalized as sequences of Triggering situations, Expectancies, States and State Expressions, and ReActions (i.e., TESSERA sequences). With respect to RQ3, states were associated with long-term changes in self-rated conscientiousness and agreeableness, and self-rated and implicitly measured extraversion. Our findings further support the assumption that momentary experiences in daily life can contribute to long-term Big 5 changes, and extend previous research by examining implicit self-concepts and changes therein. The findings highlight the role of triggering situations, expectancies, reactions, and reflection in personality development in addition to trait-relevant states.

Individual differences in anxiety and automatic amygdala response to fearful faces: A replication and extension of Etkin et al. (2004).

Trait anxiety refers to the stable tendency to attend to threats and experience fears and worries across many situations. According to the widely noticed, pioneering investigation by Etkin et al. (2004) trait anxiety is strongly associated with reactivity in the right basolateral amygdala to non-conscious threat. Although this observation was based on a sample of only 17 individuals, no replication effort has been reported yet. We reexamined automatic amygdala responsiveness as a function of anxiety in a large sample of 107 participants. Besides self-report instruments, we administered an indirect test to assess implicit anxiety. To assess early, automatic stages of emotion processing, we used a color-decision paradigm presenting brief (33 ms) and backward-masked fearful facial expressions. N = 56 participants were unaware of the presence of masked faces. In this subset of unaware participants, the relationship between trait anxiety and basolateral amygdala activation by fearful faces was successfully replicated in region of interest analyses. Additionally, a relation of implicit anxiety with masked fear processing in the amygdala and temporal gyrus was observed. We provide evidence that implicit measures of affect can be valuable predictors of automatic brain responsiveness and may represent useful additions to explicit measures. Our findings support a central role of amygdala reactivity to non-consciously perceived threat in understanding and predicting dispositional anxiety, i.e. the frequency of spontaneously occurring anxiety in everyday life.

Personality and eating habits revisited: Associations between the big five, food choices, and Body Mass Index in a representative Australian sample.

OBJECTIVE: Personality traits are related to health and health-related behavior such as eating habits. However, results are inconsistent regarding exactly which traits are related to eating habits. The eating habits assessed across studies are also not easily comparable, as they are based on different food items and on different computational methods. This study investigated eating habits and their relationship to both the Big Five personality traits and Body Mass Index (BMI; an objective criterion of health status) in a representative Australian sample. METHOD: Participants were 13,892 adults from the Household, Income and Labour Dynamics in Australia survey. An analysis of 14 food items yielded three salient eating habits: consuming carbohydrate-based food (e.g., bread, pasta, snacks), meat (e.g., red meat, poultry), and plant-based food and fish (e.g., vegetables, fruits, legumes, fish). RESULTS: These three eating habits showed differential associations with personality and BMI. Eating plant-based food and fish was positively associated with openness, conscientiousness, and emotional stability in hierarchical regression analyses (controlling for sociodemographic factors and other personality traits). By contrast, consuming meat was negatively associated with openness and emotional stability, and positively associated with extraversion. Consuming carbohydrate-based food was negatively associated with conscientiousness, extraversion, and emotional stability. BMI was negatively related to conscientiousness and emotional stability and positively associated with agreeableness; BMI was related to all three eating habits. CONCLUSION: The present findings highlight the links between personality and individual health-related behavior. Implications and recommendations for the further study of individual differences in eating habits are discussed.

A Longitudinal Field Investigation of Narcissism and Popularity Over Time: How Agentic and Antagonistic Aspects of Narcissism Shape the Development of Peer Relationships.

Grandiose narcissism has been linked to initial popularity but to later unpopularity in peer groups and laboratory contexts. Do these effects on peer relationships also emerge in larger real-life contexts and what are the underlying behavioral processes (i.e., behavioral expressions, interpersonal perceptions)? Using data from the longitudinal CONNECT field study (N = 126), we investigated effects of agentic and antagonistic aspects of grandiose narcissism on emerging popularity in a complete peer network. A cohort of psychology first-year students was assessed with a quasiexperimental, experience-sampling methodology involving online surveys, diaries, and behavioral observations. In contrast to previous laboratory research, narcissism was unrelated to popularity at the level of zero-order correlations. However, results indicated that (a) an agentic behavioral pathway fostered popularity across time, and an antagonistic behavioral pathway drove the long-term decline in popularity, and (b) the two pathways were differentially related to agentic (admiration) and antagonistic (rivalry) aspects of narcissism.
