People generally go on vacation to improve their life satisfaction. However, the association between life satisfaction and leisure travel is poorly understood, partly because of methodological limitations in previous research. In the present study, we examined the longitudinal association between life satisfaction and leisure travel using data from...

The present study examined the size and possible sources of life satisfaction differences between immigrants and natives in a sample of over 55,000 adults (aged 50+ years) across 16 European countries and Israel. Consistent with theory and prior research, immigrants reported lower life satisfaction than natives on average, while the size of the lif...

People have both positive and negative stereotypes about vegans. We developed a tool to measure them, examined self/other correlates. In press, Group Processes and Intergroup Relations.

Objective: Theory and anecdotal evidence suggest that people undergo psychological changes before and after religious conversion and deconversion. Yet, existing research provided inconclusive evidence. Here, we examined psychological change before, during, and after institutional conversion and deconversion in a large-scale longitudinal study. Me...

Do changes in religiosity beget changes in personality, or do changes in personality precede changes in religiosity? Existing evidence supports longitudinal associations between personality and religiosity at the between-person level, such that individual differences in personality predict subsequent individual differences in change in religiosity....

People responding to personality questionnaires rate themselves by comparing themselves to some reference group, but this reference group is typically not specified. In this study, we examined the differences between Big Five trait scores when people responded to trait questionnaires without a specified reference group, as is typical in personality...

This research tests the unique predictions of three different theoretical perspectives on the self-esteem benefits of religiosity: the religiosity-as-a-personal-relationship-with-a-higher-power perspective, the religiosity-as-a-resource perspective, and the religiosity-as-social-value perspective. To do so, we used random-intercept cross-lagged pan...

Objective: Climate change is a serious threat. Personality psychologists can help address this threat by understanding what kind of people tend to endorse proenvironmental attitudes and engage in sustainable behavior. Previous research supports reliable associations between proenvironmental attitudes and personality traits. However, this research...

People have a tendency to engage in social comparisons when evaluating and reporting on personality. This tendency and variation in who people compare their personality to is known as the reference group effect and has been largely discussed in cross-cultural research. However, reference group effects have implications beyond cross-cultural researc...

What personality traits characterize a typical parent? The purpose of this pre-registered study was to generate consensus-based Big Five personality prototypes of a typical father and mother through the eyes of 226 expecting parents and 281 nonparents (Total N = 507). We found that a prototypical father’s and mother’s personalities can be described...

The goal of this study was to identify the underlying latent dimensions that account for variation in sustainable behaviors (SBs) among American adults. Our strategy was to assess all of the SBs sampled in existing measures, as well as a number of other variables relevant to individual differences in SBs, in a community sample (N = 1234). Variation...

How do people’s religious beliefs and behaviors change over the course of adulthood? Previous research found rapid decreases in religiosity during young adulthood and rebounds in middle and late adulthood. However, secularization trends—if not accounted for—can bias or obscure age-graded changes in religiosity. Using longitudinal data from over 14,...

Proenvironmental attitudes and behaviors have been increasing over the past decade. In this study, we use longitudinal panel data from a nationally representative sample of the Swiss population (N=9,106) to replicate the finding that proenvironmental attitudes are linked with proenvironmental consumer behaviors, and present novel evidence that chan...

A large body of evidence indicates that personality traits show high rank-order stability and substantial mean-level changes across the lifespan. However, the majority of longitudinal research on personality development has relied on repeated assessments of self-reports, providing a narrow empirical base from which to draw conclusions and develop t...
