The university participant pool is a key resource for behavioral research, and data quality is believed to vary over the course of the academic semester. This crowdsourced project examined time of semester variation in 10 known effects, 10 individual differences, and 3 data quality indicators over the course of the academic semester in 20 participant pools (N = 2,696) and with an online sample (N = 737). Weak time of semester effects were observed on data quality indicators, participant sex, and a few individual differences-conscientiousness, mood, and stress. However, there was little evidence for time of semester qualifying experimental or correlational effects. The generality of this evidence is unknown because only a subset of the tested effects demonstrated evidence for the original result in the whole sample. Mean characteristics of pool samples change slightly during the semester, but these data suggest that those changes are mostly irrelevant for detecting effects.

The typical participant pool consists of undergraduates enrolled in introductory psychology courses that require students to complete some number of experiments over the course of the academic semester. Common variations might include using other courses to recruit participants or making study participation an option for extra credit rather than a pedagogical requirement. Research-intensive universities often have a highly organized participant pool with a participant management system for signing up for studies and assigning credit. Smaller or teaching-oriented institutions often have more informal participant pools that are organized ad hoc each semester or for an individual class.To avoid selection bias based on study content, most participant pools have procedures to avoid disclosing the content or purpose of individual studies during the sign-up process.However, students are usually free to choose the time during the semester that they sign up to complete the studies. This may introduce a selection bias in which data collection on different dates occurs with different kinds of participants, or in different situational circumstances (e.g., the carefree semester beginning versus the exam-stressed semester end).If participant characteristics differ across time during the academic semester, then the results of studies may be moderated by the time at which data collection occurs. Indeed, among behavioral researchers there are widespread intuitions, superstitions, and anecdotes about the "best" time to collect data in order to minimize error and maximize power. It is common, for example, to hear stories of an effect being obtained in the first part of the semester that then "d...
The use of ambulatory assessment (AA) and related methods (experience sampling, ecological momentary assessment) has greatly increased within the field of adolescent psychology. In this guide, we describe important practices for conducting AA studies in adolescent samples. To better understand how researchers have been implementing AA study designs, we present a review of 23 AA studies that were conducted in adolescent samples from 2017. Results suggest that there is heterogeneity in how AA studies in youth are conducted and reported. Based on these insights, we provide recommendations with regard to participant recruitment, sampling scheme, item selection, power analysis, and software choice. Further, we provide a checklist for reporting on AA studies in adolescent samples that can be used as a guideline for future studies.
The present study examined the development of self-esteem in a sample of emerging adults (N = 295) followed longitudinally over 4 years of college. Six waves of self-esteem data were available. Participants also rated, at the end of their 4th year, the degree to which they thought their self-esteem had changed during college. Rank-order stability was high across all waves of data (Mdn disattenuated correlation = .87). On average, self-esteem levels dropped substantially during the 1st semester (d =−.68), rebounded by the end of the 1st year (d = .73), and then gradually increased over the next 3 years, producing a small (d = .16) but significant mean-level increase in self-esteem from the beginning to the end of college. Individuals who received good grades in college tended to show larger increases in self-esteem. In contrast, individuals who entered college with unrealistically high expectations about their academic achievement tended to show smaller increases in self-esteem, despite beginning college with relatively high self-esteem. With regard to perceived change, 67% reported that their self-esteem increased during college, whereas 12% reported that it declined; these perceptions tended to correspond with actual increases and decreases in their self-esteem scale scores (β= .56). Overall, the findings support the perspective that self-esteem, like other personality characteristics, can change in systematic ways while exhibiting continuity over time.
We examined the life span development of openness to experience and tested whether change in this personality trait was associated with change in cultural activity, such as attending the opera or visiting museums. Data came from the Dutch Longitudinal Internet Study for the Social Sciences panel, which includes 5 personality assessments across a 7-year period of a nationally representative sample of 7,353 individuals, aged 16 to 95 years. Latent growth curve analyses indicated that on average, openness remained relatively stable in emerging adulthood before declining in midlife and old age. At each stage of life, there were significant individual differences in openness development, and changes in openness were correlated with changes in cultural activity. Autoregressive cross-lagged analyses indicated that increases in cultural activity precipitated increases in openness, and vice versa. These culture-openness transactions held across different age and education groups and when controlling for household income. We found less consistent codevelopmental associations between cultural activity and the other Big Five traits. We discuss the implications of these results for personality development theory and the role of cultural investment in personality trait change. (PsycINFO Database Record
Contempt is a powerful emotion. Marriages fail (Gottman, 1994), coworkers are shamed (Melwani & Barsade, 2011), terrorism is tended toward (Tausch et al., 2011). Despite its importance, contempt has not been investigated at the level of personality. The present research examines how our contemptuous reactions can be conceptualized and measured as a stable individual-difference variable with a range of theoretically predicted correlates. First, we introduce a measure of dispositional contempt, the tendency to look down on, distance, and derogate others who violate our standards. We then unpack the dynamics of dispositional contempt. Across six studies using self-report and emotion elicitation in student and MTurk samples (Ns = 165 to 1,368), we examined its (1) nomological network, (2) personality and behavioral correlates, and (3) implications for relationship functioning. Dispositional contempt was distinguished from tendencies toward related emotions and was most associated with dispositional envy, anger, and hubristic pride. Somewhat paradoxically, dispositional contempt was related to being cold and “superior,” with associations found with narcissism, other-oriented perfectionism, and various antisocial tendencies (e.g., Disagreeableness, Machiavellianism, racism), but was also related to being self-deprecating and emotionally fragile, with associations found with low self-esteem, insecure attachment, and feeling that others impose perfectionistic standards on oneself. Dispositional contempt predicted contemptuous reactions to eliciting film clips, particularly when targets showed low competence/power. Finally, perceiving one’s romantic partner as dispositionally contemptuous was associated with lower commitment and satisfaction. Taken together, results give a first look at the contemptuous person and provide a new organizing framework for understanding contempt.
