Emerging Adulthood Measured at Multiple Institutions 2: The Data

Collaborators from 32 academic institutions primarily in the United States collected data from emerging adults (N'raw''' = 4220, N'processed' = 3134). Participants completed self-report measures assessing markers of adulthood, IDEA inventory of dimensions of emerging adulthood, subjective well-being, mindfulness, belonging, self-efficacy, disability identity, somatic health, perceived stress, perceived social support, social media use, political affiliation, beliefs about the American dream, interpersonal transgressions, narcissism, interpersonal exploitativeness, beliefs about marriage, and demographics. The data are available at (https://osf.io/qtqpb/) with details about the study and contributors at our main EAMMi2 page (https://osf.io/te54b/). These data may be used to examine new research questions, provide authentic research experiences for students, and provide demonstrations for research and statistics courses

Stereotype Threat in Black College Students Across Many Operationalizations

According to stereotype threat theory, the possibility of confirming a negative group stereotype evokes feelings of threat, leading people to underperform in domains where they are stereotyped as lacking ability. This theory has immense theoretical and practical implications. However, many studies supporting it include small samples and varying operational definitions of “stereotype threat”. We address the first challenge by leveraging a network of psychology labs to recruit a large Black student sample (Nanticipated = 2700) from multiple US sites (Nanticipated = 27). We address the second challenge by identifying three threat-increasing and three threat-decreasing procedures that could plausibly affect performance and use an adaptive Bayesian design to determine which operationalization yields the strongest evidence for underperformance. This project should advance our knowledge of a scientifically and socially important topic: the conditions under which stereotype threat affects performance among current Black students in the United States
