We replicated prior findings that a positive affect induction can improve creative performance (Baas et al., 2008) relative to a neutral control condition. We also tested whether humor improved creativity relative to both positive and neutral affect conditions. Participants were randomly assigned to either a positive, humor, or neutral affect induction condition with sets of ten memes as the mood induction stimuli. They were subsequently asked to complete two randomized divergent thinking… Show more

We replicated prior findings that a positive affect induction can improve creative performance (Baas et al., 2008) relative to a neutral control condition. We also tested whether humor improved creativity relative to both positive and neutral affect conditions. Participants were randomly assigned to either a positive, humor, or neutral affect induction condition with sets of ten memes as the mood induction stimuli. They were subsequently asked to complete two randomized divergent thinking creativity tasks. Compared to participants in the neutral condition, those in the positive affect condition generated significantly more creative ideas. The number of ideas generated by those in the humor condition did not differ from the number ideas in the positive affect condition. Implications and future directions are discussed. Show less

This study examined whether the age, ethnicity, sex, and weight of children influenced weight-based biases.

This study examined whether children follow unique victimization trajectories during elementary school and whether these paths predict differential psychological and physical health outcomes during high school. Participants included 1,073 children from the NICHD Study of Early Child Care and Youth Development. Peer victimization was assessed in the 3rd, 5th, 6th, and 9th grades, and psychological and physical health outcomes (e.g., depression, loneliness, internalizing problems, externalizing… Show more

This study examined whether children follow unique victimization trajectories during elementary school and whether these paths predict differential psychological and physical health outcomes during high school. Participants included 1,073 children from the NICHD Study of Early Child Care and Youth Development. Peer victimization was assessed in the 3rd, 5th, 6th, and 9th grades, and psychological and physical health outcomes (e.g., depression, loneliness, internalizing problems, externalizing problems, physical health markers, and health habits) were measured in the 9th grade. Growth mixture modeling revealed three groups: non-victims (n = 886), persistent victims (n = 52), and escaped victims (n = 70). Generally, persistent victims experienced poorer physical functioning and health, higher levels of psychological maladjustments, and poorer health habits (i.e., sleep problems, disordered eating) compared to non-victims. Using case–control matching, escaped victims and non-victims did not differ on health behaviors and most physical health measures, with the exception of adiposity. Escaped victims experienced higher levels of psychological issues than non-victims comparable to those observed in persistent victims. These findings underscore the heterogeneity of both victimization experiences and health outcomes following aversive peer experiences. Show less
