Testing whether type of stimulus (moral elevation vs. Control) moderates the relationship between psychopathic traits and prosocial behavior
psychopathic
CROSS
We hypothesized that the relationship between psychopathic trait score and prosocial behavior would be moderated by the type of video viewed in between Runs. We evaluated the influence of moral elevation video condition exposure in comparison to control video condition, using a mixed model ANCOVA adjusting for age, race, and Red Cross visual analog scale score with fixed effects of Group (moral elevation vs. nature video), Psychopathic trait score (Factor 1), Run (1 vs. 2) and sex, and all their interactions, and random effect of subject with covariance structure as before. Beginning with the 4-way interaction between Group, Psychopathic trait score, Run and sex, non-significant interactions were sequentially removed and the model rerun. The model including three-way interaction (i.e., Group*Psychopathic trait score*Run), as the effect of interest, and all lower order terms was the most parsimonious entertained.
