REGRESSION, CROSS
We first graphed trial acceptance rates by trial characteristics (i.e., the relative amounts to “You” and the Red Cross) and then examined acceptance rates for those with higher psychopathic trait scores (top 20%; note: this does not represent a clinical cut off but instead was an avenue through which to visualize behavioral patterns in the top quintile). We examined the relationships among prosocial behavior outcomes and psychopathic trait scores with Pearson correlations and then a multiple regression of prosocial behavior on psychopathic trait score, adjusting for age, race, sex and Red Cross visual analog scale score as well as the sex*psychopathic trait interaction if significant. We focused on LSRPS Factor 1 scores as our primary variable of interest in these analyses, in line with our prior work [
