Testing the effects of moral elevation on game behavior
CROSS
We compared Groups over Run using a mixed model analysis of covariance (ANCOVA) adjusting for age, race, and Red Cross visual analog scale score with fixed effects of Group (moral elevation vs. nature video), Run (1 vs. 2), sex (female vs. not female; as well as potential interactions with other fixed effects) and Group by Run interaction and random effect of subject. The two repeated measures on subjects were assumed to have an unstructured covariance structure estimating separate variance for each run and covariance between them thereby circumventing the more restrictive compound symmetric covariance assumption required in repeated measures ANCOVA. Beginning with the 3-way interaction between Group, Run and sex, non-significant higher order interactions (
