P-values obtained from students t-test for independent groups.
P-values obtained from ANOVAs with pairwise comparisons of adjusted means, adjusted for age, gender, years of education and use of psychotropic medication controlled for.
ACS Affect Recognition, participants shown photos of facial expressions and asked to identify one of seven different emotions; ACS Prosody Face Matching, Participants listen to a recorded voice and asked to match the emotional tone of the speaker with one of six faces; ACS Prosody Pair Matching, Participants listen to a recorded voice and select an appropriate picture and emotion from four different pictures of two actors interacting; ACS Total Score, Derived by adding all of the correct matches of pictures from the affect naming and prosody tasks.
