We investigated the causal relation between emotional awareness (EA) and suspiciousness, and whether this relation is moderated by gender. After inducing an unpleasant mood, we manipulated EA by having participants read one of two versions of a story (the high EA condition provided cues to what the participant was feeling and why, whereas the low EA condition did not). Following the manipulation, one sample of participants completed a measure of suspiciousness, and a second, independent sample of participants described their emotional state. Emotional Awareness Condition x Gender effects were obtained for suspiciousness and EA. Men in the low EA condition reported significantly higher levels of suspiciousness and lower levels of EA than men in the high EA condition. Women in both conditions reported equally high levels of EA, which were greater than those of men in both conditions, and the manipulation did not affect their levels of suspiciousness.
