Effects of positive and negative affect inductions on interpretive and response bias.

Affective states and interpretations of ambiguous stimuli are inherently related constructs, although effects of induced affective states on interpretive and response biases have not been comprehensively explored. The present study examined the relationship between induced affective states and interpretive and response bias in a sample of 189 undergraduates. Participants completed an online study in which they were randomized into one of two mood induction conditions and subsequently completed an interpretive bias task. Results demonstrated significant condition differences in affect after the mood induction; the positive induction condition demonstrated significantly more positive mood and the negative condition demonstrated more negative mood. A significant difference between conditions emerged with respect to positive interpretive bias for non-social scenarios, with the positive mood induction condition demonstrating more positive interpretive bias to non-social situations than the negative induction condition (p = .04). The negative induction condition demonstrated significantly greater negative response bias for social scenarios (p = .03) and, unexpectedly, a significantly higher positive response bias for non-social scenarios (p = .05). Findings offer some support for the notion that inducing positive affect may promote more positive interpretations of ambiguous scenarios.
