These hypothesized biases were measured via an affective flanker task, a suboptimal priming task, and a judgment task about the probability of future events. In addition, affect was assessed at baseline and after the receipt of a reward. Results indicate that BAS was related to an enhanced orientation toward positivity and achievement cues. However, the hypothesis that BAS, positive affect, and enhanced achievement orientation are related to mania-proneness was generally not supported. Contrary to prediction, mania-prone participants exhibited higher levels of BIS, more negative affect, more predictions of negative events, and higher levels of threat perception, suggesting an overall propensity toward negative affect. These results are discussed in terms of previous research in this area, heterogeneity observed in Bipolar Disorder, implications for diagnostic classification, and the notion of Bipolar subtypes.","abstract_html":"The present research investigates the cognitive and perceptual mechanisms involved in mania-proneness.
