Abstract
While studying appetitive and aversive conditioning is common in psychopathology research, studies that measure both types of learning simultaneously are rare. To gain insight into the role of appetitive and aversive learning in the complex interaction of positive mood, negative mood, worry, craving, avoidance and impulsive behavior, this study used a relative measure of the strength of appetitive versus aversive learning – the learning asymmetry – as a predictor of network dynamics of mood states and behavior. 100 healthy volunteers performed an appetitive and aversive conditioning task and completed an ecological momentary assessment study, where they were surveyed six times per day for 21 days. Groups were defined based on higher sensitivity to appetitive learning (positive learning asymmetry) or aversive learning (negative learning asymmetry). The positive asymmetry group was hypothesized to be more sensitive to positive mood changes, and the negative asymmetry group was hypothesized to be more sensitive to negative mood changes. Contrary to our hypothesis, results show that impulsive behavior was more likely to follow negative mood, specifically anger, in the positive but not the negative asymmetry group. These results demonstrate the potential for network analysis to elucidate complex interactions between mood and behavior associated with individual differences in learning.
