Reward responsiveness (BAS) facilitates contingency awareness in appetitive conditioning.
Individual differences in reinforcement sensitivity may shape associative learning processes. We investigated how behavioral inhibition and activation systems (BIS/BAS), that is, variation in avoidance versus approach tendencies, modulate awareness of stimulus-outcome contingencies during appetitive conditioning (with monetary rewards) and aversive conditioning (with electric shocks) in N = 62 uninstructed participants (54 women). BAS "reward responsiveness" was found to predict subjective expectancy of appetitive (but not aversive) outcomes, independent of extraversion and neuroticism. BIS was unrelated to contingency awareness. Results highlight reward sensitivity as a distinct trait, facilitating conscious detection and processing of reward contingencies.
期刊介绍：
The neurobiology of learning and memory is entering a new interdisciplinary era. Advances in neuropsychology have identified regions of brain tissue that are critical for certain types of function. Electrophysiological techniques have revealed behavioral correlates of neuronal activity. Studies of synaptic plasticity suggest that some mechanisms of memory formation may resemble those of neural development. And molecular approaches have identified genes with patterns of expression that influence behavior. It is clear that future progress depends on interdisciplinary investigations. The current literature of learning and memory is large but fragmented. Until now, there has been no single journal devoted to this area of study and no dominant journal that demands attention by serious workers in the area, regardless of specialty. Learning & Memory provides a forum for these investigations in the form of research papers and review articles.
