The behavioral inhibition system and the verbal information pathway to children's fears

The behavioral inhibition system (BIS) is the neurological substrate of trait anxiety and is linked to the development of anxiety disorders. Three experiments are reported that investigate the moderating influence of the BIS on 1 pathway to fear: threat information. In all studies, children were given verbal information about a set of novel animals, and their BIS sensitivity was measured. The results suggest that BIS sensitivity (a) facilitates attentional biases to stimuli associated with threat information and (b) facilitates behavioral avoidance of novel stimuli associated with threat information. This suggests a possible mechanism through which the BIS may promote the acquisition of animal fears.
