Avoidance problems reconsidered

Publication date: April 2019Source: Current Opinion in Behavioral Sciences, Volume 26Author(s): Christopher K Cain, Nathan S KlineActive avoidance is the prototypical paradigm for studying aversively motivated instrumental behavior. However, avoidance research stalled amid heated theoretical debates and the hypothesis that active avoidance is essentially Pavlovian flight. Here I reconsider key ‘avoidance problems’ and review neurobehavioral data collected with modern tools. Although the picture remains incomplete, these studies strongly suggest that avoidance has an instrumental component and is mediated by brain circuits that resemble appetitive instrumental actions more than Pavlovian fear reactions. Rapid progress may be possible if investigators consider important factors like safety signals, response-competition, goal-directed versus habitual control and threat imminence in avoidance study design. Since avoidance responses likely contribute to active coping, this research has important implications for understanding human resilience and disorders of control.
