Abstract
The Pavlovian conditioning model has been proposed as a model of etiology of anxiety disorders. However, it has been pointed out that traditional Pavlovian conditioning model could not explain some of clinical issues, then clinical researchers cast doubts on validities as a model of anxiety disorders. In recent years, it was proposed a cognitive Pavlovian conditioning model to reconcile the model with clinical findings. This model has been assumed that an elicitation of conditioned response (CR) is determined by two cognitive evaluations, which are dealt with the expectancy process and the revaluation process for the unconditioned stimulus (UCS). Results of experimental and clinical researches indicated that this model could explain many clinical phenomena. This model, however, is not enough to examine the effect of biological factors and evaluative conditioning on a fear learning as a phobic model. Therefore, we have proposed a new cognitive Pavlovian conditioning model in consideration of the effect of affective-evaluative processing to conditioned stimulus (CS). This model has been able to explain both the effect of an evaluative and a signal learning.
