We investigated whether contextual fear conditioning could be related to the behavioral trait of locomotor reactivity to novelty in undisturbed and chronically stressed rats. Fear conditioning was found to be specifically enhanced in low reactive-stressed animals, as compared to low reactive-undisturbed rats. The results suggest that individuals that display low reactivity to novelty are more susceptible to be influenced by stress exposure to subsequently exhibit potentiated contextual fear conditioning.
