Conditioned emotional response in the rat: I. Constitution and situational determinants.

Abstract

48 rats selectively bred for high and low emotionality were employed in this study. Fear conditioning (as measured by the CER suppression technique) is significantly increased by greater emotional reactivity, by stronger shock intensity, and females are more susceptible to it than males. Backward and forward conditioning procedures were equally effective in establishing fear conditioning. Many complex interactions among these variables are reported. From Psyc Abstracts 36:02:2EI74S.
