| 内容記述 | The present experiment examined the dissociation between the strength of a one-way avoidance response (AR) and one index of fear of the avoidance CS by using flooding procedures. Avoidance response strength was indexed by resistance to extinction of the AR and fear of the CS was assessed by a passive avoidance test. Rats were assigned to a non-shocked control group (C) and four experimental groups. The experimental groups, consisting of a time control (TC) and three flooding (FR, SR, DC) groups, were trained to avoid shock by running from shock room to safety room. After attaining the acquisition criterion, the four groups were given different treatments. Group TC was detained in the restraining box for 5 minutes without CS and US. Group FR received flooding for 5 minutes in the shock room, Group SR received 5 minutes of flooding in the safety room and Group DC was exposed to CS for 5 minutes in the restraining box. Following these treatments, all groups received Pavlovian extinction, then the subjects were deprived of food for 24 hours and given an independent test for measurement of fear. Flooding had no significant effect on hastening extinction of the AR, except for Group FR, which showed relatively rapid extinction of the AR. The experimental groups, however, showed reliably great residual fear with no differences among them. These results suggest that continuous CS exposure alone is not able to facilitate the extinction of the AR, and that the extinction of instrumental avoidance responses is dissociated from the reduction of fear. | |||||
