Abstract

“With a 2X2 factorial design employing 32 hooded rats in shuttlebox avoidance training, prompt and delayed response termination both of CS and of US were studied on escape trials only. The Ss of all groups were treated identically on avoidance trials. Prompt termination both of CS and of US by the escape response had, independently, facilitating effects on the frequency of anticipatory avoidances. The latency of the escape response, however, was facilitated solely by US termination. The interpretations of the emergence of anticipatory responding which stress only response termination of the US are not adequate to explain the data.” From Psyc Abstracts 36:01:1EK02K.
