Abstract

Conducted 3 experiments in which a total of 179 female Sprague-Dawley rats ingested a novel solution. Ss which were then anesthetized for a CS-UCS interval of approximately 9 hr. and poisoned on recovery from anesthetic showed a clear aversion to the novel solution. The same CS-UCS interval did not support any measureable aversion when Ss were awake in the interval. It is suggested that the CS-UCS interval might be extended indefinitely with this technique. Results are not consistent with a simple decay model and are quite compatible with interference or learned safety models of conditioning. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
