Rabbit eyelid conditioning as a function of unconditioned stimulus duration.

Abstract

Reports eyelid conditioning data for 85 male New Zealand white rabbits, employing UCS durations of 50, 100, and 200 msec. Ss with a 50-sec UCS were slower to start conditioning than the 100- or 200-msec groups. The 200-msec group reached a lower terminal performance level than the other 2 groups. Results are related to drive-reduction theory and to possible technical difficulties in the presentation of the cheek-shock UCS. (17 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
