Latency of the eyelid UCR during conditioning

Changes in UCR latency during eyelid conditioning were investigated on 24 Ss in an orthogonal design involving two levels of CS intensity and CS-UCS interval and three levels of conditioning. Significant decreases in UCR latency over the acquisition trials were found. These were related to level of conditioning such that the good conditioners showed a significantly more rapid decrease. Further, the amount of decrease prior to the first CR significantly predicted the level of conditioning. These findings were entirely supported in a further replication.

Further evidence for intrassession decrements in eyelid conditioning.

4 groups of 20 Ss were given 100 classical eyelid conditioning trials on each of five days. The groups formed a 2 × 2 design with CS Intensity and Room Illumination as the factors involved. Results showed: (1) an increase in CRs over days with more rapid conditioning in the dimmer room; (2) consistent decreases in CRs within sessions, more apparent with the dimmer CS; (3) consistent decreases in latency over trials within a session; and (4) over-all higher performance with the brighter CS.

CS directionality and intensity in avoidance learning and extinction

Rats were given avoidance conditioning and extinction in a shuttlebox with simple and complex directional cue stimuli. The hypotheses were: increasingly complex cue stimuli would produce faster learning and slower extinction; and avoidance from CS source would produce faster learning and slower extinction. Results were analyzed by 2-way analysis of variance. All hypotheses were supported at p<.01. The results were interpreted in terms of Mowrer’s (1960) fear-reduction theory and a drive-stimulus-reduction model.
