The Effects Of Chlorpromazine On Escape And Avoidance Behavior, Susan E. Bohlmann Lapato Apr 1971

The Effects Of Chlorpromazine On Escape And Avoidance Behavior, Susan E. Bohlmann Lapato

Masters Theses

The present study was designed to investigate the effectiveness of a two lever escape avoidance paradigm as a potential drug evaluation procedure. In this procedure responses on one lever postponed the onset of shock for a fixed period of time while responses on the other lever were effective only in terminating shock. This procedure effectively separates the escape and avoidance behaviors of a single organism and should provide a sensitive baseline upon which to measure the specific effects of drugs upon these two behaviors. The specific and differential effects of three dose levels of chlorpromazine upon escape and avoidance behaviors …


The Effects Of Repetitive Stimulation On The Aggressive Behavior Of The Fighting Cock: A Test For Habituation, Howard E. Farris, Thomas W. Cey Jan 1971

The Effects Of Repetitive Stimulation On The Aggressive Behavior Of The Fighting Cock: A Test For Habituation, Howard E. Farris, Thomas W. Cey

Honors Theses

A fighting cock was repeatedly presented with its own mirror image. The rate of aggressive display and attack behavior elicited by the mirror rapidly decreased to zero. Subsequent exposure of the experimental subject to a live target bird was found to be sufficient to reinstate responding to the mirror. However, upon repeated exposure to the mirror image alone aggressive responding quickly decreased again to zero.
