- Title
- THE DISCRIMINATIVE PROPERTIES OF RESPONSE-CONTINGENT FEEDBACK IN THE MAINTENANCE OF SHUTTLE-BOX AVOIDANCE.
- Creator
- BURGHARDT, WALTER FRANCIS, JR., Florida Atlantic University, Scheuer, Cynthia
- Abstract/Description
-
Thirty-six rats were used to study the effects of manipulating both the density and response contingency of feedback during the extinction (OE) of discriminated shuttle-box avoidance. Three operant groups had the opportunity to receive response-produced feedback on either 100, 60, or 30 per cent of the extinction trials. Three yoked groups received the' same number and pattern of feedback stimuli as the operant groups, but independently of their own behavior. Significant ordering was obtained...
Show moreThirty-six rats were used to study the effects of manipulating both the density and response contingency of feedback during the extinction (OE) of discriminated shuttle-box avoidance. Three operant groups had the opportunity to receive response-produced feedback on either 100, 60, or 30 per cent of the extinction trials. Three yoked groups received the' same number and pattern of feedback stimuli as the operant groups, but independently of their own behavior. Significant ordering was obtained between all operant and all yoked groups, and between operant and yoked groups at all three feedback percentage levels. An ordering trend was obtained for the feedback percentage dimension, which was, however, not significant. The results, however, clearly supported the discrimination hypothesis and upheld the importance of response produced stimulus change in the maintenance of avoidance behavior.

- Title
- THE EFFECT OF AMPHETAMINE ON FREE OPERANT AVOIDANCE BEHAVIOR IN THE RAT.
- Creator
- MOLINA, ENRIQUE JUAN, Florida Atlantic University
- Abstract/Description
-
Parametric manipulation of Sidman avoidance produced different kinds of performances in subjects, which were tested while under amphetamine treatment. The results were found to be incompatible with the principles of the stimulus control theory of Weiss and Laties as well as other general and particular explanations of the drug's effect. An explanation was suggested in terms of general arousal and individual differences.

- Title
- THE RELATIVE EFFICIENCIES OF TWO PROCEDURES FOR THE EXTINCTION OF DISCRIMINATED AVOIDANCE CONDITIONING.
- Creator
- JACKSON, MASON CALVIN, JR., Florida Atlantic University, Otten, Cynthia S., Charles E. Schmidt College of Science, Department of Psychology
- Abstract/Description
-
Eighteen rats were used to study two procedures for the extinction of discriminated avoidance. One group (OE) was placed on extinction defined by presenting shocks as programmed but independently of the S's responses, while the other group (CE) was placed on classical extinction defined by the removal of all shocks. The two procedures were compared in terms of rate of decline and terminal level of extinction performance. In addition, the two groups were placed on a discrimination reversal...
Show moreEighteen rats were used to study two procedures for the extinction of discriminated avoidance. One group (OE) was placed on extinction defined by presenting shocks as programmed but independently of the S's responses, while the other group (CE) was placed on classical extinction defined by the removal of all shocks. The two procedures were compared in terms of rate of decline and terminal level of extinction performance. In addition, the two groups were placed on a discrimination reversal task in order to assess each procedure's effects on a new learning problem. The CE group reached a lower level of extinction performance in a fewer number of blocks than the OE Ss. Furthermore, the CE Ss were inferior to the OE Ss in terms of discrimination reversal performance as well. An interpretation of the results in terms of the removal and reinstatement of cues was offered although an alternative explanation relating to a change in the motivational states of the two groups during extinction was also presented. The interpretation in terms of the presence or absence of cues seemed to account for more of the present findings than the traditional one advocating changes in motivational levels resulting from the two divergent extinction operations.

- Title
- HEART RATE RESPONSE AND SUPPRESSION OF BAR PRESSING DURING CER AND PASSIVE AVOIDANCE.
- Creator
- SEGER, KARL ALFRED, III., Florida Atlantic University
- Abstract/Description
-
According to the cardiac-somatic hypothesis, heart rate changes are a function of changes in somatic activity. Conversely, the Independent Response Theory states that conditioning of heart rate and somatic activities are independent of each other. Using two groups, the present study examined these conflicting theories by measuring changes in heart rate and bar press suppression during 10 days of CER and passive avoidance conditioning. Results of this study indicate that heart rate responses...

Conversely, the Independent Response Theory states that conditioning of heart rate and somatic activities are independent of each other. Using two groups, the present study examined these conflicting theories by measuring changes in heart rate and bar press suppression during 10 days of CER and passive avoidance conditioning. Results of this study indicate that heart rate responses and bar press suppression conditioned independently of each other, during both CS and post CS periods. Further, while bar pressing suppressed rapidly in both groups, heart rate responses were different between the two groups suggesting that although both procedures conditioned the same behavioral results, they elicit different autonomic responses.

- Title
- THE RELATIVE DISCRIMINATIVE ROLE OF SHOCK AND RESPONSE CONTINGENT FEEDBACK ON THE MAINTENANCE OF TWO WAY AVOIDANCE.
- Creator
- SCHONFELD, LAWRENCE IRA., Florida Atlantic University
- Abstract/Description
-
Twenty-four rats were trained to avoid shock in a shuttlebox, receiving feedback for a correct response. During extinction, matched pairs were tested under response contingent or response independent feedback, with either shock or no shock. The combination of response contingent feedback and no shock led to the greatest resistance to extinction. No other significant differences were found. The results were used to support the discrimination hypothesis, and concurred with other studies with...

During extinction, matched pairs were tested under response contingent or response independent feedback, with either shock or no shock. The combination of response contingent feedback and no shock led to the greatest resistance to extinction. No other significant differences were found. The results were used to support the discrimination hypothesis, and concurred with other studies with regard to: (1) the functional similarity of feedback and CS termination in the acquisition and maintenance of avoidance, and (2) the importance of the interaction of the response contingency with the avoidance contingency, in determining the effects on avoidance responding.
