Primary Reactions

In Experiment I rats were trained preoperatively on a successive, free-operant discrimination with fixed component durations until S— responding had been minimized. Septal damage resulted in a transitory loss of discriminative performance due to an elevation of S— responding. Experiment II showed a comparable septal deficit following training which employed a “correction” procedure that penalized S— responding. It is concluded that, even after extended training, the maintenance of a low level of S— responding by rats in these types of discriminations requires the operation of an active mechanism which can be disrupted by septal damage. The possibility that this disruption results from a lesion-induced change either in the primary reactions to frustrative non-reward or in associated processes is discussed.

Response Task

Variable success in audiometric assessment of young children with operant conditioning indicates the need for systematic examination of commonly employed techniques. The current study investigated response and reinforcement features of two operant discrimination paradigms with normal I7-month-old children. Findings indicated more responses prior to the onset of habituation when the response task was based on complex central processing skills (localization and coordination of auditory/visual space) versus simple detection. Use of animation in toy reinforcers resulted in more than a twofold increase in the number of subject responses. Results showed no significant difference in response conditioning rate or consistency for the response tasks and forms of reinforcement examined.
