Since the proposal of Tolman (1948) that mammals form maplike representations of familiar environments, cognitive map theory has been at the core of debates on the fundamental mechanisms of animal learning and memory. Traditional formulations of cognitive map theory emphasize relations between landmarks and between landmarks and goal locations as…

Results of this study indicate that sample group of unskilled laborers were more productive working under a schedule of continuous reinforcement than under a varied schedule, despite higher average earnings during the latter program. (RW)

A sequential training procedure combining operant and cumulative learning hierarchy principles was found effective in reducing the decrement in concept identification performance typically observed in older adults. (JMB)

Described is a program to provide educational services for severely emotionally disturbed (autistic or childhood schizophrenic) children based on behavior modification principles. Both formal and informal tests of performance are given in the areas of preacademic and readiness tasks. Each child is individually tutored in language, pre-reading,…

Two experiments examined whether associating an imitation task with an operant task affected 6-month-olds' memory for either task. Results indicated that infants successfully imitated a puppet's action for up to 2 weeks only if the associated operant task (pressing a lever to activate a miniature train) was retrieved first. Follow-up study…

Three experiments examined the memory-preserving effects of reactivation and reinstatement reminders following 6-month-olds' learning and forgetting of an operant task. Findings indicated that a single reactivation reminder extended infants' memory of an operant mobile task for 2 weeks, a single reinstatement extended it for 4 weeks. A single…

The effects of covert operant reinforcement upon remedial reading learning tasks were investigated. Forty junior high school students were taught to imagine either neutral scenes (control) or positive scenes (treatment) upon cue while reading. It was hypothesized that positive covert reinforcement would enhance performance on several measures of…

Projects a greater degree of success in developing management abilities in trainees by modifying and controlling human behavior. (EK)
