We assessed whether novel praise statements could be used to (a) maintain and increase responses with existing reinforcement histories and (b) teach a previously untaught response among children diagnosed with autism spectrum disorder across two experiments. During response-stimulus pairing, two responses resulted in preferred edibles but only one…

Initial experiment demonstrated operant acquisition of an instrumental hand-pulling response in 4-8-month-old infants; the effect achieved with contingent, noncontingent, delayed reinforcement, and the suppression, recovery, and facilitation effects of noncontingent stimulation are discussed.

Study was designed to investigate the effects of signalled non-contingent reward on the operant behaviour of human subjects. (Authors)

The present study attempted to duplicate earlier findings and to investigate the effects of mechanical as well as personal reinforcement. However, the acquisition and extinction differences between oral and anal scoring types reported in the earlier studies were not obtained with either personal or mechanical reinforcement. (Author)

Article reviews evidence on the effects of contrast and matching, that these effects are related, and that both effects are reactions to the same independent variable. (Author/RK)

The major concern of the study was to determine what differences, if any, in independent reading-work behaviors were observed between baseline and experimental conditions using the Rules, Ignore, Praise technique with two seven year old children. During the reinforcement period children worked harder. Bibliography. (Author/AF)

The present experiments investigated the effects of several classical conditioning manipulations on the performance of young children in an instrumental discrimination learning situation. Two predictions from general conditioning-extinction theory were tested: (1) acquisition of an instrumental response to a stimulus for a positive reinforcer in a…

Assesses a self-reward contracting procedure intended to facilitate completion of self-administered desensitization. Self-referred snake phobics received either (a) self-administered desensitization; (b) self-administered desensitization with self-reward contracting; or (c) a self-administered placebo with self-reward contracting. Results show the…

This study asked whether the concurrent reinforcement of behavioral variability facilitates learning to emit a difficult target response. Sixty students repeatedly pressed sequences of keys, with an originally infrequently occurring target sequence consistently being followed by positive feedback. Three conditions differed in the feedback given to…

Three-month-old infants learned to activate a crib mobile by means of operant footkicks. Retention of the conditioned response was assessed in the presence of the nonmoving mobile. Although forgetting is typically complete after an 8-day retention interval, infants who received a reactivation treatment, a brief exposure to the reinforcer 24 hours…

Experimental modification of destructive and assaultive sibling interaction was carried out within the home environment. Two brothers (6 and 3 years old) were treated through token positive reinforcement techniques in an effort to improve their behavior towards each other. A "time out" from reinforcement procedures involved an isolation period for…

This conference report consists of two presented papers and a selected bibliography. The paper by Joan Gussow, "Behavioral Management and Educational Goals," is concerned with operant conditioning as a theory of learning and an instructional method. Basing their methods on the work of B.F. Skinner, educators who are proponents of this…

Seven 18- to 32-month-old children received from seven to 26 experimental sessions each between October 1966 and April 1967. A session lasted from 5 to 15 minutes and concerned control over the verbal responses of the children with token-operated reinforcement devices. In order to make the results of the experimental sessions meaningful, an…
