The loss of behavioral flexibility is common across a number of neuropsychiatric illnesses. This may be in part due to the loss of the ability to detect or use changes in action-outcome contingencies to guide behavior. There is growing evidence that the ventral hippocampus plays a critical role in the regulation of flexible behavior and…

In our everyday life, we often need to anticipate the potential occurrence of events and their consequences. In this context, the way we represent contingencies can determine our ability to adapt to the environment. However, it is not clear how agents encode and organize available knowledge about the future to react to possible states of the…

Findings from a randomized controlled design study of an ability-based versus needs-based approach to response-contingent learning among children with significant developmental delays and disabilities who did not use instrumental behavior to produce reinforcing consequences are reported. The ability-based intervention and needs-based intervention…

The present study investigated the effect of the presence of the experimenter on behavioral sensitivity to contingency change. In history training, college students were exposed to differential reinforcement of low rate (DRL) and fixed-ratio (FR) schedules, and in testing, to a fixed-interval (FI) schedule. For the control group, instructions were…

The authors examined the effects of randomized and delayed credit on the percentage of college students participating at four pre-defined levels on each class discussion day: non-participation, credit-level participation, frequent participation, and dominant participation. Although the same amount of participation credit was available to students…

Three punishment procedures--contingent applications of water mist, lemon juice, and vinegar--were evaluated as aversive treatment methods for a self-stimulatory behavior exhibited by a severely retarded 11-year-old male. The water mist procedure was as effective as lemon juice or vinegar, presented less physical threat to the client, and was…

Reward contingencies and other extrinsic constraints on behavior can lead to reduced levels of interest in and/or decreased engagement in a target activity in a subsequent noncontingent situation. It has been hypothesized that this effect is caused by a change in the self-perceived locus of motivation from intrinsic to extrinsic. It follows from…

Treatment approaches (a behavioral program including both contingency management instruction for parents and self-control training for children, or either drug therapy or contingency management, alone) were compared for effectiveness in dealing with eight hyperactive children (7-10 years old). A self-control curriculum composed of self-direction,…

College students were instigated by a confederate and then interacted with that same person on a reaction time completion task. The confederate informed half of the treatment subjects of the response strategy he intended to adopt. The other half received an irrelevant message. Subjects in both message conditions then competed against the…

Findings from two studies of 42 children with profound developmental delays (26 males and 15 females) using systematic and intense response-contingent learning opportunities interventions are reported. Response-contingent learning games were used to promote the participants' use of behavior that either produced environmental consequences or…

The role of sensory reinforcement was examined in programing multiple treatment gains in self-stimulation and spontaneous play for four developmentally disabled children (eight to ten years old). (Author/SBH)

Assessed main and collateral effects of the assessment and treatment of attention-maintained self-injury, with regard to four categories of behavior: self-injury, a novel mand, pre-existing prosocial responses, and other aberrant responses. Results suggest that self-injury, prosocial responses, and other abberant behaviors are within the same…

The effects of different schedules of noncontingent reward on subsequent learning in children were investigated. In the first phase of the experiment subjects performed a block-design matching task and received one of three schedules of noncontingent reward, i.e., continuous reward (Group CRF), random reward on 50% of the trials (Group 50R), or no…

Describes an intervention program to help abused children learn to inhibit aggressive behavior and increase cooperative behavior. Sixteen physically abused children participated in the program. Behavior ratings were made during the program and in-home follow-ups. Following initial increases in aggressive behaviors, significant increases in…

In two studies undergraduates with low self-esteem followed reinforcement paradigms. Found overt events to be preferable as reinforcers, although no differences existed between reinforcement groups and both did better than controls. Also found desirable behaviors that occurred infrequently, and very frequent but neutral behaviors, to be the most…
