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…

Examines the relationship between self-instructions and subsequent instruction-following performance of 7- and 8-year-old children as a function of previous reinforcement for rule-breaking or rule-following. (BD)

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…

This paper addresses some of the practical ways by which students can be given information about the adequacy of their responding. The author views this information as all that is frequently necessary to alter an inappropriate behavior. Thus, he considers feedback to be the first step in most behavior management programs. Studies to determine how…

The successful application of functional analysis to problem behavior suggests the need to examine: additional functional properties of behavior involving social avoidance, biological reinforcement, and respondent conditioning; the role of context (including social factors and biological factors); and the multidimensional character of assessment…

Functional assessment is redefining the standards for clinical interventions with problem behavior and reemphasizing the importance of basic behavioral mechanisms. It has shown the importance of complex patterns of behavioral control, functional assessment as an ongoing process, and the importance of attention to antecedent variables. Future…

The study evaluated the effectiveness of superimposition and subsequent removal of a schedule of continuous reinforcement (CRF) as a rate-decreasing procedure in efforts to eliminate unwanted behaviors. Examination of lever-pressing patterns of eight male rats showed responding was substantially reduced during the superimposition of CRF but…

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)

A covert self-instructional program was used to reduce the frequency of a hospitalized chronic schizophrenic's inappropriate verbalizations. A marked reduction in the frequency of the target behavior accompanied the treatment intervention, and improved verbal behavior was directly responsible for the decision to discharge the subject from the…

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…

Two studies measured the feasibility of DRO (differential reinforcement of other behavior) and VT (variable time) reinforcement in reducing body rocking stereotypy of institutionalized severely and profoundly retarded adults (N=2 and 5). (CL)
