An experiment with adult humans investigated the effects of response-contingent money loss (response-cost punishment) on monetary-reinforced responding. A yoked-control procedure was used to separate the effects on responding of the response-cost contingency from the effects of reduced reinforcement density. Eight adults pressed buttons for money…

Token reinforcement procedures and concepts are reviewed and discussed in relation to general principles of behavior. The paper is divided into four main parts. Part I reviews and discusses previous research on token systems in relation to common behavioral functions--reinforcement, temporal organization, antecedent stimulus functions, and…

This article reviews evidence from basic and translational research with pigeons and humans suggesting that the persistence of operant behavior depends on the contingency between stimuli and reinforcers, and considers some implications for clinical interventions. (Contains 4 figures.)

Recent mandates related to the implementation of evidence-based practices for individuals with autism spectrum disorder (ASD) require that autism professionals both understand and are able to implement practices based on the science of applied behavior analysis (ABA). The use of the term "applied behavior analysis" and its related concepts…

An observing procedure was used to investigate the effects of alterations in response-conditioned-reinforcer relations on observing. Pigeons responded to produce schedule-correlated stimuli paired with the availability of food or extinction. The contingency between observing responses and conditioned reinforcement was altered in three experiments.…

Evaluation of reductive treatment versus instructional treatments on the generalized reduction of problem behaviors in two adolescents with severe intellectual disabilities indicated that when only one member of a response class was blocked, a collateral increase in other problem behaviors was observed, but learning an alternative positive…

A review of the January 1993 issue of the "Journal of the Experimental Analysis of Behavior" concludes that behavioral interventions produce collateral effects, but predicting those effects in applied work is complicated because of verbal and instructional influences and because of interactions among reinforcer types.

Recent experiments are reviewed in three areas of research concerning reinforcement schedules: (1) behavioral history effects on schedule performance; (2) the role of instructions in schedule performance of humans; and (3) dynamic schedules of reinforcement. The paper concludes by identifying some general issues concerning reinforcement schedules…

Seven parents conducted assessments in an outpatient clinic using a prescribed hierarchy of antecedent and consequence treatment components for their children's problem behavior. Brief assessment of potential treatment components identified variables controlling children's appropriate behavior. Experimental control was achieved for six of the…

This commentary summarizes methodological and conceptual issues in functional analysis methodologies and offers some suggestions for their resolution. Considered are increasing complexity, absence of contingencies during assessment, use of subtle manipulations, alternative assessment strategies, analysis of antecedent influences on behavior,…

This study examined how 3 students (ages 14-18, with emotional or behavioral disorders) allocated their responding across 2 concurrently available tasks associated with unequal rates and equal versus unequal qualities of reinforcement. It found that time allocated to concurrent response alternatives was approximately proportional to obtained…

This study examined methods for determining how extinction should be applied to different functions of self-injurious behavior, specifically head-banging of three children with developmental disabilities. Since each subject's head-banging was maintained by different reinforcement contingencies, behavioral treatment techniques, although all based…

As in studies of self-control, a tit-for-tat contingency in an iterated prisoner's dilemma game creates a conflict between maximization of local and global reinforcement. The present experiments examine this conflict in a multiplayer prisoner's dilemma game. Versus tit for tat, cooperation corresponds to self-control; defection, always immediately…

With their origins in scientific validation, behavior-analytic applications have understandably been developed with an engineering rather than a crafting orientation. Nevertheless, traditions of craftsmanship can be instructive for devising aesthetically pleasing arrangements--arrangements that people will try, and having tried, will choose to…

Three adolescent students with special educational needs were given reinforcers (nickels) according to three different concurrent variable-interval schedules. Time allocated to the assigned tasks was in linear relationship to the reinforcement rate. However, changes in reinforcement schedules were not followed by changes in allocation patterns…
