Resurgence is the recurrence of target behavior (e.g., challenging behavior) during a worsening of reinforcement conditions (e.g., increases in response effort, decreases in alternative reinforcement). Previous studies have examined the prevalence and magnitude of resurgence during functional communication training implemented with discriminative…

Of the diagnostic features of autism, relatively little research has been devoted to restricted and repetitive behavior, particularly topographically complex forms of restricted and repetitive behavior such as rigidity in routines or compulsive-like behavior (e.g., arranging objects in patterns or rows). Like vocal or motor stereotypy,…

Stereotypical behavior maintained by automatic reinforcement often does not result in harm but may be undesirable in some situations. In the current investigation, participants were 2 individuals who engaged in nonharmful stereotypical responses shown in an analogue functional analysis to be insensitive to social contingencies. After bringing…

Although previous research indicates that certain types of attention (i.e., statements related to behavior, tickles) may be differentially reinforcing, only one or two forms of attention are typically provided contingent on problem behavior during the attention condition in experimental functional analyses. In the present investigation, various…

A sequence of behaviors consisting of appropriate responses, inappropriate responses, or a combination of both can be linked together in a behavior chain. Several operant processes may disrupt behavior chains. For example, one or more members of the behavior chain may be affected when reinforcement is withheld for the last response in the chain…

In response to a previous article proposing perceptual reinforcement of stereotyped movements in autistic and mentally retarded persons, it is argued that this theory fails to take into account biological findings and theory regarding pathological stereotyped acts. An alternative theory derived from neurological concepts is suggested. (Author/DB)

The authors respond to criticism of their paper proposing a perceptual reinforcement of stereotyped movements in autistic and mentally retarded persons. The alternative theory based on neurobiological factors is judged to be insufficiently detailed and inadequate in scope. (Author/DB)

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…

We manipulated two parameters of response blocking to reduce pica: (a) the criteria for initiating the procedure (either earlier or later in the response chain) and (b) the distance from which the procedure was initiated. Results suggested that response blocking may be effective only when implemented early in the chain and with near-perfect…

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)

Experiments examined the effect of work requirements in combination with reinforcement schedules on the choice behavior of six adults with mental retardation and seven typical preschoolers. Results showed that participants' responding was largely controlled by the reinforcement received for responding to each level of work. (Author/CR)

Discusses behavioral momentum and the general behavioral relation between the persistence of behavior and the rate of reinforcement obtained in a given situation. Strategies for establishing the generality of behavioral relations are reviewed, followed by a brief summary of evidence for the generality of behavioral momentum. (Author/CR)
