RESUMEN

Children and adolescents, relative to adults, disproportionately favor smaller, immediate outcomes over larger, delayed outcomes. From a behavioral perspective, this sensitivity toward immediate rewards constitutes impulsive choice, which characterizes numerous behavioral health problems commonly observed during childhood (particularly among individuals with neurobehavioral disabilities). Accordingly, a variety of behavioral technologies have been developed and are widely implemented in applied settings (e.g., self-monitoring programs, interdependent group contingencies, individualized token reinforcement programs) to reduce impulsive responding and promote self-control. Although there is a plethora of research literature detailing these interventions, several promising delay fading procedures may also have clinical utility in applied treatment contexts. The purpose of the present review is to highlight contemporary behavior-analytic research involving delay fading procedures that may increase self-control among children and adolescents and facilitate additional research in the area of self-control.

RESUMEN

Delay discounting describes the tendency to devalue delayed consequences or future prospects. The degree to which an individual discounts delayed events appears trait-like in that it is stable over time and across functionally similar situations. Steeply discounting delayed rewards is correlated with most substance-use disorders, the severity of these disorders, rates of relapse to drug use, and a host of other maladaptive decisions impacting human health. Longitudinal data suggest steep delay discounting and high levels of impulsive choice are predictive of subsequent drug taking, which suggests (though does not establish) that reducing delay discounting could have a preventive health-promoting effect. Experimental manipulations that produce momentary or long-lasting reductions in delay discounting or impulsive choice are reviewed, and behavioral mechanisms that may underlie these effects are discussed. Shortcomings of each manipulation technique are discussed and areas for future research are identified. While much work remains, it is clear that impulsive decision-making can be reduced, despite its otherwise trait-like qualities. Such findings invite technique refinement, translational research, and hope.

RESUMEN

The current study is a systematic replication and extension of work by Schweitzer & Sulzer-Azaroff (1988). The effects of delay fading alone and in combination with signals on choices between larger, delayed reinforcers and smaller, immediate reinforcers by four children with language deficits were examined. For one of the two children exposed to delay fading alone, larger reinforcers were selected at longer delays relative to the initial self-control assessment. For all four children, the delay-fading-plus-signal condition resulted in selection of larger reinforcers at considerably longer delays relative to the self-control assessment.

RESUMEN

Nearly half of children with autism have eloped from their caregivers. In assessing elopement, the initial functional analytic results of this case study found positive reinforcement in the form of attention and access to tangibles were the maintaining variables. Functional communication training (FCT) in combination with delay fading was utilized to increase communication and decrease elopement. Results indicated that communication was consistent, elopement remained low, and the child learned to wait.

RESUMEN

The earliest stages of functional communication training (FCT) involve providing immediate and continuous reinforcement for a communicative response (FCR) that is functionally equivalent to the targeted problem behavior. However, maintaining immediate reinforcement is not practical, and the introduction of delays is associated with increased problem behavior. The present study evaluated the effects of providing alternative reinforcers during delays to reinforcement with a 13-year-old boy with an intellectual disability. Problem behavior was less likely when alternative reinforcers were available during delays.

RESUMEN

Signals during delays to reinforcement may lessen reductions in responding that typically occur when there is a delay between a response and its reinforcer. Sparse applied research has been devoted to understanding the conditions under which responding may be maintained when delays to reinforcement are introduced. We evaluated the extent to which providing signals during delay fading affected responding in the context of differential reinforcement of communication responses. Three individuals were exposed to gradually increasing signaled and unsignaled reinforcement delays in multiple-schedule and/or withdrawal designs. Results for 2 of 3 participants suggested that (a) the presence of signals facilitated response maintenance under delayed reinforcement and (b) coordinated basic and applied research may advance both conceptual understanding and clinical outcomes of delayed reinforcement.
