DIFFERENTIAL REINFORCEMENT OF ALTERNATIVE BEHAVIOR AND DEMAND FADING IN THE TREATMENT OF ESCAPE-MAINTAINED DESTRUCTIVE BEHAVIOR

The escape-maintained destructive behavior of a boy with autism was reduced during instructional sequences with differential reinforcement of compliance (DRA), escape extinction without physical guidance, and demand fading. The procedure decreased destructive behaviors to near-zero levels and greatly increased compliance.     

Analysis of establishing operations for self-injury maintained by escape

Self-injurious behavior (SIB) can be maintained through negative reinforcement when, in the context of training or task requirements, it produces escape as a consequence. Several studies have demonstrated methods for identifying and treating SIB maintained by negative reinforcement; however, few analyses of the establishing operations associated with demand situations have been conducted. The current series of studies illustrates a method for identifying some establishing operations for escape by systematically altering certain dimensions of the demand context while maintaining an escape contingency for SIB. Dimensions assessed in these studies included task novelty, duration of instructional sessions, and rate of task presentation. Data indicate that these variables can have establishing properties for behavior maintained by escape. Implications of the results are discussed, as are potential refinements and extensions of the assessment procedures.     

MOMENTUM VERSUS EXTINCTION EFFECTS IN THE TREATMENT OF SELF-INJURIOUS ESCAPE BEHAVIOR

An individual's self-injurious escape behavior was treated using a high-probability instructional sequence with and without extinction. When presented alone, the high-probability sequence did not reduce self-injurious behavior. When escape extinction was implemented either alone or in combination with the high-probability sequence, self-injury decreased and compliance increased, suggesting that extinction may be a necessary component of the treatment for behavior problems maintained by escape.     

A COMPARISON OF SENSORY INTEGRATIVE AND BEHAVIORAL THERAPIES AS TREATMENT FOR PEDIATRIC FEEDING DISORDERS

We compared the effects of escape extinction (EE) plus noncontingent reinforcement (NCR) with sensory integration therapy as treatment for the feeding problems of 2 children. Results indicated that EE plus NCR was more effective in increasing acceptance, decreasing inappropriate behavior, and increasing amount consumed relative to sensory integration for both children. The results are discussed in terms of the challenges of evaluating sensory‐integration‐based treatments, and the reasons why component analyses of multicomponent treatments like sensory integration are important.     

A COMPARISON OF DIFFERENTIAL REINFORCEMENT AND NONCONTINGENT REINFORCEMENT TO TREAT FOOD SELECTIVITY IN A CHILD WITH AUTISM

We compared differential reinforcement plus escape extinction to noncontingent reinforcement plus escape extinction to treat food selectivity exhibited by a young child with autism. The interventions were equally effective for increasing bite acceptance and decreasing problem behaviors. However, a social validity measure suggested that noncontingent reinforcement was preferred by the child's caregiver.     

直觉和分析在不同任务条件下的逃生决策效果

目的：探讨针对简单和复杂逃生任务时, 直觉和分析在不同判断依据条件下的逃生决策效果。方法：采用两个主实验和两个预备实验。实验一和实验二的被试人数分别为：85人和87人。两个主实验均采取2 (思维方式：直觉和分析) × 2 (判断依据：简单和复杂)组间实验设计。主要结果：(1)针对简单逃生任务, 直觉组和分析组在不同判断依据条件下的逃生决策效果差异不明显; (2)针对复杂逃生任务, 在简单判断依据条件下分析决策优于直觉决策; 在复杂判断依据条件下直觉决策优于分析决策。主要结论：直觉性和分析性逃生决策的效果主要与决策任务的复杂程度有关, 而与判断依据的复杂程度关系不大。     

Additive,Multi-Component Treatment of Emerging Refusal Topographies in a Pediatric Feeding Disorder

This case study describes inter-disciplinary treatment of chronic food refusal and tube dependency in a 2-year-old female with a pediatric feeding disorder. Evidence-based behavioral components—including escape extinction (EE), differential reinforcement of alterative mealtime behavior (DRA), and stimulus fading—were introduced sequentially as the focus of treatment shifted to address refusal topographies along the chain of behaviors associated with consumption. The assessment process, treatment planning and sequencing, and generalization of treatment gains to caregivers are presented in detail. In doing so, the study illustrates the core features involved in applying a flexible, evidenced-based approach to treat severe feeding difficulties.     

The cognitive specificity of learned helplessness and depression deficits: The role of self-focused cognitions

Abstract

Four experiments assessed similarities and differences in learned helplessness and depression-related deficits in cognitive performance and self-focused cognitions. Subjects answered the Beck Depression Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh, 1961), were exposed to no-feedback or failure in unsolvable problems, and their response time in a digit comparison task (with or without a memory component, with different number of digits, and different number of mental transformations) and self-focused cognitions were assessed. Learned helplessness and depression deficits were found in a memory task, and the deficits increased with the number of digits. Depression deficits also increased with the number of transformations, and were also found in the no-memory/two transformation condition. Finally, task-related worries were related to learned helplessness deficits, and task-irrelevant thoughts were related to depression deficits. Findings were discussed in terms of the cognitive specificity of learned helplessness and depression deficits.     

Some effects of noncontingent positive reinforcement on multiply controlled problem behavior and compliance in a demand context

Functional analysis suggested that the problem behavior of an 8-year-old girl with autism was maintained by escape from demands and access to edible items. Noncontingent delivery of an edible item was sufficient to increase compliance and reduce the rate of problem behavior without the use of escape extinction in a demand context. Leaner and richer schedules of noncontingent reinforcement were equally effective, and there were minimal differences between noncontingent reinforcement and differential reinforcement of compliance.     

Providing an escape option reduces retaliatory aggression

The purpose of this study was to examine whether providing an explicit means to escape future attacks by a provocative fictitious participant reduces retaliatory aggression. Using a laboratory measure of aggression (the Point Subtraction Aggression Paradigm), 25 participants were given the opportunity to earn points with monetary value on a fixed ratio (FR) 100 schedule, and to subtract points from a fictitious participant on an FR 10 schedule. Aggressive responding was defined as the number of point subtraction responses by the participant. Aggressive responding also produced intervals free from further attack by the fictitious participant. Provocation was manipulated by having the fictitious person subtract points from the participant. Each participant next completed the same task with an explicit FR 10 escape response option added. The escape option produced intervals free from attack identical to the aggressive option, but without taking points away from the fictitious participant. Results indicate that the availability of an escape response attenuated aggressive behavior in response to provocation. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.
