SIMPLIFIED HABIT REVERSAL TREATMENT FOR CHRONIC HAIR PULLING IN THREE ADOLESCENTS: A CLINICAL REPLICATION WITH DIRECT OBSERVATION

Three developmentally normal adolescents with chronic hair pulling were treated with a simplified habit reversal procedure consisting of awareness training, competing response training, and social support. Treatment resulted in an immediate reduction to near-zero levels of hair pulling, with one to three booster sessions required to maintain these levels. The results were maintained from 18 to 27 weeks posttreatment, although 1 participant reported difficulty at follow-up. The effectiveness of simplified habit reversal and suggestions for future research are discussed.     

Self‐restraint and self‐injury: a demonstration of separate functions and response classes

We evaluated the self‐injurious behavior (SIB) and self‐restraint (SR) of an 11‐year‐old boy with severe mental retardation that were suspected to be functionally unrelated. A functional analysis (consequences provided for SIB) resulted in near‐zero levels of SIB across experimental conditions and did not indicate a specific function of SIB. In contrast, high, undifferentiated levels of SR were observed during the attention, control, alone, and demand conditions. Further analysis of a possible tangible function of SIB using pairwise comparisons resulted in a high rate of SIB during the contingent tangible condition, no SIB in the noncontingent tangible condition, and comparable levels of SR in both conditions. A subsequent analysis using restraint blocking during play and no‐play contexts suggested that SR produced automatic reinforcement under conditions of low ambient stimulation. Thus, SIB and SR were shown to be functionally independent and maintained by distinct consequences. The results are briefly discussed and suggestions for future research are provided.

A simple intervention for stereotypical engagement with an augmentative alternative communicative device

Although electronic devices may enhance the effectiveness of some behavioral interventions for children with autism spectrum disorders, such devices may also give rise to problem behavior such as repetitious button pressing (i.e., object stereotypy). Results of this study showed that a child with autism spectrum disorder only displayed high levels of object stereotypy on an iPad? when presses generated auditory output. Subsequently, results showed that when the participant used the iPad? without auditory output, his stereotypical behavior decreased and his manding for various items simultaneously increased.     

Introduction to the special issue on the intersection of professional selling and service

As organizational operations continue to evolve in response to increasing customer demands, frontline research has begun to consider how traditionally separate organizational functions may be complementary to firm performance. Specifically, as sales and service activities become increasingly intertwined within the frontline role, this special issue explores how the sales and service functions interact within an organization. The articles contained in this special issue consider the interaction of sales and service with respect to customer, employee, and firm outcomes. After introducing evolving thought in the area, we provide an overview of five articles that make up this special issue. We conclude by offering additional areas of research.     

Some effects of audio and visual stimulation on multiple forms of stereotypy

Three experiments were conducted to evaluate the effects of audio and visual stimulation, alone or in combination, on the behavior of three children who displayed multiple forms of stereotypy (e.g., hand mouthing, body rocking). The results of experiment 1 showed that all three participants displayed different forms of stereotypy when audio and visual stimulation were provided versus when no stimulation was provided. The results of experiments 2 and 3 showed that the form of one participant's stereotypy, but not the other two, changed when visual stimulation and audio stimulation were presented separately. Overall, the results suggest that ambient stimulation may influence both the form of and time allocation to stereotypy. Copyright © 2005 John Wiley & Sons, Ltd.     

The use of response cost to treat spitting by a child with autism

We evaluated the extent to which noncontingent access to one or multiple items and the contingent removal of a specific item decreased a young boy's spitting. Results indicated that the boy's spitting did not decrease when he was given noncontingent access to multiple, alternative stimuli or to a toy radio. By contrast, when the toy radio was removed contingent on spitting, the rate of the boy's spitting decreased to zero or near‐zero levels. Similar results were produced in the boy's special education classroom. Follow‐up sessions conducted 2 and 4 months later indicated that the reduction in the boy's spitting persisted across time.

Evaluation of the immediate and subsequent effects of response interruption and redirection on vocal stereotypy

We evaluated 2 3-component multiple-schedule sequences-a response interruption and redirection (RIRD) treatment sequence and a no-interaction control sequence-using a multielement design. With this design, we were able to evaluate the immediate and subsequent effects of RIRD on 2 participants' vocal stereotypy. For both participants, RIRD produced an immediate decrease in vocal stereotypy and did not result in a subsequent increase.
