Differentiation Matching in School Desegregation Workshops

The effectiveness of matching the conceptual structure of participants in educational training and psychotherapy experiences has been demonstrated in previous research. This paper describes an attempt to test the effectiveness of this model in a school desegregation workshop designed to promote a mandatory bussing proposal by a local school board. Differentiation matching had little effect on participants' global judgments of satisfaction with workshop goals but was significantly and inversely related to the decision to voluntarily bus a child, especially among blacks. Abstractness of topics discussed affected participant endorsement of workshop goals but did not affect bussing decision. The findings suggest that how such workshops are organized is dependent on whether the workshop success is to be evaluated on the basis of community public relations or actual decisions to bus children.     

Control of echolalic speech in psychotic children

Immediate echolalia, a common language disorder in psychotic children, was studied in a series of replicated single-subject designs across six schizophrenic and five normal children. In Experiment 1, each child was presented with several questions and commands, some of which set the occasion for specific, appropriate responses and some of which did not. The former were referred to as discriminative stimuli and the latter, as neutral stimuli. The psychotic children tended to echo the neutral stimuli while responding appropriately to the discriminative stimuli; the normal children, in contrast, typically echoed neither type of stimulus. In Experiment 2, three psychotic children were taught appropriate responses to each of several neutral stimuli. Following this training, the children generally responded appropriately to these stimuli without echoing. A plausible interpretation of these results is that the neutral stimuli were initially incomprehensible or meaningless to the children (whereas the discriminative stimuli were comprehensible or meaningful) and that verbal incomprehensibility may be one important determinant of immediate echolalia. Finally, the results are noteworthy in that they isolate a sufficient treatment variable (i.e., the reinforcement of alternative, nonecholalic responses) for eliminating instances of this language anomaly.     

Review of Spinal Muscular Atrophy (SMA) for Prenatal and Pediatric Genetic Counselors

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular condition with degeneration of the anterior horn cells in the spinal column. Five SMA subtypes exist with classification dependent upon the motor milestones achieved. Study of the SMN1 (survival motor neuron) and SMN2 genes as well as the concepts of the “2?+?0” carriers, gene conversion, de novo mutations and intragenic mutations allow for a better understanding of SMA. Detailing the carrier and diagnostic testing options further deepens the genetic counselor’s knowledge of SMA. A review of care guidelines and research options is included as this information gives a patient a well-rounded view of SMA. Although SMA is most commonly associated with the SMN1 gene, a number of spinal muscular atrophies not caused by genetic changes in this gene may be included as differential diagnoses until confirmatory testing can be completed. SMA is a complex condition requiring a detailed knowledge on the genetic counselor’s part in order to explain the disorder to the patient with clarity thus facilitating increased communication and decision making guidance with the patient.     

Evidence-based practice in family therapy and systemic consultationChild-focused problems

Evidence for the effectiveness of family therapy and family-based interventions from critical literature reviews and controlled trials is considered for families with children and adolescents who present with various difficulties. The evidence supports the effectiveness of family therapy as an effective treatment either alone or as part of a multimodal or multisystemic treatment programme for child abuse and neglect, conduct problems, emotional problems and psychosomatic problems. Implications for practice, training and continuing professional development in the field of family therapy are discussed.     

The Beavers, McMaster and Circumplex clinical rating scales: a study of their sensitivity, specificity and discriminant validity

To assess the sensitivity and specificity of clinical rating scales from the Beavers, McMaster and Circumplex models of family functioning videotapes of sixty families engaging in a standardized family task interview were rated using the three rating scales. The sixty families included twenty containing a child with an emotional disorder, twenty containing a child with a mixed disorder of emotions and conduct, and twenty in which none of the children presented with clinically significant difficulties. The three rating scales accurately classified 85-90% of normal controls, 70-90% of cases containing a child with a mixed disorder of emotions and conduct, and 55-65% of families containing a child with an emotional disorder. On the rating scales, the Beavers and McMaster models showed particularly high levels of sensitivity in detecting clinical cases, whereas the Circumplex rating scale was particularly good at classifying non-clinical cases accurately.     

Multiple‐stimulus preference assessments: a comparison of free‐operant and restricted‐operant formats

We compared free‐operant and restricted‐operant multiple‐stimulus preference assessments with three children diagnosed with mental retardation. The methods produced comparable results, although the free‐operant assessment identified fewer potential reinforcers than the restricted‐operant assessment. The highest‐ and lowest‐ranked stimuli from both methods were subsequently evaluated in a concurrent‐operants reinforcer assessment. All participants engaged in behavior that resulted in access to the highest‐ranked stimuli the majority of the time, thus validating both preference assessment methods as effective in identifying reinforcers.

Evaluation of satiation‐resistant head rocking

The persistent head rocking of a woman diagnosed with profound mental retardation was examined during three separate assessments. First, a functional analysis demonstrated that head rocking was maintained independent of social consequences. Next, an antecedent assessment revealed that exposure to alternative sources of stimulation reduced head rocking, but only when the stimulation was being provided. A third assessment, which consisted of an enriched environment, replicated the findings of the first two assessments. Across all three assessments, head rocking persisted at extremely high rates when alternative stimulation was unavailable and returned to high levels immediately following the removal of alternative sources of stimulation. An environmental enrichment (EE) intervention, which was based on the results of the functional analysis and antecedent assessment, resulted in a 70% reduction in the occurrence of the head rocking. In addition, a social validity assessment revealed that the participant's caregivers rated the EE intervention as both effective and socially acceptable. The particular challenges that satiation‐resistant aberrant behavior presents for behavior analysts are addressed. Specific suggestions for research on intervention strategies for persistent aberrant behavior are also provided. Copyright © 2000 John Wiley & Sons, Ltd.     

Interpreting functional analysis results using the real-time recording of independent and dependent variables

An extended series of functional analysis conditions were conducted to assess the operant function of aggressive behaviors emitted by a 33-year-old female with diagnoses of severe mental retardation and organic psychosis. Results from the primary test conditions were fairly undifferentiated, but response rates were elevated in the control condition. Independent-variable integrity data from the control condition indicated that aggressive behaviors were nearly always contiguous with the fixed-time delivery of experimenter attention. These results are discussed in the context of the current control condition functioning as a possible test for escape from social interaction. © 1998 John Wiley & Sons, Ltd.     

Assessing preferences of individuals with developmental disabilities using alternative stimulus modalities: A systematic review

The purpose of this systematic review was to identify investigations comparing the efficacy of alternative modality (e.g., pictorial, verbal, video) stimulus preference assessments for individuals with developmental disabilities. We identified articles by searching peer‐reviewed journals using the PsycINFO and ERIC databases, conducting table of contents searches of common behavioral outlets, and conducting ancestral searches of recent reviews and practitioner summaries of preference assessment methodology. A total of 32 articles met our inclusion criteria. These studies were then coded across a variety of features to gain a better understanding of the efficacy of alternative format preference assessments for individuals with developmental disabilities. In addition, we reviewed this literature for the use of prerequisite‐skill assessments and contingent‐reinforcer access to further investigate the relation between these variables and the accuracy of pictorial, verbal, and video preference assessments. A variety of methodological concerns are discussed as well as suggestions for future research.
