EFFECTS OF WITHIN-STIMULUS AND EXTRA-STIMULUS PROMPTING ON DISCRIMINATION LEARNING IN AUTISTIC CHILDREN1

Two different prompting procedures to teach visual and auditory discriminations to autistic children were compared. The first involved presenting an added cue as an extra-stimulus prompt. This required the child to respond to both prompt and training stimulus. The second involved the use of a within-stimulus prompt. This consisted of an exaggeration of the relevant component of the training stimulus and thus did not require that the child respond to multiple cues. The results indicated that (1) children usually failed to learn the discriminations without a prompt, (2) children always failed to learn when the extra-stimulus prompt was employed but usually did learn with the withinstimulus prompt, and (3) these findings were independent of which modality (auditory or visual) was required for the discrimination.     

Concurrent second-order schedules of reinforcement

Responses on one key (the main key) of a two-key chamber produced food according to a second-order variable-interval schedule with fixed-interval schedule components. A response on a second key (the changeover key) alternated colors on the main key and provided a second independent second-order variable-interval schedule with fixed-interval components. The fixed-interval component on one variable-interval schedule was held constant at 8 sec, while the fixed interval on the other variable-interval schedule was varied from 0 to 32 sec. Under some conditions, a brief stimulus terminated each fixed interval and generated fixed-interval patterns; in other conditions, the brief stimulus was omitted. Relative response rate and relative time deviated substantially from scheduled relative reinforcement rate and, to a lesser extent, from obtained relative reinforcement rate under both brief-stimulus and no-stimulus conditions. Matching was observed with equal components on both schedules; with unequal components, increasingly greater proportions of time and responses than the matching relation would predict were spent on the variable-interval schedule containing the shorter component. Preference for the shorter fixed interval was typically more extreme under brief-stimulus than under no-stimulus schedules. The results limit the extension of the matching relation typically observed under simple concurrent variable-interval schedules to concurrent second-order variable-interval schedules.     

SEVERE CLASSROOM BEHAVIOR PROBLEMS: TEACHERS OR COUNSELLORS

This experiment was designed to determine the relative effectiveness of teacher and counselling approaches in the reduction of disruptive or inappropriate classroom behavior. Inappropriate classroom behavior frequencies of 12 academically low achieving, seventh-grade, black male students, with a reported high rate of inappropriate classroom behavior, were recorded. Three groups, with nearly equal mean inappropriate behaviors, were randomly assigned to one of three treatment conditions: behavioral counselling, client-centered counselling, or no counselling. Each counselling group received fifteen 30-minute counselling sessions, at a rate of two to three times a week. In addition to counselling, all students subsequently received teacher approval within the classroom. Results indicated that the teacher was able to reduce inappropriate behavior more than any counselling group. There were also indications that behavioral counselling, but not client-centered counselling, was moderately helpful in reducing inappropriate classroom behavior.     

The Future of Training and Credentialing in Group Psychotherapy

High-quality group psychotherapy training is seen as more important than ever in the current health care environment. The training opportunities available at present are assessed. It is argued that there is a body of knowledge about generic group psychotherapy that can and should be taught, and that there are appropriate people to teach it. Credentialing is discussed, and it is suggested that the assessment of actual work in clinical situations must be emphasized if such efforts are to be meaningful.     

Adolescent Health Care Training in Predoctoral Psychology Internship Programs: A Model of Interdisciplinary Training Needs in Health Care

This needs assessment of predoctoral psychology programs in a large southeastern state reveals that although many programs include adolescent health issues and often involve the psychiatry discipline in their curricula, many trainees do not have exposure to medicine, nutrition, or nursing disciplines. Opportunities for greater interdisciplinary adolescent health care training exist in psychology training programs in this southeastern state. Integrating such training into psychology programs may enhance psychology's ability to function as a vital component of adolescent health care teams within academic medical centers across the country.     

THE EFFECTIVENESS OF INTERPERSONAL SKILLS TRAINING ON THE SOCIAL SKILL ACQUISITION OF MODERATELY AND MILDLY RETARDED ADULTS

Sixteen moderately and mildly retarded adults were selected from a group residential facility and randomly assigned to experimental and control groups. The experimental group received a 12-session interpersonal skills training program consisting of instruction in the following areas: (1) Introductions and Small Talk, (2) Asking for Help, (3) Differing with Others, and (4) Handling Criticism. The social skills instructional package included verbal instruction, modeling, role playing, feedback, contingent incentives, and homework. As a result of this training program, moderately and mildly retarded adults acquired new social skills as evidenced by performance on a situation role play assessment. These gains generalized to untrained role play situations but did not result in significant group differences when assessed in a more natural setting (i.e., local grocery store).     

CORRESPONDENCE TRAINING: AN EXAMPLE OF RULE-GOVERNED BEHAVIOR?

Two groups of six mentally retarded adults were exposed to either a “say/do” correspondence training program or a “do only” reinforcement procedure to evaluate the suggestion of Rogers-Warren and Baer (1976) that reinforcement of the nonverbal target behavior in the absence of the relevant verbal behavior may account for the behavior changes seen in correspondence training. The participants worked in an experimental setting on a variety of manipulatory responses leading to various auditory and visual consequences. Analysis of individual patterns of responding indicated no apparent differences between the groups during training; four individuals in each group appeared to develop generalized correspondence skills. We conclude that the outcome of correspondence training may not necessarily be verbal regulation of behavior as is assumed. Rather, we suggest that the notion of rule-governed behavior can best account for the type of behavior changes seen in correspondence studies.     

Effects of reinforcement magnitude on spontaneous recovery.

Extinction of operant behavior has been associated with a number of undesirable effects. One such effect is the temporary reappearance of behavior after responding appears to be completely extinguished, known as spontaneous recovery. In this report, the occurrence of spontaneous recovery and its attenuation with large amounts of reinforcement were examined during the treatment of disruption.     

A COMPARISON OF PEER-DIRECTED AND TEACHER-DIRECTED EMPLOYMENT INTERVIEW TRAINING FOR MENTALLY RETARDED ADULTS

Interview skills deficits may limit employment prospects of mentally retarded adults. Although numerous papers highlight the importance of interview skills, few have validated effective strategies for use with mentally retarded persons. Further, there has been a lack of research contrasting rival interview skills training strategies. The present study was conducted with two mentally retarded young adults. It contrasted peer-directed instruction, in which both participants were equally deficient in the target skills, with teacher-directed instruction. Results of the investigation indicated that instruction, rehearsal, and feedback may be effective strategies regardless of who provides instruction. Comparisons of teacher-directed and peer-directed instruction indicated little or no difference in the effectiveness of the two procedures. However, the peer-directed procedure involved considerably less staff time than did the teacher-directed procedure.
