Replication of a high-probability request sequence with varied interprompt times in a preschool setting

An intervention for noncompliance consisting of a series of requests promoting a high probability of compliance followed either 5 s or 20 s later by a request with a low probability of compliance was implemented with a preschool child with autism. Results indicated that applications of the request sequence with a shorter interprompt time resulted in higher rates of compliance, and longer interprompt times resulted in near-baseline rates of compliance.     

MULTICOMPONENT INTERVENTION FOR AGITATED BEHAVIOR IN A PERSON WITH ALZHEIMER'S DISEASE

We evaluated a multicomponent intervention for agitated behavior in a man with probable Alzheimer's disease. Hypotheses about variables controlling his agitated behavior guided intervention design. Based on staff interviews, direct observations, and brief experimental probes, intervention components were chosen to increase rate of reinforcement and decrease aversive aspects of his job. Intervention reduced agitated behavior without disrupting his work rate.     

Basic research needed for stimulating the development of behavioral technologies

The costs of disconnection between the basic and applied sectors of behavior analysis are reviewed, and some solutions to these problems are proposed. Central to these solutions are collaborations between basic and applied behavioral scientists in programmatic research that addresses the behavioral basis and solution of human behavior problems. This kind of collaboration parallels the deliberate interactions between basic and applied researchers that have proven to be so profitable in other scientific fields, such as medicine. Basic research questions of particular relevance to the development of behavioral technologies are posed in the following areas: response allocation, resistance to change, countercontrol, formation and differentiation/discrimination of stimulus and response classes, analysis of low-rate behavior, and rule-governed behavior. Three interrelated strategies to build connections between the basic and applied analysis of behavior are identified: (a) the development of nonhuman animal models of human behavior problems using operations that parallel plausible human circumstances, (b) replication of the modeled relations with human subjects in the operant laboratory, and (c) tests of the generality of the model with actual human problems in natural settings.     

Contrast and undermatching with regular or irregular alternation of components

Behavioral contrast and response-ratio sensitivity to reinforcement were compared in multiple schedules in which components alternated strictly or according to a pseudorandom sequence. Average component durations in the two regimes were always 60 s, and order of presentation of component alternation regimes was counterbalanced across subjects. In Part 1, the reinforcer rate in one component was reduced from 60 per hour to zero, while that in the other component was unchanged. Positive behavioral contrast occurred in the constant component in that response rates increased, but neither the reliability nor the magnitude of contrast was affected by the manner in which components alternated. Part 2 was similar, except that a number of different reinforcer rates were used in the varied component. Neither contrast nor sensitivity of response ratios to changes in reinforcer ratios depended on the regime of component alternation. Thus, the predictability in time of future reinforcement conditions, which is a feature of regular multiple scheduling, does not appear to be a determinant of multiple-schedule performance.     

Tolerance to cocaine's rate-increasing effects upon repeated administration.

Four squirrel monkeys responded daily under a fixed-interval 5-min or 8-min schedule of food-pellet delivery. Cocaine (0.03 to 1.7 mg/kg) and saline were injected before occasional daily sessions (acute administration). Some doses of cocaine produced substantial overall increases in response rate for 3 of the subjects; effects were less substantial for the remaining subject, who exhibited modest increases in response rate early in the session and during the middle portion of the intervals. A dose that increased response rate when administered acutely was then administered before each session (chronic administration). Chronic administration resulted in a reduction in the increases in response rate seen under acute administration for all subjects.     

In-home treatment for families in crisis and its supervision: A systemic multi-level approach

The author discusses his experience with a five-phase model which built on congruency at all systemic levels of in-home family treatment and its supervision. Five phases are presented, as well as the group process during supervision. In-home family treatment confronts the family helper with different tasks in each phase of the treatment process and with different expectations within the professional network and the institutional context.The author's work as a supervisor and trainer of in-home family treatment was made possible by Diakonisches Werk Hannover. Grateful acknowledgment is made to Heike Müller, Claudia Eckert, and all their colleagues for their trust and support, to Winiger Beuse for his professional friendship, and most importantly to Dr. Carole Gammer and Prof. Dr. Martin Kirschenbaum for their helpful comments on an earlier version of this paper. Thank you Sandy and Susan. In this article the German expression Sozialpädagogischer/r Familienhelfer/in is translated into family helper. In Hannover, as in many other German cities, family helpers are graduate social workers. Family therapy training is not obligatory but appreciated.     

Structural family therapy with Mexican-American family systems

Characteristics of traditional Mexican-American families with consequent family rules that affect these family systems are discussed along with selected clinical cases. The specific cases discussed involve: (1) interactions with family of origin in intercultural marriages, (2) intracultural differences in levels of acculturation and traditional family rules, and (3) extended family impact in response to severe life crisis. The development of therapeutic processes from structural and strategic family therapy approaches, which reflect appreciation for cultural differences and strengths, is suggested.This material was presented at the annual meeting of the Texas Association for Marriage and Family Therapy, January, 1994, San Antonio, TX.     

“Operationalism” in psychotherapy: A possible means of putting a sorry state of theory in better order?

It will be shown in this paper that the study of the actual conduct of psychotherapy, at least in its classical form with a patient speaking his or her mind in any way the patient desires and a therapist helping the patient pursue those thoughts and wishes and conflicts and hopes for better luck in real life than before, is more conducive to agreement among rather different therapists, to clearer reasoning over psychotherapeutic interventions, and to more promising theoretical articulations than anything available in the theoretical texts of psychotherapy.     

Fostering a safe atmosphere: A first step in discussing gender in family therapy training programs

Several important aspects of raising gender issues in family therapy training programs have been identified in the last few years. However, an important first step has often not been made explicit: the need to establish an open and safe environment in which these issues can be discussed. Such a safe environment can be developed by using theoretical perspectives with which family therapy students and faculty are already familiar. This paper offers three theoretical perspectives as examples and makes suggestions for facilitating an atmosphere that is conducive to discussing gender issues.The author wishes to thank Dr. Fred P. Piercy for his helpful comments and contributions to this paper.     

Memory for a dialectical and a nondialectical prose passage in young and older adults

Age differences in adults' processing of a dialectical or nondialectical prose passage were explored. Twenty young and 20 older adults read a dialectical or mechanistic passage and were tested for free recall and recognition after a 30-min delay (filled with vocabulary and paradigm belief scale). Older (vs. young) adults had significantly lower formistic and mechanistic scores and showed greater relative preference for relativistic and dialectical beliefs (paradigm scale). There were no age differences in amount of free recall or number of correct responses (hits) on recognition, but older adults produced more spontaneous dialectical distortions in recall of the mechanistic passage and more paradigm-congruent false alarms on recognition. There was also a move from absolute toward dialectical thinking on the paradigm scale and, among males, on the recognition measure. Dialectical scores (paradigm scale) were positively correlated, and mechanistic scores negatively correlated, with number of dialectical distortions on free recall (mechanistic passage), while dialectical scores were positively correlated with number of dialectical false alarms (dialectical passage).
