ON THE RELATIONSHIP BETWEEN SELF-INJURIOUS BEHAVIOR AND SELF-RESTRAINT

Many individuals who exhibit self-injurious behavior (SIB) also exhibit self-restraint. Three hypotheses about the determinants of self-restraint have been suggested: (a) Self-restraint is maintained by escape from or avoidance of aversive aspects of SIB, (b) self-restraint and SIB are members of the same functional class, and (c) self-restraint and SIB are functionally independent. This study examined a method by which the relationship between self-restraint and SIB may be investigated using functional analysis. Data were collected on the self-restraint and SIB exhibited by 5 mentally retarded males, while conditions suspected to maintain SIB were manipulated. Results suggested that self-restraint, like SIB, may be maintained by idiosyncratic contingencies. Implications of an understanding of self-restraint for the analysis and treatment of SIB are discussed, as are some general possibilities for future research.     

GENTLE TEACHING AND APPLIED BEHAVIOR ANALYSIS: A CRITICAL REVIEW

In recent years, there has been a growing controversy surrounding gentle teaching. This paper explores the nature of this controversy with particular reference to the relationship between gentle teaching and applied behavior analysis. Advantages and disadvantages of this approach are discussed, and it is suggested that gentle teaching and applied behavior analysis need not be regarded as mutually exclusive approaches to working with persons with mental retardation.     

Effects of self-generated rules on the development of schedule-controlled behavior.

College students responded under a multiple differential-reinforcement-of-low-rate 5-s fixed-ratio 8 schedule, with components alternating every 2 min. After 40 programmed minutes of acquisition and 12 min of maintenance, without notice, both schedules changed to extinction for 28 min. During acquisition, between alternations of the multiple schedule, some subjects were asked to develop rules describing the schedule contingencies. Other subjects were given these same rules between alternations, and a third group neither received nor were asked to develop rules. By the end of the acquisition phase, self-generated-rule subjects were more likely to show schedule-typical behavior than were subjects not asked to generate rules. The behavior of those given rules was similar to those asked to generate rules at the end of acquisition, but yoked-rule subjects acquired schedule-typical behavior at a quicker rate. By the end of extinction, during the period corresponding to the previous fixed-ratio interval, all no-rule subjects who had earned points during acquisition and maintenance were responding at a rate of less than 30 responses per minute. Only 3 of the 9 self-generated-rule subjects and 2 of the 5 yoked-rule subjects were similarly responding at this low rate. Results suggest that asking subjects to develop self-rules facilitates acquisition, but can retard extinction. Results also suggest that self-generated rules function similarly to external rules.     

Applying linear systems analysis to dynamic behavior

In this paper we present an abbreviated discussion of the linear systems analysis in the time domain. We then consider the qualitative character of the behavioral dynamics predicted using the linear form of the analysis. The analysis is then extended to a second-order form. We illustrate some relevant new features introduced by the second-order form with a special case example.     

Schedule-induced defecation: No-food and massed-food baselines

Defecation rate was monitored during daily 30-min periods as 16 rats were exposed to different sequences of the following three experimental conditions: (a) a fixed-time 60-s food delivery schedule, (b) a massed-food presentation baseline, and/or (c) a no-food baseline. All food delivery was response independent. Rate of defecation increased during fixed-time 60-s food delivery when compared to baseline rates of defecation established during no-food and massed-food baselines. This effect was present for 12 of 16 rats during four alternative sequences of experimental conditions. Within-subject reversals established reliability of this effect. Schedule induction of defecation is clearly demonstrated under these conditions.     

课堂情境中学生竞争对其成就归因和成就行为的影响

本研究把成就归因区分为倾向性成就归因和情境性成就归因两种类型,并分别检验了在课堂情境中学生之间的竞争对二者以及对成就行为的影响。被试是80名初中一年级学生。结果表明,(1)竞争对学生的倾向性成就归因没有明显影响,而显著地影响着学生的情境性成就归因;(2)竞争对学生随后成就行为没有明显影响;(3)倾向性成就归因对学生的成就行为的影响是显著的,但是它的这种影响却是间接发挥作用的。     

Decomposing coronary-prone behavior: Dimensions of type a behavior in the Videotaped Structured Interview

This study examined the factorial structure of data generated in the Videotaped Structured Interview for assessment of Type A behavior. Based on the literature, it was argued that there are at least three distinct concepts of Type A behavior, focused on competitiveness and pressured drive, speech characteristics, and hostility, respectively. These three concepts were clearly represented among the factors from factor analyses based on data from 282 subjects. Three factors represented speech and psychomotor characteristics, where the first reflected interactions between subject and interviewer (e.g., response latency, interruptions), the second tempo of speech (accelerating, dysrhythmic and rapid speech), and the third oral gestures (e.g., expiratory sighs). Hostility was reflected in two factors, one defined by emotional intensity (e.g., anger when recalling paat event) and the other hostility expressed towards the interviewer. Pressured drive dominated a content factor reflecting self-awareness of Type A behavior. Finally, there was one factor related to psychomotor tension. Through further factor and item analyses, it was possible to combine these factors into three homogeneous and moderately intercorrelated subscales of Type A behavior reflecting Hostility, Speech Characteristics, and Self-Awareness of Type A behavior. These scales showed good interrater agreement and stability over two years. The Self-Awareness Scale was highly correlated with self-report measures of Type A behavior. The Hostility Scale, on the other hand, was moderately related to measures of Type A behavior, anger and hostility, but was unrelated to anxiety. The Speech Characteristic Scale, finally, was virtually unrelated to psychometric measures.     

How parents view professional behaviors: A cross-professional analysis

This study examined the responses of more than 900 parents of children with serious emotional disorders to survey questions about the importance and frequency of professional behaviors and compared these responses across professions. The findings indicated that parents with lower income and less education tended to work more with social workers, counselors, and teachers, less with psychologists and psychiatrists. Professional behaviors concerned with the parent-professional relationship, honesty, non-blaming attitude, supportiveness, and inclusion in decision-making were considered important by most parents regardless of the professional with whom they worked. Parents rated professions differently on the importance of evaluation, home visits, and providing child-raising information, probably reflecting expectations that parents have about the roles and training of professionals. The behaviors that parents considered important also tended to occur frequently. Significant differences across professions were found with respect to the frequency of providing information on child rearing, advocacy, home visits, providing information on resources, and help with coping, although these behaviors were considered relatively less important by parents. An examination of discrepancies between what parents considered important and what they experienced suggested that parents' expectations were only partially met. Implications for practice, professional education, and research are discussed.Editor's Note: We acknowledge the sampling issue raised by the low survey return rate in this study and the resulting threat to generalizability of findings. Nevertheless, the study is judged to merit publication as one of the first efforts to examine empirically parents' views of their relationships with mental health professionals. Our hope is that this report will serve to stimulate further scientific investigation on the topic—Donald Oswald (AE).     

Evaluating treatment effects in single-subject behavioral experiments using quality-control charts

Quality-control charts can be particularly useful in identifying treatment effects and patterns of behaviors in single-subject behavior-analytic experiments that cannot be determined by visual inspection of their graphs. Using an example from the behavior analysis literature the quality-control charts identified the presence of treatment effects across phases as well as the presence of trends within and between phases. The ease of their calculations suggest use of them by behavior analysts whenever the effects of particular interventions are questionable.
