Efficacy of constant time delay implemented by peer tutors in general education classrooms

We evaluated the effects of teaching 13 typically developing children to use constant time delay when tutoring three of their peers who had substantial disabilities. We measured the extent to which the tutors used the constant time delay procedure correctly and the tutees' correct performance on the skills being taught. A multiple probe design across behaviors was used. The results indicated that (a) the tutors used each step of the constant time delay with a high degree of procedural fidelity; (b) the students with disabilities acquired the skills that were taught during peer tutoring; and (c) modifications of the procedure were required for 2 of the 3 students with disabilities, and the peers tutors were able to implement the modifications. Implications for practice and future research are described.     

What influences the quality of care in English playgroups?

In a study of the quality of care, interviews and observations of 45 playgroups in three areas of England were conducted. The Early Childhood Environment Rating Scale was used as a measure of quality. The influence of area, resources, management, size, space, staffing, training, support, parental involvement and staff dissatisfaction upon quality were considered. The major influence was playgroup leader training, and parental involvement was also associated with quality of care. Parental involvement and staff training were strongly linked, indicating the confounding of family and child care characteristics and the importance of understanding family and child care interrelationships. The applicability of the measures to English playgroups was discussed.     

不同刺激强度训练后一日龄小鸡的记忆形成

一日龄小鸡,分别接受不同浓度的回避性刺激物邻氨基苯甲酸甲酯（ＭｅＡ）训练,间隔一定时间后测试记忆保持。主要结果为：５％和２０％ＭｅＡ训练,分别使动物记忆保持１５分钟和５０分钟左右,相当于记忆形成多阶段模型中的ＳＴＭ和ＩＴＭ阶段。４０％ＭｅＡ训练,记忆保持到训练后８－１０小时,相当于不依赖新糖蛋白合成的ＬＴＭ形成的早期阶段。只有６０％以上浓度的ＭｅＡ训练才使记忆保持至少２４小时。上述结果提示,利用弱化训练的方法,不仅可以将ＳＴＭ,ＩＴＭ和ＬＴＭ分离开,而且可把ＬＴＭ形成的早期阶段分离出来独立研究,增加了对ＬＴＭ新的理解,为进一步探讨记忆形成机制提供了一条新的途径。     

The Effectiveness of Audiovisual Self-Instructional Materials in Teaching Child-Care Skills to Parents with Intellectual Disabilities

Children of parents with intellectual disabilities are at risk for neglectful care due to parenting skill deficiencies. Previous studies have shown that parents with intellectual disabilities can improve child-care skills with intensive behavioral training, but self-instruction has not been explored. We evaluated the efficacy of self-instructional pictorial child-care manuals with and without accompanying audiotaped instruction using a multielement design with 13 parents with intellectual disabilities. The self-instructional materials were effective in teaching 22 of 26 skills to levels seen in parents without intellectual disabilities. Eighty-one percent of the skills maintained over a 1-15 month follow-up period and self-learning effects were replicated when the parents received self-instructional materials for the original no-training control skill. Despite the low literacy skills of the parents, for most of them no advantage was found in adding the audiotape to the illustrations. Three parents only reached criterion after an audiotape was added to the manual alone skill. Consumer satisfaction ratings were uniformly high and those parents who stated a preference, preferred the pictorial manuals without, as opposed to with, the audiotape. These findings suggest that a majority of parents with intellectual disabilities may improve their parenting skills with low cost, low tech, self-instructional materials.     

Body weight and response acquisition with delayed reinforcement.

The relation between body weight and responding established with unsignaled delayed reinforcement was investigated. In three experiments, naive rats were deprived to either 70%, 80%, or 90% of ad libitum weight and were then exposed to tandem variable-interval 15-s differential-reinforcement-of-other-behavior 30-s schedules. The tandem schedule defined a resetting unsignaled delay-of-reinforcement procedure. In the first experiment, speed of magazine training, acquisition of lever pressing, and final rate of lever pressing were related to body weight. In the next experiment, lever pressing was established and maintained in rats that were magazine trained at 70% of ad libitum weight but that were then exposed to the delay procedure at 90% of ad libitum weight. Responding did not change consistently either across or within subjects in subsequent conditions in which body weight was manipulated. In the final experiment, lever pressing was established and maintained with delayed reinforcement in the absence of magazine training for each of 2 rats at 70% and for 1 of 2 rats at 90% of ad libitum weight. The results further illuminate the conditions under which responding can be established in the absence of training and when such responses are reinforced only following an unsignaled delay period.     

Report of the Working Group on Education and Training

Prepared by the Working Group on Education and Training from the November 1995 Georgetown conference sponsored by the Association of Medical School Psychologists, this paper focuses upon the education and training of psychologists and education and training of other health care professionals about psychology in academic medical settings. Seven specific topic recommendations are offered that help psychologists define their educational and training missions into the next century.     

Making psychology incorruptible

This paper is a response to criticisms, by Peterson (1995) and others, of positions I took in an earlier article, “Manifesto for a science of clinical psychology” (McFall, 1991). I had argued that professional practice and training in clinical psychology must be governed by a scientific epistemology, and had outlined some of the specific reasons and implications. In this article, I attempt to correct misinterpretations of my previous arguments, to clarify ambiguities, and to fill any serious omissions. The fundamental points of the original Manifesto are defended, buttressed, and extended. In response to issues highlighted by the criticisms, two new corollaries are added to those offered in the original article. These summarize the arguments presented in this paper, with special emphasis on the essential role of skepticism as the best protection against the corruption of knowledge and practice in psychology.     

Social skills training: The moderating influence of culture in the treatment of Latinos with schizophrenia

Providing effective psychiatric rehabilitation to ethnic minority patients with serious persistent mental illness (SPMI) requires an understanding of the role of cultural values and ethnicity-relevant factors on the course and outcome of severe mental disorders. In this paper, the author identifies some of the cultural factors that are relevant for Latinos with SPMI, and describes how these factors were incorporated into existing rehabilitation modalities. The results of a pilot study designed to test the efficacy of culturally-modified social skills training are presented. The results suggest that the cultural modifications improved Latino patients' ability to learn the material and enhanced their use of these skills in their natural environments. Future research will be aimed at identifying and incorporating these salutary cultural forces into the rehabilitation process of the severely mentally ill.     

EVALUATION OF CLIENT PREFERENCE FOR FUNCTION-BASED TREATMENT PACKAGES

Functional communication training (FCT) and noncontingent reinforcement (NCR) are commonly prescribed treatments that are based on the results of a functional analysis. Both treatments involve delivery of the reinforcer that is responsible for the maintenance of destructive behavior. One major difference between the two treatment procedures is that client responding determines reinforcement delivery with FCT (e.g., reinforcement of communication is delivered on a fixed-ratio 1 schedule) but not with NCR (e.g., reinforcement is delivered on a fixed-time 30-s schedule). In the current investigation, FCT and NCR were equally effective in reducing 2 participants' destructive behavior that was sensitive to attention as reinforcement. After the treatment analysis, the participants' relative preference for each treatment was evaluated using a modified concurrent-chains procedure. Both participants demonstrated a preference for the FCT procedure. The results are discussed in terms of treatment efficacy and preference for control over when reinforcement is delivered. In addition, a method is demonstrated in which clients with developmental disabilities can participate in selecting treatments that are designed to reduce their destructive behavior.     

DEFINING CHILD NONCOMPLIANCE: AN EXAMINATION OF TEMPORAL PARAMETERS

This study examined compliance parameters for 53 clinic-referred and nonreferred children, ages 2 to 10 years. Although there were significant differences between the referred and nonreferred samples for percentage compliance, there were no significant differences between the referred and nonreferred samples in terms of initiation or completion latencies. The average initiation latency was 5.92 s, whereas 98% of the sample initiated compliance within 14 s. Younger children did take longer to complete tasks. Results suggest that the use of short latencies in defining noncompliance may represent overly conservative criteria.
