This study illustrated the use of normative behavioral observation data as a standard for evaluating the practicality of treatment effects produced in other settings. Three groups of eight subjects each, displaying relatively low proportions of appropriate classroom behavior when compared with regular classroom peers, were selected for treatment within an experimental classroom setting. The three groups were exposed to intervention procedures designed to reinforce either direct academic performance and/or facilitative nonacademic classroom responses. The treatment was effective in changing levels of appropriate behavior (1) above baseline levels in the experimental classroom, and (2) to within normal peer-defined limits when reintegrated into the regular classroom. Further, the data reflect successful maintenance of these effects for a seven- to 12-week follow-up period. Several applications of a normative model for evaluating treatment, generalization, and maintenance effects were presented and discussed. 相似文献

Juvenile crime is a serious problem for which no treatment approach has been found to be reliably effective. This outcome evaluation assessed during and posttreatment effectiveness of Teaching-Family group home treatment programs for juvenile offenders. The evaluation included the original Achievement Place program, which was the prototype for the development of the Teaching-Family treatment approach, 12 replications of Achievement Place, and 9 comparison group home programs. Primary dependent measures were retrieved from court and police files and included number of alleged offenses, percentage of youths involved in those alleged offenses, and percentage of youths institutionalized. Other dependent measures were subjective ratings of effectiveness obtained from the program consumers, including the group home residents. The results showed difference during treatment favoring the Teaching-Family programs on rate of alleged criminal offenses, percentage of youths involved in those offenses, and consumer ratings of the programs. The consumer ratings provided by the youths and their school teachers were found to be inversely and significantly correlated with the reduction of criminal offenses during treatment. There were no significant differences during treatment on measures of noncriminal offenses (e.g., truancy, runaway, and curfew violations). In the posttreatment year, none of the differences between the groups was significant on any of the outcome measures. The results are discussed in terms of measurement and design issues in the evaluation of delinquency treatment programs and in relation to the evaluation of Teaching-Family group homes by Richard Jones and his colleagues. 相似文献

PINDIS, as recently presented by Lingoes and Borg [1978] not only marks the latest development within the scope of individual differences scaling, but, may be of benefit in some closely related topics, such as target analysis. Decisions on whether the various models available from PINDIS fit fallible data are relatively arbitrary, however, since a statistical theory of the fit measures is lacking. Using Monte Carlo simulation, expected fit measures as well as some related statistics were therefore obtained by scaling sets of 4(4)24 random configurations of 5(5)30 objects in 2, 3, and 4 dimensions (individual differences case) and by fitting one random configuration to a fixed random target for 5(5)30 objects in 2, 3, and 4 dimensions (target analysis case). Applications are presented. 相似文献

Program evaluation can provide objective information relevant to decisions on program maintenance. A program to address problems in the preparation of criminal investigation reports in a metropolitan police department was evaluated. The program permanently altered environmental conditions under which reports were prepared to facilitate performance. Police officers, who had previously prepared reports without assistance, visited the Case Preparation Room to prepare reports with assistance from office personnel. Compared to reports prepared without assistance, reports prepared in the Case Preparation Room documented more case elements required by the state legal code for criminal prosecution, were completed in fewer days following arrests, and received higher ratings from Assistant District Attorneys. Operation of a permanent program available to approximately 945 officers proved a practical solution to improving the preparation of criminal investigation reports. 相似文献

The central question addressed was, how effective is parent training in reducing conduct problems in children in comparison to client-centered parent counseling? A secondary question was the relative effectiveness of the two treatment groups in comparison to a wait control group that when untreated during the 8-week period of treatment provided the other groups. Families of 36, 5- to 12-year-old conduct problem children were screened and assigned at random to treatment groups, but wait control group assignment depended upon therapist availability. Supervised graduate student therapists conducted 10 treatment sessions for each family. Parent reports and paper and pencil tests of child deviance and parent satisfaction showed a superior outcome for behavioral over the client-centered and wait control groups, and no differences between the latter two groups. At follow-up there was no maintenance of this superiority. Home observation data showed no advantage of behavioral over client-centered treatment, and these two groups did not improve significantly more than the wait control group. These results were discussed in the light of possible interactions between treatment and measurement, and methodological and sampling differences between this and other studies. 相似文献

时序信息加工机制及其通道效应的实验研究 总被引:5,自引:2,他引:3
研究由两个实验组成,实验一采用纯粹的视听方式,以线段长度和声音频率为材料,对时序信息的加工方式(自动加工与控制加工)、编码特点(时序信息是何时编码的)以及通道效应进行了研究。实验二以汉字为材料重复实验一的过程;结果表明,时序信息的加工存在视听通道效应,其机制源于记忆,且与实验材料的加工深度以及加工方式有关;时序信息既包含有自动加工,又包含有控制加工。视觉刺激倾向于自动加工,而听觉则倾向于控制加工;时序信息是在项目学习时编码获得的,而不是在提取时建构的。 相似文献

Hand mouthing often has been described as a stereotypic response that is maintained by non-social (automatic) reinforcement; however, data supporting this conclusion can be found in relatively few studies. This series of studies presents an experimental analysis of conditions associated with the maintenance of hand mouthing. In Experiment 1, a functional analysis was conducted for 12 individuals who engaged in chronic hand mouthing to determine whether the behavior is usually maintained independent of social contingencies. Results obtained for 10 subjects were consistent with an automatic reinforcement hypothesis; the remaining 2 subjects' hand mouthing was maintained by social-positive reinforcement. Based on these results, Experiment 2 was designed to identify the specific reinforcing properties of hand mouthing. Each of 4 subjects was provided with a toy that substituted for hand mouthing, and preference for a specific topography of toy manipulation (hand-toy contact or mouth-toy contact) was measured. Results indicated that hand stimulation was the predominant reinforcer for all subjects. Experiment 3 provided an extension of Experiment 2 in that the same responses were measured across a variety of toys presented to each of 5 subjects. Results again indicated that hand stimulation was the predominant reinforcer for all subjects. Implications of these results are discussed with relevance to treatment. 相似文献

The aim of the present study was to explore how rapid emotional responses are manifested as facial electromyographic (EMG) reactions when people with explicit fear of snakes are exposed to their fear relevant stimuli. Fifty-six subjects, high or low in fear of snakes, were exposed to pictures of snakes and flowers while facial EMG activity from the corrugator supercilii and the zygomatic major muscle regions was recorded. Measures of autonomic activity and ratings of the stimuli were also collected. Pictures of snakes evoked a rapid corrugator supercilii muscle reaction which was larger in the High fear group as early as 500ms after stimulus onset. The High fear group also rated snakes as more unpleasant and displayed larger skin conductance responses (SCRs) and increased heart rate (HR) when exposed to snakes. Pictures of flowers tended to evoke increased zygomatic major muscle activity which did not differ among the groups. The present results demonstrate that the facial EMG technique is sensitive enough to detect rapidly evoked negative emotional reactions. The results support the hypothesis that people high in fear of snakes are disposed to react very rapidly with a negative emotional response to their fear relevant stimuli. 相似文献

The variability in the behavioral equilibrium established by six basic schedules was characterized. The measures were the pause preceding the first response in each interreinforcement interval; the mean rate of responding in each interreinforcement interval; and the relative frequency of each interresponse time. The temporal windows ranged across the 780-session exposure, across a session, and across the interreinforcement interval. A display of individual interresponse times as a function of time in the interreinforcement interval indicated clear recurrent responding at somewhat less than 3 Hz in every bird, even after extended exposure to a schedule and regardless of the contingency. No strong sequential dependencies in the interresponse-time distributions were identified. A simulator, based on a simple recurrent pulser, was presented that produced output similar to the obtained data. An archival data base of the behavior chronically maintained by the simple schedules was also generated. 相似文献
