Level of school education and performance on an intelligence test were analysed for 32 557 Danish young adult males as a function of the geographical region in which they were reared. Positive associations were found between both educational levels and test scores on the one hand, and the proportion of infants attending kindergartens in the given regions (according to official statistics) on the other. Adults who were reared in regions where kindergarten attendance had been high tended to have higher educational levels and test scores, although the data do not permit a precise estimate of the magnitude of this effect. The relationship between kindergarten attendance and intelligence test score appears to have been mediated by educational level. Kindergarten attendance was more common in regions with high population density and high average incomes but the relationship of kindergarten attendance to educational level was significantly independent of these associations. These findings are consistent with the hypothesis that kindergarten attendance can have long-term educational benefits, and might therefore partially explain the upward trend in intelligence test scores over the last few decades.  相似文献

Two experiments are reported concerning the effects of the differential use of verbal approval by problematic adolescents serving as tutors in a remedial reading program for an inner-city school. The experiments, each with 3 tutors and 15 tutees, used a combined multiple baseline and ABCBC design. Data showed that tutors' approvals as well as tutors' and tutees' on-task and reading responses were low and stable during baseline. Tutors were trained to use verbal approval for tutees' on-task behavior. Tokens were presented and withdrawn to control the tutors' use of approval. During phases in which tutors' approvals were raised via token dispensation, tutor reading and on-task scores increased in a nonexperimental setting. Tutee reading scores also increased as a function of tutor approvals. The second experiment replicated these findings and, in addition, (a) tested the validity of changes in reading responses via standardized tests, (b) isolated and compared the covariance between variables in all phases, and (c) provided data on tutee attention to tutors as a possible natural reinforcer for the short-term maintenance found in both studies. Data are discussed as evidence that tutors had acquired the ability to recruit reinforcement from the classroom for appropriate behavior.  相似文献

The findings of the three experiments reported herein indicate that normal children can successfully teach social responses (i.e., delayed imitation, cooperative play, and verbalization of positive comments) to withdrawn mentally retarded peers. The effects of the intervention generalized across stimulus and response conditions, while the trained and generalized levels of responding were maintained after the end of the intervention. Moreover, the subjects developed social responding within their classrooms and play areas parallel to the intervention and continued to increase such responding after the interruption of the intervention. Direct edible reinforcement appeared to be necessary at least during the initial period of the intervention. Vicarious edible reinforcement seemed useful to prompt the appearance of responding. Vicarious social reinforcement was ineffective at the beginning of the intervention, but apparently acquired prompting power at a later stage of training. Generalization results indicated that the similarity between the response occasions used for training and those used for testing generalization played an important role. Yet, the extensiveness of training and the development of responding within the classrooms and play areas may also have had a relevant effect. The development of social responding within the classrooms and play areas appeared to be mainly the effect of new learning. This was perhaps due to vicarious and direct social reinforcement.  相似文献

There has been little research on the effects of the many procedural variables in applied group contingencies. In the present study, an individualized contingency and three group contingencies with different “responder” criteria (e.g., reward based on the group average, reward based on the work of a designated, low-achieving student, or reward based on the work of a randomly selected student) were applied to the academic work of primary grade children in a learning disabilities classroom. Group social interaction during each contingency was measured systematically. Although there were large individual differences in students' academic and social responses to the different contingencies, some consistent effects were observed. Two of the four low-achieving target students did their best academic work during the group contingency which focused on their performance as a designated responder. This type of contingency also produced high levels of positive social interaction in three of four groups of children observed.  相似文献

The concurrent and predictive validity of four qualitative behavioral classes of social interaction (initiating and receiving positive and negative social interaction) was investigated using sociometric measures of peer acceptance (ratings) and friendship (nominations). Correlational analyses showed significant relationships between behavioral and sociometric measures supporting previous work with preschool populations. Stepwise multiple regression analyses suggested that receiving social interaction from peers best predicted overall acceptance, whereas initiating social interactions best predicted children's friendship patterns. Tentative implications for the behavioral assessment of children's social skills were discussed.The current data were gathered as part of a larger research project concerning social skills assessment and training in children.  相似文献

This study was designed as a preliminary step in evaluating the adequacy of a role play of a previous event. Sixty undergraduate males, high or low in social anxiety, interacted with a female assistant. Two groups of subjects then rehearsed this conversation overtly or covertly, while a third group became involved in a distraction task. Finally, all subjects role played the initial interaction with a second female assistant. Individual Pearson product-moment correlations between the initial and the role-play sessions yielded moderate, but significant correlations for most of the rated behaviors. Canonical correlations for the verbal and for the nonverbal ratings showed the two sessions, as a whole, highly related. Two (high-versus low-social anxiety group) × three (overt, covert, or no rehearsal) analyses of variance were performed on four measures. Significant results were found only for the anxiety group effect and rehearsal group effect on one rating, anxiety behaviors. The implications of the modest individual correlations suggest that estimation of specific levels of behavior is not appropriate from a role play of a previous event. However, the use of such a role play to make global distinctions of relative competence may be appropriate. The results of this study are consonant with earlier studies on role-play assessment.This article is based on a master's thesis completed by the first author in partial fulfillment of the requirements for the Master of Science degree at Ohio University.  相似文献

A comprehensive validation study was conducted of the Program for Academic Survival Skills (PASS), a consultant-based, teacher-mediated program for student classroom behavior. The study addressed questions related to: (a) brief consultant training, (b) subsequent teacher training by consultants using PASS manuals, (c) contrasts between PASS experimental teachers and students and equivalent controls on measures of teacher management skills, student classroom behavior, teacher ratings of student problem behaviors, and academic achievement, (d) reported satisfaction of participants, and (e) replication of effects across two separate school sites. Results indicated that in both sites significant effects were noted in favor of the PASS experimental group for (a) teacher approval, (b) student appropriate classroom behavior, and (c) four categories of student inappropriate behavior. Program satisfaction ratings of students, teachers, and consultants were uniformly positive, and continued use of the program was reported a year later. Discussion focused upon issues of cost-effectiveness, differential site effects, and the relationship between appropriate classroom behavior and academic achievement.  相似文献

Approximately 50% of all institutionalized, mentally retarded adults receive psychotropic medication to control inappropriate behavior. In this study, behaviors exhibited by five retarded adults were formally observed while they were on and off medication. Each subject had been receiving chlorpromazine for six or more years prior to the start of the study. The drug was withdrawn and readministered using a double-blind B-A-B (drug-placebo-drug) design. Effects were highly individualized. Some desirable behavior emerged when chlorpromazine was discontinued.  相似文献

Several social and research issues directly affected the development and implementation of multivariate assessment in a large community-based applied research program. Examples are drawn from experiences of the Preparation through Responsive Educational Programs Project for disruptive and skill deficient adolescents in suburban, rural, and urban junior high school settings, focusing on the assessment of academic and social skill development and long-term skill maintenance. The social context altered both project treatment and follow-up plans, requiring assessment of potentially unintended effects and decreasing consistency across sites. Future community acceptance of such programs may depend on the investigators' adaptation to diverse community pressures for program conduct and assessment and the measurement of phenomena that are not always directly observable.  相似文献

Social approach to peers was evaluated as an intervention for isolate preschoolers. During baseline, confederate peers made few social approaches to the target subjects. Confederates greatly increased their rate of social approaches during the first intervention, decreased social approaches during a second baseline, and increased social approaches again in a second intervention phase. Increases in confederate social initiations immediately increased the frequency of subjects' positive social behavior. Additionally, five of six subjects showed an increase in their own positive social initiations during intervention periods. The results suggest that: (a) peers may be programmed to increase the positive social behaviors of their isolate classmates, and (b) remediating social deficits requires assessment and intervention specifically tailored to the individual child.  相似文献
