The relationship between career maturity and self-concepts of 252 sixth-grade black males was investigated. Student samples of suburban and urban middle- and urban lower-class were drawn from 42 different school settings located in Monroe, Erie, and Westchester Counties of New York State. The Attitude Scale of the Career Maturity Inventory and the Coopersmith Self-Esteem Inventory were used to assess the association of career maturity and self-concepts. Results indicated relatively weak-positive relationships between career maturity and self-concepts. Significant career maturity differences were found. However, self-concepts of the three groups were not statistically significantly different. Of the set of independent variables predicting and estimating variance accounted for (socioeconomic status, family intactness, place of residence, and reading), socioeconomic status was found to have the strongest predictive value on career maturity. It was suggested that researchers examine elementary school black students' career development in view of the group with whom they identify most. 相似文献

Sixteen rats, eight with bipolar electrodes implanted bilaterally in the anterodorsal head of the caudate-putamen and eight with similar electrodes in the posteroventral caudate-putamen, learned a spatial and a form discrimination task and their reversals while receiving "continuous" stimulation. Rats receiving stimulation to the anterodorsal caudate-putamen were imparied on spatial reversal learning compared with the posteroventral group. On form discrimination reversal the posteroventral group were impaired compared with the anterodorsal group. This dissociation is related to the particular cortical neostriatal projection system for the region stimulated and demonstrates a behavioral differentiation in rat neostriatum comparable with that observed in the monkey. 相似文献

Residents of extended care facilities generally exhibit a low level of attendance at recreational and therapeutic activities. Spatial arrangement of rooms, prompting, snacks, and small prizes have been suggested as factors that affect attendance. The present study examined the effects of an extensive system of prompts and the location of activity areas on the attendance of residents at a variety of activities. Twenty-six subjects were randomly selected from the ambulatory population of the facility. The first time each subject entered the activity room during the first 6 min of an activity session their name was recorded. Reliability measures were taken at 10 sessions, with a 95% mean agreement between observers. The variables examined were the amount of individualization of subjects (experimental group I: names announced versus experimental group 2: names not announced), room location (central or peripheral), use of names in announcements (activity only versus activity and group I names), and mode of announcement (PA system only versus PA system and in-person). A counter-balanced group design with repeated measures was used, with a randomly determined order of application of experimental treatments. An analysis of variance split plot 2.222 (Kirk, R. E. Experimental Design: Procedures for the Behavioral Science. Belmont, Ca.: Brooks-Cole, 1968.) of the level of subject attendance yielded significant main effects for room location, F(1, 24) = 5.47, p < 0.05, and type of announcement, F(1, 24) = 9.10, p < 0.01, and significant interactions for Individualization × Use of Names in Announcements, F(1, 24) = 5.57, p < 0.05, and Room Location × Mode of Announcement, F(1, 24) = 7.90, p < 0.01. The results indicate that using a centrally located room and announcement of resident names increases attendance at a variety of activities. The increased social and environmental interaction generated by activity attendance has potential therapeutic benefits for the residents involved. Furthermore, the kind of information reported here and by others should be taken into consideration by planners of a variety of group living facilities, ranging from nursing homes to residential treatment cottages. 相似文献

Being able to assess one's own performance would seem to be prerequisite to most forms of self-management. The present study investigated the extent to which children in a typical second-grade classroom could accurately assess their own academic on-task behavior. In essence, this investigation replicated an experiment by Glynn and Thomas (Journal of Applied Behavior Analysis, 1974, 7 , 299–306) and extended those findings, by studying self-assessment over a longer span of time. The 31 children in the class ranged in age from 7 yr five months to 8 yr six months. Although only eight “problem” children were observed and studied, the self-control treatment procedures were applied to all children in the class. Behavior was observed daily during mathematics lessons for over eight school weeks. The study utilized a five-phase ABABC design, where the A phases were baseline periods, B phases were self-control periods, and C phase was a postcheck. In the self-control phases, children were asked by the teacher to put a check on their own individual performance card if they were on-task when a signal sounded. If they were not on-task, they were instructed not to touch their card. Typically, 15 to 20 signals occurred per 40-min session. At the end of the lesson, children were allowed to choose games to play according to how many checks they had earned. During all experimental phases, observers measured children's on-task behavior. Other observers measured the children's accuracy of self-assessment in the self-control phases. The results showed noticeable increases in the daily mean on-task behavior scores in the self-control phases following baseline phases. Also, a high level of on-task behavior was maintained in the postcheck phase. The variances of on-task behavior scores during the self-control phases were noticeably smaller than those in the baseline phases. Generally, individual data reflected group results, with some minor differences. Levels of accuracy of self-assessment varied from very accurate (95% of the time) to relatively inaccurate (56% of the time). The overall level of accuracy for all children was 78%. No consistent individual pattern appeared across phases. Some children got better as the study proceeded and some got worse. Most subjects tended to give themselves too much reinforcement, rather than too little. Peer social surveillance appeared to be the major factor that influenced individuals' evaluation of their own behavior, even though the teacher did make some control remarks in regard to how the children marked their cards. The results also demonstrated that self-control techniques can increase on-task behavior in a classroom with no history of external reinforcement, and that these techniques can have a lasting effect for more than two months of a school year. 相似文献

A segmented container called the V-box was designed to train adult subjects who fail a Piagetian type measure of the horizontality concept. The first segment appears round when viewed from straight an and virtually all adults were able to predict correctly howthe water line would appear when this segment was half filled with water. Partitions can be removed and the water allowed to fill up the entire container which has straight-line boundaries. On a pretest, 28 of 43 subjects failedto indicate the water line correctly on the container, when its straight-line characteristics were apparent. Of these 28, 18 were able to do so after being exposed gradually to the container's rounded segment and, step by step, to its elongated segments with straight-line boundaries. The difference in pre- to posttest change in performance between these 18 subjects and the 10 control subjects was significant. 相似文献

Four hamsters received brief electric shocks contingent upon running in a wheel. The fixed interval between shocks was varied systematically from 0 to 60 sec. Time spent running was directly related to the length of the fixed interval, while running speed remained roughly constant. Running depended on the fixed interval between shocks in the same way as bar-pressing maintained by food reinforcement, despite the fact that running was not established with nor maintained by explicit reinforcement. 相似文献
