Rural economically deprived adolescent males, who had been previously surveyed as high school seniors concerning their post-high school plans, were surveyed again 1 yr later concerning their present occupational status and feelings of personal satisfaction. The Ss had been divided in an earlier study into two groups, low identification males (LIM) and high identification males (HIM) based upon independent evaluators' judgments of the adequacy of their fathers as identification models. Each group's responses to the survey were compared. The results indicate that there are no statistically significant differences between the two groups on the variables of satisfaction, having received counseling from others and optimism about the future. There are statistically significant differences between the current occupational status and future occupational plans of the two groups. 相似文献

This study examined the effects of early identification and psychological services on underachievement through a follow-up study conducted six years later. One hundred and seventeen fourth-grade underachievers had been identified through a regression equation and were divided into experimental and control groups. The experimental group received psychological services during their fourth, fifth, and sixth grades from a team of university professors. Psychological services were primarily adult centered, focusing on the redirection of parents and teachers who were the primary influence on the lives of these underachievers. Follow-up studies of them at high school graduation indicated that differences between these groups reached at least the .05 level of significance for class rank, the ACT composite, the ITED composite and its subtests, and level of educational and vocational performance after high school graduation. Differences which were not statistically significant were found for pregraduation aspirations for the immediate future. 相似文献

Single-session crisis services by paraprofessionals (graduate students and community volunteers) in the emergency room of a community hospital were offered to 293 clients. These clients were followed-up 6 to 12 months after their last contact and asked about: (1) the effectiveness of the service, (2) their use of referrals, (3) the major source of change in their crisis situation, and (4) their rating of improvement for their presenting problem. There were 104 clients who completed the follow-up. The results support the interpretation that timely intervention by paraprofessionals may have long-lasting results in specific problem areas. A model emphasizing the use of service deliverers as researchers is proposed. 相似文献

Rhesus monkeys were given 960 delayed response (DR) problems. The incentive was either visible or not visible during the baiting phase of each problem, and a 0-, 5-, 10-, or 20-sec intraproblem delay was imposed. Performance was substantially better when the incentive could be seen during the baiting phase. When the incentive was visible during baiting, at all stages of training performance decreased as a function of increased chance levels after short delays, and the rate of improvement with training was comparable after each of the four intraproblem delays. When the incentive was not visible during the baiting phase, an inverse relationship between performance and delay duration became evident only during the later stages of training. On the initial problems performance was at chance levels, and although improvement with training was evident, the rate of this improvement was inversely related to delay duration. The findings were interpreted in terms of Fletcher's orienting response analysis of DR performance. 相似文献
