Methods of increasing learning efficiency through a blocking technique were examined in young children. An experimental group of children was trained on an initial task with one relevant dimension, followed by redundancy training in which an incidental dimension also became relevant. A control group given only redundancy training was compared to this group to test how much the experimental subjects blocked or screened out the incidental dimension. In order to increase blocking, three methods were used: a preset transfer problem, an overtraining on the initial task, and a delay following training. The most important finding was increased blocking through the Preset Condition. Overtraining and Delay Conditions had no effect. In addition, more slow learners on the initial task learned about the incidental dimension than fast or intermediate learners. Also, fewer subjects given form on the initial task learned about the incidental dimension than those given color. The Combined Blocking, Delay, and Overtraining group showed partial blocking, while the Preset group demonstrated complete blocking. No developmental differences occurred. The results were interpreted using a modification of Trabasso and Bower's attention model (Attention in learning: Theory and research. New York: Wiley, 1968).  相似文献

This paper extends investigation of religiosity and longevity to Taiwan using a 1989 survey: N = 3849, aged 60+, with 18 years of follow-up. Religious activity is measured as worship and performance of rituals. A Gompertz regression, adjusted and non-adjusted for covariates and mediating factors, shows the hazard of dying is lower for the religiously active versus the non-active. Transformed into life table functions, a 60-year-old religiously active Taiwanese female lives more than 1 year longer than her non-religious counterpart, ceteris paribus. Mainland Chinese migrants are examined carefully because of unique religious and health characteristics. They live longer, but the religiosity gap is similar.

In his article “It's a Wonderful Life,” Ronald Hall connects Wittgenstein's last words with Frank Capra's 1946 film. His analysis focuses on the concept of wonder, but he misses one of the most important aspects of both the film and Wittgenstein's last words: the significance of friendship. This is philosophically (and biographically) important because it raises questions about aspect‐seeing, friendship and everyday life. Wittgenstein's final words provide a striking example of the philosophical complexity of his life and work.  相似文献

This paper describes the relations of psychological distress with 11 ecological factors (5 community, 4 family, and 2 individual) among 423 older urban adolescents who are predominantly people of color. Data were obtained by means of self-report via group-administered questionnaires given between 1994 and 1996; most scales are multi-item. There is wide variation in distress. There are very few statistically significant relationships between the ecological factors and distress, and those are negligible. Girls whose parents have less education and live in extended families have higher distress; family and individual domains are correlated .04 and .03 with distress and the community domain .00, so this ecological model accounts for a mere 7%, of the common total variance in distress.  相似文献

An effective approach to reducing recidivism is, first, to identify a youth's risk of reoffending and then to match the intensity of interventions to that risk level. This pre-post quasi-experimental, prospective study compared 247 (pre) with 217 (post) adjudicated youths to examine the implementation of the Structured Assessment of Violence Risk in Youth (SAVRY) and its effects on case management practices in Louisiana's Caddo parish probation office. The results indicated that placement rates dropped by 50%, use of maximum levels of supervision dropped by almost 30%, and use of community services decreased except for high-risk youths, but only after the SAVRY was properly implemented. This shift towards more appropriate allocation of resources that are matched to risk level occurred without a significant increase in reoffending. The implications for implementation and for use of risk/needs assessment in juvenile probation are discussed. Copyright ? 2012 John Wiley & Sons, Ltd.  相似文献

Satisfaction is an important patient reported outcome of genetic counseling, as it is one of the elements used by professional organizations and healthcare accrediting bodies to determine the quality of professional work. However, empirical research on patient satisfaction with genetic counseling has been limited, partly due to the lack of standardized measures available to assess this construct. The purpose of this study was to conduct a psychometric analysis of a new satisfaction measure, the Genetic Counseling Satisfaction Scale (GCSS), within a sample of women participating in a no-cost cancer genetic counseling and testing program. The sample consisted of 61 women undergoing counseling and testing for hereditary breast-ovarian cancer risk (BRCA1/2 testing) who completed the GCSS following pretest counseling. The results suggest that the GCSS was reliable (Cronbach's coefficient alpha = 0.90) and that participants were highly satisfied with the care they received. In addition, there were no differences in satisfaction between cancer genetic counseling and prenatal counseling participants (based on preexisting norms), and satisfaction did not vary by sociodemographic characteristics. Implications and recommendations are discussed.  相似文献
