A series of experiments is reported on the stimulus suffix effect with the primary variables being age of the subject (7 and 11 years), rate of presentation, and list length. While the suffix effect was larger for younger subjects at a slow rate of presentation, the effect was nearly identical across age groups with a fast presentation rate. It was concluded that when the contaminating effects of more central processes are reduced, there is no developmental change in the capacity of echoic memory. An interesting effect of rate of presentation is reported with younger subjects performing better at faster rates of presentation and adults performing better at slower rates. 相似文献

Research is reported which looks at the possibility of using attitude measures to identify, before they leave school, those low-attaining pupils at risk of longer periods of unemployment, and therefore in particular need of support, information and skills. Two independent assessments of attitudes were used: ratings by class teachers, and attitude scales. Findings were largely negative: we cannot predict, through the use of attitude measures alone, which pupils will take longest to find jobs. A variety of other factors influencing duration of unemployment are discussed, together with some implications for careers teaching in schools. 相似文献

This article discusses the clinical training of group therapists, the conditions under which students function as cotherapists, and the ways in which having a student trainee as cotherapist to an experienced group therapist can enhance or facilitate the therapeutic process for group members. Such enhancement can be brought about directly by: stimulating the emergence of new material; providing different perspectives and different reactions; providing different models; bringing out different transferences; affecting the working alliances; and requiring patients to deal with the loss of the cotherapist. It is brought about indirectly by: each therapist picking up on the blind spots or distortions of the other; each perceiving and discussing in supervisory conferences the other's countertransferences; and using weekly supervisory conferences to develop an increasingly cooperative relationship. 相似文献

Consider an old testX consisting ofs sections and two new testsY andZ similar toX consisting ofp andq sections respectively. All subjects are given testX plus two variable sections from either testY orZ. Different pairings of variable sections are given to each subsample of subjects. We present a method of estimating the covariance matrix of the combined test (X

) and describe an application of these estimation techniques to linear, observed-score, test equating.The author is indebted to Paul W. Holland and Donald B.

Early lexical development in children with focal brain injury 总被引:4,自引:0,他引:4

Early lexical development in 27 children with focal brain injury was studied cross-sectionally and longitudinally. Data were obtained from children between 12 and 35 months of age who acquired their lesion prenatally or within the first 6 months of life. Results for the group as a whole provide clear evidence for delays in lexical comprehension and production, and for a larger number of comprehension/production dissociations than would be expected by chance. In addition, a significant number of children were observed having unusual difficulty mastering predication and/or using an atypically high proportion of closed class words (suggesting reliance on holistic/formulaic speech). Analyses by lesion type revealed no effect of lesion size. Analyses according to side of lesion revealed that children with right-hemisphere damage produced a higher proportion of closed class words, suggesting heavy reliance on well-practiced but under-analyzed speech formulae. Children with left-hemisphere damage were slightly better in comprehension than children with right-hemisphere damage. In addition, left posterior lesions were associated with greater delays in expressive language, and delays were more protracted in children with left posterior damage. No differential effects of left posterior damage were found for lexical comprehension. 相似文献

Twelve children with early intense reading and superior word recognition skills coupled with disordered language and cognitive behavior are described. Cognitive, linguistic, and reading measures evidenced a generalized cognitive deficit in forming superordinate schemata which was not specific to visual or auditory modalities. Positive family histories for reading problems were present for 11 of the 12 children, suggesting a relationship between hyperlexia and dyslexia. 相似文献

Normal language development was studied in 310 pairs of 4-year-old twins born in the United Kingdom in 1994. Twins were assessed individually in their homes on a diverse battery of language and nonverbal measures. Rotated factor analyses indicated the presence of a general Language factor (L) as well as a general Nonverbal (NV) factor. Moderate genetic influence was found for both L and NV abilities. Bivariate genetic analysis estimated a genetic correlation of .63 between L and NV abilities, implying that over half of the genetic influence on L overlaps with genetic influence on NV. These results suggest that at age 4, genetic influences on individual differences in language overlap substantially with genetic influences on individual differences in other cognitive abilities, although perhaps less so than later in development. 相似文献

Cotton-top tamarins (Saguinus oedipus) selected canes positioned so that a straight inward pull brought food within reach (M. D. Hauser, 1997; see also record 1997-41347-003). Tamarins failed to retrieve food with canes in other positions, and they did not reposition these canes. In this study, tufted capuchin monkeys (Cebus apella) preferred canes they could pull straight in when these were present, but they also repositioned canes in individually variable ways, and their success at obtaining food with repositioned canes improved with practice. In accord with predictions drawn from ecological psychology, capuchins discovered affordances of canes through exploratory actions with these objects, whereas tamarins did not. Ecological theory predicts these differences on the basis of species-typical manipulative activity, and it provides a useful approach for the study of species differences in tool-using behavior. 相似文献
