This Basic Journal List of forty-eight journal titles is intended as a selection guide for the librarian of the small hospital. It is based on a survey of physicians in Virginia who were asked to review journal titles contained in the 1967 edition of a list compiled by Mr. Alfred N. Brandon. The List is designed for the library in a hospital of from 100 to 300 beds and for the active clinician.  相似文献

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.  相似文献

Previous research has found that children engage in Level 2 visual perspective-taking, that is, the understanding that others may see things in a different way, between 4 and 5 years of age (e.g., J. H. Flavell, B. A. Everett, K. Croft, & E. R. Flavell, 1981). This ability was reexamined in 36-month-olds using color filters. In Experiment 1 (N = 24), children had to recognize how an object looked to an adult when she saw it through a color filter. In Experiment 2 (N = 24), a novel production test was applied. Results of both studies show that 36-month-olds know how an object looks to another person. The discussion focuses on the psychological requirements of visual perspective-taking and its relation to other "theory of mind" abilities, such as the distinction between appearance and reality and understanding false belief.  相似文献

MEDLINE (MEDLARS-ON-LINE) is the new on-line, interactive bibliographic searching system which was recently developed by the National Library of Medicine. The system provides users with lists of bibliographical citations and other information from a three-year file of over 1,250 biomedical journals. A survey testing user reactions was conducted at the University of Virginia Medical Library. The results of the survey are based on replies by 246 users who requested one or more MEDLINE searches between September 1972 and March 1973. The findings indicate that over 93% believe that MEDLINE is a substantial improvement over the traditional methods of searching through the printed indexes. These respondents also stated that the results of MEDLINE searches had assisted them in their clinical or research work, or both. Asked whether they would continue to use MEDLINE after the imposition of user charges on July 1, 1973, about 75% said that they would. The remaining 25% expressed some reservations and doubts. The survey gives reason to believe that with the imposition of user charges the use of MEDLINE will decline.  相似文献

The study investigated if 2.5‐year‐olds are susceptible to suspense and express tension when others' false expectations are about to be disappointed. In two experiments (= 32 each), children showed more tension when a protagonist approached a box with a false belief about its content than when she was ignorant. In Experiment 2, children also expressed more tension when the protagonist's belief was false than when it was true. The findings reveal that toddlers affectively anticipate the “rude awakening” of an agent who is about to discover unexpected reality. They thus not only understand false beliefs per se but also grasp the affective implications of being mistaken. The results are discussed with recourse to current theories about early understanding of false beliefs.  相似文献

Abstract

This paper proposes an alternate model of Vygotsky's zone of proximal development. It is argued that conceptions of the «zone» emphasizing the transfer of skills from adult to child are too narrow, theoretically misleading, and of limited instructional utility. The concept is then examined in relation to Vygotsky's broader theoretical and practical concerns. Examples taken from a recent classroom observational study are provided to illustrate how the concept of the zone can facilitate a critical assessment of children and of the social system created for the children to learn. The focus is on the appropriation and mastery of mediational means, such as writing, assessed not only or necessarily through independent performance after guided practice, but by the ability of children to participate in qualitatively new collaborative activities. The role of the adult isn't to provide structured cues to facilitate performance, but through exploratory talk and other social mediations assist children in taking control of their own learning. The concern is not only with creating individual zones of proximal development, but collective, interrelated zones as part of a teaching system.  相似文献

Resumen

El presente articulo describe y justifica teóricamente una actividad educativa que induye el uso de microcomputadores a través de una comunicación telemática. Esta actividad consiste en la redacción de una revista bilingüe (inglés-español) en la que colaboran niños de diversas culturas. A través de esta actividad se trabajan temas como la «alfabetización informàtica», la composición de textos y los idiomas. Esta intervención educativa viene acompañada de un intercambio de información científica a través de una red académica de comunicaciones telemáticas para el intercambio de información científica. El marco teórico en el que se desarrolla este trabajo se deriva del de la psicología vygotskiana y de alguno de sus desarrollos posteriores.  相似文献
