By around the age of 4 years, children acknowledge that people can have false beliefs about the world. Six-year-olds are still inclined, however, to confuse their own knowledge with that of more ignorant others. In a recent paper, Hulme, Mitchell and Wood offer a novel explanation for six-year-olds' tendency to make such errors when asked to choose a picture to put in a story character's thought bubble. 相似文献

This study investigated the long-term effects of using coloured filters on the frequency and type of errors in oral reading. A double-masked, placebo-controlled crossover experimental design was used, with subjects being assessed over a period of 20 months. There were three experimental groups (Placebo tints, Blue tints, and Diagnosed tints) involving 113 subjects with reading difficulties, ranging in age from 9.2 yr. to 13.1 yr. The 35 controls (ranging in age from 9.4 yr. to 12.9 yr.) had reading difficulties but did not require coloured filters. There was a significant improvement for all groups in the accuracy of miscues over the period, although experimental groups over-all did not improve at a significantly different rate than the control group. The failure to find significantly greater improvement for the experimental groups over the control group for the total period, despite subjects' reports of improved print clarity, may be partly related to the lack of effective letter-sound analysis and synthesis skills and to the use of a word-identification strategy of guessing based on partial visual analysis. 相似文献

Faculty and chairpersons (N = 102) at 34 programs granting doctoral degrees in health education were asked to rate the quality of professional journals related to health education. The American Journal of Public Health was the highest rated journal. Health Education Quarterly was second, and Health Education Research, the only other health education journal, was rated in the top 10 (rated 7). The journals from the epidemiology area rated higher than journals from other areas. The respondents were least familiar with journals on the environment, safety, and death education. 相似文献

We wished to identify predictors of family functioning from models including perceptions of stresses associated with mobility, financial compensation, intrusiveness to family boundaries, expectations on time demands, and the lack of social support. Data were collected from 136 randomly selected couples from six denominations in which husbands were clergy. Participants completed a survey that included the Clergy Family Life Inventory which assessed perceptions of five work-related stressors and the Self Report Measure of Family Functioning scale which measured 12 dimensions of family functioning. Separate regression models were tested for husbands and wives and these analyses indicated that no single stressor seemed influential for all 12 dimensions of family functioning. However, for both husbands and wives, family boundary intrusiveness, lack of social support, and mobility stresses influenced their competence in numerous areas of family functioning. In addition, husbands and wives experienced similar effects of stress among several dimensions of family functioning (e.g. enmeshment, family organization, democratic family atmosphere expressiveness). 相似文献

Using a BAB design, a token system requiring cooperative interaction was used to change the reading and vocabulary performance of an 18-member class of third-grade hyperactive boys. Four different colored tokens, which could be exchanged for 15 minutes of play on electrovideo games, were earned by successful completion of two tasks that involved learning to read and to use new vocabulary words in sentences, and two tasks in which the student served as a proctor to a student who had not yet completed those tasks. The mean number of tasks completed during the intervention periods rose to over nine times the number completed during reversal. Additionally, the average completion rate for the school district's standardized weekly reading level examinations rose from four to eight fold during the token conditions. All 18 students responded to the token program by increasing their academic performance. 相似文献

Tested the hypothesis that explicit identification of message ambiguity as a reason for failure in referential communication could help young children to gain understanding about the need for unique reference in communicative acts, in both experimental and natural settings. In the experiment each of 47 children aged 5-2 to 6-5 selected and then described clothes for a doll so that the experimenter could choose matching items. Ambiguous instructions from the children were consistently responded to with one of three reactions by the experimenter: (1) she guessed an item, (2) she asked ‘Which one?’ waited and chose or (3) she made explicit why she could not make a unique choice on the basis of the child's message. Both before and after this manipulation children were assessed for their understanding that messages can be ambiguous and can cause communication failure. Children accorded the third treatment improved most both in understanding and in reducing the ambiguity of their messages. A similar assessment of understanding was made of 36 6-year-old children of whom recordings of interaction in the home had been made over several previous years. Children whose mothers had made explicit their lack of understanding of their child's utterances were more advanced than those whose mothers had not. 相似文献

This paper presents a simple random procedure for selecting subsets of stimulus pairs for presentation to subjects. The resulting set of ratings from the group of subjects allows the construction of a group (average) space through the use of the computer program TORSCA-9 or equivalent programs. The procedure is applied to both real and simulated data. It is found that subjects need only make between 20% and 50% of the usual judgements to reconstruct a reasonably accurate group space. 相似文献
