采用移动窗口技术探讨读者在记叙文阅读中是否对人物第一印象进行即时更新。实验1探讨读者在阅读过程中是否会根据第一印象建构人物特征情境模型。实验2探讨已经形成的人物特征情境模型是否会受最近印象的影响得以更新。实验3探讨在明确描述人物特征的情况下,读者是否仍然会更新人物特征情境模型。研究结果表明,记叙文阅读中,读者会对人物第一印象进行即时更新,表现出首因效应向近因效应的转化。 相似文献

本研究采用建构主义教学评估问卷、认知压力问卷、一般元思维量表与情境元思维量表对381名学生进行测量,考察了建构主义教学与元思维之间的关系,以及一级、二级认知压力在其中的中介或解释作用。研究采用结构方程模型分析,结果显示:(1)仅考虑一级认知压力时,建构主义教学能正向预测两种元思维,一级认知压力在建构主义教学与两种元思维间皆起部分中介作用;(2)仅考虑二级认知压力时,其在建构主义教学与两种元思维间皆起完全中介作用;(3)同时加入两种认知压力时,仅二级认知压力的中介作用显著。 相似文献

Errors made by young children when they are asked to draw a model were investigated in two studies. In the first study, the experimenter asked 5- and 8-year-old children to draw a cup that had a flower decal (transfer) attached to its outside surface, attached to its inside surface or positioned beside it. The 8-year-old children in all conditions produced visually accurate drawings. The 5-year-old children produced visually accurate drawings when the flower decal was positioned beside the cup and when the flower decal was attached to the inside surface of the cup but not when the flower decal was attached to the cup's outside surface. In the second study, 5- and 8-year-old children were asked to draw a cup that had either an intact or a broken handle. The handle area of the cup was either in view or not in view. The 5- and 8-year-old children performed comparably in this experiment. The children had difficulty producing accurate copies of the model only when the cup had a handle and the handle was not in view. Taken together, these studies indicate that 5-year-old children are more likely to produce visually accurate drawings than has previously been supposed. Difficulty in producing accurate drawings occurred when drawing rules and drawing conventions interfered with the task. 相似文献

Four pigeons were trained on eight or nine pairs of independent concurrent variable-interval schedules. The range of reinforcement ratios included extreme ratios (up to 532 to 1). Large samples of stable performance were gathered. Contrary to the findings of Davison and Jones (1995), the generalized matching law described choice more accurately than a contingency-discriminability model. Taking small samples (5 to 10 sessions) and applying a more liberal stability criterion used by Davison and Jones only increased the unsystematic variance in the data and in estimates of generalized-matching-law sensitivity. Because changing to dependent scheduling and inserting a changeover delay had no systematic effect, the deviations from generalized matching reported by Davison and Jones probably arose from imperfectly discriminated stimuli. Analysis of visits revealed that visits to the nonpreferred alternative were brief and approximately constant. When choice between the preferred (rich) and nonpreferred (lean) alternatives, regardless of position, was analyzed according to the generalized matching law, sensitivities approximated 1.0, with bias in favor of the lean alternative. This bias, which arose from an excessive frequency of visits to the lean alternative, explains undermatching as the result of fitting one line to a choice relation that consists of two displaced lines, both with a slope of 1.0. The pattern of deviation from the generalized matching line confirmed this account. The findings suggest an alternative analysis of choice that focuses on probability of visiting the lean alternative as the dependent variable. This probability was directly proportional to ratio of reinforcement. Matching, undermatching, and overmatching may all be explained by a view of concurrent performance based on foraging theory, in which responding occurs primarily at the rich alternative and is occasionally interrupted by brief visits to the lean alternative. 相似文献

Contrary to previous findings documenting the importance of higher-order need satisfaction, a recent study by G. J. Gorn and R. N. Kanungo (Organizational Behavior and Human Performance, 1980, 26, 265–277) has indicated that satisfaction of lower-order needs may lead to job involvement if such needs are salient. Data from a heterogeneous sample of 632 employees from six organizations were used to test six hypotheses concerning the effects of need level (higher vs lower order) and need salience as moderators of the relationship between need satisfaction and alienation-involvement. Three different ways of operationalizing need saliency were used, including a replication of Gorn and Kanungo's procedure. Higherorder need satisfaction was correlated with alienation-involvement scores to a significantly greater degree than was lower-order need satisfaction, even for those for whom lower-order needs were most salient. Need saliency was not found to moderate the need satisfaction-involvement relationship when need level was controlled. Issues regarding the operationalization of “need salience” were discussed and a new measure of alienation-involvement (the A-I Scale) was introduced. Implications for further empirical investigations of the need saliency issue were noted, as was the universal application of job enrichment programs aimed at promoting higher-order need satisfaction. 相似文献

The general hypothesis that students self-selecting themselves for different occupational fields differ in relevant values and interests was tested for specializations within engineering. Industrial engineers were found to be different in work values and in their image of their subfield from students of other engineering specializations. The study concludes that in terms of type of student selecting engineering, the profession cannot be treated as an undifferentiated entity. It is suggested that in future research engineering students may be regarded as relatively homogenous with respect to work values only if their area of specialization is duly considered. 相似文献

First and second graders (6- and 7-year-olds) practiced reading 20 words. Before and after word training, they named pictures printed with and without these words as distractors. Of interest was whether training would enhance or diminish the interference created by these words in the picture-naming task. Results indicated that children who learned to recognize unfamiliar distractor words more accurately suffered more interference after training. In contrast, children who were already familiar with the words and learned to recognize them faster experienced less interference following training. Results are interpreted as supporting LaBerge and Samuels' model of automatic word processing. Effects of accuracy training are attributed to the elimination of attention as a requirement for processing distractor words. Effects of speed training are attributed to a reduction in the time consumed by distractor words in the central processor. 相似文献

Children from five to eight years of age learned to discriminate between mirrorimage oblique lines more readily when cards bearing the obliques were presented vertically than when they were presented horizontally. The difference in performance between the vertical and horizontal planes could not be accounted for by differences in either the external visual context or the availability of asymmetrical body information (e.g., left vs right hand). The superiority of the vertical plane was attributed to the congruence of objective, bodily, and retinal vertical axes for the vertical, but not the horizontal plane, It was concluded, on this basis, that at least part of children's difficulty discriminating between mirror-image obliques is due to their difficulty establishing the internalized vertical axis necessary for the left-right spatial coding of the obliques. 相似文献
