Children's use ofget in passivelike constructions was examined in this study. Fifty-eight children at three age levels were tested twice on imitation, comprehension, and production tasks. For the imitation and comprehension tasks, passive sentences withget were modeled in one instance and withbe in the other instance. On both tasks, children performed significantly better on theget items than on thebe items. For the production tasks, active sentences were used as the experimental stimuli. Among 928 production responses possible, children produced 423get passives and 6be passives. The frequency ofget passives increased with increasing age. Qualitative analyses were performed to determine agerelated changes in the pattern of linguistic strategies chosen. These data were consistent with predictions derived from a model of lexical directionality: Children used moreget thanbe passives and more truncated than full passives.  相似文献

Young children can express conceptual difficulties with the appearance-reality distinction in two different ways: (1) by incorrectly reporting appearance when asked to report reality (“phenomenism”); (2) by incorrectly reporting reality when asked to report appearance (“intellectual realism”). Although both phenomenism errors and intellectual realism errors have been observed in previous studies of young children's cognition, the two have not been seen as conceptually related and only the former errors have been taken as a symptom of difficulties with the appearance-reality distinction. Three experiments investigated 3- to 5-year-old children's ability to distinguish between and correctly identify real versus apparent object properties (color, size, and shape), object identities, object presence-absence, and action identities. Even the 3-year-olds appeared to have some ability to make correct appearance-reality discriminations and this ability increased with age. Errors were frequent, however, and almost all children who erred made both kinds. Phenomenism errors predominated on tasks where the appearance versus reality of the three object properties were in question; intellectual realism errors predominated on the other three types of tasks. Possible reasons for this curious error pattern were advanced. It was also suggested that young children's problems with the appearance-reality distinction may be partly due to a specific metacognitive limitation, namely, a difficulty in analyzing the nature and source of their own mental representations.  相似文献

Where We Go With a Little Good Information   总被引:1,自引:0,他引:1  
Abstract—When observers move through an environment, they are immersed in a sea of motions that guide their further movements. The horizontal relative motions of all possible pairs of stationary objects fall into three classes: They converge, diverge and slow down, or diverge with increasing velocity. Conjoined with ordinal depth information, the first two motions reveal nominal invariants, constraining heading to one side of the visual field. When two object pairs yield invariants on opposing sides of the heading, they can constrain judgments to a narrow region. Distributional analyses of responses in an experiment involving simulated observer movement suggest that observers follow these constraints.  相似文献

This study explored whether mid-life women regard hot flushes at work as a substantial stressor. A sample of 29 working women reporting hot flushes for at least 12 months rated the degree to which each of ten work situations influenced flush distress or discomfort. Ratings were compared with qualitative accounts of coping with flushes at work. Results showed that women differed markedly in the work situations that they regarded as most problematic, but flush distress was commonly magnified during formal meetings, in hot enclosed spaces and in the presence of male colleagues. A substantial minority viewed colleagues as conveying negative attitudes towards menopausal problems, which jeopardised general confidence at work as well as creating specific difficulties during frush episodes. Flush distress was higher among those reporting embarrassment and dificulties disclosing menopausal status to others. Respondents made suggestions for ways in which the working environment could be improved to assist women in managing hot flushes. Coping with flushes was largely seen as an individual rather than organisational responsibility. Other stigmatising health problems may present similar subjective problems at work, and this needs further study. Some implications for counsellors working in organisational settings are explored.  相似文献

Two factors were investigated in terms of their effects on information seeking about ethnic groups: degree to which the information confirmed one's stereotype, and motivation for seeking information. Forty-two English Canadians (Ss) were given the opportunity to seek up to 45 items of information about 18 individuals, 3 from each of six ethnic groups. The three members of each group either confirmed, partially disconfirmed, or totally disconfirmed the group stereotype. Results indicated that more information was sought about the confirming member of each group by the Ss instructed to seek information that interested them. Ss instructed to describe or evaluate ethnic group members sought information equally from all members. These results are discussed in terms of expectancy theory, and in relation to other findings on ethnic perception and ethnic interpersonal attraction.  相似文献

This study is concerned with recent claims that subjective measures of word frequency are more suitable than are standard word frequency counts as indices of actual frequency of word encounter. A multiple regression study is reported, which shows that the major predictor of familiarity ratings is word learning age. Objective measures of spoken and written word frequency made independent contributions to the variance. It is concluded that rated familiarity is not an appropriate substitute for objective frequency measures. A multiple regression study of word naming latency is reported, and shows that rated word learning age is a better predictor of word naming latency than are spoken word frequency, written word frequency, rated familiarity, and other variables. Possible theoretical explanations for age-of-acquisition effects are discussed and it is concluded that early-learned words have a more complete representation in a phonological output lexicon. This conclusion is related to relevant developmental literature.  相似文献
