College students read short texts from a cathode-ray tube as their eye movements were being monitored. During selected fixations, the text was briefly masked and then it reappeared with one word changed. Subjects often were unaware that the word had changed. Sometimes they reported seeing the first presented word, sometimes the second presented word, and sometimes both. When only one word was reported, two factors were found to determine which one it was: the length of time a word was present during the fixation and the predictability of a word in its context. The results suggested that visual information is utilized for reading at a crucial period during the fixation and that this crucial period can occur at different times on different fixations. The pattern of responses suggested that the first letter of a word is not utilized before other letters and that letters are not scanned from left to right during a fixation. 相似文献

When people are asked to recall words from a list they have just studied or to produce as many items as possible from a well-known category (e.g., states of the United States), having available a subset of the items as cues often does not facilitate retrieval of the remaining items and sometimes inhibits it. The finding has been obtained many times with a variety of experimental tasks including recall from categorized and noncategorized lists and retrieval from very long-term memory. This paper reviews the studies that have yielded the effect, and considers several explanations of it that have been proposed. None of these explanations is viewed to be entirely adequate and compelling. 相似文献

This study assessed 13 aphasic subjects' knowledge of the multiple meanings of homographs. The results indicated that the various meanings were less available to aphasic subjects than to normal subjects. In addition, specific meanings became less available as they became less typical although the number of meanings associated with a homograph did not influence performance. Aphasia type also did not influence performance. Performance on the experimental test was significantly correlated with auditory comprehension level and picture naming ability. The results were related to recent findings on semantic organization in aphasia. 相似文献

The major theories and research approaches as to the etiology and development of stuttering are reviewed from a historical perspective. Findings are drawn from different sources indicating that language deficits are an initial contributing factor and a continuing component of this disorder. Those subsets of children which constitute high-risk groups are identified. It is suggested that researchers begin investigating the underlying organic bases of stuttering and its relationship to stages of language development. Finally, clinicians are encouraged to employ a therapy program that is concerned with all areas of language, rather than emphasizing treating only the symptoms of stuttering behavior. 相似文献

This study is concerned with the commonalities inherent in diverse psychotherapeutic strategies, despite seemingly discontinuous theoretical stances. Two approaches were evaluated with respect to effective family functioning, viz. Analytical Psychology and Systems Theory. Analytical Psychology posits the growth of conscious awareness in the individual as the source of therapeutic change. Problem centred systems therapy of the family emphasizes the importance of teaching clinically presenting families to negotiate collectively family rules and expectations and thus to allocate and monitor roles via clear and direct verbal communication. Both positions thus stress the reflective mode as a pivotal factor in effective problem solving. Analytical psychology maintains that conscious awareness expands to the extent that the individual integrates the contrasexual aspect of the personality, that is, the affective, expressive mode or 'feminine principle' in the male, or the instrumental, assertive 'masculine principle' in the female. Such individuals are said to be 'androgenous'. It was therefore hypothesized that such individuals would more readily be able to negotiate family rules and expectations in a manner consistent with a major therapeutic thrust of family therapy. These clinically derived hypotheses were subjected to an empirical test by assessing twenty, non-clinical, dual-career families where both parents pursued careers and were therefore presumably both required to share instrumental and affective roles on the basis of mutual agreement. Results indicated that negotiation contributed significantly to successful role fulfilment and effective family functioning, thus substantiating the focus of family therapy strategies upon clear and direct communication and role allocation. 相似文献

Three papers (V. A. Mann, Reading skill and language skill. Developmental Review, 1984, 4, 1–15; G. Wolford & C. A. Fowler, Differential use of partial information by good and poor readers. Developmental Review, 1984, 4, 16–35; F. J. Morrison, Reading disability: A problem in rule learning and word decoding. Developmental Review, 1984, 4, 36–47) are critiqued from the standpoint of their adequacy in advancing our understanding of a problem as complex as reading disability. Experimenters should be explicit about their guiding theoretical assumptions, and should think through the relations, if any, between their laboratory tasks and the actual processes of reading. The reading protocol of a dyslexic child is provided, and is interpreted within the frameworks of the Mann, Wolford and Fowler, and Morrison viewpoints. 相似文献

First-grade children were given either empathy instructions (in which they were told to imagine themselves in the target person's place) or neutral instructions (in which they were told to listen to what the target person did). For half the subjects, the target person was of the same sex; for the other half, the target person was of the opposite sex. Subjects were then given a chance to anonymously donate money to the target child, who was presented as being in need. Liking for the target child, subject's perceptions of the target child's emotional state, and subjects' report of their own emotional states were also assessed. Empathic instructions increased donating behavior for males, but not for females. Accuracy of perception of the target person's state was generally high. Self-reports of emotional states congruent with that of the target tended to be associated with increased donating behavior only for males, but these self-reports were greater for females than males, and greater for both sexes with same-sex target persons. Liking also was enhanced by gender similarity. These results are discussed in terms of a proposed relationship among empathy, prosocial behavior, sex, and age.We wish to express our gratitude to the staff and students of Wannamaker and North Fairview Elementary Schools of Topeka, Kansas, for their assistance in carrying out this research, and also thank C. Daniel Batson for his helpful suggestions and comments. 相似文献
