Two children with an acquired aphasia were observed during the recovery process. In the spontaneous speech, paraphasias belonging to different categories, such as neologisms, verbal paraphasias, and literal paraphasias, were found. Especially with regard to neologisms the time of investigation was very important. In addition, one child with a phonemic jargon aphasia and one child with a fluent aphasia and empty speech were observed. These observations implicate a modification of the current clinical picture of childhood aphasia. Some aspects are discussed in relation to adult aphasia. 相似文献

Two experiments investigated whether disposition-based categories influence the retrieval of behaviors related or unrelated to those categories. In Experiment 1, subjects studied a set of behaviors in order to form an impression of a target person. Impression ratings indicated which category had been activated. In an unexpected recognition test, accuracy was better for category-inconsistent information than for category-consistent behaviors. That result suggested that the structure of disposition-based categories includes qualitatively different representations of consistent and inconsistent acts related to the category. In Experiment 2, subjects rated behaviors with reference to a relevant or irrelevant disposition category. In an unexpected recall test, an advantage for category-inconsistent behaviors was found only when the behaviors had been studied from the perspective of the relevant category. It was concluded that categories are not represented in a form analogous to the representation of category-inconsistent behaviors. 相似文献

Previous findings of a developmental trend from holistic to analytic modes of processing yield to two possible interpretations—the ability to analyze into dimensions increases with age, or a production deficiency for the strategy of analyzing decreases with age. In the three studies reported here an attempt is made to elucidate which of these interpretations is the more correct by investigating the performance of preschoolers and retarded children in three tasks, all of which require dimensional analysis. The three tasks involve (a) same-different comparisons of selected dimensions of stimuli, (b) judgments of whether dimensions are conserved through transformations of objects, and (c) predictions of the outcomes of transformations that selectively modify dimensions of objects. Normal 3-year-old children and mildly retarded preadolescents make many errors on all three tasks and the patterns of these errors are predictable from holistic processing. Older groups of normal preschoolers, 4.5 to 5 years old, perform very well on the tasks, although they show some hints of remaining analytic deficits. It seems likely that the ability to analyze does undergo development in the preschool years, but that the production-deficiency interpretation also has merit, particularly for explaining developmental trends within the elementary school range. 相似文献

In this investigation the ability of stutterers and nonstutterers to simultaneously perform speech and nonspeech tasks was compared. Subjects were 10 stutterers and 10 nonstutterers. Two experiments were conducted. In the first, subjects performed a non-attention-demanding gross-motor task while they read aloud. In the second, subjects performed an attention-demanding task (reading comprehension) during speech. Results indicated that there was no significant change in the disfluency values of stutterers during the motor activity or as a result of the reading comprehension task. However, stutterers were found to perform significantly poorer than nonstutterers on the reading comprehension task. This finding was taken as evidence that stutterers devote more attention to speech than do nonstutterers. 相似文献

An analysis of the concurrent incidence of aphasia and spatial disorder in 270 patients with unilateral brain damage suggests that the two functions are statistically independent. These data can also be used to estimate the distribution of left, right, and bilateral representation of linguistic and spatial functions in the population. In right-handers, sex affects the pattern of cerebral asymmetries, while the familial history of sinistrality has a stronger effect on the pattern of cerebral asymmetries in left-handers. These findings suggest that complementary specialization exists only as a statistical norm: It is suggested that differences in complementary and noncomplementary specialization may underlie individual differences in cognitive skills. 相似文献

The race-IQ controversy arose at a time when psychometric views of intelligence dominated. Little attention was paid to more process-oriented models in spite of the fact they provide alternative perspectives on the causes of individual differences in problem-solving. We hypothesized that much of the IQ spread commonly observed between black and white children can be attributed to differences in components of their executive systems, including the knowledge base, control processes, and metacognitive states. To test this possibility, black and white children who differed significantly on fluid and crystallized intelligence were tested on multiple tasks reflecting components of the executive systems as well as on perceptual efficiency tasks. Striking group differences were observed in metamemory, stragegy use, and general knowledge, but few reliable differences were found in perceptual efficiency. Regression analyses showed that different factors predicted fluid and crystallized intelligence, with metamemory predicting the latter but not the former. An implication of these findings has potential educational significance: training directed at executive skills, introduce at an early age, might elevate learning and problem-solving skills in black children, thereby reducing racial differences in crystallized intelligence. 相似文献

This study is a partial (omitting college students) replication of R. V. Kail and A. W. Siegel (Journal of Experimental Child Psychology, 1977, 23, 341–347) in Ghana and Scotland on boys and girls with 4 and 7 years of education. After viewing sets of five or seven letters in a 4 × 4 matrix they remembered either (a) the letters, (b) positions of the letters, or (c) both letters and positions. Contrary to the results of the original study, no sex difference in relative recall of letters and positions was found. There was also evidence that verbal and spatial information is not always processed independently. A prediction that Scottish children would have better recall of positions was supported. The discussion notes the limitations of intracultural research as a basis for generalizations. 相似文献

Third- and fourth-grade boys and girls (mean age 7 years, 10 months) were directly instructed to share half their winnings from a bowling game under one of three types of verbal appeal: a power assertive appeal emphasizing punitive consequences for noncompliance, an inductive appeal emphasizing the child's potential contribution to the well being of another person, or a neutral appeal. While they complied with this request, half the children were monitored by television camera; the other half were not. A measure of generalized sharing (noninstructed sharing under anonymous conditions) was then collected. It was predicted that generalized sharing would be greater for children who had heard the inductive appeal than for children who had heard the power assertive appeal and would be greater for children who had shared without television surveillance than for children who had shared under survellance. As predicted, generalized sharing was highest among children who had received the inductive appeal. However, prior surveillance depressed noninstructed sharing only for girls who had received the power assertive appeal. There was one additional and unexpected finding: when children were asked to reinforce themselves for having shared in the instructed sharing phase, boys who had shared in compliance with a power assertive appeal indulged themselves more than children in any other condition. 相似文献

Twenty-five hospitalized nonfluent, fluent, and global aphasic patients who were several months past the onset of their illness were compared for presence and severity of depression based on four psychopathological measures. The nonfluent aphasic patients had both greater frequency and severity of depression than the other two groups. CT scans showed that the global aphasic patients had the largest lesion size (volumetric) and showed a strong correlation between lesion size and degree of depression. In contrast, patients with fluent aphasias showed an inverse correlation between severity of depression and lesion size; among the nonfluent aphasic patients there was no significant correlation. Depression appears to be common in this population of hospitalized aphasic patients with chronic illness and nonfluent patients are the most depressed group within this population. The increased frequency and severity of depression in the nonfluent patients did not appear to be related to their overall physical or cognitive impairment; two possible mechanisms are discussed. 相似文献
