Written and oral spelling were compared in 33 patients with Alzheimer's disease (AD) and 25 control subjects. AD patients had poorer spelling results which were influenced by orthographic difficulty and word frequency, but not by grammatical word class. Lexical spelling was also more deteriorated than phonological spelling. Moreover, oral spelling was more impaired than written spelling in AD patients, whereas no difference was present between oral and written spelling of controls. Analysis of spelling errors showed that, for controls, errors were predominantly phonologically accurate in both spelling tasks. Significantly, AD patients produced more phonologically accurate than inaccurate errors in written spelling, whereas these errors did not differ in oral spelling. In contrast to controls who produced more constant than variable responses in oral and written spelling, AD patients made more variable responses (words correctly spelled in one task but incorrectly in the other) and they showed many instances of variable errors (different misspellings from one spelling task to the other). Two stepwise regression procedures showed that written misspellings were specifically correlated with language impairment, whereas oral spelling errors were correlated with attentional and language disorders. These results suggest that AD increases the attentional demands of oral spelling process as compared to written spelling. This dissociation argues, either for a unique Graphemic Buffer in which oral spelling requires more attentional resources than written spelling or for the hypothesis of separate buffers for oral and written spelling. 相似文献

This report summarizes the results of a nearly day-long session of a group of experienced and distinguished family therapy practitioners and researchers. The task the group set for itself was to begin delineating the most important variables to attend to in understanding family therapy and evaluating its effectiveness. With full recognition that such a task could be only partially and tentatively accomplished in the time allotted, a great many such variables were outlined. 相似文献

Sutherland (1961) proposed that the detection of motion might depend upon the ratios of firings in cells sensitive to movement in opposite directions. Sekuler and his collaborators have argued that the notion of a ratio mechanism at threshold is wrong. The findings and arguments upon which this conclusion was based are challenged, an explicit model is described which provides an account of data previously held to be inconsistent with a ratio model, and an experiment is reported which provides unequivocal support for the ratio model and whose findings are inconsistent with the predictions from Sekuler's “independence” model. 相似文献

The effects of influence attempts by a majority and by a minority were examined on both a manifest response level and a latent perceptual level. Female subjects were exposed to a series of blue slides that were consistently labeled as green by a female confederate. The confederate was presented as a member of either a majority or a minority. On each trial, subjects were required to indicate the color of the slide presented and the color of the afterimage perceived on a white screen following removal of the slide. It was predicted that (a) the subject's judgment of the chromatic afterimage would be modified when the influence agent represented a minority, and (b) this modification will be more pronounced when the source of influence is absent than when it is present. The results supported the prediction in both the main study and its replication. 相似文献

This research examined the influence of task difficulty and diagnosticity (ability information) on task choice and preference. It was found that males preferred diagnostic over non-diagnostic tasks, but among females significant preferences along this variable were not exhibited. Furthermore, the desire to obtain ability-relevant information decreased as a function of prior knowledge about one's ability. Both high and low ability self-perceptions, induced through prior experiences of success and failure, decreased the attraction toward diagnostic in formation. There was no indication that individuals with high ability self-concepts are especially avoidant of further ability-relevant information, as recent literature has suggested. In addition, and contrary to prior findings, difficult tasks were most preferred rather than easy or intermediate tasks, given that diagnosticity is held constant. 相似文献

The research literature was examined with regard to relationships between Field-dependence and Extraversion. Eysenck's contention that the two variables are significantly related to an extent justifying the use of causal hypotheses based on extraversion theory to account for field-dependent behavior was not supported. 相似文献
