The authors present a short review of the pertinent literature and report on their own neuropsychiatric findings following internal craniocerebral injuries, at the same time drawing attention to the necessity of psychological examination. Statistical comparisons with the international literature are complicated owing to the different classifications used for craniocerebral injuries.  相似文献

Three psychotherapy groups consisting of altogether 37 patients took part in communication training after L. Sch?bisch and M. Sieme in preparation for group-centred dynamic psychotherapy. The results of pretherapy and post-therapy surveys with the MMPI were tested for quantitative changes using Posthoff and H. F. B?ttcher's gnoseologically based test. The findings suggest that this combination of methods has a high standard of efficiency, which is finally discussed.  相似文献

The role of visual memory in learning to spell words was investigated through a matching task on which one nonsense word was presented, then a second word identical in spelling or differing in one letter was presented. Ten pairs of 9th and 10th-grade students, matched for intelligence and sex but of different spelling ability, were asked to indicate whether word pairs were spelled the same or differently. The two words of a pair were either the same or different in print size or letter case. Significant effects were obtained for spelling ability, print size (same or different), and letter case (same or different), and the interaction of size X case, providing evidence for the use of visual memory by both good and poor spellers in learning to spell words. Good spellers were equally able to identify matched and mismatched pairs, while poor spellers showed greater difficulty in identifying mismatches than matches, supporting Frith's (1980) "partial cues" explanation of poor spelling performance.  相似文献

A follow-up study with a younger group of mildly handicapped Japanese students was conducted to determine if the correlations between the Developmental Test of Visual-motor Integration and reading and mathematics achievement would substantiate the previous findings. For 30 mildly handicapped 11- and 12-yr.-old Japanese students, visual-motor integration scores were significantly correlated with both mathematics and reading scores. These results, added to the 1984 Webb and Abe data, further support the test's cross-cultural validity.  相似文献

Hyperlexia and a variant of hypergraphia   总被引:1,自引:0,他引:1  
A patient with hyperlexia and hypergraphia is described. The unusual co-occurrence of these two abilities is discussed. Hyperlexia may provide a useful marker to guide educational programming.  相似文献

The purposes of this study were (1) to replicate a right visual-field advantage for a version of the Embedded Figures Test modified for tachistoscopic presentation and (2) to test for a relationship between field independence and performance on modified Embedded Figures Test items presented to the right visual-field. 34 right-handed subjects were presented Embedded Figures Test items to the left, center, and right visual-fields for 150 msec. The Group Embedded Figures Test was also given. Results showed a right visual-field advantage on the modified embedded-figures test and (2) a negative relationship between Group Embedded Figures Test performance and right visual-field scores. These findings were discussed in terms of the differences between the two versions of the embedded-figures test, memory for simple figures, specificity of judgment, and sustained versus tachistoscopic perception. A tentative conclusion suggests that a better internal representation of the briefly presented complex figures places field-independent subjects at a disadvantage on the modified version of the test.  相似文献
