Studies examining the relationship between sugar intake of hyperactive children and behavior problems have reported inconsistent results. We hypothesized that if the problem behaviors of attention deficit-disordered children with hyperactivity (ADDH) are exacerbated by food, then this might be due to differences in their background nutrition relative to non-ADDH children. Parents and day care workers of 24 ADDH and 27 non-ADDH preschoolaged boys were trained to keep food diaries for 21 days. Analysis of the last 14 days for each child revealed no differences in overall nutrient intake between the two groups. On the other hand, for 5 ADDH and 3 non-ADDH children the within-subject correlations between daily behavior and sugar intake were significant. We concluded that nutrition-behavior interactions are more likely a function of idiosyncratic sensitivities, rather than a general tendency for ADDH children to eat differently from non-ADDH children.This research was funded by the Alberta Mental Health Research Advisory Council, and by the National Health Research and Development Program of Health and Welfare Canada. We think Jeannine Fraser for help with data analyses. 相似文献

The hypothesis that the language disorder in Alzheimer's disease (AD) depends on degenerative brain changes in classical left-hemisphere language zones was tested by comparing the written language performances of a group of AD patients with mild-moderate dementia and left-hemisphere stroke patients with equally severe naming and auditory comprehension deficits who were in varying stages of recovery from Wernicke's aphasia. The results indicated significant qualitative group differences in performances between tasks and in errors within tasks. The findings are consistent with hypothesized disruption of more diffusely organized neurolinguistic systems in AD. The hypothesis that the language disorder in AD represents an exaggeration of the pattern of language change in normal aging was also examined by comparing the performances of AD patients to the changes that occur with very advanced normal aging. The data indicate convergence between AD and very elderly healthy subjects in some aspects of written language production. 相似文献

The neuropsychological assessments of a patient with language disturbance following left thalamic-putaminal hemorrhage over a period are presented together with premorbid measures of performance. Findings indicate that behavioral deficits which are both linguistic and nonlinguistic in nature differ from cortical aphasic syndromes in symptomatology and recovery course. The deficit pattern is also unlike that in other reported cases of left-subcortical lesions. Persistent dysarthria with fluent speech, limitation of verbal span and repetition, agraphia and anomia, and disturbances in self-regulation of behavior were noted, in addition to recovery of an initially severe auditory comprehension deficit. A distinguishing feature of this case was the relative preservation of reading comprehension in all four assessments. 相似文献

Twenty-two therapists who had treated 57 families in brief conjoint family therapy under supervision responded to a videotaped simulated family as if they were treating it. Their responses were audiotaped and coded on a system devised for this study. Positive relationships were found between the ratings of expertise based on the coding system, and independent ratings of the treated families' satisfaction with treatment and the status of the presenting symptoms 6 months after termination. Videotaped simulated families are potentially useful as standardizable methods of revealing individual differences in therapists for family therapy outcome research. 相似文献

It is fairly straightforward to write a small program for a small computer, even using a relatively slow and unstructured language such as BASIC. However, current experiments in psychopharmacology require the system integration and data management services provided by large programs running on 256K microcomputers, and the efficient development of such programs requires the use of structured languages such as Pascal. 相似文献

Three experiments examined the interactions of category structure and prior knowledge in category learning.Experiment 1 examined the distribution of atypical or 'crossover' features in category learning. In real categories, crossover features may be unevenly distributed found primarily in very unusual examples of a category (like whales or ostriches). In contrast, in many psychology experiments, each item has exactly one crossover feature. Even versus uneven distribution of crossover features did not affect category learning when the features were neutral. However, when the features were connected by prior knowledge, it was much harder for subjects to learn the structure with the uneven distribution of crossover features. Experiments 2 and 3 found similar results with a slightly less uneven condition. We conclude that learning is a function of the interaction of category structure and prior knowledge rather than either one alone. Furthermore, knowledge benefits learning even when the category contains contradictions of the knowledge, so long as the contradictions are not very salient. 相似文献

Findings are reported concerning the hypothesized relationship between adoption of suicidal responses (ideation, threats, attempts) and antecedent negative self-attitudes. Data were provided by junior high school student (N = 3,148) responses to questionnaires administered three times at annual intervals. Antecedent negative self-attitudes were measured by a seven-item self-derogation scale at the first testing. Adoption of suicidal responses was indicated by earlier denial and subsequent affirmation of the response (self-reports). Findings indicate that suicidal behaviors are responses (whether or not subsequently continued) to experiences of negative self-attitudes in the more recent past. However, whether or not suicidal behaviors are related to self-derogating feelings in the more remote past can be seen as a function of a sex-social-class-mode of suicidal response interaction. 相似文献
