We investigated exploratory eye movements to thematic pictures in schizophrenic, attention-deficit/hyperactivity disorder (ADHD), and normal children. For each picture, children were asked three questions varying in amount of structure. We tested if schizophrenic children would stare or scan extensively and if their scan patterns were differentially affected by the question. Time spent viewing relevant and irrelevant regions, fixation duration (an estimate of processing rate), and distance between fixations (an estimate of breadth of attention) were measured. ADHD children showed a trend toward shorter fixations than normals on the question requiring the most detailed analysis. Schizophrenic children looked at fewer relevant, but not more irrelevant, regions than normals. They showed a tendency to stare more when asked to decide what was happening but not when asked to attend to specific regions. Thus, lower levels of visual attention (e.g., basic control of eye movements) were intact in schizophrenic children. In contrast, they had difficulty with top-down control of selective attention in the service of self-guided behavior. 相似文献

Whenr Principal Components are available fork variables, the correlation matrix is approximated in the least squares sense by the loading matrix times its transpose. The approximation is generally not perfect unlessr =k. In the present paper it is shown that, whenr is at or above the Ledermann bound,r principal components are enough to perfectly reconstruct the correlation matrix, albeit in a way more involved than taking the loading matrix times its transpose. In certain cases just below the Ledermann bound, recovery of the correlation matrix is still possible when the set of all eigenvalues of the correlation matrix is available as additional information. 相似文献

Positive affect has been neglected in evaluation of group treatment efficacy. This pilot study for individuals with heart failure illustrates the contribution of positive affect to change processes. Assessment of positive affect pre- and post-group intervention can yield a better understanding of individuals' adjustment to heart failure, and provide additional information for selection of specific treatments for each individual. In an era characterized by standardized measures of outcome, inclusion of positive affect provides additional opportunity to document contributions in improving health related quality of life (psychosocial and physical functioning) of clients with heart failure. 相似文献

Two studies are reported addressing the reliability of the Behavioral and Emotional Rating Scale (BERS). The first study investigated test-retest reliability over a two-week period to determine the stability of the measure over time. The second study investigated inter-rater reliability between two teachers or classroom aides who were familiar with a student to determine the consistency with which the measure can be used by different individuals. In each study, samples were drawn from populations of students identified with emotional or behavioral disorders as specified by federal statutes. Reliability coefficients in each study were above .80, the standard recommended for screening tests that are reported individually, and in most cases above .90. Implications for use of the BERS are discussed. 相似文献

The problem of decision-making capacity in patients with dementia, such as those with early stage Alzheimer's, can be vexing, especially when these patients refuse life-sustaining medical treatments. However, these patients should not be presumed to lack decision-making capacity. Instead, an analysis of the patient's decision-making capacity should be made. Patients who have some degree of decision-making capacity may be able to make a choice about life-sustaining medical treatment and may, in many cases, choose to forgo treatment. 相似文献

Children showing a comorbid behavior pattern of hyperactivity-impulsivity-inattention and conduct problems (HIA + CP) were contrasted to children having only an internalizing and externalizing behavior pattern (I + E) and matched controls. Children displaying the HIA + CP behavior pattern were at greater risk on a number of outcome measures in social and academic domains beginning in Grade 3 and continuing into Grade 4. The most marked differences among the three groups were found on peer measures of rejection and friendship and teacher ratings of social skills. On average, almost two-thirds of the HIA + CP group were rejected by their peers compared to one-third of the I + E group and only 12.5% controls. Over 70% of the HIA + CP group had no reciprocated friendships from Grade 3 to Grade 4 compared to less than half of the I + E group and approximately one-fourth of controls. Contrary to much theorizing in the literature, the HIA + CP and I + E groups showed average levels of academic self-concept and did not differ from controls in on measures of social self-concept and academic self-concept and general self-esteem. These findings were interpreted in light of positive illusory biases and the established link between aggressive behavior and egotism. The current article offers partial support for Lynam's (1996) notion of the fledgling psychopath. 相似文献

This article reports on the integrated application of cognitive therapy, transactional analysis techniques, and the behavioral technique of response prevention using self-instructional training and behavioral substitution in a brief therapy approach. These methods were applied in the case of a young man who presented with compulsions to perform repetitive and ordering rituals with the belief that it would prevent his girlfriend from becoming pregnant. A 21-year-old white male who had performed 3 to 5 hours of rituals daily for several years was able to eliminate the majority of his compulsive behaviors and reduce his level of anxiety after eight clinical therapy sessions. Results were maintained at 6-month follow-up. The clear precipitating factors and the unusual maintaining variables for the disorder in the client are described. The author discusses the case in light of current theoretical, therapeutic, and biomedical understandings of the disorder. 相似文献
