About 30–40% of stroke patients suffer from visual field defects following injury. These can interfere with the standard neuropsychological assessment and complicate the interpretation of tests that use visual materials. However, information about the integrity of a patient's central visual field is often unavailable. We, therefore, designed a screening tool, the computerized visual field test (c‐VFT), specifically targeted at providing easily available, but rough, information about patients' central visual field. c‐VFT was tested in two samples of stroke patients. Eleven patients were tested on c‐VFT and on the Esterman test. Five patients were tested on c‐VFT and the Humphrey Visual Field Analyzer (HFA), central 10‐2. Criterion validity of the c‐VFT was investigated by calculating quadrantwise intraclass correlation for both comparisons. For the HFA comparison, we also calculated point‐to‐point intraclass correlation, sensitivity, and specificity. Analyses revealed moderately good correspondence between c‐VFT and the Esterman test, and between c‐VFT and HFA 10‐2, respectively. When looking specifically at test points within one degree of visual angle apart in the two tests, intraclass correlation increased. For these points, the sensitivity of c‐VFT was 0.89 and specificity was 0.97. While the c‐VFT is not designed to be diagnostic nor to replace the detailed visual field analysis, this study shows that it provides a reasonable screening of the central visual field. The test can easily be used and will be made freely available to neuropsychological clinicians and researchers.  相似文献

This study explored the impact of psychological outcomes to war on response to subsequent natural disaster. Participants were 312 military personnel, 66% of whom saw Gulf War duty. All were exposed to the 1992 Hurricane Andrew. Troops were compared on reported traumatic events, hurricane impact responses, and psychological symptoms in subgroups defined by war or no war exposure prior to hurricane and by presence or absence of war-related posttraumatic stress disorder (PTSD). Data were gathered in face-to-face clinical assessments. War trauma prior to hurricane was associated with more reported traumatic events, greater fears for safety during the hurricane, and heightened psychological symptoms. Troops with preexisting war-related PTSD showed more adverse psychological hurricane sequelae and reported more traumatic events, higher depression, anxiety, anger, PTSD symptoms, and physical symptoms, and lower self-esteem than those free of diagnoses. Results point to the negative influence of exposure to one traumatic event on the experience of and response to a subsequent stressor.  相似文献

This study examined the psychometric properties of the Sutter-Eyberg Student Behavior Inventory (SESBI) in a rural sample of children and adolescents. Thirty-eight 5th- through 12th-grade teachers completed the SESBI on 726 children in their classrooms. High Cronbach's alphas supported the reliability of the SESBI scales in this population. Higher SESBI scores were obtained by boys than girls and by African American students than Caucasian students, more so at lower grades. Teacher's race did not affect SESBI scores. In contrast to children with developmental delay, children with learning disabilities obtained higher scores than others on the SESBI Intensity scale but not on the Problem scale. This suggests that teachers of children with learning disabilities recognize the higher frequency of problem behaviors in their students but do not consider these behaviors to be problems for themselves. On both SESBI scales, children with developmental delay were not distinguishable from peers without developmental delays.  相似文献

Conclusion The Group Ministry approach is an attempt at one way of facing the need for renewal of the Church in its understanding of the means of Christian commitment and witness in the world. There are many dangers in a Group Ministry. It runs the risk of becoming apower block or separation of men and women from their primary responsibility in the local church; of facingemotional strain on those who must work closely together in a group of sinners; of developing apsychic dependence on each other rather than looking to Christ as the primary source of support and unity; of becomingless efficient when more workers are placed in one small area; oflacking a sense of direction because one leader is not given responsibility and authority.Yet the Group Ministry approach takes these risks in the knowledge that the Church must work to fashion patterns by which it may again express itself with power in places where the word is scarce.For further information about the East Harlem Protestant Parish, readers may write directly to 2050 Second Avenue, New York 29, N.

The present study used a lexical decision paradigm to study the summation of priming effects in normal and aphasic participants. The amount of priming produced by pairs of definitionally converging associative words was compared to the amount of priming produced by pairs of single associative words and non-words in two experiments in which the ISI between primes and targets varied from 200 ms (Experiment 1) to 600 ms (Experiment 2). Control subjects showed a pattern of additive summation priming at the short ISI and overadditive summation priming at the longer ISI. Broca's aphasics showed overadditive priming at the short ISI and no significant priming at the longer ISI; Wernicke's aphasics showed no significant priming at the short ISI and additive priming at the longer ISI. These results suggest that aphasics differ from normals in their ability to integrate the activation derived from multiple linguistic associations and may provide an account of some of the clinical phenomenology of these patients.  相似文献

This investigation examined gender differences in communication with parents, peer group selection, and academic motivation as related to drug use among adolescents (290 girls, 237 boys; age range = 12-19 years). For girls, increased self-expression with parents was associated with greater academic motivation, more academically motivated friends, fewer drug-using friends, and less overall drug use. For boys, self-expression was positively related to academic motivation. For both boys and girls, having drug-using friends predicted increased drug use, while having academically motivated friends predicted decreased drug use. For girls only, age and academic motivation predicted drug use as well. These findings indicate that peer group selection and academic motivation may mediate the relationship between drug use and parent-adolescent communication for girls only.  相似文献

Data gathered from 1,430 teenage student drivers and 880 teenage traffic violators were used to examine the levels of exposure to risky driving behaviors and perceptions concerning the level of danger of such behaviors. For student drivers, 55% reported exposure to risky driving by being in a car with a driver engaging in such activities as drunk driving, drag racing, and reckless driving. For the traffic violators, 43% had been engaged in one or more of the risky driving behaviors. Teenagers who had been exposed to risky driving practices were more accepting of risky driving behaviors.  相似文献

Low-income, rural adults and middle-income, urban adults provided oral definitions for eight common nouns. Two general issues were addressed: (1) whether the rural adults' definitions would conform to the well-documented Aristotelian form typically found among middle-class, well-educated adults; and (2) whether different definitional types would emerge for two different noun classes, social vs. object nouns. Participants' definitions were examined for conceptual content and linguistic form. Among rural participants, the mean proportion of definitions conforming to the Aristotelian model was .13, contrasted with .69 for the urban participants. Also, rural adults were significantly less likely to cast definitions in the conventional linguistic form than were urban adults. On other measures of definitional skill as well, rural participants demonstrated less mastery. There were no significant differences in definitional form between social and object nouns. Various explanations for the findings are considered.  相似文献
