A variant of a line bisection test was devised. Patients with unilateral visual neglect and control subjects were asked to perform the test, which consisted of two subtasks: a verbal and a manual task. The verbal task was newly designed and did not require manual responses from the subjects. The manual task was similar to conventional line bisection tasks. This paper reports and discusses the results obtained from each task and their correlations. This technique is compatible with bedside examinations, does not require a complex apparatus, and provides useful data for the assessment of unilateral visual neglect. 相似文献

The question addressed here is whether misleading suggestions made to children a year after target events had occurred will alter long-term recall. One group (3-13 years old when injured and treated in a hospital Emergency Room) were given both misleading and accurate reinstating information a year later, and recall of target events assessed both 1 week and another year later (i.e., 2 years post-injury). A control group had recall assessed both 1 and 2 years post-injury. Misleading had little effect on children's recall 1 week later, although a few misled details were reported. However, a year later virtually none of the misleading information was incorporated into long-term recall. Rather, children were more, not less, accurate when recalling details about which they had been misled. Results were attributed to target events having been highly memorable and well rehearsed via previous recalls, and detection of discrepancies between memory and misleading information focusing attention on targeted details. 相似文献

通过对8名11~14岁初中生的深入访谈,初步探讨了处于初中阶段的青少年认同的亲社会行为。发现:(1)初中生最认同的亲社会行为是帮助行为,其次是交往行为。此外,安慰行为、公益行为、礼貌行为和遵规行为也被他们认同;(2)初中生对不同行为主体间发生的亲社会行为的认同有明显差异,他们更关心发生在他们之间的亲社会行为;(3)普通学校、打工子弟学校的初中生对帮助行为和交往行为认同的比率差异明显;(4)初中生认同的亲社会行为的种类不存在明显的性别差异。 相似文献

The authors examined the construct of psychopathy as applied to 130 adolescent offenders using 3 psychopathy measures and a broad range of DSM-TV Axis I diagnoses and psychosocial problems. Measures used in the study included the following: (a) Psychopathy Checklist-Youth Version, (b) Antisocial Process Screening Device, (c) a modified version of the Self-Report Psychopathy-II scale, and (d) the Adolescent Psychopathology Scale. Results from this study offer incremental support for the construct validity of psychopathy in youth. Psychopathy evidenced better convergent and discriminant validity results than did the disruptive behavior disorders (DBDs) such as oppositional-defiant disorder (ODD) and conduct disorder (CD). Despite this finding, psychopathy scales nonetheless correlated with other forms of psychopathology at a higher rate than was expected, suggesting that comorbidity is high even when psychopathy is used as a classification scheme. Also, hierarchical multiple regression was used to determine whether psychopathy offered an improvement in the prediction of previous violent and nonviolent offenses. The results for the current study were mixed, with only the PCL-YV significantly predicting previous violent and nonviolent offenses beyond the DBDs. The findings indicate that psychopathy may offer incremental improvement over DBDs with regard to level of comorbidity and perhaps even prediction. However, simply extending the adult construct of psychopathy to youth without considering the array of psychopathology that may accompany adolescent psychopathy could be misleading. 相似文献

The personality, psychopathological, and demographic differences between 330 alcoholic men referred for behavioral problems and 104 alcoholic men referred for medical problems were examined. The Minnesota Multiphasic Personality Inventory-2 indicated that those referred for behavioral problems showed more antisocial characteristics, while those referred for medical reasons had more subjective distress, were more highly introverted, and showed greater somatic preoccupation. Hispanic alcoholic men had a significantly higher proportion of medical referrals than Caucasian and African-American alcoholic men. 相似文献

Healthy control participants (46 women, M age=44.3 yr., SD=7.6; 29 men) were recruited to undergo a comprehensive neuropsychological battery and serve as a comparison group in a study of cognitive functioning in patients with Lyme isease. Participants were selected using Mitofsky-Waksberg random digit dialing. The Buschke 12-word, six-trial Selective Reminding Test was administered as part of the neuropsychological battery and normative data are presented stratified by age and sex. Performance on alternate forms of this measure were examined. Mean education, intelligence quotient, and Wide Range Achievement Test-3 Reading scores are reported. 相似文献

Variability in rhythmic movements has been interpreted as a signature of internal or peripheral noise processes. Grounded in an oscillator interpretation, this study hypothesized that period variability and drift arises from the asymmetry between target period and the limb's intrinsic dynamics. Participants synchronized to 7 target periods, swinging 1 of 3 pendulums in a continuation paradigm; 3 periods were longer, 3 shorter, and 1 identical to the preferred period. Results supported 5 predictions: Drift toward the preferred period was observed that scaled with the asymmetry. Variability was lowest for symmetry conditions and increased with the asymmetry. Variability decreased concomitant with the approach toward the preferred period. Periods exponentially approached the preferred period with positive autocorrelations up to 10 cycles. 相似文献

兴奋性氨基酸(EAAs) 广泛分布于中枢神经系统,参与多种生理过程包括学习、记忆和伤害感受等。然而,EAAs 受体的过度兴奋却可引发一系列细胞事件,最终导致神经元的损伤与死亡。许多神经退行性疾病如早老性痴呆、癫痫和肌侧索硬化症等都与EAAs 的兴奋毒作用有关。目前的研究表明,由EAAs 受体过度兴奋所引发的细胞内钙超载是导致神经元死亡的最终途径 相似文献

Two adolescents with learning disabilities were taught to use a self-management program to decrease off-task behavior in two general education classes and a study hall class. The self-management program included three components—a checklist, a behavior rating scale, and a self-monitoring form. A multiple baseline design was implemented across settings for each participant. The findings indicated that the self-management program was successful in all three settings in decreasing off-task behaviors. Additionally, the teacher ratings of student behavior were found to increase during self-monitoring, suggesting the overall behavior of the students improved during the self-management program. The results are discussed in terms of the novelty of using teacher ratings of student behavior to demonstrate a relationship between the implementation of the self-management program and teacher reports of changes in other classroom behaviors. 相似文献
