It has been suggested that neural systems for lexical processing of nouns and verbs are anatomically distinct. The aim of the present study was to investigate if brain asymmetry for the processing of these two grammatical classes is also different. Neurologically intact adults performed a lateralized lexical decision task with grammatically unambiguous words of high, medium, and low degrees of imagery. For error scores a right visual field (RVF) advantage and an overall effect of imageability were obtained. For latency scores grammatical class and imageability modified visual field differences: in the noun class a RVF advantage was obtained only for low imagery nouns, while for the verbs the RVF advantage was present for both medium and low imagery verbs. These results suggest that the participation of right hemisphere neural systems in the processing of verbs is more limited than in the processing of nouns.  相似文献

A Neuropsychological Approach to Intelligence   总被引:1,自引:0,他引:1  
This paper proposes that current psychometric intelligence tests are limited in evaluating cognitive activity. From a neuropsychological perspective, they fail to measure some fundamental cognitive abilities such as executive functions, memory, and visuospatial abilities. The analysis of the Wechsler Intelligence Scale presented shows that the original rationale for selecting the specific subtests included in the WAIS was unclear. The concept of a g factor in cognition is also analyzed, with the conclusion that the g factor continues to be controversial. The value of intelligence tests in predicting school performance is also criticized. It is proposed that the psychometric concept of general intelligence should be deleted from cognitive and neurological sciences. Finally, it is proposed that, in the future, neuropsychological instruments sensitive to more specific cognitive abilities replace current psychometric intelligence tests.  相似文献

本实验旨在探索儿童对抽象图画情绪寓意敏感性的发展规律以及文化因素的影响。被试年龄跨度从 5岁至高中学生。根据被试利用形态、主题、情绪等图片特性作为识辨依据的特点来发现规律。儿童对抽象图画寓意敏感性的发展与表征水平相关。年幼儿童只能利用颜色或图形等单一信息维量进行判断 ,年长儿童及中学生可以综合利用形态、主题、情绪等多个维量判断。在寓意明确的图片识辨中 ,儿童对积极寓意的识辨成绩较优。在双关寓意的图片识辨中 ,儿童组倾向于选择具有积极寓意的线索 ,而中学生组会受到识辨经验的影响。文化与教育方式影响儿童对抽象图画情绪寓意的理解。中国幼教方式有助于儿童对图画认知与情绪成分的识辨。  相似文献

Self esteem and body esteem were examined in a group of 35 relapsing-remitting multiple sclerosis (MS) patients using the Body Esteem Scale (BES) and the Eysenck Self Esteem Scale (ESES) and compared to age and sex matched normal controls. There were 23 females and 12 males in the MS patient's group; average age 38.9 years (range: 22-52). All participants completed the self-rated BES evaluating the following subscales: females - sexual attractiveness, physical condition and weight concern; males - physical attractiveness, physical condition and upper body strength. In addition all participants were scored, following a semi-structured interview, on the ESES. Psychiatric co-morbidity was excluded using a semi-structured interview by the consulting psychiatrist. All evaluations were carried out during the remitting phase. Statistical analysis, comparing patients to healthy controls, demonstrated lowered self-rating of the physical condition (males < 0.05, females < 0.001). On the other hand, no significant differences were found in the physical (male) or sexual (female)?attractiveness subscales. The mean ESES score in the patients group was 23.2 ± 4.0, slightly above the reported average. The controls mean ESES was 28.4 ± 3.6, (P < 0.05). No correlation was found between self and body esteem amongst M.S. patients. This study emphasizes impaired perception of body esteem in multiple sclerosis patients even in remission. The preservation of physical and sexual attractiveness may be related to the non-disfiguring nature of the disease. Preservation of self-esteem in MS patients suggests that body-esteem should be the focus of supportive treatment.  相似文献

20世纪欧洲大陆思想发展过程中一直有一种最为怪癖的现象,就是对自然科学缺乏研究。的确,科学文献似乎否认哲学有超乎生活经验的立足点,并力求以这种方式采取一种客观陈述的姿态。分析的科学哲学采取了这种表面上有价值的姿态,并且以文化和历史要素相结合为代价而得以发展。分析的科学哲学家们把他们的工作看作是使自然科学的方法形式化,他们的兴趣不是专注于文化的、历史的和个人的因素能够成为决定因素的发现过程以及其他领域。然而,科学的知识也像一切知识一样,涉及对某人揭示(诉说)某事。科学探讨意义,这些意义就是体现在语…  相似文献

一、有关技术的传统概念技术不过是人的劳作而已。它既是一种人为的事物也是一种人为的发明过程,其目的是由人制定的,从而也是由人所贯彻的。这就是从古至今技术的哲学人类学背景:从柏拉图的《普罗泰戈拉篇》到卡普(Kapp)和该伦(Gehlen)。他们都将技术说成是必然,因为人是一种有缺陷的生灵,而且他们对技术目的也都是在这样的标题下进行讨论,如加强、延伸以及替代我们可怜的人类器官或肢体,为的是生存竞争或改善我们的境况。但是,这种对技术的传统理解过于狭窄了,因为它没有涵盖这些东西,如教堂的建造、金字塔和庙宇,这些东…  相似文献

This is an effectiveness study of treatment outcome that relies on patients' perception of their mental health during and after psychoanalytic psychotherapy. Ninety-nine outpatients attending the IPTAR Clinical Center (ICC) responded to the Effectiveness Questionnaire (EQ) adapted from that developed by Consumer Reports. Effectiveness is studied from various perspectives. Findings indicated (1) an incremental gain in effectiveness scores from six to over twenty-four months of therapy; (2) an incremental gain with greater session frequency from one to two or three weekly sessions; (3) facilitation of effectiveness by the experience of a positive relationship with the therapist; (4) an interplay between clinical syndrome and treatment conditions. A method giving clinical validity to the quantitative findings is described. Brief summaries of two recorded interviews reveal differential reconstruction of events that had occurred during treatment. The findings are discussed from the vantage point of two hypotheses: cognitive dissonance and internalization of therapeutic experience.  相似文献

To investigate hemisphere function of experts, Go experts and novices were given two Salthouse-type visuospatial tasks. In Experiment 1, stimuli of 4 digits in 6 cells were projected to the left (LVF) or right visual field (RVF). There was no prominent group difference in identification of digits and locations. In Experiment 2, stimuli of 4 digits in 16 cells were projected to the LVF or RVF. Go experts showed more accurate performance than novices. Both groups showed the same laterality, an RVF advantage, in the number identification. However, in the location identification, Go experts showed no visual field difference, whereas novices showed an RVF advantage. Based on these findings, the relationship between task demand and hemisphere function of experts is discussed.  相似文献

A mirror effect was found for a stimulus manipulation introduced at test. When subjects studied a set of normal faces and then were tested with new and old faces that were normal or wearing sunglasses, the hit rate was higher and the false alarm rate was lower for normal faces. Hit rate differences were reflected in remember and sure recognition responses, whereas differences in false alarm rates were largely seen in know and unsure judgments. In contrast, when subjects studied faces wearing sunglasses, the hit rate was greater for test faces with sunglasses than for normal faces, but there was no difference in false alarm rates. These findings are problematic for single-factor theories of the mirror effect, but can be accommodated within a two-factor account.  相似文献
