孤独症和正常儿童心理理论能力比较   总被引:7,自引:3,他引:4  
目的考察孤独症儿童心理理论的特点,探讨孤独症心理理论缺失假说。方法18名3-15岁的孤独症儿童为实验组,30名3-16岁的正常儿童为对照组,接受了龚氏非文字智力测验以及“外表-真实任务”、“意外位置任务”和“意外内容任务”三个心理理论测验任务。结果⑴在龚氏非文字智力测验中,孤独症组IQ低于正常组(98.8±25.2/117.2±14.3,t=-2.760,P<0.05)。⑵所有被试在各项心理理论任务上的得分之间均存在显著正相关(r=0.612~1.000,P<0.01)。⑶孤独症组的外表-真实任务(247/927,u=-5.007,P<0.001)、位置错误信念问题(173/862,u=-5.661,P<0.001)、内容自我错误信念问题(178/725,u=-4.277,P<0.001)及内容他人错误信念问题(163.5/739.5,u=-4.639,P<0.001)得分均低于正常组。结论孤独症儿童心理理论发展水平远落后于同龄正常儿童,存在严重的心理理论缺损。  相似文献

This study compared the conditioning of averaged evoked potentials in 11 psychotic and 11 normal children (57 experiments). Evoked potentials, like the blocking of alpha rhythm, can be conditioned by coupling a short sound of low intensity with an intense light flash. In normal children, the amplitude of the potential evoked by sound at the occipital region is small and quite variable. Its amplitude increases and its variability diminishes after coupling of sound and light. Also its form may resemble the potential evoked by light, especially in its rhythmic after-effects. In psychotic children auditory evoked responses are variable and small and remain so during the coupling of sound and light. Instead, these patients respond to the sound with a late slow wave, which is strong and generalized. It is particularly prominent during conditioning and resembles the slow waves which follow the visual evoked potentials in these autistic children. This slow wave can be experimentally reproduced in normal Ss by Psilocybine. It also resembles in certain ways the slow waves provoked by movement or its anticipation in normal Ss but it appears here during sensorial conditioning which requires no movement. We suspect that this slow wave may reflect a diffuse motor component in the perceptual and associative processes of these autistic children.  相似文献

This study tested the hypothesis that language processing by high-functioning, verbal autistic children is less influenced by global semantic context than that of their normal peers. Behavioral measures of reaction time and error rate were employed to evaluate speed and accuracy in classifying auditorally presented words according to a superordinate category label. In addition, an electrophysiologic index of semantic expectancy, the N4 component of auditory event-related potentials, was used to assess the relative levels of activation of in-category versus out-of-category words. Age and nonverbal IQ matched groups of 8 normal and 8 nonretarded autistic children were studied. The age range for the autistic participants was 7 years 4 months to 10 years 8 months (M = 8 years 10 months) and for the normal participants was 7 years 6 months to 10 years 11 months (M = 9 years 1 month). Participants responded with a finger lift to any word belonging to the animal category. The instruction set and stimulus list composition (i.e., 50% animal words and 50% unrelated nonanimal words) set up an expectancy for animal words. The autistic children were slower in classifying targets as animal words and made more errors than the normal children, but the increase in error rate was not statistically significant. As expected, N4 was larger for the nontargets than for the targets in the normal control group. By contrast, the autistic children showed no difference in N4 amplitude for targets versus nontargets, providing support for the hypothesized failure of the categorical context to set up a selective expectancy for the target words. As in prior studies, the P3 component to the target stimuli was significantly reduced in amplitude in the autistic group. An unexpected finding was an increased latency of the N1 and P2 components of the obligatory auditory evoked potential that was most prominent over the left temporal region.  相似文献

儿童孤独症是一组广泛性发育障碍,症状一般在1或2周岁时显现.其症状主要表现在语言发展障碍、社会交往障碍、认知障碍、感知觉障碍方面[1].虽然孤独症患儿在认知、社会情感和人际交往方面的发展有很大障碍,但他们在某些方一面,如记忆力、运动能力、音乐能力或空间概念上都显示出非凡的能力[2].大量的研究已经表明,孤独症儿童对音乐有不同寻常的兴趣,并显示出不同寻常的感受力和注意力,其中有些甚至是音乐天才,而音乐用于孤独症的治疗已经取得了显著的效果.舍温(Sherwin)在1953年就已经发现了孤独症儿童对音乐有明显的反应.比如在音调的记忆,古典音乐片断的认知,演奏乐器、歌唱、聆听音乐上都显示出强烈的兴趣与能力[3].  相似文献

醉酒者脑电和正常脑电非线性特性的比较评估   总被引:1,自引:0,他引:1  
为了刻画醉酒者脑电和正常人脑电之间的多种非线性特征并区分两者之间的差异。采用基于信息理论的排列熵(PE)、奇异值分解(SVD)熵、近似熵(ApEn)和基于混沌理论的相关维(CD)、最大Lyapunov指数(LLE)、Hurst指数,分别对35个醉酒者和35个正常人的脑电时间序列进行计算分析。同时,对选用的6种非线性特征分析方法在这两组数据的分析结果上,运用方差分析(ANOVA)进行统计学的比较评估分析。结果表明,ApEn、CD和LLE这三种方法能够显著区分这两组数据,但由于算法时间复杂度较高,不宜用于实时分析;而PE和Hurst指数方法相对简单、算法复杂度较低、分析结果有效,可以应用于对正确性和实时性要求均较高的EEG数据分析处理中。  相似文献

General developmental patterns of mean electroencephalogram (EEG) coherence, computed from 16 scalp locations, were separately determined for 224 girls and 284 boys ranging in age from 2 months to 161/2 years. Principal components analysis of mean coherence developmental trajectories demonstrated gender-specific patterns and timing differences in the onset of synchronized-asynchronized oscillations. No brain region in either sex had a maturational plateau period. Differences in gender-specific rhythms were statistically significant in brain regions paired with frontal and temporal cortices. From birth to age 6 years, girls exhibited synchronized EEG coherence peaks in cortical regions known to be associated primarily with concurrent discrimination, language processing, fine motor skills, and social cognition. During this same early period, boys exhibited synchronized EEG coherence peaks in cortical regions known to be associated primarily with spatial-visual discrimination and executive planning related to gross motor movement, visual targeting, and accessing stored information. After age 6 years, both sexes exhibited large shifts in EEG coherence patterns with female synchronized changes now occurring in occipital and right temporal processing regions and male synchronized changes now occurring in frontal and left temporal processing regions.  相似文献

The delayed and disordered language of autistic children isdiscussed as it affects the delivery of health care and otherservices in interdisciplinary settings. Current research isreviewed in terms of four major areas of communication-relateddeficits associated with early childhood autism: language delay,need for sameness, and impairments in social and informationprocessing skills. Within this framework, methods for communicatingwith autistic children in health-care settings are presented.  相似文献
