We investigated the role of inhibition failure in Obsessive Compulsive Disorder (OCD) through an eye tracking experiment. Twenty-five subjects with OCD were recruited, as well as 25 with Generalized Anxiety Disorder (GAD) and 25 healthy controls. A 3 (group: OCD group, GAD group and control group) × 2 (target eccentricity: far and near) × 2 (saccade task: prosaccade and antisaccade) mixed design was used, with all participants completing two sets of tasks involving both prosaccade (eye movement towards a target) and antisaccade (eye movement away from a target). The main outcome was the eye movement index, including the saccade latency (the time interval from the onset of the target screen to the first saccade) and the error rate of saccade direction. The antisaccade latency and antisaccade error rates for OCDs were much higher than those for GADs and healthy controls. OCDs had longer latency and error rates for antisaccades than for prosaccades, and for far-eccentricity rather than near-eccentricity stimuli. These results suggest that OCDs experience difficulty with behavior inhibition, and that they have higher visual sensitivity to peripheral stimuli. In particular, they show greatest difficulty in inhibiting behavior directed towards peripheral stimuli. 相似文献

认知诊断模型选择是认知诊断评估中重要研究问题之一。在实际应用中实践者并不知道真正拟合数据的模型,通常会用模型拟合指标检验模型与数据的拟合程度。从测量结果质量来看,除保证模型与数据拟合之外,还需要重点评价模型诊断结果的信度和效度等。考虑到以往研究大都采用基于信息量的拟合指标去判定模型与数据的匹配性,本研究提出综合考虑模型拟合指标与信度指标用于模型选择或评价模型误设。考虑实验因素为真实模型或分析模型(DINA模型、G-DINA模型、R-RUM模型)、样本量、题量和属性个数,在五因素(3×3×2×2×2)实验设计条件下,比较Bootstrap区间估计的属性分类一致性信度平均数与标准误和常用的拟合统计量-2LL、AIC、BIC对正确模型的选择率。结果表明:-2LL在题目数量多的情况下表现较好,而AIC、BIC在被试量较大的情况下表现较好,在不同的研究条件下,-2LL、AIC、BIC的模型选择率很不稳定,而用Bootstrap法估计的属性分类一致性信度平均数和标准误在不同研究条件的模型选择率较稳定,总体表现较好。 相似文献

由于齐国和鲁国的治国策略不同,反映到他们的教育思想上也存在着差异。齐国开展教育的目的很明确,那就是富民强国,称霸诸侯,而鲁国则是为了维护和推行西周宗法社会的礼制。本文借助现有齐、鲁文化典籍就齐、鲁教育思想的相同点与差异处进行了初步探析。 相似文献

塞尔的"行为式如何进行"一文发表在1989年的<语言学与哲学>(Linguistics and Philosophy)期刊上;三年后,同样从事言语行为理论研究的学者巴赫(Bach)和汉利什(Harnish)在同一个期刊上联名发表"行为式如何真正进行:给塞尔的回复(How Performatives Really work:A Reply to Searle)".塞尔在文章中曾抨击其他学者对行为式话语的研究,巴赫、汉利什就是遭他点名批评的当事人. 相似文献

To assess the relationship of family functioning to problem behaviors and alcohol and drug use among youth, researchers must test the effects of interventions using suitably constructed and psychometrically sound scales. This study evaluated whether originally calculated coefficients alpha underestimate the reliability of the family functioning measures given. Through exploratory factor analysis, estimates of alternative internal consistency reliability which might improve the estimate of reliability were examined. Responses of 755 adults from Strengthening Multi-ethnic Families and Communities were analyzed. Coefficients alpha for two scales were modest (alpha = .68 and alpha = .75), and factor analysis indicated that the scales were multidimensional. After exploratory factor analysis, the reassessment of reliability based on the extracted factors indicated an overall increase in the coefficients alpha. 相似文献

The present study examined the factorial structure of a Chinese language version of the self-report Dimensional Assessment of Personality Pathology Questionnaire in 581 adults. Four factors were extracted (Emotional Dysregulation, Dissocial, Inhibition, and Compulsivity) that are similar to the factors extracted in the scales' normative clinical and general population samples from North America (factor comparability coefficients range from .88 to .96), supporting the idea that this trait structure is invariant across diverse populations. The internal consistency of the scales (Cronbach's alpha) was satisfactory across age and gender groups with the exception of the Intimacy Problems scale. Possible explanations for the poor internal consistency of the Intimacy Problems scale, such as cultural differences in social factors influencing marital and romantic relationships in Chinese populations, as opposed to other populations are discussed. 相似文献

Eleven-month-old European-American, Japanese, and Chinese infants (ns = 23, 21, and 15, respectively) were videotaped during baseline and stimulus episodes of a covert toy-switch procedure. Infants looked longer at the object during the expectancy-violating event (stimulus episode) but did not produce more surprise-related facial expressions. American and Japanese infants produced more bodily stilling during stimulus than baseline, and American infants also produced more facial sobering. Naive raters viewing both episodes could correctly identify the expectancy-violating event. Rater judgments of surprise were significantly related to infants' bodily stilling and facial sobering. Judgments of interest were related to cessation of fussing. Thus, observer judgments of infant emotions can be systematically related to behaviors other than prototypic emotional facial expressions. 相似文献
