汉字词笔划数对短时记忆容量的影响 总被引:1,自引:1,他引:1
短时记忆容量的测量有两种主要观点,即组块说和复诵回路说。本报告通过三项实验表明对汉字词短时记忆容量的测量应考虑字词的笔划复杂性。实验一使用频率相同的少笔划和多笔划汉字相比较,笔划少的字比笔划多的字记忆广度大;实验二用笔划数相近但音节长度不同的日本汉字相比较,发现音节长短对容量影响无显著差别;第三项实验是语音掩蔽对汉字词视听短时记忆的影响。结果表明视、听容量都下降,但视觉仍比听觉好。再一次指出汉字词短时记忆容量的测量应考虑其视觉特点。最后对汉字词笔划复杂性影响短时记忆容量的可能原因进行了讨论。 相似文献

清末民初发生在中国回族穆斯林和基督教传教士之间的"回耶对话",是历史上文明对话研究的生动个案。而促成两方积极对话的《回教考略》(《四教考略》有关伊斯兰教部分的单行本)一书,则是其中尤其值得关注的关节点。通过《回教考略》的出版以及版本状况的查询、《回教考略》对伊斯兰教批评的具体状况的分析、回族穆斯林学者针对《回教考略》有所反响的八个个案的收集(在回族穆斯林学者中有相当的代表性),我们可以认识到《回教考略》一书在引起回族穆斯林学者注意到并起而反驳基督教对伊斯兰教的批评等方面都有着重要的影响。而从文明对话的角度进行分析,我们还可以看到围绕着《回教考略》的回耶对话的一些特点:其一,这一回耶对话总体上是因为基督教对伊斯兰教的明确批评及试图传教引起的,回族穆斯林学者对基督教方面所描述的有关伊斯兰教内容的辩驳和对基督教的批评,具有必然性;其二,对于伊斯兰教方面而言,这一回耶对话有着相当的"卫教"色彩;其三,虽然当时基督教处于一种主动的且是强势的地位,但这一次回耶之间的对话,却大抵是在一种平等的关系下进行的。 相似文献

This study examined (1) the relative prevalence of childhood abuse and other pathological childhood experiences in China reported by outpatients with borderline personality disorder (BPD), with other personality disorders, and without personality disorders; and, (2) whether the primary predictors of BPD in North America are associated with the development of BPD in China. The childhood experiences of 203 outpatients with BPD, 109 outpatients with other personality disorders, and 70 outpatients without Axis II diagnoses were assessed with the Chinese version of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q). Patients with BPD reported significantly more physical, emotional, and sexual abuse than either comparison group. Four types of childhood experiences were significant predictors of BPD: maternal neglect, paternal antipathy, sexual abuse, and maternal physical abuse. The findings suggest that maternal physical abuse is as strong a predictor of BPD in China as sexual abuse, a finding not replicated in North America. 相似文献

Several studies have demonstrated age-related declines in general executive function and memory. In this study, we examined cross-sectional and longitudinal age effects in more specific cognitive processes that constitute executive function and memory. We postulated that, whereas some components of executive and memory functions would show age differences and longitudinal declines, other specific abilities would be maintained or even improve with repeated testing. In a sample of individuals ≥55 years old from the Baltimore Longitudinal Study of Aging, we found longitudinal declines in inhibition, manipulation, semantic retrieval, phonological retrieval, switching, and long-term memory over a maximum of 14 years follow-up. In contrast, abstraction, capacity, chunking, discrimination, and short-term memory were maintained or even improved longitudinally, probably due in part to repeated testing. Moreover, whereas several different abilities were correlated across participants' cross-sectional performance, longitudinal changes in performance showed more heterogeneous trajectories. Finally, compared with cross-sectional performance, longitudinal trajectories showed better distinction between participants with and those without later cognitive impairment. These results show that longitudinal cognitive aging of executive and memory functions is not a uniform process but a heterogeneous one and suggest that certain executive and memory functions remain stable despite age-related declines in other component processes.

Eight studies with data from 2316 students are presented describing the development and preliminary validation of the Physical
Appearance Perfectionism Scale (PAPS), a brief measure with two subscales: Worry About Imperfection and Hope For Perfection.
Results from exploratory and confirmatory factor analyses confirmed the measure’s two-dimensional structure. Moreover, correlation
analyses provided first evidence for the two subscales’ differential validity: Worry About Imperfection showed negative correlations
with positive self-perceptions of one’s appearance (e.g., appearance self-esteem) and positive correlations with maladaptive
concerns aspects of perfectionism, physical appearance concerns (e.g., body image disturbances), and body weight control whereas
Hope For Perfection showed positive correlations with positive striving aspects of perfectionism, positive self-perceptions,
and impression management. In addition, all PAPS scores showed high reliability (Cronbach’s alpha) and temporal stability
(test-retest). Overall the findings suggest that the PAPS is a reliable and valid instrument to assess positive and negative
aspects of physical appearance perfectionism. 相似文献

We used 18F-fluorodeoxyglucose small-animal positron-emission tomography to determine whether different styles of coping with stress are associated with different patterns of neuronal activity in the hypothalamus. Adult rats were subjected to immobilization (IMO)-stress or to a non-immobilized condition for 30 min, in random order on separate days, each of which was followed by brain-scanning. Some rats in the immobilized condition were allowed to actively cope with the stress by chewing a wooden stick during IMO, while the other immobilized rats were given nothing to chew on. Voxel-based statistical analysis of the brain imaging data shows that chewing counteracted the stress-induced increased glucose uptake in the hypothalamus to the level of the non-immobilized condition. Region-of-interest analysis of the glucose uptake values further showed that chewing significantly suppressed stress-induced increased glucose uptake in the paraventricular hypothalamic nucleus and the anterior hypothalamic area but not in the lateral hypothalamus. Together with the finding that the mean plasma corticosterone concentration at the termination of the IMO was also significantly suppressed when rats had an opportunity to chew a wooden stick, our results showed that active coping by chewing inhibited the activation of the hypothalamic-pituitary-adrenal axis to reduce the endocrine stress response. 相似文献

This article introduces a simple survey method to distinguish between two types of variables that affect happiness—type A, which exerts an absolute effect on happiness, and type B, which affects happiness only through social context. The authors validate the method by comparing its findings with the findings of a theoretically superior but less practical experimental method, and use the method to identify the AB nature of a variety of naturally-occurring variables among both college students and people with work experience. We conclude by discussing the limitation of this method as well as its potential to inform policymakers about where to invest resources in order to improve people’s happiness over time. 相似文献
