语素意识在儿童汉语阅读中的作用 总被引:16,自引:0,他引:16
文章考察了语音意识、语素意识和命名速度在儿童汉语阅读中的作用。结果发现:语素意识和命名速度对汉字命名组词具有显著的预测作用;而语素意识和语音意识对同音字识别具有显著的预测作用。语素意识是唯一显著预测两种不同阅读任务的认知变量。对阅读障碍儿童所存在的缺陷进行分析,结果发现:76%的阅读障碍存在语素缺陷;相比之下,分别有43%和41%的阅读障碍存在语音缺陷和命名速度缺陷。结果表明汉语的语素意识在儿童阅读中具有重要作用,语素缺陷有可能成为儿童汉语阅读困难的主要原因。 相似文献

动态视觉加工与儿童汉字阅读 总被引:14,自引:0,他引:14
使用视觉阈限测验、图片命名、字形相似性判断实验和语音意识等测验 ,考察了小学五年级儿童视觉加工技能与汉字阅读之间的关系。结果发现 :动态视觉加工与图片命名错误率、字形判断反应时和错误率、语音意识均有显著相关 ,静态视觉加工只与图片命名错误率相关显著 ;控制识字量后的偏相关分析显示 ,动态视觉加工与其他变量的相关关系不变 ,静态视觉加工与图片命名错误率的相关不再显著 ;回归分析发现动态视觉加工在识字量和语音意识的影响控制后 ,能够分别解释阅读流畅性、字形判断反应时和图片命名错误率 7%、2 5 %和 5 6 %的变化 ;语音意识能够解释识字量和阅读流畅性 9%和 10 %的变化 ;对差读者的动态视觉加工和语音意识分析发现 ,儿童在这两种测验上的个体差异很大。上述结果表明 ,阅读过程受基本知觉技能影响 ,动态视觉加工作用于汉字阅读的特定过程。 相似文献

Baddeley和Hitch(1974)提出的工作记忆模型被广泛地应用数学运算领域,但是已有研究还缺乏系统性。首先,当前的研究主要集中在加法和乘法两种运算上,较少涉及减法、除法和更为抽象的代数运算;第二,研究者对语音环路和中央执行系统的作用进行了较深入的研究,但常常忽略视空间模板的作用;第三,工作记忆在数学运算过程中的作用具有动态性,它受到一些外部因素、数学任务内在因素和个体认知因素(如认知策略)的影响;第四,几乎有关研究都肯定中央执行系统在数学运算过程中的重要作用,然而负荷于中央执行系统的次级任务所含成分或功能的复杂性,导致我们很难确定中央执行系统如何作用于数学运算。对这些问题的研究将是未来可能的研究方向 相似文献

神经科学家F.Pulvermüller根据Hebb的“细胞群集”学说和相关性学习原理构建的“语言表征的神经生物学理论”首次试图基于皮层功能网络来解释语音、词汇和句法在大脑皮层的表征机制,不仅能较好地描述语言活动中经典语言脑区与其它参与活动脑区的相互关系,也对语言加工的大脑功能偏侧化与整合现象作了合适的说明。本文介绍了这一理论的主要观点和研究资料,并提出了一些尚需进一步研究的问题。 相似文献

第二语言学习过程是社会互动情景中的言语活动,"热"的社会化过程是第二语言学习过程的有机组成部分;形成第二语言情景下的文化心理参照系认知能力和文化适应能力是第二语言的言语能力重要内容;第二语言学习过程中的言语变异现象部分源于学习者的社会心理结构特征。 相似文献

This study reports on the psychometric properties of the Femininity Ideology Scale (FIS) from the responses of 407 undergraduate
participants in the USA. Factor analysis supported the five factor structure. Cronbach alpha coefficients of the factors and
total scale were adequate. Support for discriminant validity was found after examining the relationship between the FIS and
the Bem Sex Role Inventory, which measures feminine traits. Support for convergent validity was found after examining, first,
with the entire sample, the relationships between the FIS and the Male Role Norm Inventory, and second, with the female sample,
the relationships between the FIS and the Feminist Identity Development Scale. We also found that FIS scores vary in relationship
to the social contextual variables of race/ethnicity and sex. 相似文献

Being paired with an attractive partner increases perceptual judgements of attractiveness in humans. We tested experimentally for prestige bias, whereby individuals follow the choices of prestigious others. Women rated the attractiveness of photographs of target males which were paired with either popular or less popular model female partners. We found that pairing a photo of a man with a woman presented as his partner positively influenced the attractiveness of the man when the woman was presented as more popular (Experiment 1). Further, this effect was stronger in younger participants compared to older participants (Experiment 1). Reversing the target and model such that women were asked to rate women paired with popular and less popular men revealed no effect of model popularity and this effect was unrelated to participant age (Experiment 2). An additional experiment confirmed that participant age and not stimulus age primarily influenced the tendency to follow others' preferences in Experiment 1 (Experiment 3). We also confirmed that our manipulations of popularity lead to variation in rated prestige (Experiment 4). These results suggest a sophisticated model‐based bias in social learning whereby individuals are most influenced by the choices of those who have high popularity/prestige. Furthermore, older individuals moderate their use of such social information and so this form of social learning appears strongest in younger women. 相似文献

At the heart of debates over underlying causes of autism is the “Kanner hypothesis” that autistic deficits in social reciprocity, and a cognitive/perceptual ‘style’ favouring detail-oriented cognition, co-vary in autistic individuals. A separate line of work indicates these two domains are normally distributed throughout the population, with autism representing an extremity. This realisation brings the Kanner debate into the realm of normative co-variation, providing more ways to test the hypothesis, and insights into typical development; for instance, in the context of normative functioning, the Kanner hypothesis implies social costs to spatial/numerical prowess. In light of this growing body of research, we review relevant factor analytic and correlational, behavioural studies. Findings are then synthesised into three themes: an alternative triad of primary autistic trait categories – Social Interaction Deficits, Cognitive Inflexibility, and Sensory Abnormalities – that more accurately reflects the factor structure of autistic traits; continuity between clinical and non-clinical autism-spectrum trait presentation; and indications that although social and non-social autistic traits may be initially independent, Kanner-like co-variance emerges behaviourally from dynamic trait interactions over the course of development. A dynamic developmental model subsuming these patterns is offered, and its advantages demonstrated in a novel account of ritualistic behaviours: as developmentally emergent, compensatory mechanisms for interactions between cognitive inflexibility and sensory abnormalities. We conclude with the broader imperative that behavioural scientists appealing for directly and exclusively genetic links may instead benefit from a developmental framing within their own discipline. 相似文献
