The genesis of reading ability: What helps children learn letter-sound correspondences?

Knowledge of letter-sound correspondences underpins successful reading acquisition, and yet little is known about how young children acquire this knowledge and what prior information they bring to the learning process. In this study, we used an experimental training design to examine whether either prior letter awareness or prior phonemic awareness directly assists preliterate children in subsequently learning letter-sound correspondences. Here 76 preschoolers received 6 weeks of training in either letter awareness, phonemic awareness, or control tasks and then received a further 6 weeks of training in either letter-sound correspondences or control tasks. There was limited evidence that prior training in either phoneme or letter awareness directly assisted learning of letter-sound correspondences, although phonemically trained children appeared to show some advantage on recognition tasks. Overall, the data suggest that there is little value in training preschoolers in either letter forms or sounds in isolation in advance of providing instruction on the links between the two.     

Marginally perceptible outcome feedback, motor learning and implicit processes

Participants struck 500 golf balls to a concealed target. Outcome feedback was presented at the subjective or objective threshold of awareness of each participant or at a supraliminal threshold. Participants who received fully perceptible (supraliminal) feedback learned to strike the ball onto the target, as did participants who received feedback that was only marginally perceptible (subjective threshold). Participants who received feedback that was not perceptible (objective threshold) showed no learning. Upon transfer to a condition in which the target was unconcealed, performance increased in both the subjective and the objective threshold condition, but decreased in the supraliminal condition. In all three conditions, participants reported minimal declarative knowledge of their movements, suggesting that deliberate hypothesis testing about how best to move in order to perform the motor task successfully was disrupted by the impoverished disposition of the visual outcome feedback. It was concluded that sub-optimally perceptible visual feedback evokes implicit processes.     

运动员退役过程的心理定性分析：成功与失败的个案研究

研究采用定性分析的方法,旨在探索我国运动员退役过程中为什么有的运动员能够顺利退役,重新开创新事业,而有的运动员却不能。研究以Torregrosa等的理论模式为设计思路,采用综合个案研究设计,选取4个成功和4个失败个案,通过访谈、文献和语言分析技术,对8个运动员退役过程中的意识和行为进行剖析。结果发现运动员在退役过程中,主要在心理状态、退役意识、退役计划、自我调节、社会支持和生活满意度6个方面,反映出成功退役的运动员与失败退役的运动员之间的不同特征。成功退役的运动员通常有一个良好的退役意识。主动计划选择退役后的事业发展;退役失败的运动员则表现为对退役问题消极回避的应对行为。文章就这些发现进行了讨论,并建议了进一步定量研究的方向     

年老化与文本理解

年老化与文本理解的研究表明,老年人在表层形式和文本基础两个低水平表征上的理解和记忆能力下降,而在情境模型的建构和提取、更新等加工过程中都没有发现由于年老化引起的能力下降。在介绍这些研究的基础上,从情境模型与另两个低水平加工的不同特点和老年人自身的特殊性两个方面分析了老年人在不同层次表征水平加工能力差异的原因。对情境模型水平加工能力保持的潜在机制及相关的影响因素,以及如何弥补在低水平加工中认知能力因年龄而产生的下降等问题还需要进行探讨     

中小学生的情绪表达方式认知及其与同伴接纳的关系

本研究采用D.Matsumoto等编制的情绪表达规则评估问卷,探讨了237名中小学生情绪表达方式的认知发展,并通过同伴提名法选择了192名同伴关系良好和同伴关系不良的中学生为被试,探讨了情绪表达方式认知与同伴接纳的关系。结果表明:情绪类型与情境类型对中小学生多种情绪表达方式的认知具有主效应;中小学生的情绪表达向更具有社会效益方向发展,对自我和他人情绪表达存在认识分化,并随年龄而增加;同伴关系不良的中学生在情绪表达的认知上存在发展滞后。     

视觉意识及其神经机制

视觉意识的神经机制是当前认知神经科学研究的热点问题之一。过去普遍认为视觉信息加工主要有两条通路:腹侧通路和背侧通路;而新近的研究表明还存在不经过初级视觉皮层(V1区)的第三条通路。高级视觉皮层、V1区和皮层下结构都对意识觉知的产生起到了相应的作用。已有的实验证据表明,意识的产生过程异常复杂,仍有很多问题值得继续深入讨论和研究。

人的存在的历史性及其现代境遇

This article argues that the problem of modernity concerns the circumstances of existence and human destiny in modern times. To understand the nature of this problem and find the corresponding solution, we need to reinterpret the thought of Karl Marx regarding the contradictions of human existence and its historical dimensions. Following Marx’s line of thinking, this article reviews his critical sequence, creative transformation, and development of duality of thought on man and the world in Western history, focusing on the following four issues: (1) how Marx, on the basis of man’s sensuous objective activities, observes the duality of man and the world as well as the relationship between man’s internal and external activities; (2) how Marx discloses the true connotation and real significance of man’s historical existence, history, and historicity; (3) how Marx reveals the inherent contradictions of modern capitalist society and the destiny of modern man based on historic thought concerning man’s existence; and (4) by praising Marx’s views on material production and the eternal significance of ancient Greek culture, the article reveals another dimension of Marx’s thought, a dimension that tends to be ignored. This article holds that in this era of globalization, it is extremely important and urgent to have an in-depth understanding of Marx’s historical thoughts regarding human existence and of the feasibility of his theory. Moreover, it is imperative to further develop this understanding to create a clearer picture of our own path of development and our outlook on humanity.

拥有关系信息情境模型建构的影响因素

该研究修正了Radvansky1997年的实验设计 ,运用扇效应技术系统地探讨影响建构拥有关系情境模型的因素。共包括 4个实验 ,被试为 180名一年级本科生 ,研究材料是“1人 /多物”与“多人 / 1物”两类表示拥有关系的句型 ,每类句型都有 3种扇水平 ,用计算机逐个呈现句子 ,要求被试迅速再认作出按键反应 ,用MANOVA分析了被试对不同扇水平的两类句型的反应时。实验 1在中文条件下重复了Radvansky1997年的实验 ;实验 2探讨在明确的相同空间条件下 ,对“多人买 1物”拥有行为句式的整合是否表现出扇效应 ;实验 3探讨在信息采用顺向展开的情况下 ,“多人买 1物”拥有行为句式的整合是否表现出扇效应 ;实验 4进一步探讨在具有相同时空状语的条件下 ,“1人有多物”与“多人有 1物”两类拥有状态句式的整合是否表现出扇效应。结果表明 ,当具有明确的时空信息情况下 ,或者当信息顺向展开的情况下 ,“多人买 1物”的拥有行为句式的整合均没有表现出扇效应 ;而在有相同时空状语情况下 ,“1人有多物”的拥有状态句式的整合也没有表现出扇效应 ;说明这些句式可以整合为同一情境模型 ,与Radvansky的研究结果不同。研究结果初步表明 ,享有共同概念的若干事件信息是否整合为同一个情境模型 ,受到动词的动作性程度、是否有相
