句子阅读理解过程中句意的建构时间

一般语言学理论认为, 在句子阅读理解过程中, 句子意义建构是基于词汇语义整合的, 其反映在N400之上, 开始于词语呈现后约250 ms。然而, 近年关于语义P600效应的研究却提示句意建构可能存在多通道或方式, 读者甚至可能在N400反映的加工出现之前就已建立了初步句意。为探明在句子阅读理解过程中是否存在比N400反映的加工更早的句意建构, 以及如果存在这样的句意建构, 其是从何时开始的, 本研究开展了四个实验。实验1发现被试在句末双字词呈现200 ms后已将其联系到上文语义表征而建立了句意, 提示句意建构开始于N400反映的加工出现之前。实验2与3进一步发现, 读者开始建立句意的时间约在句末词呈现了150 ms之时。实验4排除了实验1~3效应的其他一些可能解释, 提升了实验1~3结果的可靠性。总体上, 本研究提示：在句子阅读理解过程中, 读者在句末双字词呈现了约150 ms之时就已建立了句意; 可能存在比N400反映的加工更早的句意建构。     

发展性阅读障碍的遗传关联分析

发展性阅读障碍是一种遗传性很高的认知功能缺陷, 运用关联分析对其遗传机制进行研究是近年来的新趋势。从研究方法的视角可以将现有的关联分析研究归为以下三类：家系法研究、病例-控制法研究和数量性状关联分析研究。阅读障碍关联分析研究的新趋势主要体现在与全基因组扫描技术、神经成像技术以及基因功能研究的结合上, 促进了从“基因-大脑-行为”层面对发展性阅读障碍的遗传机制进行理解。     

不确定性、情绪对公正判断的影响

本研究以不确定管理模型为理论来源,采用实验法探讨了公正判断中的情绪效应。实验1采用2（两种情绪状态：愉快/愤怒）×4（四种结果：比自己多/一样多/比自己少/不知道）被试间设计。实验2采用2（两种情绪状态：愉快/愤怒）×3（三种程序：有发言权/外显无发言权/无发言权信息）被试间设计。分别考察了分配公正与程序公正判断中的情绪影响。结果发现：不确定性调节了情绪与公平判断之间的关系。当用于公平判断的外部信息不明确时,情绪充当了公平判断的线索。     

先天性音乐障碍的音高空间表征能力研究

利用音高空间表征任务、心理旋转任务和音高辨别任务,探讨先天性音乐障碍者音高空间表征能力、心理旋转加工能力和音高辨别能力。结果发现：先天性音乐障碍组音高空间表征任务标准差、心理旋转任务错误率和音高辨别任务错误率均显著高于控制组。 这些结果表明先天性音乐障碍并非音乐特异性障碍,而是音乐相关性障碍。     

阅读材料的呈现方式对儿童阅读活动的影响

本研究采用传统印刷文本、普通电子文本和超文本导航模式考察阅读材料的呈现方式对儿童阅读活动的影响.研究结果表明:(1)在三种呈现方式条件下,高阅读水平者的阅读成绩显著优于低水平者;女生成绩显著优于男生;(2)阅读材料的不同呈现方式对儿童阅读理解无显著影响;(3)在三种呈现方式中,儿童对超文本的正向评价要优于传统印刷文本和普通电子文本.这表明大部分儿童可以在短时间内接受,并熟悉非线性文本方式.     

视觉工作记忆中的加工与存储机制:回顾与思考

在视觉工作记忆的研究中,是否可能划分出视觉空间工作记忆和视觉物体工作记忆两个子系统还没有定论.子系统划分成立的基本前提是以特征为存储单位.当前关于存储单位的理论有特征理论、客体理论和双重存储等不同观点,多数视觉信息加工与存储机制的研究支持双重存储说.注意与视觉信息的加工和存储相互影响,因此,加工及存储机制的研究就要在具体的注意水平上进行.

Can an agent's false belief be corrected by an appropriate communication? Psychological reasoning in 18-month-old infants

Do 18-month-olds understand that an agent's false belief can be corrected by an appropriate, though not an inappropriate, communication? In Experiment 1, infants watched a series of events involving two agents, a ball, and two containers: a box and a cup. To start, agent1 played with the ball and then hid it in the box, while agent2 looked on. Next, in agent1's absence, agent2 moved the ball from the box to the cup. When agent1 returned, agent2 told her "The ball is in the cup!" (informative-intervention condition) or "I like the cup!" (uninformative-intervention condition). During test, agent1 reached for either the box (box event) or the cup (cup event). In the informative-intervention condition, infants who saw the box event looked reliably longer than those who saw the cup event; in the uninformative-intervention condition, the reverse pattern was found. These results suggest that infants expected agent1's false belief about the ball's location to be corrected when she was told "The ball is in the cup!", but not "I like the cup!". In Experiment 2, agent2 simply pointed to the ball's new location, and infants again expected agent1's false belief to be corrected. These and control results provide additional evidence that infants in the second year of life can attribute false beliefs to agents. In addition, the results suggest that by 18 months of age infants expect agents' false beliefs to be corrected by relevant communications involving words or gestures.     

Infants' reasoning about others' false perceptions

Prior research suggests that children younger than age 3 or 4 do not understand that an agent may be deceived by an object's misleading appearance. The authors asked whether 14.5-month-olds would give evidence in a violation-of-expectation task that they understand that agents may form false perceptions. Infants first watched events in which an agent faced a stuffed skunk and a doll with blue pigtails; the agent consistently reached for the doll, suggesting that she preferred it over the skunk. Next, while the agent was absent, the doll was hidden in a plain box, and the skunk was hidden in a box with a tuft of blue hair protruding from under its lid. Infants expected the agent to be misled by the tuft's resemblance to the doll's hair and to falsely perceive it as belonging to the doll. These and other results indicate that 14.5-month-old infants can already reason about agents' false perceptions.
