变形汉字的结构方式和笔画数效应

曾捷英等提出并采用了汉字通透性概念解释汉字识别中的字形属性效应,例如笔画数效应、笔画类型效应和结构方式效应。在有关研究中采用的主要实验方法是在速示、重复速示、非速示、时间或空间微观发生等条件下要求被试命名汉字。该研究将采用新的实验方法,即在呈现变形汉字1200ms后要求被试报告识别内容。结构方式和笔画数两种字形属性为研究对象。实验结果表明存在着常规的结构方式效应和笔画数效应,尤为重要的是观察到了逆转的结构方式效应。客观计算出的汉字通透性可以合理地解释这些效应。该研究和先前研究部分证明了关于汉字字形知觉的一个重要假设：汉字通透性是形成各种字形属性效应的基本或主导原因。字形属性对汉字识别的影响可以归结为通透性的影响,这称之为通透性中介假设。     

矩阵完成问题的项目生成研究

依据Embretson提出的认知设计系统方法,设计并编制了矩阵完成问题的项目生成系统,实际生成了矩阵完成问题测验。探讨矩阵测验与瑞文测验的关系,以及认知模型对矩阵问题的难度和区分度的预测能力。结果表明所设计的认知模型对矩阵项目的性能参数有一定的预测能力,生成的矩阵测验与瑞文测验有基本相同的心理测量属性。可以使用该系统生成的矩阵项目来测量被试的抽象推理能力。     

数目和呈现方式对时距估计的影响

采用口头估计的方法,考察刺激的数目和呈现方式对时距估计的影响。以时距估计的平均值、准确性和变异性为指标,结果表明：（1）数目多少影响时距估计的平均值和准确性,数目少引起低估,数目多导致高估,数目多少与时距长度一致时,准确性高。（2）呈现方式影响时距估计的变异性,同时呈现时变异性最大;（3）数目和呈现方式的交互作用显著,固定频率和变化频率呈现时,数目影响时距估计。（4）随着时距的增加,时距估计的平均值由高估向低估,准确性由低向高发展。这表明时距和数目在心理表征上存在连接,数目和呈现方式在不同的时间范围内影响     

Play enhances visual form perception in infancy–an active training study

Motor experiences and active exploration during early childhood may affect individual differences in a wide range of perceptual and cognitive abilities. In the current study, we suggest that active exploration of objects facilitates the ability to process object forms and magnitudes, which in turn impacts the development of numerosity perception. We tested our hypothesis by conducting a preregistered active exploration intervention with 59 8‐month‐old infants. The minimal intervention consisted of actively playing with and exploring blocks once a day for 8 weeks. In order to control for possible training effects on attention, we used book reading as a control condition. Pre‐ and post‐test assessments using eye‐tracking showed that block play improved visual form perception, where infants became better at detecting a deviant shape. Furthermore, using three control tasks, we showed that the intervention specifically improved infants' ability to process visual forms and the effect could not be explained by a domain general improvement in attention or visual perception. We found that the intervention did not improve numerosity perception and suggest that because of the sequential nature of our hypothesis, a longer time frame might be needed to see improvements in this ability. Our findings indicate that if infants are given more opportunities for play and exploration, it will have positive effects on their visual form perception, which in turn could help their understanding of geometrical concepts.     

“一”人代言的魅力：品牌代言人数如何影响消费者的品牌态度

有的品牌仅邀请一位名人代言, 而有的品牌由多位名人代言, 那么一人代言还是多人代言会更有效?为了回答该问题, 研究基于形象转移视角和单人积极偏差, 深入探究了品牌代言人数因素(一位代言人vs.多位代言人)对品牌态度的影响机制和边界条件。研究发现：相比品牌多人代言, 品牌单人代言使消费者的品牌态度更高。原因在于消费者与一位(vs.多位)品牌代言人的自我-品牌联结更紧密, 进而促进品牌态度。该品牌代言人效应仅局限于象征型产品, 而对于非身份象征型产品, 品牌单人代言(vs.品牌多人代言)对品牌态度无显著差异。此外, 当多位品牌代言人为一个团体时, 品牌代言人数效应将被逆转, 即品牌多人代言(vs.品牌单人代言)对品牌态度的影响更高。     

学习、笔画和线索注视时间对汉字知觉干扰效应的影响

采用经高斯模糊技术处理的汉字,以命名为任务,实验一考察了事先学习以及笔画数、实验二考察了笔画数和线索注视时间对干扰效应的影响.结果发现:1.无论是否学习,汉字识别均存在于扰效应;2.无论汉字笔画多少均存在干扰效应;3.模糊线索的注视时间足够长久之后不再影响干扰效应.这些结果似乎表明当激活超过一定水平时,和汉字激活水平有关的因素对知觉干扰效应不再起作用.     

From exemplar to grammar: a probabilistic analogy-based model of language learning

While rules and exemplars are usually viewed as opposites, this paper argues that they form end points of the same distribution. By representing both rules and exemplars as (partial) trees, we can take into account the fluid middle ground between the two extremes. This insight is the starting point for a new theory of language learning that is based on the following idea: If a language learner does not know which phrase-structure trees should be assigned to initial sentences, s/he allows (implicitly) for all possible trees and lets linguistic experience decide which is the "best" tree for each sentence. The best tree is obtained by maximizing "structural analogy" between a sentence and previous sentences, which is formalized by the most probable shortest combination of subtrees from all trees of previous sentences. Corpus-based experiments with this model on the Penn Treebank and the Childes database indicate that it can learn both exemplar-based and rule-based aspects of language, ranging from phrasal verbs to auxiliary fronting. By having learned the syntactic structures of sentences, we have also learned the grammar implicit in these structures, which can in turn be used to produce new sentences. We show that our model mimicks children's language development from item-based constructions to abstract constructions, and that the model can simulate some of the errors made by children in producing complex questions.     

Numerical distance effect in developmental dyscalculia

Children in third and fourth grades suffering from developmental dyscalculia (DD) and typically developing children were asked to compare numbers to a standard. In two separate blocks, they were asked to compare a number between 1 and 9 to 5, or a two-digit number between 10 and 99 to 55. In the single-digit comparisons, DD children were comparable to the control group in reaction time but showed a difference in error rates. In the two-digit number comparisons, DD children presented a larger distance effect than the controls. In addition, they were more influenced by the problem size than controls were. Assuming an analog representation of quantities, this suggests that quantities are less differentiated in those with DD than in typically developing children.     

Argumentative Ordering of Utterances for Language Generation in Multi-party Human–Computer Dialogue

In trying to control various aspects concerning utterance production in multi-party human–computer dialogue, argumentative considerations play an important part, particularly in choosing appropriate lexical units so that we fine-tune the degree of persuasion that each utterance has. A preliminary step in this endeavor is the ability to place an ordering relation between semantic forms (that are due to be realized as utterances, by the machine), concerning their persuasion strength, with respect to certain (explicit or implicit) conclusions. Thus, in this article, we propose a mechanism for assessing utterances, in terms of their argumentative force. The framework designed conflates insights from Asher and Lascarides’ SDRT (“Segmented Discourse Representation Theory”), and from Anscombre and Ducrot’s AT (“Argumentation Theory”). These mechanisms are included in a language generation component of a multi-party dialogue system for book reservation applications (i.e., a “virtual librarian”), and thus evaluated via typical human–machine conversations.

诊断认知策略的几何类比推理测验题的特征及其编制研究

该文在新一代测验理论的视角下,以几何类比推理测验为研究对象,以认知策略的诊断为目的,研究更能引发被试的规则构建策略或选项剔除策略的项目的特征。研究结果表明,项目中元素数量是影响被试使用规则构建策略或选项剔除策略的关键因素,元素数量越多时越倾向于用规则构建策略,而元素数量越少时倾向于用选项剔除策略。研究结果可直接用于测验设计,使得测验能更多在某一策略的框假下分析描述被试特征。
