Momentum in Child Compliance and Opposition

Several event-dependent properties of child-mother interactions were studied to investigate momentum in child oppositional and compliant behavior. It was hypothesized that: (a) compared to an episode of child opposition, an episode of child compliance would be related to an increased likelihood of subsequent child compliance, and (b) the association between a target episode of child opposition and the likelihood of subsequent compliance or opposition would be mediated by the history of the dyadic interaction. These hypotheses were supported. In addition, the presence of interactional sequences predictive of child compliance was inversely related to mother dysphoria and unrelated to mother-reported child externalizing behavior disorder symptoms. Discussion focuses on antecedent interactional patterns as determinants of future child behavior.     

Influence of vowel context on the audio‐visual speech perception of voiced stop consonants

The work reported here investigated whether the extent of McGurk effect differs according to the vowel context, and differs when cross‐modal vowels are matched or mismatched in Japanese. Two audio‐visual experiments were conducted to examine the process of audio‐visual phonetic‐feature extraction and integration. The first experiment was designed to compare the extent of the McGurk effect in Japanese in three different vowel contexts. The results indicated that the effect was largest in the /i/ context, moderate in the /a/ context, and almost nonexistent in the /u/ context. This suggests that the occurrence of McGurk effect depends on the characteristics of vowels and the visual cues from their articulation. The second experiment measured the McGurk effect in Japanese with cross‐modal matched and mismatched vowels, and showed that, except with the /u/ sound, the effect was larger when the vowels were matched than when they were mismatched. These results showed, again, that the extent of McGurk effect depends on vowel context and that auditory information processing before phonetic judgment plays an important role in cross‐modal feature integration.     

语篇语境对句子理解的影响：来自N400的证据

N400作为语义违反的特异性ERP组分,其波幅反映了语义整合加工过程的难度,因此可将其作为研究语篇语境意义建构过程的一项重要指标。语篇语境可分为语言语境和非语言语境。前人一系列基于语篇水平的N400研究表明,从语义的角度上看,语言语境对句子理解具有制约和协调作用,其机制涉及词汇语义启动、场景适宜性、文字内容信息以及因果推理等方面;非语言语境对句子理解具有制约和补充作用,但其机制尚不明确。两种不同来源的语义信息在实时理解中是同时得到加工的     

句子理解过程中词类加工的功能性质

句法优先理论假设词类加工功能上优先于语义、动词论元结构和话语信息加工。来自德语和法语的证据显示, 词类违反阻断语义整合和动词论元结构加工, 因而词类优先于语义和动词论元结构。关于词类加工在功能上是否优先于话语信息加工, 尚无来自任何语言的证据。汉语证据尽管显示词类并不优先于语义, 但未充分讨论任务因素的影响。将来研究有必要使用ERP技术和违反范式, 从语义整合、动词论元结构加工和话语水平加工等多个层面, 同时操纵词类的正确性和非句法因素, 考察句法特性上与德语和法语不同的语言, 如汉语和韩语。这方面研究将有助于洞察一个语言的语言学特性如何制约或调整词类加工的功能性质。     

Demonstrating the effect of context on order effects for an army air defense task using the patriot simulator

The results reported herein support the hypotheses that (1) situation-specific, contextual features of a task can cause people to use explanation-based reasoning (Pennington and Hastie, 1993); (2) such reasoning can cause experienced personnel, both individually and in two-person teams, to reinterpret the meaning of the same information when it is presented in two different ordered sequences; and (3) the result will be primacy or recency (or no) effects depending on whether the most recent conflicting information can be explained away or not, respectively. These results extend the belief-adjustment model proposed by Hogarth and Einhorn (1992), which does not address information reinterpretations, and always predicts recency effects for an evaluation task with a short series of conflicting information. More generally, the results demonstrate the importance of situation-specific, contextual features in understanding judgment processes. © 1997 John Wiley & Sons, Ltd.     

阅读中自然学习生词的实验研究

本研究对儿童阅读时从语境中自然学习生词的过程及其多个影响因素进行了探讨。301名三、五年级小学生参加了实验。首先要求他们阅读文章,然后测验他们对文章中生词的知识。本研究在不同年级和能力的儿童中都发现了显著的自然学习效应。结果还表明,词的概念难度、词结构的语义透明度、语境线索强度和儿童课外阅读量对儿童的自然学习有重要影响。     

医学AI道德主体地位的哲学批判

医学人工智能(artificial intelligence, AI)是否能够成为道德主体而承担道德责任,关键要从哲学上辨析医学AI的感受性意识和意向性行为是否可能。意向性因果关系可以论证医学AI无法获得感受性意识和自由意志,因而不可能成为完全的道德主体;但在世界语境中,医学AI可以通过算法模拟表征派生的意向性意识,表现为有限的道德主体行为,这一功能完全由科研设计决定,因而可以向相关科研人员或机构追溯替代责任;在交流语境中,医学AI因“感受性缺失”不具有内在的意向性意识,因而不能有效交流并做出正确的医学判断,应由相关医务人员或机构承担替代责任。

     

Cue effectiveness in communicatively efficient discourse production

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units affect speakers' preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.     

中国背景下员工建言行为结构及中庸思维对其的影响

企业的自主创新离不开员工的自发性和创造性, 员工建言行为研究因此愈加受到重视。本研究拟探索中国背景下企业员工建言行为的结构(研究一), 并检验中国人的典型思维特征－中庸思维与中国背景建言行为的关系(研究二)。研究一通过对长三角地区30名企业员工的访谈提取建言行为关键事件, 编制初始问卷, 再通过对159名被试的探索性因素分析, 抽取出顾全大局式和自我冒进式两个建言行为维度; 另一批159名被试的验证性因素分析结果进一步证实了该结构。研究二以278份配对员工为样本, 层次回归分析结果表明, 中庸思维与顾全大局式建言存在正相关, 与自我冒进式建言存在负相关, 且授权对中庸思维与两类建言行为之间关系存在着调节作用。
