3-6岁幼儿言语表达能力发展特点研究

本研究采用口语表述和运作表达两个实验探讨了3—6岁幼儿言语表达能力的发展特点。结果表明;幼口语表达和动作表现能力随年龄增长逐渐提高,3—5岁是幼儿口语表述能力发展的快速期。口语表述内容由可视的、外在的特征逐渐转向内在特征,呈现由固有属性向关系属性发展的趋势。幼儿期动作表达特点以发展核心动作并进行扩展为主。4岁是动作表达的转折时期。4岁和5岁是两种表达方式关系发展最密切的时期。     

语音超文本系统中锚点标记方式的比较研究

近年来。语音超文本系统中超链接锚点的标记方式成为该研究领域的一个热点问题。笔者在设计参数优化基础上对语音超文本系统中常见的两种超链接锚点标记方式——言语相关标记与非言语相关标记进行比较研究,旨在为语音超文本界面中超链接锚点标记的设计提供适宜的参数。实验在模拟的语音超文本系统中进行,以链接词检测率、句子理解正确率和主观评价作为评价绩效的指标,结果发现,(1)男女声变调的言语相关标记方式下对链接词的检测率和主观评价均优于全词标记和尾字标记两种非言语相关标记方式,但上述三种标记方式对句子理解均无显著影响;(2)采用非言语相关标记时,链接词在句中的位置显著影响其检测率。根据上述结果,笔者推荐男女声变调标记可作为语音超文本链接词标记的首选方式。     

Shyness,Self-regulation,and Cognitive Problem Solving in Typically Developing 4-year-olds: A Pilot Study

Because shy children are at risk for poor academic achievement, it is important to examine factors that contribute to variability in the relation between individual differences in shyness and cognitive functioning before school entry. The authors examined whether on-task facilitative private speech—a proxy of self-regulation—moderated the association between individual differences in shyness and performance on an executive function (EF) task in 52 typically developing 4-year-olds. They found that private speech interacted with shyness to predict performance on the EF task in girls but not in boys. More specifically, shyness was inversely related to EF task performance when girls used low amounts of regulatory private speech, but was positively related to performance when girls used high amounts of regulatory private speech. These preliminary findings are discussed in the context of implications for shy children in educational settings.     

“Freedom of speech requires actions”: Exploring the discourse of politicians convicted of hate-speech against Muslims

This study explores how politicians convicted of hate-speech against Muslims account for their actions in statements on their Facebook-pages as well as in reported interviews. Taking a critical discursive psychological perspective, the study examines the strategies through which the politicians discursively claim and resist various subject positions, thus managing to construct their hate-speech as everything from trivial mishaps to acts of virtue. The study examines the multifaceted dynamics of these constructions, and shows how elements from the Five Step Social Identity Model of the Development of Collective Hate are flexibly deployed in the discourse to serve distinct social and political purposes. By allowing the Social Identity and (critical) discursive approaches to challenge and develop each other, the study advances social psychological research on political communication and persuasion, and contributes to the debate on the boundaries between hate-speech and freedom of speech.     

Newborns are sensitive to multiple cues for word segmentation in continuous speech

Before infants can learn words, they must identify those words in continuous speech. Yet, the speech signal lacks obvious boundary markers, which poses a potential problem for language acquisition (Swingley, Philos Trans R Soc Lond. Series B, Biol Sci 364 (1536), 3617–3632, 2009). By the middle of the first year, infants seem to have solved this problem (Bergelson & Swingley, Proc Natl Acad Sci 109 (9), 3253–3258, 2012; Jusczyk & Aslin, Cogn Psychol 29 , 1–23, 1995), but it is unknown if segmentation abilities are present from birth, or if they only emerge after sufficient language exposure and/or brain maturation. Here, in two independent experiments, we looked at two cues known to be crucial for the segmentation of human speech: the computation of statistical co‐occurrences between syllables and the use of the language's prosody. After a brief familiarization of about 3 min with continuous speech, using functional near‐infrared spectroscopy, neonates showed differential brain responses on a recognition test to words that violated either the statistical (Experiment 1) or prosodic (Experiment 2) boundaries of the familiarization, compared to words that conformed to those boundaries. Importantly, word recognition in Experiment 2 occurred even in the absence of prosodic information at test, meaning that newborns encoded the phonological content independently of its prosody. These data indicate that humans are born with operational language processing and memory capacities and can use at least two types of cues to segment otherwise continuous speech, a key first step in language acquisition.     

Stress changes the representational landscape: evidence from word segmentation

Over the past couple of decades, research has established that infants are sensitive to the predominant stress pattern of their native language. However, the degree to which the stress pattern shapes infants' language development has yet to be fully determined. Whether stress is merely a cue to help organize the patterns of speech or whether it is an important part of the representation of speech sound sequences has still to be explored. Building on research in the areas of infant speech perception and segmentation, we asked how several months of exposure to the target language shapes infants' speech processing biases with respect to lexical stress. We hypothesize that infants represent stressed and unstressed syllables differently, and employed analyses of child-directed speech to show how this change to the representational landscape results in better distribution-based word segmentation as well as an advantage for stress-initial syllable sequences. A series of experiments then tested 9- and 7-month-old infants on their ability to use lexical stress without any other cues present to parse sequences from an artificial language. We found that infants adopted a stress-initial syllable strategy and that they appear to encode stress information as part of their proto-lexical representations. Together, the results of these studies suggest that stress information in the ambient language not only shapes how statistics are calculated over the speech input, but that it is also encoded in the representations of parsed speech sequences.     

想象、再现与重复--德里达对胡塞尔关于实在话语与想象话语之区分的解构及其意义

本文主要讨论了德里达对胡塞尔在《逻辑研究》中所作的关于“真实话语”与“想象话语”之区分的解构。在德里达看来,无论是真实话语还是想象话语,首先都是一种“本源的重复结构”。这种本源的重复比真实话语与想象话语的区分更古老,它是一切话语乃至一切符号的“共根”。本文详细梳理了德里达的解构过程和解构策略,并指出这种解构的最终目的是为了解构传统形而上学所确立的本原与替补的差异体系,由此揭示了这种解构对于西方形而上学的意义。     

Monologic and Dialogic Styles of Argumentation: A Bakhtinian Analysis of Academic Debates between Mainland China and Taiwan

This study applies the concept of reported speech advanced by the renowned Russian literary scholar Mikhail Bakhtin to compare the argumentative styles of Mainland China and Taiwan. These societies in question are considered by many scholars as sharing the same argumentative style. The study reports that the Mainland debaters more frequently than the Taiwanese debaters maintained the authenticity of the quotations cited from ancient Confucian sources, whereas Taiwanese debaters paraphrased more frequently. On the other hand, this difference cannot be found when debaters quoted from sources other than Ancient Confucians. The findings, according to Bakhtin, imply a contrast of monologic and dialogic tendencies toward authority, which results in a style difference between Mainland and Taiwan argumentation.     

Assessing automaticity in audiovisual speech integration: evidence from the speeded classification task

The McGurk effect is usually presented as an example of fast, automatic, multisensory integration. We report a series of experiments designed to directly assess these claims. We used a syllabic version of the speeded classification paradigm, whereby response latencies to the first (target) syllable of spoken word-like stimuli are slowed down when the second (irrelevant) syllable varies from trial to trial. This interference effect is interpreted as a failure of selective attention to filter out the irrelevant syllable. In Experiment 1 we reproduced the syllabic interference effect with bimodal stimuli containing auditory as well as visual lip movement information, thus confirming the generalizability of the phenomenon. In subsequent experiments we were able to produce (Experiment 2) and to eliminate (Experiment 3) syllabic interference by introducing 'illusory' (McGurk) audiovisual stimuli in the irrelevant syllable, suggesting that audiovisual integration occurs prior to attentional selection in this paradigm.
