Mintz (2003) found that in English child-directed speech, frequently occurring frames formed by linking the preceding (A) and succeeding (B) word (A_x_B) could accurately predict the syntactic category of the intervening word (x). This has been successfully extended to French (Chemla, Mintz, Bernal, & Christophe, 2009). In this paper, we show that, as for Dutch (Erkelens, 2009), frequent frames in German do not enable such accurate lexical categorization. This can be explained by the characteristics of German including a less restricted word order compared to English or French and the frequent use of some forms as both determiner and pronoun in colloquial German. Finally, we explore the relationship between the accuracy of frames and their potential utility and find that even some of those frames showing high token-based accuracy are of limited value because they are in fact set phrases with little or no variability in the slot position. 相似文献

Phonetic variation has been considered a barrier that listeners must overcome in speech perception, but has been proved beneficial in category learning. In this paper, I show that listeners use within-speaker variation to accommodate gross categorical variation. Within the perceptual learning paradigm, listeners are exposed to p-initial words in English produced by a native speaker of French. Critically, listeners are trained on these words with either invariant or highly-variable VOTs. While a gross boundary shift is made for participants exposed to the variable VOTs, no such shift is observed after exposure to the invariant stimuli. These data suggest that increasing variation improves the mapping of perceptually mismatched stimuli. 相似文献

Referential gaze during situated language production and comprehension is tightly coupled with the unfolding speech stream (
[Griffin, 2001]
,
[Meyer et al., 1998]
and
[Tanenhaus et al., 1995]
). In a shared environment, utterance comprehension may further be facilitated when the listener can exploit the speaker’s focus of (visual) attention to anticipate, ground, and disambiguate spoken references. To investigate the dynamics of such gaze-following and its influence on utterance comprehension in a controlled manner, we use a human–robot interaction setting. Specifically, we hypothesize that referential gaze is interpreted as a cue to the speaker’s referential intentions which facilitates or disrupts reference resolution. Moreover, the use of a dynamic and yet extremely controlled gaze cue enables us to shed light on the simultaneous and incremental integration of the unfolding speech and gaze movement.We report evidence from two eye-tracking experiments in which participants saw videos of a robot looking at and describing objects in a scene. The results reveal a quantified benefit-disruption spectrum of gaze on utterance comprehension and, further, show that gaze is used, even during the initial movement phase, to restrict the spatial domain of potential referents. These findings more broadly suggest that people treat artificial agents similar to human agents and, thus, validate such a setting for further explorations of joint attention mechanisms. 相似文献

Although children with language impairments, including those associated with reading, usually demonstrate deficits in phonological processing, there is minimal agreement as to the source of those deficits. This study examined two problems hypothesized to be possible sources: either poor auditory sensitivity to speech-relevant acoustic properties, mainly formant transitions, or enhanced masking of those properties. Adults and 8-year-olds with and without phonological processing deficits (PPD) participated. Children with PPD demonstrated weaker abilities than children with typical language development (TLD) in reading, sentence recall, and phonological awareness. Dependent measures were word recognition, discrimination of spectral glides, and phonetic judgments based on spectral and temporal cues. All tasks were conducted in quiet and in noise. Children with PPD showed neither poorer auditory sensitivity nor greater masking than adults and children with TLD, but they did demonstrate an unanticipated deficit in category formation for nonspeech sounds. These results suggest that these children may have an underlying deficit in perceptually organizing sensory information to form coherent categories. 相似文献

The essay starts by questioning how the debate at the dam over the Hao River between Zhuang Zi and Hui Zi arose. It describes the source of ideas that led Zhuang Zi to speak on the enjoyment of the fish (yuzhile 鱼之乐) and points out that the meaning of the debate rests in bringing about the emergence of the true subject of “enjoyment.” It highlights this meaning by analyzing the essential content and value orientation of Zhuang Zi’s ideas on the joy of heaven (tian le 天乐) and perfect enjoyment (zhile 至乐). Following up on this thread, the essay goes further to analyze the true meaning of Zhuang Zi’s theory concerning the “great speech” of “non-speaking.” This essay holds that the debate is a parable, an external representation that unfolds an internal tension between two different levels contained within Zhuang Zi’s thought, rather than simply a debate between these two thinkers. 相似文献

采用混合实验设计, 句子-图片匹配范式和动态过程再现范式, 以包含静态情绪和动态变化情绪信息的句子为实验材料, 以被试对图片的反应时间为因变量指标, 通过不同时间间隔的设置以及不同的实验程序, 探讨了语言理解中静态情绪和动态情绪的心理模拟及其时间进程。结果表明:(1)被试对情绪的心理模拟与句中的语言描述一致, 情绪语境能够激活被试的经验模拟。(2)被试在句子理解加工的初期就能迅速、即时地模拟静态情绪信息, 且这种模拟具有一定的稳定性和持久性。(3)被试可以对动态变化的情绪进行动态的心理模拟, 不过这种模拟所需的时间要长, 是在句子理解加工的后期完成的。被试对不同情绪变化方向的句子模拟受到原情绪状态的影响, 当阅读由消极情绪向积极情绪变化的句子时, 由于被试固着于原来的消极情绪而发生了模拟积极情绪的困难。 相似文献

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。 相似文献
