语素意识在儿童汉语阅读中的作用

文章考察了语音意识、语素意识和命名速度在儿童汉语阅读中的作用。结果发现：语素意识和命名速度对汉字命名组词具有显著的预测作用;而语素意识和语音意识对同音字识别具有显著的预测作用。语素意识是唯一显著预测两种不同阅读任务的认知变量。对阅读障碍儿童所存在的缺陷进行分析,结果发现：76%的阅读障碍存在语素缺陷;相比之下,分别有43%和41%的阅读障碍存在语音缺陷和命名速度缺陷。结果表明汉语的语素意识在儿童阅读中具有重要作用,语素缺陷有可能成为儿童汉语阅读困难的主要原因。     

ASSESSMENT OF PREFERENCE FOR VARIED VERSUS CONSTANT REINFORCERS

One method that has been demonstrated to improve the effectiveness of reinforcement is stimulus (reinforcer) variation (Egel, 1980). Egel found that bar pressing increased and responding occurred more rapidly during varied reinforcement than during constant reinforcement when identical stimuli were used across phases for 10 individuals with autism. The purpose of the current investigation was to assess the preferences of 7 individuals for varied presentation of slightly lower quality stimuli relative to constant access to the highest quality stimulus. Varied presentation was preferred over constant reinforcer presentation with 4 participants, and the opposite was true for 2 participants. One participant did not demonstrate a preference. These results suggest that stimulus variation may allow less preferred reinforcers to compete effectively with a more highly preferred reinforcer for some individuals.     

汉语词汇语音中介效应的眼动研究

使用美国应用科学实验室生产的504型眼动仪,采用语音中介启动范式,对汉语词汇识别是否存在语音中介效应进行考察。结果发现：（1）被试对语音中介词的首次注视点持续时间、凝视时间均显著高于控制条件;（2）当语音中介词为低频词时,被试对语音中介启动词的总注视时间显著高于控制类型;（3）语音中介类型的正确率显著低于控制类型;（4）实验结果表明,汉语词汇识别中存在语音中介效应。     

中国香港双语儿童初步阅读能力与语音、文字加工关系的研究

采用音节检测、短时言语记忆、快速命名等语音加工任务和汉字、字母、数字等方向加工任务,探讨语音和文字加工在儿童初步阅读中的作用,116名6岁左右的香港双语儿童参加了测试。结果表明：语音加工能力是跨语言的比较稳定的因素,是预测汉语和英语阅读的较好指标;文字加工具有特异性．即汉字方向加工只能预测汉语阅读,字母方向加工则预测英语阅读。     

双语儿童语音意识与词汇认读关系的研究

通过平行语音和词汇加工任务。对64名双语儿童英汉两种语言语音意识和词汇认读能力进行了双向测查。结果表明：双语儿童在两种语言不同语音意识和词汇认读之间存在跨语言的多重相关;在对其英语和汉语词汇认读能力的预测中,汉语音节辨认和英语音素识别均为重要的指标,表明语音意识对词汇认读能力具有跨语言的双向预测作用。     

小学儿童汉语语音意识的发展

运用纵向与横向研究探讨了小学一年级儿童汉语语音意识发展的过程和小学一、三、五年级儿童汉语语音意识的年级差异。结果表明。在汉语语音意识各任务上,刚入学儿童的反应都处于随机的水平,其后声调意识先于其他语音意识而发展,其次为首音-韵脚意识,音位意识发展得最迟。     

Amorçage syntaxique de structures syntaxiques complexes chez des enfants de maternelle en français oral

Several studies have revealed syntactic priming effects in 3- and 4-year-old children. However, the eventual role of syntactic priming in the learning of complex syntactic structures has rarely been investigated. The current paper investigated in young children the effect of being exposed to complex syntaxic structures employed by adults. In this perspective, we used a syntactic priming paradigm with kindergarten children. It aimed at studying whether children would in turn spontaneously produce more complex syntactic structures, compared to another condition with no prior exposure to such complex sentences. We determined the cognitive and linguistic factors susceptible to explain inter-individual differences in syntactic priming. The finding suggests that syntactic priming procedure can to be used to train young children to produce complex syntactic structures. Lexical knowledge and short-term phonological memory could explain inter-individual differences in the use of these complex syntactic structures. These results are discussed at the theoretical level, but also in terms of possible educational implications.     

儿童英汉口语词汇知识与英语语音意识的关系

以120名母语为汉语的四、五年级小学儿壹为被试.探讨英语和母语口语词汇知识与英语语音意识的关系.结果表明: (1)英语和母语口语词汇知识与英语语音意识之间存在密切关系. (2)英语口语词汇产生对英语音节、首音一韵脚和音位意识具有显著的独立预测作用,英语口语词汇理解对英语语音意识的独立贡献性不显著. (3)汉语口语词汇产生对英语音节意识具有显著的预测作用,汉语口语词汇理解对英语音位意识具有显著的预测作用;汉语口语词汇产生既可以直接作用于英语音节意识,也可以通过汉语语音意识的中介发挥间接作用:汉语口语词汇理解则完全通过汉语语音意识和英语口语词汇产生的中介间接作用于英语旨位意识.     

Mapping from Sound to Meaning: Reduced Lexical Activation in Broca''s Aphasics

Recent studies of lexical access in Broca's aphasics suggest that lexical activation levels are reduced in these patients. The present study compared the performance of Broca's aphasics with that of normal subjects in an auditory semantic priming paradigm. Lexical decision times were measured in response to word targets preceded by an intact semantically related prime word ("cat"-"dog"), by a related prime in which one segment was acoustically altered to produce a poorer phonetic exemplar ("c*at"-"dog"), and by a semantically unrelated prime ("ring"-"dog"). The effects of the locus of the acoustic distortion within the prime word (initial or final position) and the presence of potential lexical competitors ("cat" --> /gaet/versus "coat" --> "goat") were examined. In normal subjects, the acoustic manipulations produce a small, short-lived reduction in semantic facilitation irrespective of the position of the distortion in the prime word or the presence of a voiced lexical competitor. In contrast, Broca's aphasics showed a large and lasting reduction in priming in response to word-initial acoustic distortions, but only a weak effect of word-final distortions on priming. In both phonetic positions, the effect of distortion was greater for prime words with a lexical competitor. These findings are compatible with the claim that Broca's aphasics have reduced lexical activation levels, which may result in a disruption of the bottom-up access of words on the basis of acoustic input as well as increased vulnerability to competition between acoustically similar lexical items.     

Divine Omniscience: Is God's Foreknowledge at Risk in the Context of Contemporary Science?

Abstract

Does quantum indeterminacy threaten the classical theological doctrine of divine omniscience? Certain popular interpretations of quantum physics have challenged conventional ways of thinking about time and space, being and becoming. Consequently, the traditional doctrine that God knows all things, including future contingent events, has recently come under debate. This paper explores how the way we think about time affects the way we think about God's relation to time. Theologians need to be careful when appropriating scientific theories in their theological reflections because interpretations of those theories often bring along unnecessary metaphysical presuppositions. Using an interpretation of special relativity that focuses on the Lorentz transformation, this paper shows that modern physics does not truly challenge the doctrine of divine foreknowledge. In fact, modern physical theories can actually deepen theological reflection on the classical doctrine of divine omniscience.
