中-英双语者英语命名图片的一致性

选用中-英双语者对Snodgrass和Vanderwart的标准图片库中的224张图片进行了英语(第二语言)命名一致性研究,最后得到了131张图片的英语命名一致性百分数、概念一致性百分数及H值.建立了这些图片的英语命名一致性常模.本研究还考察了图片命名一致性与图片命名反应时和错误率的关系,结果发现,H值、命名一致性百分数及概念一致性百分数与图片命名反应时、错误率之间均呈现显著的相关,其中命名一致性百分数和概念一致性在预测图片命名反应时和错误率时起重要作用.     

记叙文中时间信息的事件边界效应

运用视知觉研究中经典的事件切割程序,探讨记叙文中时间信息的事件边界效应.结果发现记叙文中的时间信息会被读者外显地知觉为事件边界,并且,跨度长的时间信息比跨度短的时间信息更易于被知觉为事件边界.这和视知觉研究中的发现是一致的.研究在一定程度上支持了记叙文理解过程中情境模型建构的过程依赖类似于事件知觉中所发现的切割过程的观点,为知觉研究和认知研究领域提供了可供沟通的实证支持.     

音乐与语言的认知神经科学研究进展

回顾了近年来对音乐与语言的认知神经科学的研究结果.神经影像学研究表明音乐与语言可能拥有一些共同的神经机制;而对脑损伤病人的研究则表明两者可能同时拥有分离的、各自独立的神经基础.文章对这两类研究做了总结和比较,探讨了相关的理论模型,并对今后的研究趋势作出了展望.

ACQUISITION OF MANDS AND TACTS WITH CONCURRENT ECHOIC TRAINING

Previous studies have identified a number of effective teaching procedures to increase verbal behavior in individuals with developmental disabilities. However, few studies have evaluated modifications of treatment procedures when children fail to acquire communication skills. In the present investigation, a 4‐year‐old boy with autism failed to acquire unprompted mands and tacts during mand‐only and tact‐only training. Results indicated that combining echoic training with mand or tact training increased unprompted manding and tacting.     

The metamorphosis of the statistical segmentation output: Lexicalization during artificial language learning

This study combined artificial language learning (ALL) with conventional experimental techniques to test whether statistical speech segmentation outputs are integrated into adult listeners’ mental lexicon. Lexicalization was assessed through inhibitory effects of novel neighbors (created by the parsing process) on auditory lexical decisions to real words. Both immediately after familiarization and post-one week, ALL outputs were lexicalized only when the cues available during familiarization (transitional probabilities and wordlikeness) suggested the same parsing (Experiments 1 and 3). No lexicalization effect occurred with incongruent cues (Experiments 2 and 4). Yet, ALL differed from chance, suggesting a dissociation between item knowledge and lexicalization. Similarly contrasted results were found when frequency of occurrence of the stimuli was equated during familiarization (Experiments 3 and 4). Our findings thus indicate that ALL outputs may be lexicalized as far as the segmentation cues are congruent, and that this process cannot be accounted for by raw frequency.     

Imitation of body postures and hand movements in children with specific language impairment

Within the domain-general theory of language impairment, this study examined body posture and hand movement imitation in children with specific language impairment (SLI) and in their age-matched peers. Participants included 40 children with SLI (5 years 3 months to 6 years 10 months of age) and 40 children with typical language development (5 years 3 months to 6 years 7 months of age). Five tests were used to examine imitation and its underlying cognitive and motor skills such as kinesthesia, working memory, and gross motor coordination. It was hypothesized that children with SLI show a weakness in imitation of body postures and that this deficit is not equally influenced by the underlying cognitive and motor skills. There was a group effect in each cognitive and motor task, but only gross motor coordination proved to be a strong predictor of imitation in children with SLI. In contrast, hand movement imitation was strongly predicted by performance in the Kinesthesia task in typically developing children. Thus, the findings show not only that children with SLI performed more poorly on the imitation tasks than their typically developing peers but also that the groups’ performances showed qualitative differences. The results of the current study provide additional support to the view that the weaknesses in children with SLI are not limited to the verbal domain.     

Kindergarten literacy assessment of English Only and English language learner students: An examination of the predictive validity of three phonemic awareness measures

The study assessed the ability of English phonemic awareness measures to predict kindergarten reading performance and determine factors that contributed to growth trajectories on those measures for English Only (EO) and English language learner (ELL) students. Using initial sound fluency (ISF), phoneme segmentation fluency (PSF), and a combined phoneme segmentation task (CPST), students' beginning of kindergarten scores were used to predict end-of-kindergarten Nonsense Word Fluency (NWF) and reading (WRMT-R/NU). Regression analyses revealed that ISF and CPST early in kindergarten predicted variance in NWF and WRMT-R/NU. PSF did not predict reading performance over ISF or CPST. While gender was a significant factor in the growth curves across the measures, results revealed no significant difference for EO and ELL students.
