双语经验降低言语产生过程中通达能力的研究综述

言语产生是指个体通过口头言语表达想法、感受,而通达过程是言语产生的关键过程。本文以言语产生的不同语言水平为线索,综合分析双语经验对言语产生过程中通达能力的影响,结果发现双语经验降低了言语产生中的通达效率。在此基础上,从跨语言干扰、语言使用频率和词汇量三个角度归纳双语通达劣势的原因。未来的研究应该考察双语经验对言语加工中不同方面的影响,并且对相关解释进行整合。     

《晏子春秋》战国中后期成书说补证——从一组常用词的演变着眼

词汇是语言三要素中最活跃的因素,它比语音、语法更能反映时代变化,通过考察《晏子春秋》中的＂酣、履、睡、布衣、诚信、夫子、枯槁、身体、声名、树木、学问＂等常用词所体现出的时代特征,足以为前人关于《晏子》成书于战国中后期的论断提供语言史上的有力支持。     

Is this still called a dog? 18‐month‐olds' generalization of familiar labels to unusual objects

In two experiments the flexibility of 18‐month‐olds' extension of familiar object labels was investigated using the intermodal preferential looking paradigm. The first experiment tested whether infants consider intact and incomplete objects as equally acceptable referents for familiar labels. Infants looked equally long at the intact and incomplete objects whether or not a label was presented. In the second experiment, infants were requested to find the referent of a target word among an incomplete target and an intact distracter or an intact target and an incomplete distracter. The incomplete objects were missing a large or small part. Infants looked longer at the incomplete target, even when large or small parts were deleted. Taken together, these findings suggest that infants do not hold a strong shape bias when generalizing familiar words. Copyright © 2002 John Wiley & Sons, Ltd.     

Age-of-acquisition effects in visual word recognition: evidence from expert vocabularies

Three experiments assessed the contributions of age-of-acquisition (AoA) and frequency to visual word recognition. Three databases were created from electronic journals in chemistry, psychology and geology in order to identify technical words that are extremely frequent in each discipline but acquired late in life. In Experiment 1, psychologists and chemists showed an advantage in lexical decision for late-acquired/high-frequency words (e.g. a psychologist responding to cognition) over late-acquired/low-frequency words (e.g. a chemist responding to cognition), revealing a frequency effect when words are perfectly matched. However, contrary to theories that exclude AoA as a factor, performance was similar for the late-acquired/high-frequency and early-acquired/low-frequency words (e.g. dragon) even though their cumulative frequencies differed by more than an order of magnitude. This last finding was replicated with geologists using geology words matched with early-acquired words in terms of concreteness (Experiment 2). Most interestingly, Experiment 3 yielded the same pattern of results in naming while controlling for imageability, a finding that is particularly problematic for parallel distributed processing models of reading.     

Playing with fire: effects of negative mood induction and working memory on vocabulary acquisition

We investigated the impact of emotions on learning vocabulary in an unfamiliar language to better understand affective influences in foreign language acquisition. Seventy native English speakers learned new vocabulary in either a negative or a neutral emotional state. Participants also completed two sets of working memory tasks to examine the potential mediating role of working memory. Results revealed that participants exposed to negative stimuli exhibited difficulty in retrieving and correctly pairing English words with Indonesian words, as reflected in a lower performance on the prompted recall tests and the free recall measure. Emotional induction did not change working memory scores from pre to post manipulation. This suggests working memory could not explain the reduced vocabulary learning in the negative group. We argue that negative mood can adversely affect language learning by suppressing aspects of native-language processing and impeding form-meaning mapping with second language words.     

Learning What to Remember: Vocabulary Knowledge and Children's Memory for Object Names and Features

Although young children can map a novel name to a novel object, it remains unclear what they actually remember about objects when they initially make such a name–object association. In the current study we investigated (1) what children remembered after they were initially introduced to name–object associations and (2) how their vocabulary size and vocabulary structure influenced what they remembered. As a group, children had difficulty remembering each of the features of the original novel objects. Further analyses revealed that differences in vocabulary structure predicted children's ability to remember object features. Specifically, children who produced many names for categories organized by similarity in shape (e.g. ball, cup) had the best memory for newly‐learned objects' features—especially their shapes. In addition, the more features children remembered, the more likely they were to retain the newly learned name–object associations. Vocabulary size, however, was not predictive of children's feature memory or retention. Taken together, these findings demonstrate that children's existing vocabulary structure, rather than simply vocabulary size, influences what they attend to when encountering a new object and subsequently their ability to remember new name–object associations.

Benefits of expressive writing and expressive talking about life goals

This study employed a 2 (writing vs. talking) × 2 (life goals vs. daily schedule) fully crossed, factorial design to examine whether health benefits might accrue for talking and/or writing about life goals. Participants assigned the life goals topic had fewer illness-related health center visits, regardless of mode of expression, compared to participants assigned the non-emotional topic. Counter to expectation, optimism did not moderate the effect of topic on illness-related health center visits. Participants in talking groups rated post-intervention mood as less negative than those in writing groups and participants rated talking about life goals as more difficult than writing about life goals.     

Atypicalities in sleep and semantic consolidation in autism

Sleep is known to support the neocortical consolidation of declarative memory, including the acquisition of new language. Autism spectrum disorder (ASD) is often characterized by both sleep and language learning difficulties, but few studies have explored a potential connection between the two. Here, 54 children with and without ASD (matched on age, nonverbal ability and vocabulary) were taught nine rare animal names (e.g., pipa). Memory was assessed via definitions, naming and speeded semantic decision tasks immediately after learning (pre‐sleep), the next day (post‐sleep, with a night of polysomnography between pre‐ and post‐sleep tests) and roughly 1 month later (follow‐up). Both groups showed comparable performance at pre‐test and similar levels of overnight change on all tasks; but at follow‐up children with ASD showed significantly greater forgetting of the unique features of the new animals (e.g., pipa is a flat frog). Children with ASD had significantly lower central non‐rapid eye movement (NREM) sigma power. Associations between spindle properties and overnight changes in speeded semantic decisions differed by group. For the TD group, spindle duration predicted overnight changes in responses to novel animals but not familiar animals, reinforcing a role for sleep in the stabilization of new semantic knowledge. For the ASD group, sigma power and spindle duration were associated with improvements in responses to novel and particularly familiar animals, perhaps reflecting more general sleep‐associated improvements in task performance. Plausibly, microstructural sleep atypicalities in children with ASD and differences in how information is prioritized for consolidation may lead to cumulative consolidation difficulties, compromising the quality of newly formed semantic representations in long‐term memory.

家庭读写环境与儿童接受性词汇发展关系的元分析

家庭读写环境(home literacy environment, HLE)与儿童接受性词汇(receptive vocabulary)发展的关系一直备受关注,但HLE内涵不清、各指标效应值强度不明,以及近年来两者关系差别较大等问题极大地限制了人们对该领域的认识。本文运用元分析技术对近30年国内外84篇相关实证研究进行分析。结果显示：HLE与儿童接受性词汇发展为中等程度正相关(r=0.31)。针对年代、文化背景、儿童年龄以及测量方法的调节效应检验表明：HLE效应值随年代发展显著降低,但其核心指标亲子阅读频率的效应值基本稳定;评估HLE的问卷法和现场观察法效应值无差异,但评估亲子阅读频率的书目清单法效应值显著高于问卷法。未见文化背景和儿童年龄的显著调节作用,原因值得进一步探究。后续研究应完善HLE的概念框架,更关注社会经济及文化视角下的概念建构以及测量改进。
