Une base de l’émotionalité (valence,arousal, catégories) de 1286 mots français selon l’âge (EMA)

Introduction/aim

Several studies have shown that the effects of word emotionality on its processing depend on both its valence and its arousal. Such effects also varied with age. However, in French, there is no norm providing both valence and arousal estimates for words not directly referring to an emotion. That was the aim of this study. Moreover, the base of word emotionality according to age (EMA) we propose here provides categorization for each word in basic emotional subcategories.

Impact of contextual constraint on vocabulary acquisition in reading*

The current study investigated the influence of contextual constraint (strong versus moderate) on incidental vocabulary acquisition in reading, as eye movements of adult skilled readers were monitored. Surprise post-tests followed the reading session, and eye movement behaviour was directly connected to retention data. Longer and more frequent reading/rereading was associated with trials containing a novel target (rather than a known control), and unique patterns of connective rereading between constraint conditions were observed. For reading measures reflecting target word processing and connecting target with context, fixations were generally longer and more frequent for moderate constraint than for strong. The exception was in rereading of informative context, which was generally longer for strong constraint. More and longer fixations while connecting novel targets with informative context proved critical for novel word retention, significantly so for moderate constraint but not for strong, based on eye movement data associated with memory for novel word stimuli.     

Dominant structure of word meanings moderates ageing-related decline in visual figure discrimination

This is a follow-up study to Tammik and Toomela [(2013). Relationships between visual figure discrimination, verbal abilities, and gender. Perception, 42, 971984] which established a correlational relationship between the propensity to use scientific as opposed to everyday concepts (as distinguished by L. Vygotsky) and visual figure discrimination. The purpose of the current study was to test a further prediction derived from Vygotskys theory in the context of ageing postponed start but faster rate of cognitive decline for scientific conceptual thinkers which is characteristic of cognitive reserve [Stern, Y.(2009). Cognitive reserve. Neuropsychologia, 47, 20152028]. The emergence of such a pattern with age was investigated by extending the original sample of 428 participants up to age 70 with additional 119 participants older than 70 years. The hypothesis was tested with piecewise (segmented) and local polynomial (loess) regression models and was confirmed.     

自闭症谱系障碍儿童在多重线索下习得词语的眼动研究

本文利用眼动追踪技术在基线、一致和矛盾3种实验条件下考察感知觉线索和社会性线索在自闭症谱系障碍儿童词语习得中的相对作用。行为数据结果表明, 此类儿童在矛盾条件下选择枯燥物体作为新异词语的所指对象, 这说明社会性线索较之于感知觉线索具有优势作用; 而他们在基线和一致条件下选择有趣物体作为新异词语的所指对象, 且一致条件的词语习得成绩优于基线条件, 这说明社会性线索较之于感知觉线索具有促进作用。眼动数据结果表明, 此类儿童在脸部注视模式和视线追随行为上与普通儿童存在差异。这说明, 虽然社会性线索在此类儿童与普通儿童的词语习得中具有相同的相对作用, 但他们获取社会性信息的方式与普通儿童存在差异。     

不同情绪效价的DRM词表对错误记忆的影响

请49名在校大学生对自编的36个具有不同情绪效价的DRM词表进行评定,再以60名在校大学生为实验对象考察不同情绪效价的DRM词表对错误记忆的影响。结果发现,(1) 负性和中性DRM词表产生的错误记忆量显著高于正性DRM词表;(2) 被试在“记得/知道/猜测”判断上对负性和中性词表的关键诱饵倾向于“知道”,而对正性词表的关键诱饵更倾向于“记得”。结果表明,DRM词表本身所具有的情绪与人为诱发的情绪,对错误记忆的影响具有不同的性质和特点。     

Development of hot and cool executive function during the transition to adolescence

This study examined the development of executive function (EF) in a typically developing sample from middle childhood to adolescence using a range of tasks varying in affective significance. A total of 102 participants between 8 and 15 years of age completed the Iowa Gambling Task, the Color Word Stroop, a Delay Discounting task, and a Digit Span task. Age-related improvements were found on all tasks, but improvements on relatively cool tasks (Color Word Stroop and Backward Digit Span) occurred earlier in this age range, whereas improvements on relatively hot tasks (Iowa Gambling Task and Delay Discounting) were more gradual and occurred later. Exploratory factor analysis indicated that performance on all tasks could be accounted for by a single-factor model. Together, these findings indicate that although similar abilities may underlie both hot and cool EF, hot EF develops relatively slowly, which may have implications for the risky behavior often observed during adolescence. Future work should include additional measures to characterize more intensively the development of both hot and cool EF during the transition to adolescence.     

Theories of spoken word recognition deficits in aphasia: evidence from eye-tracking and computational modeling

We used eye-tracking to investigate lexical processing in aphasic participants by examining the fixation time course for rhyme (e.g., carrot-parrot) and cohort (e.g., beaker-beetle) competitors. Broca’s aphasic participants exhibited larger rhyme competition effects than age-matched controls. A re-analysis of previously reported data (Yee, Blumstein, & Sedivy, 2008) confirmed that Wernicke’s aphasic participants exhibited larger cohort competition effects. Individual-level analyses revealed a negative correlation between rhyme and cohort competition effect size across both groups of aphasic participants. Computational model simulations were performed to examine which of several accounts of lexical processing deficits in aphasia might account for the observed effects. Simulation results revealed that slower deactivation of lexical competitors could account for increased cohort competition in Wernicke’s aphasic participants; auditory perceptual impairment could account for increased rhyme competition in Broca’s aphasic participants; and a perturbation of a parameter controlling selection among competing alternatives could account for both patterns, as well as the correlation between the effects. In light of these simulation results, we discuss theoretical accounts that have the potential to explain the dynamics of spoken word recognition in aphasia and the possible roles of anterior and posterior brain regions in lexical processing and cognitive control.     

比例推理的过度使用及其认知机制:一项发展性的负启动研究

从抑制控制模型出发,采用负启动范式探究过度使用比例推理的认知机制。研究包括3个实验,以小学生、中学生和大学生为被试,分别考察了抑制控制在解决缺值应用题、图片推理任务中的作用,以及数字比(整数比、非整数比)是否对抑制控制过程有影响。结果发现:小学生、中学生和大学生在两类实验任务中均出现了负启动效应,但负启动量不存在年级差异;在图片推理任务中,不同数字比类型下的负启动量具有显著差异。研究结果支持了抑制控制模型的观点,即成功解决问题不仅需要掌握问题的内在逻辑,更需要对不恰当策略进行抑制;在解决问题的过程中,无论是儿童、青少年还是成人都需要抑制控制的参与,三者在抑制控制效率上没有差异;数字比类型对抑制过程有影响,但仅限于图片推理问题。     

老年人与青年人阅读空格文本的注视位置效应

采用EyeLink2000眼动仪,以14名老年人和14名青年人为被试,探讨他们阅读空格汉语文本的注视位置效应.阅读材料分为正常无空格文本和词间空格文本两种.结果发现:(1)在阅读词间空格文本和正常无空格文本时,老年人与青年人都表现出单次注视的首次注视是位于词的中心,多次注视的首次注视是位于词的开头;(2)老年人阅读正常无空格文本时对词尾的注视概率显著低于词间空格文本,而青年人则没有差异.结果表明老年人与青年人在阅读空格文本时存在注视位置效应.     

Effect of Representational Distance Between Meanings on Recognition of Ambiguous Spoken Words

Previous research indicates that mental representations of word meanings are distributed along both semantic and syntactic dimensions such that nouns and verbs are relatively distinct from one another. Two experiments examined the effect of representational distance between meanings on recognition of ambiguous spoken words by comparing recognition of unambiguous words, noun–verb homonyms, and noun–noun homonyms. In Experiment 1, auditory lexical decision was fastest for unambiguous words, slower for noun–verb homonyms, and slowest for noun–noun homonyms. In Experiment 2, response times for matching spoken words to pictures followed the same pattern and eye fixation time courses revealed converging, gradual time course differences between conditions. These results indicate greater competition between meanings of ambiguous words when the meanings are from the same grammatical class (noun–noun homonyms) than when they are from different grammatical classes (noun–verb homonyms).
