Disentangling fast and slow attentional influences of negative and taboo spoken words in the emotional Stroop paradigm

Although the influence of the emotional content of stimuli on attention has been considered as occurring within trial, recent studies revealed that the presentation of such stimuli would also involve a slow component. The aim of the present study was to investigate fast and slow effects of negative (Exp. 1) and taboo (Exp. 2) spoken words. For this purpose, we used an auditory variant of the emotional Stroop paradigm in which each emotional word was followed by a sequence of neutral words. Replicating results from our previous study, we observed slow but no fast effects of negative and taboo words, which we interpreted as reflecting difficulties to disengage attention from their emotional dimension. Interestingly, while the presentation of a negative word only delayed the processing of the immediately subsequent neutral word, slow effects of taboo words were long-lasting. Nevertheless, such attentional effects were only observed when the emotional words were presented in the first block of trials, suggesting that once participants develop strategies to perform the task, attention-grabbing effects of emotional words disappear. Hence, far from being automatic, the occurrence of these effects would depend on participants' attentional set.     

中文双字词的表征与加工(上)

从研究背景、实验研究和理论观点等几方面对中文双字词的表征与加工的有关研究进行了总结,介绍和分析了常用的几种实验研究范式和有关的实验结论,并对两种主要的理论模型进行了比较。在此基础上提出了进一步研究所应注意的几个问题。     

封闭性知觉在大范围优先性中的特殊性

本文研究当封闭性作为被试分辨的图形性质时,空间位置不确定性和视野位置对大范围优先性有何影响。实验发现：（１）无论复合刺激呈现在视野的中央或外周．分辨复合刺激的整体性质的反应时（ＲＴ）比分辨局部性质的ＲＴ短,整体性质对分辨局部性质的反应有较强的干扰作用。相反,局部性质对分辨整体性质的反应的影响较小;（２）刺激位置的不确定对大范围优先性没有显著影响;（３）与周边刺激相比,分辨视野中央的复合刺激的ＲＴ较短,但整体性质的ＲＴ优势和对局部性质的干扰作用,不受刺激在视野中的位置的影响。这些实验结果揭示了封闭性知觉在大范围优先性中的特殊性。     

Response summation to a compound stimulus in a context of choice

Key pecks by two groups of pigeons were reinforced on concurrent schedules. For group Ē, pecks were reinforced during either a visual or an auditory stimulus; for group E, an additional, extinction component was available, during which both visual and auditory stimuli were absent. After training, both groups were given a compound test to measure preference among four stimuli, the three used in training plus a compound of the visual and auditory stimulus. Group E showed preference for the compound, emitting more pecks and spending more time in this stimulus than in other stimuli. Group Ē showed no preference between the compound and visual stimulus, nor between the auditory stimulus and the absence of both stimuli, but preferred the former pair over the latter pair of stimuli.     

Incidental teaching of language in the preschool

"Incidental teaching" denotes a process whereby language skills of labelling and describing are learned in naturally occurring adult-child interactions. In the present study, 15-min daily samples of the spontaneous speech of 11 children were recorded during free play over eight months of preschool. After incidental teaching of compound sentences, increases in unprompted use of compound sentences were seen for all the children, first directed to teachers, and then to children, in accordance with who attended to the children's requests for play materials. The incidental teaching procedure also stimulated spontaneous variety in speech, and appears to have general applicability to child learning settings.     

中文双字词Stroop现象实验研究

本研究在标准的 Stroop任务中引入中文双字颜色词 ,结果发现 :1无论是单字词还是双字词都产生了显著的 Stroop干扰效应和促进效应 ,双字词的反应时模式同单字词相同。这表明语言学意义上的中文词是一个知觉加工单元 ,无论它由一个字组成或由两个字组成。 2无论是单字词还是双字词 ,Stroop促进效应和干扰效应相同 ,相对于控制条件呈一种对称关系。这一结果同国外的有关发现不同 ,表明作为表意文字的汉字同西方拼音文字具有不同的信息加工特点。     

否定情绪词的具身动态模拟过程

实验1和实验2分别以“（不）+积极/消极情绪词”和“（不）+愤怒/悲伤情绪词”形式的情绪词语或否定短语作为实验材料,分别采取词-图匹配范式和趋近-回避范式,以否定加工的早期（250ms）和中后期（1000ms）两种探测时间,探讨否定对情绪词效价与动机维度加工是否符合否定的两步模拟假设。结果发现,否定情绪效价部分符合否定的两步模拟假设,早期以被否定的情绪状态模拟为主,即不高兴会首先激活高兴;中后期,否定消极词和积极词都被理解为积极;否定情绪动机维度并不符合否定的两步模拟假设,否定对愤怒与悲伤的趋近－回避的影响出现在否定加工中后期,否定改变愤怒的动机方向,由趋近变为回避,却没有改变悲伤的动机方向,悲伤仍表现为回避。本研究证明否定对情绪词的效价和动机维度部分符合两步模拟假设,否定情绪词有其特定的加工过程,各维度加工有所不同。     

Why Choo‐Choo Is Better Than Train: The Role of Register‐Specific Words in Early Vocabulary Growth

Across languages, lexical items specific to infant‐directed speech (i.e., ‘baby‐talk words’) are characterized by a preponderance of onomatopoeia (or highly iconic words), diminutives, and reduplication. These lexical characteristics may help infants discover the referential nature of words, identify word referents, and segment fluent speech into words. If so, the amount of lexical input containing these properties should predict infants’ rate of vocabulary growth. To test this prediction, we tracked the vocabulary size in 47 English‐learning infants from 9 to 21 months and examined whether the patterns of growth can be related to measures of iconicity, diminutives, and reduplication in the lexical input at 9 months. Our analyses showed that both diminutives and reduplication in the input were associated with vocabulary growth, although measures of iconicity were not. These results are consistent with the hypothesis that phonological properties typical of lexical input in infant‐directed speech play a role in early vocabulary growth.     

CHRISTOPHER SOUTHGATE'S COMPOUND THEODICY: PARALLEL SEARCHINGS

Christopher Southgate proposes that a theological response to the suffering that is built into an evolutionary world requires a compound evolutionary theodicy, made up of four interrelated theological positions. This article proposes a fourfold response to the suffering of nonhuman creation that parallels Southgate's compound theodicy. In its similarities and differences, it is offered in the spirit of a tribute to Christopher Southgate.
