语义关联的注意捕获——来自线索化范式的证据

采用线索化范式, 操作性地建立线索和靶子的语义关联, 考察语义关联对注意捕获的影响。实验1采用特征线索意义靶子的形式, 建立某一特定语义水平的注意控制定势, 发现线索靶子语义一致时线索捕获注意, 线索靶子语义不一致时同样的线索失去捕获注意的能力。实验2随机呈现线索颜色和靶子汉字, 建立两种语义概念的注意控制定势, 发现所有的线索都出现了捕获效应, 而不论其在某一具体试次中是否与靶子意义一致。实验3交换了线索与靶子的属性及概念, 采用意义线索特征靶子的形式, 结果与实验1一致。这些结果表明, (1)语义关联的注意捕获符合关联性的无意注意定向假说, 刺激的捕获能力受当前的注意控制定势调节; (2)由语义概念激活的知觉表征在调节空间注意分配上与其自身相比形式相同, 但程度有所下降; (3)知觉特征水平的注意控制定势能够激活与其相应的语义概念, 使其吸引注意并调节空间注意分配; (4)知觉表征和语义概念的激活可能是双向的, 激活后在指导注意转移上表现出相同的特性。     

亚词汇水平加工的本质:形旁的语音激活

该研究利用启动命名技术,探讨了汉字加工时是否存在着形旁的语音激活。把含有独立成字的形旁的合体字（如“躲”）作为启动字,与形旁同音的字（如“深”）作为目标字。结果发现,当合体字是低频字时,目标字的命名速度显著加快。高频合体字则没有此效应。集合Ｚｈｏｕ和Ｍａｒｓｌｅｎ－Ｗｉｌｓｏｎ关于声旁语义激活的研究,该文得出结论说,汉字亚同汇水平的加工与词汇水平的加工表现一样,两者之间并无本质性的差别。     

纳西象形文字识别中的形、音、义激活

对纳西象形文字识别中的形、音、义激活进行了考察。实验1采用色词干扰的实验范式。结果表明,纳西象形文字的字形比字音和语义更易被激活。命名颜色字的形似字的颜色比命名颜色字的音同或音似字、语义联想字的颜色快。实验2采用色词干扰实验范式的变式。结果表明,当SOA=100ms时,颜色字及其形似字对颜色块命名的启动效应显著。当SOA为200ms和400ms时,颜色字的语义联想字对颜色块命名的启动效应显著。整个研究表明,在纳西象形文字识别中,字形信息首先被激活,其次是语义,字音的激活不明显。纳西象形文字的识别符合直通假设。所以如此,与纳西象形文字的特点有关     

不一致性重读对口语语篇加工中信息激活水平的影响

利用跨通道词汇再认任务,探索了口语临场加工过程中,不一致性重读对新信息以及它所标示的旧信息在语篇表征中激活的影响。结果表明：与控制条件相比,不一致性重读虽然提高了旧信息在语篇表征中的激活水平,但是同时抑制了新信息的激活;这一促进和抑制作用在关键词汇后的500 ms就已出现。从而说明,对于相对重要的新信息,不一致性重读会阻碍语篇的理解,并且会影响到语篇的临场加工过程。     

Differences in numeric,verbal, and spatial reasoning between engineering and literature students through a neurocognitive lens

This study used electroencephalography to investigate the brain activations of college students of various disciplines when they responded to questions in numeric, verbal, and spatial reasoning tasks. In total, 15 engineering students and 15 literature students were recruited in this experiment and were asked to respond to 12 intelligence test questions. The results were as follows: (i) the participants’ brain activations increased in the frontoparietal network during the numeric reasoning task, and the spectral power in the right anterior temporal cortex was generally higher in the literature students than in the engineering students. (ii) Activations of the language network were observed during the verbal reasoning task, and the spectral power in the right-biased posterior frontal cortex was generally higher in the literature students than in the engineering students; by contrast, the spectral power in the left lateral frontal cortex was generally higher in the engineering students than in the literature students. (iii) The participants’ brain activations increased in the spatial processing network during the spatial reasoning task, and the spectral power in the right posterior temporal cortex was generally higher in the literature students than in the engineering students.

言语产生中音韵编码的计划广度:来自图-词干扰范式的证据

采用图-词干扰范式,要求被试口语产生包含三个名词的句子,同时听觉呈现干扰刺激并操纵其与各个名词的语音相关性,通过与无关刺激相比,与各个名词语音相关的干扰刺激产生的语音效应,探讨句子产生中音韵编码的计划广度,同时检验音韵编码的层级激活假设。结果发现,只有第一个名词上出现了语音促进效应,第二和第三个名词上既无语音促进,也无语音干扰。该结果与层级激活假设相悖,表明句子产生中音韵编码的计划广度为第一个韵律词。     

The influence of maternal anxiety and depression symptoms on fNIRS brain responses to emotional faces in 5- and 7-month-old infants

Greater relative right (versus left) frontal cortical activation to emotional faces as measured with alpha power in the electroencephalogram (EEG), has been considered a promising neural marker of increased vulnerability to psychopathology and emotional disorders. We set out to explore multichannel fNIRS as a tool to investigate infants’ frontal asymmetry responses (hypothesizing greater right versus left frontal cortex activation) to emotional faces as influenced by maternal anxiety and depression symptoms during the postnatal period. We also explored activation differences in fronto-temporal regions associated with facial emotion processing. Ninety-one typically developing 5- and 7-month-old infants were shown photographs of women portraying happy, fearful and angry expressions. Hemodynamic brain responses were analyzed over two frontopolar and seven bilateral cortical regions subdivided into frontal, temporal and parietal areas, defined by age-appropriate MRI templates. Infants of mothers reporting higher negative affect had greater oxyhemoglobin (oxyHb) activation across all emotions over the left inferior frontal gyrus, a region implicated in emotional communication. Follow-up analyses indicated that associations were driven by maternal depression, but not anxiety symptoms. Overall, we found no support for greater right versus left frontal cortex activation in association with maternal negative affect. Findings point to the potential utility of fNIRS as a method for identifying altered neural substrates associated with exposure to maternal depression in infancy.     

新颖性寻求对创造性行为表现的影响：语义网络的中介作用

研究采用物品多用途任务、中文复合远距离联想任务和汉语双字词词对相关性判断任务,考察新颖性寻求特质水平对创造性表现的影响,探明语义网络在其中的作用。结果发现：高新颖性寻求个体在物品多用途任务中有更高的新颖性得分,而在中文复合远距离联想任务中与低新颖性寻求个体表现一致;在低相关词对判断时,高新颖性寻求个体反应时更短;低相关词对的判断反应时在新颖性寻求对创造性行为表现的影响中起部分中介作用。结果预示,新颖性寻求特质有利于个体建构形成能快速激活远距离信息的语义网络,进而促进创造性行为表现。     

How does the extraversion personality trait influence false recall with the Deese–Roediger–McDermott (DRM) paradigm?

Relative to more introverted persons, extraverts have been found to exhibit better recall and recognition in a range of memory paradigms including demonstrating a superior semantic priming effect. The present study sought to establish whether this aspect of personality might be associated with the false memory paradigm developed by Deese, Roediger, and McDermott (the DRM paradigm). Lists containing semantically related words were presented to extraverts, ambiverts, and introverts. Compared to the other two groups, extraverts falsely recalled more critical lures (words that although semantically related were not in the original lists) and non-list words. The results are discussed in relation to the concept of spreading activation.
