Deflecting negative self-relevant stereotype activation: The effects of individuation

Under stereotype threat, when an individual risks confirming a negative self-relevant stereotype, activation of the stereotype can inhibit performance on a subsequent, related task. Although a significant amount of research has been devoted to examining the effects of stereotype activation on performance, relatively little is known about successful methods of intervention. Two experiments tested the hypothesis that individuation prior to performance would eliminate impairment due to stereotype activation. In both studies, Caucasian female participants in either a gender-prime or no-prime condition were administered a mathematics test. Gender primed, individuated participants outperformed gender primed, non-individuated participants and performed as well as unprimed, non-individuated (i.e., control) participants, supporting individuation as a protective measure against the detrimental effects of negative stereotype activation.     

正、负性情绪的跨文化心理测量:PANAS维度结构检验

对中国大学生(N=201)和美国大学生(N=321)进行PANAS测评,以检验该量表中、英文版的因素效度。探索性因素分析会聚性地验证了该量表的PA和NA两维度结构具有跨文化一致性,中、英文量表两因子的累积方差贡献率分别为51.31％和44．25％,接近Watson等的研究结果。然而研究结果也显示测项偏差问题,因此中文量表的PA分量表的测项组成不等同于原量表。中、英文量表的PA与NA分量表同样具有较高内在一致性信度,表明其符合心理测量学要求。     

语音意识、快速命名与中文阅读

本研究考察了语音意识、快速命名与中文阅读的关系．一系列回归分析发现．语音意识对中文读字、中文默字和快速阅读理解的解释量大于快速命名。快速命名先进入方程时对一分钟读字有更大的解释量。控制发音速度对一分钟读字的影响后,快速命名和语音意识对一分钟读字的解释量减小。这些结果说明．与语音意识相比,快速命名对中文阅读有独立的、微弱的影响。文章讨论了语音意识和快速命名与中文阅读的关系,并根据实验结果分析了快速命名的认知结构。     

Semantic and phonological influences on visual word learning in a transparent language

Orthographic representations of words are indispensable for reading fluency. The ways in which these representations are developed and their resistance to decay are hotly debated topics. The aim of this study was to investigate the influence of semantic and phonological representations on the formation of orthographic representations in a transparent orthography. In order to achieve this objective, an experiment with three conditions was carried out. In the first condition, a group of university students were asked to repeatedly read 10 new words after semantic and phonological training, in the second condition another group of participants read the new words after phonological training, and in the third condition participants read without previous training. Finally, a follow-up session was performed to test the resistance to decay of the orthographic representations. The results showed that participants who had received semantic training formed the representations faster than participants in the other conditions, as indicated by the decrease in length effect. These results indicate the important role of previous knowledge when people face new written words. A month later these orthographic representations still remained in the lexicon of the participants.     

Cross-linguistic phonotactic competition and cognitive control in bilinguals

The current study examines the relation between cognitive control and linguistic competition resolution at the sublexical level in bilinguals. Twenty-one Spanish–English bilinguals and 23 English monolinguals completed a non-linguistic Stroop task (indexing inhibitory control) and a linguistic priming/lexical decision task (indexing Spanish phonotactic-constraint competition during English comprehension). More efficient Stroop performance (i.e. a smaller Stroop effect) in bilinguals was associated with decreased competition from Spanish phonotactic constraints during English comprehension. This relation was observed when nonword targets overlapped in phonotactic constraints and phonological form with preceding cognate primes (e.g. prime: stable (Spanish: estable)/target: esteriors). Findings suggest a link between non-linguistic cognitive control and co-activation of linguistic structures at the sublexical level in bilinguals.     

汉语言语产生中语音、字形启动的位置效应

以起始掩蔽启动效应(the Masked Onset Priming Effect, 简称MOP效应)为研究背景, 通过3个实验, 考察了语音和字形在MOP效应产生中的作用, 以及在汉语单字词产生中语音、字形启动的位置效应。实验1表明, 在汉语单字词的产生中, 语音启动的位置效应显著, 声母启动的效应量显著大于韵母启动的效应量, 与拼音文字研究得到的MOP效应类似, 说明在MOP效应中至少包含有语音效应。汉字单字词语音编码的最小单位是音位, 而且具有从左到右序列加工的特点, 支持言语产生的“音节临时形成论”。实验2表明, 与目标字左、右部件相同的启动刺激均能促进掩蔽启动范式中的命名反应, 被试对与启动字的右部件相同的目标字的反应显著快于对与启动字的左部件相同的目标字的反应, 与起始掩蔽启动效应的假设相反, 说明在MOP效应中不包含有字形的作用, 却发现了汉字单字词特有的命名的字形位置效应：右部件启动的效应量大于左部件启动的效应量。实验3采用图-词干扰范式对汉字左、右部件的启动效应做了进一步的探讨, 仍然发现汉字右部件启动的效应量显著大于汉字左部件启动的效应量。整个研究表明, MOP效应是单纯的语音效应, 并不包含有字形的作用; MOP效应产生于言语产生中的语音编码阶段, 支持言语计划理论的观点。     

语音在汉字语义通达中作用的研究述评

语音在汉字语义通达中的作用是二十多年来心理语言学研究的热点之一。直通假设和形音交互假设是学者们主张的理论观点,它们在语音和语义的相互关系上存在分歧,并分别有各自的实验证据。从比较语音语义激活时间进程、同音字效应、神经心理学与脑成像、语音作用的发展转换这四个方面对过去的研究进行回顾,指出了实验范式和实验材料中存在的问题,并提出结合汉字特点进行研究的思路。     

汉语双字词超音段信息在语义激活中的作用

采用眼动方法,通过两个实验考察了汉语双字词超音段信息在语义激活中的作用。结果显示：（1）汉语双字词语义激活过程中,分别改变首字声调和尾字声调对语义激活起到抑制作用,首字声调改变时的抑制作用更大。结果支持了Cohort模型。（2）语义相关词的注视点和注视时间远远多于其控制词,但没有发现词频效应。（3）汉语声调的加工过程与声韵母一样,独立作用于语义激活过程。     

Gender Stereotype Activation versus Lexical Semantic Activation: An ERP Study

It is an open question whether social stereotype activation can be distinguished from nonsocial semantic activation. To address this question, gender stereotype activation (GSA) and lexical semantic activation (LSA) were directly compared. EEGs were recorded in 20 participants as they identified the congruence between prime-target word pairs under four different conditions (stereotype congruent, stereotype incongruent, semantic congruent, and semantic incongruent). We found that congruent targets elicited faster and more accurate responses and reduced N400 amplitudes irrespective of priming category types. The N400 congruency effect (i.e., the difference between incongruity and congruity) started earlier and had greater amplitude for GSA than for LSA. Moreover, gender category priming induced a smaller N400 and a larger P600 than lexical category priming. These findings suggest that the brain is not only sensitive to both stereotype and semantic violation in the post-perceptual processing stage but can also differentiate these two information processes. Further, the findings suggest superior processing (i.e., faster and deeper processing) when the words are associated with social category and convey stereotype knowledge.
