数字概念的视知觉无意识语义启动效应

研究了数字概念大小判断任务中的无意识语义启动效应。被试为天津师范大学本科生和研究生 5 6名。仪器为 pentiumIII高分辨率计算机 ,程序用E prime心理实验软件系统编制而成。在实验一中 ,用信号检测论技术发现 ,当启动数字呈现为 30ms时 ,被试是不能觉知到启动数字的 ;在实验二中 ,启动数字和靶数字使用相同的刺激序列 ,用MANOVA分析了启动数字和靶数字属于不同字体时的启动效应 ,发现启动数字对靶数字加工有促进或抑制作用 ;在实验三中 ,启动数字和靶数字使用两个不同的刺激序列 ,同样发现类似的启动效应。实验证据提示 ,无意识知觉能够达到语义水平上的加工     

重复线索化和靶子注意定向对返回抑制的影响

在返回抑制范式下 ,利用线索—靶子模式进行了两个实验 ,以大学生为被试 ,以重复线索化次数来操纵线索化阶段的注意 ,以靶子的注意定向来操纵靶子加工阶段的注意 ,探讨注意对返回抑制的影响。实验一采用连续线索化方式 ,发现当靶子为自主性注意定向时 ,线索化次数对返回抑制有显著影响 ,线索化 3次时返回抑制值大于线索化 1次和 2次 ;当靶子为反射性注意定向时 ,线索化次数对返回抑制无影响。实验二采用交叉线索化方式 ,发现线索化次数对返回抑制的影响正好与实验一相反。两个实验一致表明 ,无论是线索化阶段的注意 ,还是靶子加工阶段的注意 ,均对返回抑制有显著影响 ;并且 ,在对返回抑制的影响上 ,二者存在显著交互作用。从而支持注意影响返回抑制的观点。该结果对返回抑制的机制研究有一定意义。     

社会信息归类过程中刻板印象的内隐效应

采用信号检测论和间接测量方法探讨社会信息归类过程中的刻板印象内隐效应。实验结果表明 :⑴范畴启动可以自动激活有关的刻板印象内容 ,说明在很大程度上刻板印象是归类过程的一种必然结果与产物 ;⑵那些在内容上与范畴启动所导致自动的刻板印象激活及其相关内容一致、不一致或相反的建构分别易于出现同化与对比效应 ;⑶在个体水平上 ,通过意识性抑制在短期内很难压制刻板印象的自动激活 ,这表明刻板印象加工在很大程度上涉及到内隐过程     

笔画复杂性和重复性对笔画和汉字认知的影响

采用笔画识别和词汇决定的方法 ,对汉字笔画认知和笔画在汉字认知中的作用作了考察。实验一探讨了汉字笔画自身的复杂性对笔画认知的影响。结果表明 ,笔画自身的复杂性对笔画认知无显著影响 ,识别简单笔画和识别复杂笔画的反应时与错误率无显著差异。实验二考察了笔画的重复性对汉字认知的影响。结果表明 ,汉字认知中存在笔画重复性效应。笔画重复较多的汉字比笔画较少重复的汉字识别时间短 ,错误率亦低。整个实验结果支持笔画是汉字加工的基本单元的假设     

不同情绪模式的图片刺激启动效应

探讨了不同情绪模式的图片启动效应。选取大学生被试240名,将其分成4组,一个实验组和一个控制组,实验组组分别施加愉快、悲伤和恐惧情绪刺激,控制组施加中性刺激,然后检测4个组的情绪变化情况。结果发现,通过图片产生的情绪启动效应是明显的,实验组的情绪强度都超过控制组,尤其是愉快情绪和悲伤情绪,与控制组差异显著。研究还发现了情绪启动效果随时间而发生变化的趋势,消极情绪（悲伤情绪和恐惧情绪）随着时间的推移,强度锐减,在3分钟内基本恢复正常;但是,在短时间内（5分钟）,积极情绪（愉快情绪）随着时间的推移而产生了增长的趋势,这种趋势可能是由于人的心理促进作用造成的     

Bicultural mind, self-construal, and self- and mother-reference effects: Consequences of cultural priming on recognition memory

Two experiments showed that American (vs. Chinese) culture priming influences Beijing Chinese undergraduates’ self-construal and its attendant memory strategies. Following American culture priming (vs. Chinese culture priming or control), the participants used relatively more independent self-statements and fewer interdependent self-statements to describe the self (Experiment 1). They also performed more poorly in a delayed recognition test if they had encoded the study materials (personality adjectives) with reference to the mother (Experiment 2). These results demonstrate the activation effect of culture on self-construal and its attendant memory processes. The results also show that biculturals can access different cultural conceptions of the self and change cognitive strategies flexibly in response to cues of changing cultural demands in the immediate context.     

Positive and negative associations underlying ambivalent attitudes

In two studies, we compared the strength of positive and negative associations of ambivalent attitudes to those of nonambivalent attitudes. In Study 1, results from an implicit association task showed that, in contrast to nonambivalent attitudes, ambivalent attitudes were characterized by strong positive and negative associations. In Study 2 responses to ambivalent attitude objects were faster following a positive as well as following a negative prime, compared to a non-word prime, whereas for neutral attitude objects prime type did not influence response times. Results provide direct evidence for the assumption that both positive and negative associations of ambivalent attitudes are relatively strong. Implications for attitude strength and attitude structure are discussed.     

泛文化的自尊——基于中国大学生的研究证据

过去一直认为,自尊是人类普遍的需要,是泛文化的。但是,过去十多年来,这一观点受到严重挑战。其主要理由是许多跨文化的研究显示集体主义文化下个体的自尊显著低于西方,少有自我促进的迹象。但是,几乎所有这样的证据都是来自自陈式测量。由于自陈式测量难以避免自我展现（Self-presentation）或社会期许（Social Desirability）的影响,并且严重依赖于个体的自我报告,本研究采用新的能够防止社会期许的影响并能触及无意识的内隐测量——阈下评价性启动（Subliminal Evaluative Priming）程序,对中国大学生的自尊进行了研究。结果发现中国大学生对自我持有显著的积极、肯定的评价,中国人存在内隐自尊。这表明,集体主义文化下的个体的自尊需要是存在的,只是以内隐的方式表现或在自我展现的影响最小化后表现出来。这一发现和自尊的泛文化论是一致的     

Conceptual priming with pictures and environmental sounds

A series of experiments was conducted to examine conceptual priming within and across modalities with pictures and environmental sounds. In Experiment 1, we developed a new multimodal stimulus set consisting of two picture and sound exemplars that represented 80 object items. In Experiments 2, we investigated whether categorization of the stimulus items would be facilitated by picture and environmental sound primes that were derived from different exemplars of the target items; and in Experiments 3 and 4, we tested the additional influence on priming when trials were consolidated within a target modality and the inter stimulus interval was lengthened. The results demonstrated that target categorization was facilitated by the advanced presentation of conceptually related exemplars, but there were differences in effectiveness when pictures and sounds appeared as primes.     

Social priming of dyslexia and reduction of the Stroop effect: What component of the Stroop effect is actually reduced?

Recently, Goldfarb, Aisenberg, and Henik (2011) showed that in a manual format of the Stroop task, dyslexia priming eliminates the normal magnitude of the interference-based Stroop-like findings otherwise exhibited by individuals participating in such research. Goldfarb et al. (2011) consequently concluded that the effect of word reading in a Stroop task (i.e., one automatic behavior) can be effectively controlled through an automatic instruction “do not read” (i.e., another automatic behavior). The present study further investigated these ideas by examining when and how dyslexia priming controls different processes involved in a Stroop task. To this end, the original finding was first replicated (Experiment 1) and subsequently extended to the vocal (instead of manual) response modality to examine whether previously reported eliminations of the Stroop effect persist with this response format (i.e., format producing larger Stroop effects). Since past work (e.g., Augustinova & Ferrand, 2012a; Brown, Joneleit et al., 2002; Ferrand & Augustinova, 2013) had suggested that various interventions were likely to reduce (rather than eliminate) the interference-based Stroop-like findings with vocal responses, a further aim of these experiments was to identify the component of these findings that dyslexia priming actually reduces. To this end, the effects of this intervention were examined in a more fine-grained variant of the Stroop task that distinguished between interference resulting from task-irrelevant processes involved in computing the lexical and semantic representations of the word (i.e., a written distractor to ignore) and task-relevant processes involved in the selection of a response (i.e., a color target to name) that are both involved in this task. In line with our past work (e.g., Augustinova & Ferrand, 2012a; Ferrand & Augustinova, 2013), the results of two experiments (Experiments 2 and 3) showed that in the vocal format, dyslexia priming reduces but does not eliminate the normal magnitude of the interference-based Stroop-like findings and that this reduction is solely due to the control of processes involved in the selection of a response (i.e., a color target to name) – processes that are known to be controllable in this format (Ferrand & Augustinova, 2013). Given that in this format, dyslexia priming had no effect on task-irrelevant processes involved in computing the lexical and semantic representations of a written distractor to be ignored – processes that are known to be automatic – further implications for the control of automatic processes via dyslexia priming are considered and an interpretation in terms of a unitary control mechanism for both the manual and vocal formats is proposed.
