局部亮度与语义关系对真实情景识别的影响

以真实情景图片为材料,探讨局部亮度与语义关系对情景识别的影响,以及情景背景线索和语义关系的获得。实验一结果显示,被试对有无语义关系情景图片的识别反应时存在显著差异,且对拼接图片的识别正确率更高,反应时更短。实验二探讨了局部亮度与呈现时间变化条件下情景背景线索和语义关系的获得。结果发现,情景语义关系和背景信息的获得受到局部亮度变化和呈现时间的影响。这表明,语义关系和呈现时间对情景识别存在显著影响,而且这种影响与情景背景线索和语义关系的获得有关。呈现时间越长,越易获得情景语义关系。局部亮度变化越小,背景线索越易获得,呈现时间的影响越小。     

阈上和阈下不同情绪线索对返回抑制的影响

为检验返回抑制是否受线索生物学意义的调节, 分别在实验一和实验二中以阈上和阈下不同情绪效价(高兴、生气和中性)的面孔为外源性线索, 变化同时提示位置的多寡, 要求被试对靶子尽可能快而准地作探测反应。实验一发现, 三种线索情况下均出现返回抑制且效应量无显著差异; 实验二发现, 线索为中性面孔时出现返回抑制, 线索为高兴和生气面孔时未出现返回抑制。说明返回抑制受线索生物学意义的调节。阈下线索的生物学意义(情绪效价)能得到自动加工, 从而影响空间注意的转移和返回抑制机制的功用; 阈上线索的情绪效价被清晰感知时, 自上而下的注意控制机制使线索的生物学意义被忽略, 从而阻碍情绪效价功能的发挥。     

反应选项对时序知觉重复启动效应的影响

先前研究采用两项反应任务发现了时序知觉重复启动效应, 这可能是反应选项导致的虚假效应, 本研究采用三项反应任务对此进行了检验。实验1运用三项判断任务以消除缺乏中间选项所致的反应偏向, 结果发现重复启动显著影响“哪个图形先出现”和“两个图形同时出现”的时序判断; 实验2在实验1的基础上对“同时出现”反应选项进行两种指导语操作, 实验结果不仅与实验1一致, 而且“有把握时判断为同时出现”和“有无把握都判断为同时出现”之间没有显著差异, 说明被试能够识别时序加以判断, 不支持反应偏向的前提条件。因此, 时序知觉重复启动效应不是反应选项产生的反应偏向引发的虚假效应, 重复启动对“系列性”和“同时性”时序知觉都存在显著影响。     

情色文字与图片对大学生性倾向印象形成的启动差异

128名大学生被平均分成四个组,分别接受情色文字刺激、非情色文字刺激、情色图片刺激与非情色图片刺激,考察不同材料的情色信息会对性倾向印象形成产生怎样的启动效应。结果表明:情色文字对性倾向印象形成产生显著的正向启动效应,而情色图片对性倾向印象形成的启动没有呈现出单一方向的显著效应;男性对他人的性倾向印象形成要显著高于女性,但性别因素不对启动效应产生中介影响;接触容易令人产生性联想的情色刺激会导致个体更倾向于以性的或情色的眼光看待他人。     

Looks aren’t Everything: Pseudohomophones Prime Words but Nonwords do not

After examining literature that deals with phonological and orthographic effects associated with pseudohomophones, the current effort deviates from the norm by using fewer pseudohomophones (20) and extending the lags between primes and targets (M=8). Word and pseudohomophone primes were found to facilitate lexical decision response latencies to word targets. Response latencies to word targets were not influenced by nonword primes, however. The presence of pseudohomophone effects was demonstrated by longer response latencies and higher error rates for pseudohomophones (e.g., DREEM) that were equated in orthography to nonword controls (e.g., DROAM). Despite the frequency effect observed for base words, the pseudohomophones did not exhibit an effect of base word frequency. The results suggest that phonological codes exert an influence on lexical representation but are not frequency sensitive.     

LOGICAL PLURALISM AND SEMANTIC INFORMATION

Up to now theories of semantic information have implicitly relied on logical monism, or the view that there is one true logic. The latter position has been explicitly challenged by logical pluralists. Adopting an unbiased attitude in the philosophy of information, we take a suggestion from Beall and Restall at heart and exploit logical pluralism to recognise another kind of pluralism. The latter is called informational pluralism, a thesis whose implications for a theory of semantic information we explore.

Reading spoken words: orthographic effects in auditory priming

Three experiments examined the involvement of orthography in spoken word processing using a task - unimodal auditory priming with offset overlap - taken to reflect activation of prelexical representations. Two types of prime-target relationship were compared; both involved phonological overlap, but only one had a strong orthographic overlap (e.g., dream-gleam vs. scheme-gleam). In Experiment 1, which used lexical decision, phonological overlap facilitated target responses in comparison with an unrelated condition (e.g., stove-gleam). More importantly, facilitation was modulated by degree of orthographic overlap. Experiment 2 employed the same design as Experiment 1, but with a modified procedure aimed at eliciting swifter responses. Again, the phonological priming effect was sensitive to the degree of orthographic overlap between prime and target. Finally, to test whether this orthographic boost was caused by congruency between response type and valence of the prime-target overlap, Experiment 3 used a pseudoword detection task, in which participants responded "yes" to novel words and "no" to known words. Once again phonological priming was observed, with a significant boost in the orthographic overlap condition. These results indicate a surprising level of orthographic involvement in speech perception, and provide clear evidence for mandatory orthographic activation during spoken word recognition.     

On the predictive validity of indirect attitude measures: Prediction of consumer choice behavior on the basis of affective priming in the picture-picture naming task

Recent studies have revealed that robust and replicable affective priming of naming responses can be obtained when pictures are used as primes and targets. The aim of the present research was to examine the predictive validity of affective priming effects that are obtained with the picture-picture naming task. In two studies that were modeled after [Karpinski, A., & Hilton, J. L. (2001). Attitudes and the Implicit Association Test. Journal of Personality and Social Psychology, 81, 774-778], we observed that individual difference scores that are obtained with the naming task exhibit good predictive validity. Both practical and theoretical implications of this finding are discussed.     

Nonconscious relationship reactance: When significant others prime opposing goals

Individuals nonconsciously and unintentionally pursue goals they associate with relationship partners ( [Fitzsimons and Bargh, 2003] and [Shah, 2003]). Here, we demonstrate conditions under which individuals nonconsciously and unintentionally reject goals they associate with relationship partners and instead pursue opposing goals. In Experiment 1, participants were subliminally primed with the name of a controlling significant other who had a particular goal for them. Without awareness or intent, participants pursued a goal that directly opposed their significant other’s wishes. In Experiment 2, chronic reactance was shown to moderate this effect: Low-reactant individuals adopted a subliminally primed significant other’s goal, whereas high-reactant individuals pursued an opposing goal. This research suggests that in response to controlling significant others and among chronically reactant individuals, the nonconscious activation of relational representations can automatically elicit oppositional goal pursuits, even when pursuit of an oppositional goal results in a personally suboptimal outcome.     

The categorical structure of knowledge for famous people (and a novel application of Centre-Surround theory)

Knowledge of familiar people is essential to guide social interaction, yet there is uncertainty about whether semantic knowledge for people is stored in a categorical structure as for objects. Four priming experiments using hard-to-perceive primes investigated whether occupation forms a category connecting famous persons in semantic memory. Primes were famous faces exposed for 17ms with masking, resulting in severely restricted awareness and thus precluding expectancy-based priming effects. Targets were consciously perceptible famous faces (Experiments 1-3), famous names (Experiment 3), or occupations (Experiment 4) representing either the same or different occupation to the prime. Significant priming demonstrated the operation of automatic processes, including spreading activation, among persons sharing a common occupation; this supports the categorical view. The direction of priming (faster/slower responses to same-occupation than different-occupation targets) was dependent on prime-target stimulus onset asynchrony (Experiments 1-3) and type of target (Experiment 4). This pattern of results is attributed to the Centre-Surround mechanism proposed by Carr and Dagenbach [Carr, T. H., & Dagenbach, D. (1990). Semantic priming and repetition priming from masked words: evidence for a centre-surround attentional mechanism in perceptual recognition. Journal of Experimental Psychology: Learning, Memory and Cognition, 16, 341-350]. These results support (a) the categorical structure of semantic knowledge for famous people and (b) the application of the Centre-Surround mechanism to the domain of person recognition.
