Carver and Whites’ BIS/FFFS/BAS scales and domains and facets of the Five Factor Model of personality

Few empirical studies have investigated the relationship between Gray’s Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) of personality. In a large sample of undergraduates (N = 779), we examined the relationship between FFM domains and facets and the revised RST (see Gray & McNaughton, 2000). Regression and partial correlation analyses indicated that only FFM Agreeableness discriminates between the BIS and FFFS. Other differences at the facet level were found for Neuroticism facets of Self-Consciousness and Angry Hostility (negatively), Agreeableness facets of Compliance and Modesty, and Conscientiousness facets of Self-Discipline and Deliberation. These findings emphasize social inhibition and constraint in the BIS, compared to the FFFS.

语音的自动激活及其在汉字语义通达中的作用

采用Stroop实验范式及其变式研究了语音的自动激活及其在汉字语义通达中的作用。在实验一中,要求被试大声读出汉字的颜色,除了获得经典的Stroop促进效应之外,结果还发现：当汉字颜色对应的读音与汉字读音一致(如红色的“洪”字)时,被试的反应会显著加快。在实验二中,要求被试判断汉字的颜色并按下相应的键,得到了与实验一相似的结果模式。这些结果表明,语音在汉字的识别过程中是自动激活的,并且有助于语义通达。     

The deautomatization of accessible attitudes

The attitudinal effects of repeatedly encountering an object in a setting where an attitude was unneeded were investigated. In three experiments, participants repeatedly recognized words with strong evaluative connotations. A priming task was subsequently performed in which the repeatedly recognized words or control words served as primes. As expected, the attitudinal priming effects of the attitudes toward the repeated words were attenuated relative to the control words. This reduction in automatic attitude activation was observed even a day after the repeated recognition task, suggesting that attitudinal deautomatization is a relatively enduring effect that is not limited to the immediate context. The likelihood of automatic attitude activation was not diminished by the repeated evaluation of an object, indicating that the effect was not due to semantic satiation or fatigue of the attitude-object connection. A number of additional potential mediators of the deautomatization of attitudes were ruled out by the results. The findings highlight the functional nature of attitudes. Attitudes facilitate the appraisal of objects and the making of decisions. However, when the need to evaluate an object in a context decreases, the automatic activation of attitudes diminishes.     

The Effect of the Balance of Orthographic Neighborhood Distribution in Visual Word Recognition

The present study investigated whether the balance of neighborhood distribution (i.e., the way orthographic neighbors are spread across letter positions) influences visual word recognition. Three word conditions were compared. Word neighbors were either concentrated on one letter position (e.g.,nasse/basse-lasse-tasse-masse) or were unequally spread across two letter positions (e.g.,pelle/celle-selle-telle-perle), or were equally spread across two letter positions (e.g.,litre/titre-vitre-libre-livre). Predictions based on the interactive activation model [McClelland & Rumelhart (1981). Psychological Review, 88, 375–401] were generated by running simulations and were confirmed in the lexical decision task. Data showed that words were more rapidly identified when they had spread neighbors rather than concentrated neighbors. Furthermore, within the set of spread neighbors, words were more rapidly recognized when they had equally rather than unequally spread neighbors. The findings are explained in terms of activation and inhibition processes in the interactive activation framework.     

The Effect of Phonological Structure on Visual Word Access in Bilinguals

Two experiments examined if visual word access varies cross-linguistically by studying Spanish/English adult bilinguals, priming two syllable CVCV words both within (Experiment 1) and across (Experiment 2) syllable boundaries in the two languages. Spanish readers accessed more first syllables based on within syllable primes compared to English readers. In contrast, syllable-based primes helped English readers recognize more words than in Spanish, suggesting that experienced English readers activate a larger unit in the initial stages of word recognition. Primes spanning the syllable boundary affected readers of both languages in similar ways. In this priming context, primes that did not span the syllable boundary helped Spanish readers recognize more syllables, while English readers identified more words, further confirming the importance of the syllable in Spanish and suggesting a larger unit in English. Overall, the experiments provide evidence that readers use different units in accessing words in the two languages.     

The influence of second language proficiency on bilingual parallel language activation in Hindi–English bilinguals

We investigated the spontaneous activation of phonologically related words in high and low proficient Hindi–English bilinguals during spoken word processing in an eye-tracking study. Participants listened to spoken words in L1/L2 and looked at a display (consisting of line drawings of phonological cohort of the translation equivalent of the spoken word and unrelated distractors). Both the groups were quick in orienting their attention towards the competitor with the onset of the spoken word. Furthermore, high proficient bilinguals showed higher and earlier activation of the competitor compared to low proficient bilinguals. Cross-language activations were higher in the L2–L1 direction for both the groups. The results strongly suggest language non-selective access of translation in Hindi–English bilinguals in both language directions. We discuss the results with regard to the predictions of the bilingual language processing models and the effect of language proficiency on conceptual access during listening in bilinguals.     

Precis of <Emphasis Type="Italic">Philosophy and Neuroscience</Emphasis>: <Emphasis Type="Italic">A Ruthlessly Reductive Account</Emphasis>

This book precis describes the motives behind my recent attempt to bring to bear “ruthlessly reductive” results from cellular and molecular neuroscience onto issues in the philosophy of mind. Since readers of this journal will probably be most interested in results addressing features of conscious experience, I highlight these most prominently. My main challenge is that philosophers (even scientifically-inspired ones) are missing the nature and scope of reductionism in contemporary neuroscience by focusing exclusively on higher-level cognitive neuroscience, and ignoring the discipline's cell-physiological and molecular-biological core.     

语音与词义激活的相对时间进程:来自儿童发展的证据

本研究从儿童语言发展的角度．在已有研究基础上．进一步考察了汉语视觉字词加工中语音与词义激活的相对时间进程。运用启动命名技术,比较了三年级和六年级儿童在语音和语义启动中的表现。结果发现,三年级和六年级儿童都有语音和语义启动效应,且六年级儿童更为显著。但语义启动和同音启动的促进效应之间没有差异,而同音不同声调启动则可能产生抑制作用。文章探讨了这些发现对汉语视觉字词加工中词义信息提取不同观点的含义。     

Psychological defense mechanisms and electroencephalographic arousal

The aim of this study was to examine the relationship between psychological defense as measured by the Kragh tachistoscopic Defense Mechanisms Test (DMT), and general arousal properties of the individual as measured with electroencephalogram (EEG). The DMT assesses defense by presenting neutral and threatening pictures with very short exposure times. EEG characteristics were measured in the 8–12 Hz EEG frequency band during DMT testing. Twenty-one male subjects participated in the study. All were US Air Force personnel on active duty. Personnel with high defense mechanisms, defined in this connection as slow perception of the threat, tended to have higher cortical arousal after Stimulus exposure than the subjects with low defense mechanisms. The differences occurred mainly with new stimulus material without any threatening content. The differences in arousal response to novel stimuli may contribute to an understanding of the relationships between the Kragh DMT test and performance in life-threatening situations.
