数字概念的视知觉无意识语义启动效应 总被引:2,自引:0,他引:2
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 相似文献

东西方面孔异族效应机理的电生理学证据 总被引:5,自引:1,他引:4
采取事件相关电位方法研究东西方面孔记忆编码的差异(DM效应),从而阐明异族效应的神经机制。14名被试学习和再认东西方面孔照片的实验结果表明,无论记住与否,西方面孔产生的早期成分(潜伏期70~220ms)在头皮额部有一个比东方面孔更为正向的变化,表明在此阶段更多的资源分配于异族面孔,支持异族效应产生的特征选择假说。无论东方面孔还是西方面孔,记住与未记住相比较,则在额部和顶部产生潜伏期在晚期正成分(LPC)范围的正走向变化,但西方面孔在240~320ms潜伏期范围内,DM效应较小。另外,东方面孔在枕部诱发出一个明显的负波N260,而西方面孔产生的N260很小甚至没有,反映了大脑对不同种族面孔的编码机制有所不同,因而可能被称为“种族特异波” 相似文献

Neuropsychologists are increasingly asked to make judgments regarding treatment options and rehabilitation strategies in addition
to evaluating the degree and scope of neuropsychological impairment following acquired brain injuries. The capacity to make
informed clinical decisions relies upon research investigating the relationships between neuropsychological and psychosocial
status (i.e., ecological validity). Unfortunately, much of this research employs exploratory analyses, an approach that can
lead to theoretical ambiguity and ad-hoc interpretations. The current availability and accessibility of analytical tools,
like structural equation modeling (SEM), however, permits the testing of specific hypotheses regarding ecological validity
and promotes a-priori theory development. In the current study, a theory-driven model of the ecological validity of a neurocognitive
assessment was tested against data obtained from individuals with acquired brain injury using SEM. The results provide confirmatory
evidence for the ecological validity of neurocognitive constructs and empirical support for a theory-driven analytical approach
to ecological validity research. 相似文献

The purpose of the present study was to examine the time course of race and expression processing to determine how these cues influence early perceptual as well as explicit categorization judgments. Despite their importance in social perception, little research has examined how social category information and emotional expression are processed over time. Moreover, although models of face processing suggest that the two cues should be processed independently, this has rarely been directly examined. Event-related brain potentials were recorded as participants made race and emotion categorization judgments of Black and White men posing either happy, angry, or neutral expressions. Our findings support that processing of race and emotion cues occur independently and in parallel, relatively early in processing. 相似文献

The majority of studies have demonstrated a right hemisphere (RH) advantage for the perception of emotions. Other studies have found that the involvement of each hemisphere is valence specific, with the RH better at perceiving negative emotions and the LH better at perceiving positive emotions [Reuter-Lorenz, P., & Davidson, R.J. (1981) Differential contributions of the 2 cerebral hemispheres to the perception of happy and sad faces. Neuropsychologia, 19, 609-613]. To account for valence laterality effects in emotion perception we propose an 'expectancy' hypothesis which suggests that valence effects are obtained when the top-down expectancy to perceive an emotion outweighs the strength of bottom-up perceptual information enabling the discrimination of an emotion. A dichotic listening task was used to examine alternative explanations of valence effects in emotion perception. Emotional sentences (spoken in a happy or sad tone of voice), and morphed-happy and morphed-sad sentences (which blended a neutral version of the sentence with the pitch of the emotion sentence) were paired with neutral versions of each sentence and presented dichotically. A control condition was also used, consisting of two identical neutral sentences presented dichotically, with one channel arriving before the other by 7 ms. In support of the RH hypothesis there was a left ear advantage for the perception of sad and happy emotional sentences. However, morphed sentences showed no ear advantage, suggesting that the RH is specialised for the perception of genuine emotions and that a laterality effect may be a useful tool for the detection of fake emotion. Finally, for the control condition we obtained an interaction between the expected emotion and the effect of ear lead. Participants tended to select the ear that received the sentence first, when they expected a 'sad' sentence, but not when they expected a 'happy' sentence. The results are discussed in relation to the different theoretical explanations of valence laterality effects in emotion perception. 相似文献

Event-related brain potentials were measured in 7- and 12-month-old infants to examine the development of processing happy and angry facial expressions. In 7-month-olds a larger negativity to happy faces was observed at frontal, central, temporal and parietal sites (Experiment 1), whereas 12-month-olds showed a larger negativity to angry faces at occipital sites (Experiment 2). These data suggest that processing of these facial expressions undergoes development between 7 and 12 months: while 7-month-olds exhibit heightened sensitivity to happy faces, 12-month-olds resemble adults in their heightened sensitivity to angry faces. In Experiment 3 infants' visual preference was assessed behaviorally, revealing that the differences in ERPs observed at 7 and 12 months do not simply reflect differences in visual preference. 相似文献
