How representationalism can account for the phenomenal significance of illumination

In this paper, I defend a representationalist account of the phenomenal character of color experiences. Representationalism, the thesis that phenomenal character supervenes on a certain kind of representational content, so-called phenomenal content, has been developed primarily in two different ways, as Russellian and Fregean representationalism. While the proponents of Russellian and Fregean representationalism differ with respect to what they take the contents of color experiences to be, they typically agree that colors are exhaustively characterized by the three dimensions of the color solid: hue, saturation, and lightness. I argue that a viable version of representationalism needs to renounce this restriction to three dimensions and consider illumination to be a genuine phenomenal dimension of color. My argument for this thesis falls into two parts. I first consider the phenomenon of color constancy in order to show that neither Russellian nor Fregean representationalism can do justice to the phenomenal significance of local illumination. I subsequently formulate a version of representationalism that accounts for illumination by taking it as a phenomenal dimension of color.     

句子语境中汉语词汇歧义消解的ERP研究

采用ERP方法,考察了汉语词汇歧义消解中句子语境作用的时间进程及大脑活动。目标词与句子语境存在一致、不一致、无关控制等3种关系。结果显示:(1)一致与不一致条件下N400的平均波幅均显著低于无关控制条件;(2)SOA为200毫秒时产生的N400平均波幅的幅度显著高于SOA为1000毫秒的条件;(3)N400的平均波幅及潜伏期均表现出左半球显著高于右半球的特点。实验结果支持词汇歧义消解的模块化观点,体现了大脑两半球语言功能的不对称性。     

Self‐ambivalence and reactions to success versus failure

People differ in the extent to which their self‐evaluations fluctuate in response to positive and negative events. This research tests whether self‐ambivalence predicts this self‐evaluative reactivity. Participants first completed measures of self‐ambivalence and baseline self‐esteem. Next, they were induced a success or failure experience in a cognitive task and finally rated their cognitive self‐evaluations (task‐specific ability, state self‐esteem) and affective reactions (self‐feelings, mood). Self‐ambivalence was associated with stronger effects of the success/failure manipulation on cognitive self‐evaluations but not on affective reactions, with baseline self‐esteem controlled. Possible underlying mechanisms are discussed. Copyright © 2006 John Wiley & Sons, Ltd.     

Being Admired or Being Liked: Classroom Social Status and Depressive Problems in Early Adolescent Girls and Boys

This study investigates associations between depressive problems and classroom social status in a large population cohort of Dutch early adolescents (N = 1046, age 13.52 +/- 0.51, 52.4% girls). Depressive problems were assessed by parent and self-reports and classroom status by peer nominations. We assessed peer status with respect to both achievement-related (being a good learner, being good at sports, being good-looking) and affection-related (being liked, being disliked, being best friend) areas. In boys, depressive problems were most strongly associated with not being good at sports, while in girls the association was strongest for not being liked. The risk of a low status in one area could largely be compensated by a high status in another area.

M(u)ler-Lyer错觉作用机制的眼动研究

使用美国应用科学实验室生产的504型眼动仪,以错觉量和眼动特征为指标,考察了Muller-Lyer(ML)错觉的产生及其作用过程.结果表明:(1)在ML错觉中,较长箭杆促进长度的准确判断,较长箭翼干扰长度的准确判断.减弱ML图形的总长度线索有助于降低错觉量;(3)箭杆与箭翼的交互作用对注视时间产生显著影响;(3)被试通过整合两条矛盾的线索进行长度判断,实验结果支持矛盾线索理论.     

The influence of height and key on the perceptual similarity of transposed melodies

In two experiments, the perceptual similarity between a strong tonal melody and various transpositions was investigated using a paradigm in which listeners compared the perceptual similarity of a melody and its transposition with that of the same melody and another transposition. The paradigm has the advantage that it provides a direct judgment regarding the similarity of transposed melodies. The experimental results indicate that the perceptual similarity of a strong tonal melody and its transposition is mainly determined by two factors: (1) the distance on the height dimension between the original melody and its transposition (pitch distance), and (2) the distance between keys as inferred from the circle of fifths (key distance). The major part of the variance is explained by the factor pitch distance, whereas key distance explains only a small part.     

视动刺激生理心理反应的实验研究

３０名男性军校学员。在两种指导语指导下,经受了一系列视动跃跃刺激（５、１０、１５、２０、３０、４０、６０、８０、１００、１２０度／秒）,每个刺激持续２０秒。用磁带机记录被试的视动性眼震信号,同时,记录被试视动性错觉出现的潜伏期和错觉量。视动性眼震信号在７Ｔ１７信息处理仪上进行脱机采样处理,错觉量用模糊集途径进行量化。主要结论如下：１．视动性眼震的快相速度、慢性速度、快相幅度、慢性幅度均随刺激速度增加而增大,在６０－１２０度／秒范围达到峰值后,基本维持稳定状态,而快慢相时间却有相反的变化趋势,其随刺激速度增加而减小,在６０度／秒达到最低值,然后略有回升。２．在５－１２０度／秒内,视动性错觉随刺激速度的增加而增大,呈直线上升。３．视动性眼震与视动性错觉不存在因果关系。低速度视动刺激下,当视动性眼震被抑制时,错觉量明显增大,说明视动性眼震减轻了视动性错觉。
