Asymmetry in the detection of shapes from shading in infants1

Abstract: We investigated 3‐ and 4‐month‐old infants’ sensitivity to differences defined by shading using a paired‐comparison familiarity/novelty preference procedure. Infants were familiarized with a pair of displays consisting of homogeneous shaded disks, and then were tested with two displays: the familiar display and a novel one containing shaded disks with reversed polarity (defined as the target). Experiment 1 examined two assumptions on discerning shapes from shading in infants by manipulating the orientations in the shading gradient of stimuli. When the orientation of the shading gradient was vertical, 4‐month‐old infants looked at the novel display for a longer time during the test trial. However, they failed to detect differences when the orientation of shading gradients was horizontal. Three‐month‐old infants did not detect differences in either orientation of the shading gradient. Experiment 2 examined asymmetry in the detection of convex versus concave shapes. Four‐month‐old infants failed to detect the target when the orientation of the shading grating was vertical and the target was convex. Taken with the results of Experiment 1, concave shapes were much easier to detect than convex shapes for 4‐month‐olds. This asymmetry suggests that 4‐month‐old infants process shading information in the same manner as adults.     

颜色类别知觉效应的机制：语言的作用

颜色类别知觉效应(Category Perception, CP效应)表明, 在颜色之间物理差异距离相等的前提下, 个体区分不同类别的颜色比区分同一类别的颜色更快、更准确。这一效应产生的机制成为普遍进化理论和Sapir-Whorf假设之间争论的重要证据。支持CP效应由语言驱动的学者提出了CP效应单侧化、受语言即时任务影响、跨语言研究和神经生理机制等证据, 以表明语言在CP效应中起决定性的作用; 支持CP效应具有普遍性的学者以CP效应双侧化、婴儿的CP效应、跨语言的反证等证据提出了质疑。近年来, 出现了第三种观点, 认为在颜色CP效应中语言驱动机制和普遍机制并存, 这种理论是普遍进化理论和Whorf假设的折衷观点。从支持CP效应由语言驱动的证据、支持CP效应独立于语言的证据以及支持两种机制并存的观点等三个方面入手, 可分析颜色CP效应的产生机制及语言在其中所起的作用, 未来研究可从概念系统渗入知觉系统的角度进行拓展。     

The Effect of Pink/Blue Clothing on Implicit and Explicit Gender‐Related Self‐Cognition and Attitudes Among Men

In many cultures worldwide, one stereotype emerges: Pink is associated with girls and blue is associated with boys. Based on the enclothed cognition theory, the present study examined the effects of men's pink clothing on gender‐related self‐cognition and sex‐role attitudes. Male Japanese participants wore either a pink or blue coat and completed a gender stereotype Implicit Association Test, a self‐rating scale, and gender attitude scales (a measure of egalitarian sex‐role attitude and the Ambivalent Sexism Inventory). Results showed that among participants with low self‐esteem, the implicit self–feminine association was stronger in the pink condition than in the blue condition. On the other hand, participants with high self‐esteem explicitly associated themselves more with power‐oriented traits compared with interpersonal‐oriented traits when they wore a pink coat compared with those who wore a blue coat. Additionally, participants in the pink condition expressed stronger egalitarian sex‐role attitudes and weaker benevolent sexism than those in the blue condition. We propose that men's pink clothing is a means of diminishing gender stereotypes and traditional sex‐role attitudes.     

Multiracial Identity,Color‐Blind Racial Ideology,and Discrimination: Professional Counseling Implications

Because of the expansive multiracial population growth in the United States, the authors explored multiracial identity integration (MII), color‐blind racial ideology (CBRI), and discrimination using regression analyses with 288 individuals. CBRI and discrimination significantly correlated and predicted MII, with 15.3% of the variance explained by discrimination and CBRI. Moderation analysis revealed that CBRI did not moderate the relationship between discrimination and MII. Continued research among multiracial individuals is recommended to better understand the CBRI and racial identity link.     

颜色词的语用关系影响颜色认知

在汉语中, 红、紫、蓝、绿都有各自的语言标签。但在日常语用中, “红”与“紫”比“蓝”与“绿”的语用关系更加密切。“红”与“紫”具有更多的联合表达, 具有更为类似的颜色感应。采用颜色相似性判断、颜色分类和颜色再认任务, 考察汉语母语者对“红–紫”色块和“蓝–绿”色块的认知, 探讨语用关系对颜色认知的影响。结果表明, 语用关系不影响汉语母语者的颜色相似性判断, 却影响颜色分类和颜色再认。与“蓝–绿”色块比, 汉语母语者在包含记忆成分任务中对“红–紫”色块具有认知劣势。整个研究表明, 由语用关系引起的颜色感应在颜色认知中起着重要调节作用, 记忆编码在此过程中起着直接作用。     

不同熟练度双语者的颜色范畴知觉效应：来自行为和ERP的证据

为研究语言对知觉的影响作用, 行为实验采用视觉搜索范式研究蒙汉双语者的颜色范畴知觉效应; 为进一步考察语言影响知觉的脑机制, 脑电实验采用Oddball范式研究蒙汉双语者的颜色范畴知觉效应。行为实验和脑电研究结果都发现, 在区分蒙古语中qinker和huhe色时, 低汉语水平的蒙汉双语者比高汉语水平者产生更强的颜色范畴效应, 蒙汉双语者的汉语水平影响颜色范畴知觉, 双语者所习得的第二语言范畴可以改变双语者母语的范畴, 语言能影响知觉的前注意阶段, 本研究支持了Spair-Whorf假设。     

Varieties of grapheme-colour synaesthesia: a new theory of phenomenological and behavioural differences

Recent research has suggested that not all grapheme-colour synaesthetes are alike. One suggestion is that they can be divided, phenomenologically, in terms of whether the colours are experienced in external or internal space (projector–associator distinction). Another suggestion is that they can be divided according to whether it is the perceptual or conceptual attributes of a stimulus that is critical (higher–lower distinction). This study compares the behavioural performance of 7 projector and 7 associator synaesthetes. We demonstrate that this distinction does not map on to behavioural traits expected from the higher–lower distinction. We replicate previous research showing that projectors are faster at naming their synaesthetic colours than veridical colours, and that associators show the reverse profile. Synaesthetes who project colours into external space but not on to the surface of the grapheme behave like associators on this task. In a second task, graphemes presented briefly in the periphery are more likely to elicit reports of colour in projectors than associators, but the colours only tend to be accurate when the grapheme itself is also accurately identified. We propose an alternative model of individual differences in grapheme-colour synaesthesia that emphasises the role of different spatial reference frames in synaesthetic perception. In doing so, we attempt to bring the synaesthesia literature closer to current models of non-synaesthetic perception, attention and binding.     

Parental and school influences upon the career development of poor youth of color

Critical career development tasks for adolescents include developing vocational expectations and a connection to the world of work. Given the sociopolitical barriers to the career development of poor Youth of Color, it is vital to identify contextual resources facilitative of their career development. The present study examines the impact of relational and instrumental parental support and instrumental school support upon vocational expectations and work salience among poor Youth of Color. Participants from the National Educational Longitudinal Study (NELS) were examined longitudinally from 12th grade to two years after they had finished high school. The obtained structural models suggested that relational and instrumental parental support had a direct effect upon work salience and instrumental parental support a significant indirect effect two years later. Instrumental school support and relational parental support had direct effects upon vocational expectations and nonsignificant indirect effects two years later. These findings illuminate contextual factors facilitative of vocational expectations and work salience, provide support for school-based career development programs, and suggest that incorporating relational and instrumental parental support could augment intervention programs for poor Youth of Color.     

Testing response-stimulus equivalence relations using differential responses as a sample

This study tested the notion that an equivalence relation may include a response when differential responses are paired with stimuli presented during training. Eight normal adults learned three kinds of computer mouse movements as differential response topographies (R1, R2, and R3). Next, in matching-to-sample training, one of the response topographies was used to select a comparison stimulus B (B1, B2, or B3) conditionally upon presentation of sample stimulus A (A1, A2, or A3), and to select stimulus D (D1, D2, or D3) conditionally upon presentation of stimulus C (C1, C2, or C3). After two sample-comparison-response relations (ABR and CDR) were established, 18 sample-comparison relations were tested (BA, DC, RA, RB, RC, RD, AC, CA, AD, DA, BC, CB, BD, DB, AA, BB, CC, and DD). In the RA, RB, RC, and RD tests, the differential responses (R1, R2, and R3) were used as sample stimuli. All subjects made class-consistent comparison selections in the tests. This study provides evidence that responses may become members of an equivalence class.     

Listening to Diversity Stories: Principles for Practice in Community Research and Action

Through a telling of key events in the history of the “Teen Action Center” (TAC), a drop-in youth center located in downtown “Unionville,” this story demonstrates how ‘youth’ is an important diversity category. The community conflict highlighted in this story centers around the 1997 arrest of TAC's Executive Director and two youth leaders (all Puerto Rican) because a small group of Latino and African-American youth was smoking cigarettes on the sidewalk in front of the Center. This conflict brings into focus divergent views on where Unionville's youth of color belong in the city, both physically and figuratively. The lessons learned in this story have wide application as Unionville, and other cities undergoing demographic transformation and economic decline, are likely to continue to experience these types of clashes, where the dominant paradigm of economic development overrides the realities, rights, and interests of marginalized groups.This article has been adapted from a chapter in my dissertation (Ross, 2002) Rebuilding Communities, Shaping Identities: The Impact of a Participatory Neighborhood Planning Process on Young, Low-Income Adolescents of Color, completed at the University of Massachusetts-Boston Public Policy Program.
