The many faces of configural processing 总被引:1,自引:0,他引:1
Adults' expertise in recognizing faces has been attributed to configural processing. We distinguish three types of configural processing: detecting the first-order relations that define faces (i.e. two eyes above a nose and mouth), holistic processing (glueing the features together into a gestalt), and processing second-order relations (i.e. the spacing among features). We provide evidence for their separability based on behavioral marker tasks, their sensitivity to experimental manipulations, and their patterns of development. We note that inversion affects each type of configural processing, not just sensitivity to second-order relations, and we review evidence on whether configural processing is unique to faces. 相似文献

Capacity limits in linguistic short-term memory (STM) are typically measured with forward span tasks in which participants are asked to recall lists of words in the order presented. Using such tasks, native signers of American Sign Language (ASL) exhibit smaller spans than native speakers ([Boutla, M., Supalla, T., Newport, E. L., & Bavelier, D. (2004). Short-term memory span: Insights from sign language. Nature Neuroscience, 7(9), 997-1002]). Here, we test the hypothesis that this population difference reflects differences in the way speakers and signers maintain temporal order information in short-term memory. We show that native signers differ from speakers on measures of short-term memory that require maintenance of temporal order of the tested materials, but not on those in which temporal order is not required. In addition, we show that, in a recall task with free order, bilingual subjects are more likely to recall in temporal order when using English than ASL. We conclude that speakers and signers do share common short-term memory processes. However, whereas short-term memory for spoken English is predominantly organized in terms of temporal order, we argue that this dimension does not play as great a role in signers' short-term memory. Other factors that may affect STM processes in signers are discussed. 相似文献

In adults, facial identity is coded by opponent processes relative to an average face or norm, as evidenced by the face identity aftereffect: adapting to a face biases perception towards the opposite identity, so that a previously neutral face (e.g. the average) resembles the identity of the computationally opposite face. We investigated whether children as young as 8 use adaptive norm-based coding to represent faces, a question of interest because 8-year-olds are less accurate than adults at recognizing faces and do not show the adult neural markers of face expertise. We found comparable face identity aftereffects in 8-year-olds and adults: perception of identity in both groups shifted in the direction predicted by norm-based coding. This finding suggests that, by 8 years of age, the adaptive computational mechanisms used to code facial identity are like those of adults and hence that children's immaturities in face processing arise from another source. 相似文献

This pilot study examined associations among asthma status, gender, self-competence, and depressed mood across 2 years of middle childhood in a sample of 57 urban children. Results revealed no differences across health status in self-competence and depressed mood. Girls showed a significant increase in levels of self-competence from Year -1 to 2. Higher levels of self-competence were associated with lower levels of depressed mood at Year 1, at Year 2, and from Year 1 to 2. Self-competence accounted for a larger amount of the variance in depressed mood for girls than for boys. Changes in levels of self-competence were significantly associated with changes in depressed mood for girls only. Results suggest meaningful gender-based differences in the socioemotional trajectories of school-aged children, which should be considered when designing preventative interventions in urban environments. 相似文献

The role of dual categorization and relative ingroup prototypicality in reparations to a minority group: An examination of empathy and collective guilt as mediators 下载免费PDF全文

In the current study, we investigate factors that facilitate or otherwise obstruct reparations of a perpetrating group (i.e. Muslims) to a victim group (i.e. Christians). The study (N = 200) reveals that among Muslim participants, the role of dual Abrahamic categorization in positively predicting reparation attitude towards Christians was mediated by the first group's prosocial emotions of empathy and collective guilt towards the latter group. In addition, relative Muslim prototypicality negatively predicted dual Abrahamic categorization and each of the two prosocial emotions. Empathy and collective guilt in turn mediated the role of relative ingroup prototypicality in negatively predicting reparation attitude. Moreover, as hypothesized, we found that the roles of empathy and collective guilt in predicting reparation intention, as manifested in participants' willingness to engage in collective action on behalf of the victim group, were not significant on their own, but were mediated by reparation attitude. These findings shed light on the importance of the relationship between the perpetrating group's shared identity with the victim group, reduced ingroup focus and its support for making reparations to the victim group. Theoretical implications, study limitations and practical strategies highlighting how to decrease relative Muslim prototypicality are discussed. 相似文献

We used a staircase procedure to test sensitivity to (1) global motion in random-dot kinematograms moving at 4° and 18° s(-1) and (2) biological motion. Thresholds were defined as (1) the minimum percentage of signal dots (i.e. the maximum percentage of noise dots) necessary for accurate discrimination of upward versus downward motion or (2) the maximum percentage of noise dots tolerated for accurate discrimination of biological from non-biological motion. Subjects were adults and children aged 6-8, 9-11, and 12-14 years (n = 20 per group). Contrary to earlier research, results revealed a similar, long developmental trajectory for sensitivity to global motion at both slower and faster speeds and for biological motion. Thresholds for all three tasks improved monotonically between 6 and 14 years of age, at which point they were adult-like. The results suggest that the extrastriate mechanisms that integrate local motion cues over time and space take many years to mature. 相似文献

The aim of this paper was to study the construct validity of the Affect in Play Scale, an empirically based measure of pretend play, in a group of 519 Italian children ages 6 to 10 years. In confirmatory factor analysis, a correlated two-factor structure with a cognitive and an affective factor was identified. Possible differences in factor scores by sex and age were investigated but no significant differences were found. 相似文献

Many letters of the alphabet are consistently mapped to specific colors in English-speaking adults, both in the general population and in individuals with grapheme-color synaesthesia who perceive letters in color. Here, across six experiments, we tested the ubiquity of the color/letter associations with typically developing toddlers, literate children, and adults. We found that pre-literate children associate O with white and X with black and discovered that they also associate I and ameboid nonsense shapes with white; Z and jagged nonsense shapes with black; and C with yellow; but do not make a number of other associations (B blue; Y yellow; A red; G green) seen in literate children and adults. The toddlers' mappings were based on the shape and not the sound of the letter. The results suggest that sensory cortical organization initially binds specific colors to some specific shapes and that learning to read can induce additional associations, likely through the influence of higher order networks as letters take on meaning. 相似文献

Differences across individuals in both 2D:4D, the ratio of the lengths of the 2nd-4th digit, and in otoacoustic emissions (OAEs), have been hypothesized to arise from differences in androgen exposure prenatally. Contrary to this hypothesis, however, McFadden and Shubel (2003) found no significant correlation between digit-ratios and OAE production. To further investigate the hypothesis of a common developmental origin, the current study assessed correlations between individual differences in 2D:4D and OAEs in 131 normally-hearing adults. All possible ratios of the 2nd, 3rd, 4th, and 5th digits were computed and OAEs, both spontaneously produced and in response to audible clicks, were measured. Observed correlations between digit length ratios and OAEs were largely nonsignificant. No significant correlations were found between 2D:4D and any of the five OAE measures. Fundamental differences in developmental timing and duration, postnatal influences, or factors other than prenatal androgens may explain the lack of associations. 相似文献
