Sensitivity to second-order relational information (i.e., spatial relations among features such as the distance between eyes) is a vital part of achieving expertise with face processing. Prior research is unclear on whether infants are sensitive to second-order differences seen in typical human populations. In the current experiments, we examined whether infants are sensitive to changes in the space between the eyes and between the nose and the mouth that are within the normal range of variability in Caucasian female faces. In Experiment 1, 7-month-olds detected these changes in second-order relational information. Experiment 2 extended this finding to 5-month-olds and also found that infants detect second-order relations in upright faces but not in inverted faces, thereby exhibiting an inversion effect that has been considered to be a hallmark of second-order relational processing during adulthood. These results suggest that infants as young as 5 months are sensitive to second-order relational changes that are within the normal range of human variability. They also indicate that at least rudimentary aspects of face processing expertise are available early in life. 相似文献

Two experiments addressed the question of whether news reports depicting base‐rate data indicative of increasing population size over time would assuage the apprehension and victimization risk associated with another news story depicting frequency increases in a threatening phenomenon during the same time period. Men exposed to the population data manifested lower levels of apprehension and victimization risk than men not exposed to such data, but women showed no reduction in either apprehension and victimization risk than men not exposed to such data, but women showed no reduction in either apprehension or victimization risk after exposure to population data. This interaction was replicated in both experiments. Experiment 2 demonstrated that the same interaction can be produced using base‐rate data other than that depicting population increases over time and that the effects of the base‐rate stories are not merely a product of distraction from the threatening story. Differences in apprehension levels, information processing styles, mathematical problems solving skill, and sex role response sets were considered as alternative explanations for the interaction. 相似文献

We explored developmental changes in neural substrates for face processing, using fMRI. Children and adults performed a perceptual-matching
task with upright and inverted face and animal stimuli. Behaviorally, inversion disrupted face processing more than animal
processing for adults and older children. In line with this behavioral pattern, the left middle occipital gyrus showed a stronger
face than animal inversion effect in adults. Moreover, a superior aspect of this region showed a greater face inversion effect
in older than in younger children, indicating a developmental change in the processing of inverted faces. The visual regions
recruited for inverted face processing in adults also overlapped more with brain regions involved in the viewing of upright
objects than with regions involved in the viewing of upright faces in an independent localizer task. Hence, when faces are
inverted, adults recruit regions normally engaged for recognizing objects, possibly pointing to a role for the featural processing
of inverted faces. 相似文献
