  abstract  = {During the first year of life, infants undergo perceptual narrowing in the domains of speech and face perception. This is typically characterized by improvements in infants' abilities in discriminating among stimuli of familiar types, such as native speech tones and same-race faces. Simultaneously, infants begin to decline in their ability to discriminate among stimuli of types with which they have little experience, such as nonnative tones and other-race faces. The similarity in time-frames during which perceptual narrowing seems to occur in the domains of speech and face perception has led some researchers to hypothesize that the perceptual narrowing in these domains could be driven by shared domain-general processes. To explore this hypothesis, we tested 53 Caucasian 9-month-old infants from monolingual German households on their ability to discriminate among non-native Cantonese speech tones, as well among same-race German faces and other-race Chinese faces. We tested the infants using an infant-controlled habituation-dishabituation paradigm, with infants' preferences for looking at novel stimuli versus the habituated stimuli (dishabituation scores) acting as indicators of discrimination ability. As expected for their age, infants were able to discriminate between same-race faces, but not between other-race faces or non-native speech tones. Most interestingly, we found that infants' dishabituation scores for the non-native speech tones and other-race faces showed significant positive correlations, while the dishabituation scores for non-native speech tones and same-race faces did not. These results therefore support the hypothesis that shared domain-general mechanisms may drive perceptual narrowing in the domains of speech and face perception.},

  abstract  = {During social interactions, individuals rapidly and automatically judge others' trustworthiness on the basis of subtle facial cues. To investigate the behavioral and neural correlates of these judgments, we conducted 2 studies: 1 study for the construction and evaluation of a set of natural faces differing in trustworthiness (Study 1: n = 30) and another study for the investigation of event-related potentials (ERPs) in response to this set of natural faces (Study 2: n = 30). Participants of both studies provided highly reliable and nearly identical trustworthiness ratings for the selected faces, supporting the notion that the discrimination of trustworthy and untrustworthy faces depends on distinct facial cues. These cues appear to be processed in an automatic and bottom-up-driven fashion because the free viewing of these faces was sufficient to elicit trustworthiness-related differences in late positive potentials (LPPs) as indicated by larger amplitudes to untrustworthy as compared with trustworthy faces. Taken together, these findings suggest that natural faces contain distinct cues that are automatically and rapidly processed to facilitate the discrimination of untrustworthy and trustworthy faces across various contexts, presumably by enhancing the elaborative processing of untrustworthy as compared with trustworthy faces.
