Although infants and children show impressive face-processing skills, little research has focused on the conditions that facilitate versus impair face perception. According to the intersensory redundancy hypothesis (IRH), face discrimination, which relies on detection of visual featural information, should be impaired in the context of intersensory redundancy provided by audiovisual speech and enhanced when intersensory redundancy is absent. Evidence of this visual facilitation and intersensory interference was found in a recent study of 2-month-old infants (Bahrick, Lickliter, & Castellanos, in press). The present study is the first to extend tests of this principle of the IRH to children. Using a more difficult face recognition task in the context of a story, results from 4-year-old children paralleled those of infants and demonstrate that face discrimination in children is also facilitated by dynamic, visual-only exposure, in the absence of intersensory redundancy.
虽然婴儿和儿童表现出令人印象深刻的面孔处理技能，但很少有研究关注促进或损害面孔感知的条件。根据感觉冗余假说（IRH），依赖于视觉特征信息检测的面孔辨别能力，在视听语音提供的感觉冗余环境中会受到损害，而在感觉冗余不存在时则会增强。在对 2 个月大婴儿的一项最近研究中发现了这种视觉促进和感觉干扰的证据（Bahrick、Lickliter 和 Castellanos，即将出版）。本研究首次将 IRH 的这一原则的测试扩展到儿童。在故事的背景下使用更困难的面孔识别任务，4 岁儿童的结果与婴儿的结果相似，表明在没有感觉冗余的情况下，儿童的面孔辨别也会受到动态的、仅视觉的刺激的促进。
