To examine the influences of facial versus vocal cues on infants' behavior in a potentially threatening situation, 12-month-olds on a visual cliff received positive facial-only, vocal-only, or both facial and vocal cues from mothers. Infants' crossing times and looks to mother were assessed. Infants crossed the cliff faster with multimodal and vocal than with facial cues, and looked more to mother in the Face Plus Voice compared to the Voice Only condition. The findings suggest that vocal cues, even without a visual reference, are more potent than facial cues in guiding infants' behavior. The discussion focuses on the meaning of infants' looks and the role of voice in development of social cognition.
为了研究在潜在威胁情境中面部线索与声音线索对婴儿行为的影响，让12个月大的婴儿在视觉悬崖上接受来自母亲的仅面部积极线索、仅声音积极线索或面部与声音的双重积极线索。对婴儿的穿越时间以及看向母亲的情况进行了评估。与仅面部线索相比，婴儿在多模态和声音线索条件下穿越悬崖的速度更快，并且与仅声音条件相比，在面部加声音条件下婴儿看向母亲的次数更多。研究结果表明，即使没有视觉参照，声音线索在引导婴儿行为方面比面部线索更有效。讨论集中在婴儿注视的意义以及声音在社会认知发展中的作用。
