婴儿如何决定在悬崖边缘做什么？婴儿可以使用两种信息来源来指导他们的行动：他们自己的探索活动产生的感知信息和他们的照顾者提供的社会信息。目前的研究探讨了运动经验的作用，在使用社会信息的鼓励和劝阻，为下降下降。30名婴儿的母亲（有经验的12个月大的爬行者，新手12个月大的步行者，有经验的18个月大的步行者）鼓励和劝阻下降的梯度下降（安全的“步骤”和危险的“悬崖”）。初学者比有经验的爬行者和步行者更频繁地下降，并在试图走过不可能的高悬崖时摔倒。所有婴儿都表现出整合知觉和社会信息的证据，但运动经验影响婴儿对社会信息的使用，特别是在危险的下降。有经验的爬行者和步行者选择性地推迟社会信息时，感知信息是模糊的。相比之下，初学走路的人不一致地接受母亲的建议，只有在极端的下降。
How do infants decide what to do at the brink of a precipice? Infants could use two sources of information to guide their actions: perceptual information generated by their own exploratory activity and social information offered by their caregivers. The current study investigated the role of locomotor experience in using social information—both encouragement and discouragement—for descending drop-offs. Mothers of 30 infants (experienced 12-month-old crawlers, novice 12-month-old walkers, and experienced 18-month-old walkers) encouraged and discouraged descent on a gradation of drop-offs (safe “steps” and risky “cliffs”). Novice walkers descended more frequently than experienced crawlers and walkers and fell while attempting to walk over impossibly high cliffs. All infants showed evidence of integrating perceptual and social information, but locomotor experience affected infants’ use of social messages, especially on risky drop-offs. Experienced crawlers and walkers selectively deferred to social information when perceptual information is ambiguous. In contrast, novice walkers took mothers’ advice inconsistently and only at extreme drop-offs.
