在不确定的情况下,如下降具有挑战性的斜坡,社会信号从照顾者可以为婴儿提供指导行动的重要信息。先前的研究表明,18个月大的走路婴儿只有在跌倒风险不确定的情况下才会有选择地使用社会信息。实验一的目的是改变婴儿走下坡路的不确定区域。与赤脚或穿标准的绉纱底鞋相比,拖鞋特氟龙底鞋大大削弱了18个月大的婴儿走下坡路的能力,将不确定性区域转移到较浅的斜坡范围。在实验2中,婴儿穿着特氟龙鞋底的鞋子走下坡路,因为他们的母亲鼓励和劝阻他们走路。婴儿在浅坡上依赖社会信息,即使是在0°,在特氟龙鞋底的鞋子中成功行走的概率是不确定的。研究结果表明,婴儿对社会信息的使用是动态调整的情境因素和他们目前的能力状态。
In uncertain situations such as descending challenging slopes, social signals from caregivers can provide infants with important information for guiding action. Previous work showed that 18- month-old walking infants use social information selectively, only when risk of falling is uncertain. Experiment 1 was designed to alter infants’ region of uncertainty for walking down slopes. Slippery Teflon-soled shoes drastically impaired 18-month-olds’ ability to walk down slopes compared with walking barefoot or in standard crepe-soled shoes, shifting the region of uncertainty to shallower range of slopes. In Experiment 2, infants wore Teflon-soled shoes while walking down slopes as their mothers encouraged and discouraged them from walking. Infants relied on social information on shallow slopes, even at 0°, where the probability of walking successfully was uncertain in the Teflon-soled shoes. Findings indicate that infants’ use of social information is dynamically attuned to situational factors and the state of their current abilities.
