Theory of mind refers to the ability to reason about others' beliefs and to understand others' behaviour in terms of those beliefs. A large body of previous research has examined theory of mind reasoning in young children using false belief tasks, but tasks to examine this capacity during infancy have only been developed more recently. This research used stimuli developed by Kovács, et al., Science, 2010, 330, 1830–1834, to measure looking time to an agent with a false belief in infants aged 6 and 7 months. Using an eye-tracking procedure, we found looking behaviour consistent with 7-month-olds distinguishing an agent who has a false belief from one who has a true belief, consistent with the results reported by Kovács et al. We did not find evidence of this looking preference among 6-month-olds.

在 7 个月但不是 6 个月大时更长时间地寻找具有错误信念的代理人

心智理论是指推理他人信念并根据这些信念理解他人行为的能力。大量先前的研究已经使用错误信念任务检查了幼儿的思维推理理论，但是在婴儿期检查这种能力的任务是最近才发展起来的。这项研究使用了 Kovács 等人在Science , 2010, 330, 1830–1834 中开发的刺激物，以测量对 6 个月和 7 个月大的婴儿抱有错误信念的代理人的注视时间。使用眼动追踪程序，我们发现与 7 个月大的婴儿的看行为一致，可以区分持有错误信念的代理人和持有真实信念的代理人，这与 Kovács 等人报告的结果一致。我们没有在 6 个月大的婴儿中发现这种外观偏好的证据。
