Twenty-two pairs of typically developing toddlers (M=24.32 months) and their mothers were observed in a play-room solving puzzles during 30 min. The target of the observations was hand-taking gesture. Researchers have thought that this gesture is rare among typically developing children and is more frequent among autistic children. Ten in 22 children showed this gesture in only 30 min. They should know "I can not do it by myself, but my mother can do it." When we can assume that children know others' mental mechanism, it might be the origins of a theory of mind.
22 对正常发育的幼儿（M=24.32 个月）及其母亲在游戏室中观察了 30 分钟，解决拼图。观察的目标是手取姿势。研究人员认为，这种姿势在正常发育的儿童中很少见，而在自闭症儿童中更为常见。在 22 个孩子中，有 10 个孩子在 30 分钟内只展示了这个姿势。他们应该知道“我自己做不到，但我妈妈可以做。”当我们可以假设孩子知道他人的心理机制时，这可能是心理理论的起源。
