两个实验研究了婴儿是否可以利用他们丰富的社会知识将单个物体的表征绑定到更大的社会单位中，从而克服工作记忆的三项限制。在实验1中，16个月大的婴儿（n = 32）记得多达四个隐藏的娃娃时，面对和相互作用的娃娃对，但不是当他们面对和互动的婴儿，这表明婴儿组成社会对娃娃。在实验2（n = 16）中，婴儿未能记住四个娃娃，当他们面对对方没有互动，这表明娃娃之间的互动是必要的驱动组块。这项工作通过证明婴儿可以使用社会线索来扩展记忆，从而弥合了社会认知和记忆之间的差距。
Two experiments investigated whether infants can use their rich social knowledge to bind representations of individual objects into larger social units, thereby overcoming the three-item limit of working memory. In Experiment 1, 16-month-olds (n = 32) remembered up to four hidden dolls when the dolls had faced and interacted with each other in pairs, but not when they faced and interacted with the infant, suggesting that infants chunked the dolls into social pairs. In Experiment 2 (n = 16), infants failed to remember four dolls when they faced each other without interacting, indicating that interaction between the dolls was necessary to drive chunking. This work bridges a gap between social cognition and memory by demonstrating that infants can use social cues to expand memory.
