先前对联合物体活动的发展描述确定了大约9- 12个月的质的转变。在一项26对儿的纵向研究中，对所有凝视和手动活动（10 Hz）的目标编码了4、6、9和12个月时关节物体相互作用的视频。在12个月时，婴儿将他们的感觉运动模式分配给父母处理的物体和婴儿控制的其他物体。分析揭示了第一年分布式联合对象活动的新轨迹。在4个月大的时候，婴儿主要看和操作一个物体，通常是由他们的母亲拿着。在6到9个月之间，婴儿越来越多地将他们的视觉和触觉模式分离开来，并将他们的注意力分配给母亲和他们自己所持有的物体。这些以前未报告的发展，在分布的多模态对象活动可能会弥合差距，以协调联合活动之间的6和12个月。
Previous developmental accounts of joint object activity identify a qualitative shift around 9-12months. In a longitudinal study of 26 dyads, videos of joint object interactions at 4, 6, 9, and 12months were coded for all targets of gaze and manual activity (at 10Hz). At 12months, infants distribute their sensorimotor modalities between objects handled by the parent and others controlled by the infant. Analyses reveal novel trajectories in distributed joint object activity across the 1st year. At 4months, infants predominantly look at and manipulate a single object, typically held by their mothers. Between 6 and 9months, infants increasingly decouple their visual and haptic modalities and distribute their attention between objects held by their mothers and by themselves. These previously unreported developments in the distribution of multimodal object activity might bridge the gap to coordinated joint activity between 6 and 12months.
