两个独立的任务，对象操作和视觉匹配，被用来检查之间的关系，发展手动动作技能和注意联运对象属性在3.5个月和5.5个月大。虽然处理技能随着年龄的增长而提高，但年龄较大的婴儿表现出更多的不同操作，匹配任务没有年龄差异。当分组的处理技能，技能和事件类型之间的显着相互作用，发现两个年龄组相结合，并为5.5个月大的孩子。社会事件的听觉视觉匹配并没有随着处理技能的不同而变化，而物体事件的视觉听觉匹配则不同。在较高的技能水平的婴儿类似的社会和对象事件的反应，而技能较低的婴儿的匹配偏好较弱的对象事件。这些发现表明，婴儿增加了他们对物体的听觉和视觉特性的注意力，因为这些信息对指导新的行动变得有用。这种影响是独立的年龄，由于相当大的个体差异的发展对象处理技能。
Two independent tasks, object manipulation and auditory-visual matching, were used to examine the relationship between developing manual action skills and attention to intermodal object properties in 3.5- and 5.5-month-olds. Although handling skills improved with age, with older infants demonstrating more varied manipulation, there were no age differences for the matching task. When grouped by handling skills, a significant interaction between skill and event type was found for the two age groups combined and for 5.5-month-olds alone. Auditory-visual matching of social events did not vary with handling skills, whereas auditory-visual matching of object events did. Infants at higher skill levels responded similarly to social and object events, whereas less skilled infants' matching preferences were weaker for object events. These findings indicate that infants increase their attention to auditory and visual properties of objects as this information becomes useful for guiding new actions. This effect is independent of age due to considerable individual variability in the development of object handling skills.
