探索行为的早期发展进行了研究。一项研究记录了2至5个月大的婴儿自由探索的变化。另一项研究比较了3个月和4-5个月大的婴儿在光明或黑暗中操纵和探索物体时的情况（没有视觉控制探索）。第三项研究比较了3个月和4个月大的孩子在两个不同的物体在多个属性不同时的多模态探索。结果表明，显着的变化发生在2和5个月之间，相对自发的多模态探索的一个新的对象。对象探索变得越来越多模态。双手协调首先与口腔系统有关，后来在4个月时出现指法时根据视觉进行重组。3个月大的婴儿的操纵被证明是对象依赖的。控制早期对象的操作和功能的变化，在6个月大之前的手动操作的因素进行了讨论。
The early development of exploratory behavior was studied. One study documents changes in free exploration of infants aged from 2 to 5 months. Another compares 3- and 4-5 month-olds when manipulating and exploring an object in the light or in the dark (no visual control over exploration). The third study compares multimodal exploration in 3- and 4-month-olds when presented with two different objects varying in multiple properties. Results show that significant changes occur between 2 and 5 months, relative spontaneous multimodal exploration of a novel object. Object exploration becomes increasingly multimodal. Bimanual coordination is first linked to the oral system, later reorganized in reference to vision when fingering emerges by 4 months. Manipulation in 3-month-olds is shown to be object-dependent. Factors controlling early object manipulation and functional changes in manual action prior to 6 months of age are discussed.
