早期的探索性行为被提出以促进儿童的学习，影响儿童的运动、认知、语言和社会发展。本研究将用于探索自我的行为与用于探索对象的行为相关联，然后通过对现有数据集的二次分析，将这两种类型的探索行为与3到24个月龄的运动、语言和认知测量纵向联系起来。研究对象为52名儿童(23名足月儿，29名早产儿)。之前发表的这一数据集的结果记录了每次评估中早产儿相对于足月儿的延迟。目前的结果与生命头两年的评估中的表现有关。他们表明，儿童用于自我探索的行为的发展轨迹与他们用于探索物体的行为的轨迹密切相关。自我和客体探索行为的轨迹与儿童运动、语言和认知发展的轨迹显著相关。具体地说，观察到与全球发展显著相关的是自我探索性头部抬起、中线头部和手的定位、手的张开和行为变异性，以及面向对象的双手握持、张嘴、看物体、敲击、操纵和转移，以及行为强度和变异性。这些结果表明，婴儿早期单独用身体进行的探索行为、用便携物品进行的探索行为和全球发展之间存在连续性。这些发现确定了特定的自我和物体探索行为，这些行为可以作为发育迟缓的早期指标，并可以通过干预措施来改善有发育迟缓风险的婴儿的运动、语言和认知结果。
Early exploratory behaviors have been proposed to facilitate children’s learning, impacting motor, cognitive, language, and social development. This study related the performance of behaviors used to explore oneself to behaviors used to explore objects, and then related both types of exploratory behaviors to motor, language, and cognitive measures longitudinally from 3 through 24 months of age via secondary analysis of an existing dataset. Participants were 52 children (23 full-term, 29 preterm). Previously published results from this dataset documented delays for preterm relative to full-term infants in each assessment. The current results related performance among the assessments throughout the first two years of life. They showed that the developmental trajectories of behaviors children used for self-exploration closely related to the trajectories of behaviors they employed to explore objects. The trajectories of both self and object exploration behaviors significantly related to trajectories of children’s motor, language, and cognitive development. Specifically, significant relations to global development were observed for self-exploratory head lifting, midline head and hand positioning, hand opening, and behavioral variability, as well as for object-oriented bimanual holding, mouthing, looking, banging, manipulating, and transferring of objects, as well as behavioral intensity and variability. These results demonstrate continuity among the early exploratory behaviors infants perform with their bodies alone, exploratory behaviors with portable objects, and global development. The findings identify specific self- and object-exploration behaviors that may serve as early indicators of developmental delay and could be targeted by interventions to advance motor, language, and cognitive outcomes for infants at risk for delay.
