The authors explored whether 5- to 6-month-old infants were sensitive to perceptual information and how they used perception as a recognition cue to search for a hidden object. In addition, the authors categorized and examined infant grasp by developmental effectiveness to determine any impact on infant search behaviors. In a within-participants design, 20 infants were presented with a toy in 2 occluder conditions. The toy was hidden under either a thick, camouflaging cloth or a thin, semitransparent cloth. The data revealed significant effects of perceptual sensitivity, age, and motor sophistication on search tasks. The results suggest that motor competence might be a limiting factor in infants' abilities to link motoric responses to notions about an object.
作者们探究了5至6个月大的婴儿是否对感知信息敏感,以及他们如何将感知作为识别线索来寻找隐藏物体。此外,作者们根据发育有效性对婴儿抓握进行了分类和研究,以确定其对婴儿搜索行为的任何影响。在一项被试内设计中,20名婴儿在两种遮挡条件下接触一个玩具。玩具被藏在一块厚的、有伪装作用的布或一块薄的、半透明的布下面。数据显示,感知敏感性、年龄和运动成熟度对搜索任务有显著影响。结果表明,运动能力可能是婴儿将运动反应与物体概念联系起来的能力的一个限制因素。
