先前的研究表明，3个月大的婴儿在噪音存在的情况下整合个体元素的能力尚不成熟。本研究通过一个新设计的婴儿线索范式，通过评估6个月大婴儿区分由定向Gabor块构成的圆形和方形轮廓的能力，考察了他们将单个元素整合到整体轮廓中的能力，从而延长了发育时间。如果婴儿区分了中央呈现的轮廓线索，那么他们的眼球运动将以高于偶然的速度正确预测随后的目标呈现。结果表明，婴儿能够整合轮廓并区分不同的形状，但是，与过去的研究一致，这个年龄段的这种能力还相当不成熟，只能忍受有限的噪音。(C) 2007 Elsevier Ltd.版权所有。
Previous research has indicated that the ability to integrate individual elements in the presence of noise is immature in 3-month-old infants. The present study extended the developmental timeline by investigating 6-month-olds' ability to integrate individual elements into whole contours through an assessment of their capability to discriminate circle and square contours constructed from oriented Gabor patches via a newly designed cueing paradigm for infants. If infants discriminate the centrally-presented contour cues, then their eye movements would correctly anticipate subsequent target presentation at a rate greater than chance. The results indicated that infants integrated the contours and discriminated the different shapes, but, consistent with past research, this ability is still fairly immature at this age, tolerating limited amount of noise.
