We examined the development of visual cue integration in a desktop working-memory task using boxes with different visual action cues (opening actions) and perceptual surface cues (colours, monochromatic textures, or images of faces). Children had to recall which box held a hidden toy, based on (a) the action cue, (b) the surface cue, or (c) a conjunction of the two. Results from three experiments show a set of asymmetries in children's integration of action and surface cues. The 18-24-month-olds disregarded colour in conjunction judgements with action; 30-36-month-olds used colour but disregarded texture. Images of faces were not disregarded at either age. We suggest that 18-24-month-olds' disregard of colour, seen previously in reorientation tasks (Hermer & Spelke, 1994), may represent a general phenomenon, likened to uneven integration between the dorsal and ventral streams in early development.
我们在一项桌面工作记忆任务中，使用带有不同视觉动作线索（打开动作）和感知表面线索（颜色、单色纹理或面部图像）的盒子，研究了视觉线索整合的发展情况。儿童必须根据（a）动作线索、（b）表面线索或（c）两者的结合，回忆哪个盒子里藏着玩具。三项实验的结果显示，儿童在动作和表面线索整合方面存在一系列不对称性。18至24个月大的儿童在与动作的联合判断中忽略了颜色；30至36个月大的儿童使用了颜色，但忽略了纹理。两个年龄段的儿童都没有忽略面部图像。我们认为，18至24个月大的儿童对颜色的忽略，先前在重新定向任务中也有发现（赫默和斯佩尔克，1994），这可能代表了一种普遍现象，类似于早期发育中背侧和腹侧流之间的不均衡整合。
