摘　　要：采用2种元素疏密程度的复合数字刺激和启动范式,7岁和11岁2个年龄组的小学生分别在注意整体水平和注意局部水平的条件下对探测刺激进行选择反应。结果发现元素疏密程度可以影响知觉优先,而知觉优先与整体局部水平间的负启动之间没有一致的发展关系,说明与负启动有关的注意分配机制可能比知觉组织发展的晚。In the present study, two groups 7-and 11-year-old subjects were asked to selectively attend to compound number＇s global or local level and judge whether it is larger or smaller than 5. The elements of compound numbers may be dense or sparse, The reaction time results showed that the sparsity of elements affected the perceptual precedence. But the between-level negative priming was not directly related to the perceptual precedence, which might develop later than perceptual precedence.
