摘　　要：许多研究认为 ,基本特征的觉察过程是平行加工的过程 ,它的探测与注意分配到某个位置没有关系。本实验通过不同线索分配注意 ,探讨了基本特征的平行加工与选择性注意的作用的关系。结果发现 :(1)基本特征的平行加工 ,可能受到注意分配影响的 ;(2 )注意分配的作用可能通过抑制干扰项的加工 ,而不仅仅只是通过促进靶子的加工而实现的。The present study aimed to explore whether there was an attentional ef fect on the parallel processing by means of different validities of cues. The re sults showed that even the searching of the basic features was preattentive codi ng in parallel display, and the reactive time was highly influenced in the locat ion of attention. The effect of attentional location could be obtained though th e inhibition of the distractor rather than the inprovement of the target proces sing. The possible reasons were discussed.
