摘要 通过内源性的注意线索来操纵空间注意的分配方式,考察注意在运动诱发视盲(motion-induced blindness,MIB)现象中的调控作用.研究结果发现,在上视野和左下视野中,被试在集中注意条件下(注意单侧视野目标)比分散注意条件下(注意双侧视野目标)体验到更多的MIB现象;在下视野发现了MIB现象中注意调控作用的半球不对称性,在集中注意条件下,左下视野比右下视野发生了更多的MIB现象,而上视野没有出现半球不对称性;下视野集中注意条件下MIB的增加主要表现为每次发生MIB的平均时间长度的增加,而在上视野中,除了表现为每次发生MIB的平均时间长度的增加,还表现为MIB发生次数的增加.这些研究结果表明,MIB现象中注意的调控作用在上下视野表现出不同的模式.
