该研究利用空间线索技术的实验模式 ,考察跨视觉和听觉通道的内源性选择注意与外源性选择性注意的相互关系。实验结果表明 :( 1)听觉中央线索在较长的SOA(至少 5 0 0毫秒 )条件下 ,可以引导内源性空间选择性注意 ; 同时外周线索突现也能自动化地吸引部分注意资源。 ( 2 )听觉和视觉选择注意是分离的加工通道 ,但二者之间存在相互联系

Studies of mechanisms underlying orienting of attention in visual space usually provide subjects with advance cues. These cues indicate the probable locations of targets to facilitate localizing and discriminating the targets. Symbolic central cues and direct peripheral cues are believed to activate different endogenous and exogenous modes of orienting. Endogenous attention involves voluntary orienting response to symbolic indicators,such as a central arrow (central cue);and exogenous attention involves ref...
