研究表明,若隐若现的动作代表了一种特殊的注意力捕捉刺激,这是由于行为的紧迫性:需要对环境中向我们移动的物体采取行动。特别是,有一种理论认为,与后退运动相比,隐现运动对目标的更快反应时间是由后注意、运动启动过程驱动的,这超出了其他刺激品质(如颜色弹出)所产生的注意捕获效应。本研究通过一个相对大小判断任务来验证这一理论,在这个任务中,目标是通过隐现和后退的光流场来预先提示的。结果显示,在隐现流场的提示下,目标的感知大小有系统地增加,这与先前使用开始提示的注意力捕获研究一致。这些结果挑战了将隐约动作的行为变化仅仅归因于运动启动的理论。
Studies suggest looming motion represents a special class of attentional capture stimulus due to behavioral urgency: the need to act upon objects moving toward us in an environment. In particular, one theory suggests that faster reaction times to targets cued by looming relative to receding motion are driven by post-attentional, motor-priming processes beyond the attentional capture effects seen with other stimulus qualities such as color pop-out. The present study tested this theory using a relative size judgment task where targets were pre-cued by looming and receding optic flow fields. Results show systematic increases in the perceived size of targets that were cued by looming flow fields, consistent with previous attentional capture studies using onset cues. These results challenge theories attributing behavioral changes from looming motion to motor-priming alone.
