Lavie's theory of attention proposes that the processing load in a relevant task determines the extent to which irrelevant distractors are processed. This theory was tested by asking participants in a study to perform linguistic tasks of low or high load while ignoring irrelevant visual motion in the periphery of the display. Although task and distractor were unrelated, both functional imaging of motion-related activity in cortical area V5 and psychophysical measures of the motion aftereffect showed reduced motion processing during high load in the linguistic task. These findings fulfill the prediction that perception of irrelevant distractors depends on the relevant processing load.
拉维的注意力理论提出，相关任务中的处理负荷决定了无关干扰物被处理的程度。在一项研究中，通过要求参与者在忽略显示屏周边无关视觉运动的同时执行低负荷或高负荷的语言任务，对这一理论进行了测试。尽管任务和干扰物无关，但对大脑皮层V5区与运动相关活动的功能成像以及运动后效的心理物理学测量均显示，在语言任务高负荷期间，运动处理能力下降。这些发现证实了无关干扰物的感知取决于相关处理负荷这一预测。
