知觉负荷的作用，在选择性注意的多维对象进行了调查，独立操纵负载沿着的任务相关和任务无关的尺寸在中央搜索阵列，这是两侧的一致，不一致，或中性的外围干扰。这些维度在捕捉注意力方面的相对自下而上的感知显着性在实验之间被操纵。当任务相关维度是字母的颜色，任务无关维度是字母的视觉形状时（实验1），字母形状知觉负荷的操纵对颜色反应的一致性效应模式没有影响，即，在较高的颜色知觉负荷下，一致性效应较小，而在较低的颜色知觉负荷下，一致性效应较大。当任务相关维度为字母的形状，任务无关维度为字母的颜色时（实验2），无论字母的形状负荷如何，在高颜色知觉负荷下对字母形状的反应均不存在一致性效应。当只有目标和侧翼被着色，而在中央阵列的干扰子没有（实验3），任务无关的颜色信息减少或消除了字母形状知觉负荷的影响，在响应的字母形状的一致性效应。这些发现表明，对多维物体的选择性注意遵循知觉负荷理论的一般原则，但自下而上的知觉显著性在注意资源在物体和维度上的分配中起主要作用。
The role of perceptual load in selective attention to multidimensional objects was investigated by independently manipulating the load along the task-relevant and the task-irrelevant dimensions in the central search array, which was flanked by congruent, incongruent, or neutral peripheral distractors. The relative bottom-up perceptual saliency of these dimensions in capturing attention was manipulated between experiments. When the task-relevant dimension was the color of the letter and the task-irrelevant dimension was the visual shape of the letter (Experiment 1), manipulation of the letter shape perceptual load had no impact upon the pattern of congruency effects in responding to the color, i.e., smaller congruency effects under higher color perceptual loads and larger congruency effects under lower color perceptual loads. When the task-relevant dimension was the shape of the letter and the task-irrelevant dimension was the color of the letter (Experiment 2), there were no congruency effects in responding to the letter shape under high color perceptual loads irrespective of the letter shape loads. When only the target and the flanker were colored whereas the distractors in the central array were not (Experiment 3), the task-irrelevant color information reduced or eliminated the impact of letter shape perceptual load on the congruency effects in responding to the letter shape. These findings suggested that selective attention to multidimensional objects follows the general principles suggested by the perceptual load theory, but the bottom-up perceptual saliency plays a primary role in the distribution of attentional resources over objects and dimensions.
