视觉显着性地图被假定为介导的目标选择决定在一个电机非特异性的方式，因此，调制显着性影响是/否目标检测或左/右定位响应手动按键搜索任务，以及眼睛或骨骼运动的目标。虽然被广泛接受，但这一核心假设几乎没有心理物理学证据。已知至少有四种显著性调制会影响特征单例的视觉搜索速度：（i）特征对比度，（ii）交叉试验维度序列和（iii）目标维度的语义预提示，以及（iv）维度目标冗余。如果显著性也指导手动指向运动，那么它们的启动延迟（和持续时间）应该受到同样的四种显著性操作的影响。四个实验，每个检查这些操作之一，揭示了这种情况。因此，这些效应独立于用信号通知感知决定所需的运动响应（例如，定向手动指向以及简单的是/否检测响应）。这支持了运动非特异性显着图的概念，它引导了内隐注意以及明显的眼睛和手的运动。
Visual salience maps are assumed to mediate target selection decisions in a motor-unspecific manner; accordingly, modulations of salience influence yes/no target detection or left/right localization responses in manual key-press search tasks, as well as ocular or skeletal movements to the target. Although widely accepted, this core assumption is based on little psychophysical evidence. At least four modulations of salience are known to influence the speed of visual search for feature singletons: (i) feature contrast, (ii) cross-trial dimension sequence and (iii) semantic pre-cueing of the target dimension, and (iv) dimensional target redundancy. If salience guides also manual pointing movements, their initiation latencies (and durations) should be affected by the same four manipulations of salience. Four experiments, each examining one of these manipulations, revealed this to be the case. Thus, these effects are seen independently of the motor response required to signal the perceptual decision (e.g., directed manual pointing as well as simple yes/no detection responses). This supports the notion of a motor-unspecific salience map, which guides covert attention as well as overt eye and hand movements.
