当呈现视觉刺激（“提示”）并跟随一条线时，即使它在物理上同时呈现（“线运动效应”），该线也会被感知为从被提示的一侧快速增长。我们现在报告说，当提示以非视觉方式（例如听觉或体感）呈现时，可以观察到相同的线运动。从左侧或右侧扬声器发出蜂鸣声作为听觉提示，或者将电脉冲施加到放在 CRT 显示器左侧或右侧的手指作为体感提示，然后在两个可能的提示位置之间呈现线探针，听觉和体感提示都会导致线运动，因此线运动不能解释为模态内效应的变化，例如视觉表观运动。当操纵提示提前时间时，获得的时间课程三种提示模式的效果相似（实验 1），根据另一个实验（实验 2）的结果，细微的差异可以简单地用检测潜伏期来解释。最后，将直线运动任务与时间顺序判断任务进行比较，其中两个目标同时出现在有提示和无提示的一侧，并要求受试者判断哪个目标首先出现。结果，受试者体内的两个任务之间获得了类似的提示提前时间依赖性（实验3），因此，非视觉提示似乎促进了空间表征中附近视觉刺激的“预先进入”，与视觉提示的方式非常相似。这些影响应归因于模态非特定空间注意力，即不同位置的信息处理效率的“梯度”。 (C) 1997 爱思唯尔科学有限公司。
When a visual stimulus (the ''cue'') is presented and followed by a line, the line is perceived to grow rapidly from the cued side even when it is presented physically simultaneously (the ''line-motion effect''), We now report that the same line motion can be observed when the cue is presented in a non-visual modality, such as auditory or somatosensory. A beep sound was presented either from the left or the right speaker as an auditory cue, or an electric pulse was applied to a finger put on the left or the right side of a CRT display as a somatosensory cue, A line probe was then presented between the two possible cue positions, Both the auditory and the somatosensory cues led to line motion, thus the line motion could not be interpreted as a variation of within-modality effects, such as visual apparent motion, When the cue lead time was manipulated, the obtained time courses of the effects were similar across the three cue modalities (Experiment 1), The minor differences could be explained simply in Germs of latency of detection, according to results of another experiment (Experiment 2), Finally, the line-motion task was compared with a task of temporal order judgment, where two targets were presented simultaneously at the cued and the uncued sides, and the subject was asked to judge which of the targets had appeared first, As a result, similar dependencies on cue lead time were obtained between the two tasks within subjects (Experiment 3), Thus, the non-visual cue seems to facilitate ''prior entry'' of a visual stimulus nearby in the spatial representation, much the same way as a visual cue does. These effects should be attributed to modality non-specific spatial attention, i,e,, a ''gradient'' of information processing efficiency across various locations. (C) 1997 Elsevier Science Ltd.
