利用视觉周边线索在额平行平面内的直线平移运动,在线索运动轨迹的沿着不同位置上探测目标辨别,发现运动起始位置或其附近的目标辨别速度较慢(偏离中心4.2°)、相对于静态线索的起始(实验1)以及相对于沿运动轨迹进一步沿着呈现的目标(实验1和2)。目标歧视同样快速和准确的移动提示条件相对于静态提示条件的位置进一步沿着线索的运动轨迹(实验1)。此外,目标方向歧视没有减慢在相同的位置,一旦这个位置不再是运动开始的位置(实验3),在目标颜色歧视任务的性能没有减慢,即使在运动开始(实验4)。最后,我们发现,运动线索的起始位置被认为是被转移的方向线索的运动(实验5)。这些结果表明,注意力不能像运动刺激的运动轨迹上的其他位置那样快速或精确地转移到运动刺激的开始。
Using straight translatory motion of a visual peripheral cue in the frontoparallel plane, and probing target discrimination at different positions along the cue's motion trajectory, we found that target orientation discrimination was slower for targets presented at or near the position of motion onset (4.2° off centre), relative to the onset of a static cue (Experiment 1), and relative to targets presented further along the motion trajectory (Experiments 1 and 2). Target discrimination was equally fast and accurate in the moving cue conditions relative to static cue conditions at positions further along the cue's motion trajectory (Experiment 1). Moreover, target orientation discrimination was not slowed at the same position, once this position was no longer the motion onset position (Experiment 3), and performance in a target colour-discrimination task was not slowed even at motion onset (Experiment 4). Finally, we found that the onset location of the motion cue was perceived as being shifted in the direction of the cue's motion (Experiment 5). These results indicate that attention cannot be as quickly or precisely shifted to the onset of a motion stimulus as to other positions on a stimulus’ motion trajectory.
