我们描述了空间频率和对比度对单个 Gabor 补丁的扫视延迟的影响。扫视延迟随着对比度的变化而减少，并随着空间频率的增加而增加。观察到的延迟变化在质量上与手动反应时间观察到的相似。对于单个目标检测，我们的研究结果强调了支持扫视和手动响应的视觉过程的相似性。 (C) 2004 Elsevier Ltd. 保留所有权利。
We characterised the impact of spatial frequency and contrast on saccade latencies to single Gabor patches. Saccade latencies decreased as a function of contrast, and increased with spatial frequency. The observed latency variations are qualitatively similar to those observed for manual reaction times. For single target detection, our findings highlight the similarity in the visual processes that support both saccadic and manual responses. (C) 2004 Elsevier Ltd. All rights reserved.
