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.
我们研究了空间频率和对比度对针对单个伽柏补丁的扫视潜伏期的影响。扫视潜伏期随对比度的增加而缩短，随空间频率的增加而延长。观察到的潜伏期变化在定性上与手动反应时间的变化相似。对于单目标检测，我们的研究结果突出了支持扫视反应和手动反应的视觉过程的相似性。
