The influence of spatial frequency and contrast on saccade latencies.

Casimir J H Ludwig¹, Iain D Gilchrist, Eugene McSorley.

Abstract

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. Copyright 2004 Elsevier Ltd.
