D4-4　The effect of visual target contrast on latency and amplitude of saccades

Abstract

The effect of target contrast on saccadic latency and amplitude was investigated. Participants were asked to gaze the visual targets presented randomly with different contrast and direction, while their saccadic eye movement data were collected as EOG signals. As a result, saccadic latency was affected by target contrast within the limited range regardless of the direction of saccadic movements, and saccadic amplitude was not affected by target contrast. The results partially indicated that the potential use of appropriate contrast can be designed as indices for changing the characteristics of saccadic movements.
