The relationship between attentional shift and the compression of visual space before saccadic eye movements was investigated using a dual-task paradigm that required a target-directed saccade in combination with a discrimination task. The performance in discriminating the feature and displacement of a target briefly presented before the saccade was taken as a measure of both attention and the compression of visual space. Our results show that the ability of the feature discrimination is facilitated but the ability of the displacement discrimination is degraded when the saccade target is referred to the discrimination stimulus. Also, our results show that an object is not reduced by the compression of visual space before the saccade. It is suggested that attentional mechanism is independent of the mechanism of the compression of visual space.
