Mixture of easy trials enables transient and sustained perceptual improvements through priming and perceptual learning

Abstract The sense of vision allows us to discriminate fine details across a wide range of tasks. How to improve this perceptual skill, particularly within a short training session, is of substantial interest. Emerging evidence suggests that mixing easy trials can quickly improve performance in hard...
