Illusory Increases in Font Size Improve Letter Recognition
通过两个实验发现，运动适应产生的膨胀后效能提升字母识别能力，而收缩后效则损害识别，表明视觉刺激的错觉大小变化可调节视敏度。
Visual performance of human observers depends not only on the optics of the eye and early sensory encoding but also on subsequent cortical processing and representations. In two experiments, we demonstrated that motion adaptation can enhance as well as impair visual acuity. Observers who experienced an expanding motion aftereffect exhibited improved letter recognition, whereas observers who experienced a contracting motion aftereffect showed impaired letter recognition. We conclude that illusory enlargement and shrinkage of a visual stimulus can modulate visual acuity.
