Fast adaptation biases the perceived motion direction of a subsequently presented ambiguous test pattern (R. Kanai & F. A. Verstraten, 2005). Depending on both the duration of the adapting stimulus (ranging from tens to hundreds of milliseconds) and the du ...
Performance deteriorates when a target is flanked by contextual elements. For example, vernier thresholds increase when the vernier is flanked by lines. But when the lines are made part of a “good Gestalt”, like a rectangle, deterioration is reduced. Our e ...
Performance on a target can be modified by contextual elements. For example, thresholds strongly increase when a vernier is flanked by two lines. Increasing the number of flankers reduces contextual interference when the flankers are shorter or longer than ...
The spacing between target and flankers is one of the main factors of crowding. The closer the flankers are to the target, the stronger is crowding. Recently, it was proposed that crowding strength is determined by the distance between target and flanker c ...
