The crowding factor method applied to parafoveal vision.

abstract：:Apparent duration can be manipulated in a local region of visual field by long-term adaptation to motion or flicker (Johnston, Arnold, & Nishida, 2006). These effects show narrow spatial tuning (Ayhan, Bruno, Nishida, & Johnston, 2009), as well as retinotopic position dependency (Bruno, Ayhan, & Johnston, 2010), suppo...

What is learned when repeatedly switching between the visuomotor mappings: the absolute mappings or the relative shift between the mappings?
