Visual psychophysics

Manfred Fahle and Eberhart Zrenner


During the last year, a wealth of studies was published on visual psychophysics in normal observers, advancing our understanding of the function of the visual system. Here, both basic studies and clinical investigations are reviewed. Among the studies in "pure" psychophysics, we concentrate on those an binocular interactions (stereoscopic depth and rivalry), motion perception, attention and parallel perception, hyperacuity, visual persistence, and contrast and blur, as well as on color vision. In clinical psychophysics, studies dealing with glaucoma, retinitis pigmentosa, and the effects of neurologic disorders on visual perception are reviewed.
