The term phi phenomenon is used in a narrow sense for an apparent motion that is observed if two nearby optical stimuli are presented in alternation with a relatively high frequency. In contrast to beta movement, seen at lower frequencies, the stimuli themselves do not appear to move. Instead, a diffuse, amorphous … Visa mer Wertheimer's classic experiments used two light lines or curves repeatedly presented one after the other using a tachistoscope. If certain, relatively short, intervals between stimuli were used, and the distance between … Visa mer As apparent phi movement is perceived by human’s visual system with two stationary and similar optical stimuli presented next to each other exposing successively with high frequency, there is also a reversed version of this motion, which is reversed phi illusion.
