Webphi phenomenon: [noun] apparent motion resulting from an orderly sequence of stimuli (such as lights flashed in rapid succession a short distance apart on a sign) without any … 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 … See more 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 … See more Phi phenomenon has long been confused with beta movement; however, the founder of Gestalt School of Psychology, Max Wertheimer, has distinguished the difference between them in 1912.

WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called … Webphi ( ϕ ), Cramer's V, Tschuprow's T, Cohen's w, and Pearson's C are effect sizes for tests of independence in 2D contingency tables. For 2-by-2 tables, phi, Cramer's V, Tschuprow's T, and Cohen's w are identical, and are equal to the simple correlation between two dichotomous variables, ranging between 0 (no dependence) and 1 (perfect dependence).
