===Thaumatrope===
In April 1825 the first ''[[Thaumatrope]]'' was published by W. Phillips (in anonymous association with [[John Ayrton Paris]]).<ref name="Herbert">{{cite web |url=http://www.stephenherbert.co.uk/thaumatropeTEXT1.htm |last=Herbert |first=Stephen |title=Wheel of Life - The Taumatrope |access-date=2017-02-26 |archive-date=2014-05-05 |archive-url=https://web.archive.org/web/20140505163311/http://www.stephenherbert.co.uk/thaumatropeTEXT1.htm |url-status=usurped }}</ref> The fact that the pictures on either side of the twirling disc seem to blend together into one image has often falsely been presented as an illustration of the effect of persistence of vision (the fusion instead depends on stroboscopic interruptions and the compatibility of the mental impressions of the two alternating pictures).

The differences between impressions of quick alternations of two figures –depending on [[tachistoscope]] frequencies, distance between the figures, and/or variance in shapes– was studied by [[Max Wertheimer]] in 1912.<ref name=Wertheimer/> These experiments inspired the theories of [[Gestalt psychology]].
