Extract

Figural after-effects are the observable results of a hypothetical process of satiation or inhibition which accompanies and follows the passage of neural currents consequent upon stimulation. Most of the work in this field has been on figural after-effects affecting contours. In this work an inspection figure is fixated for a fairly lengthy period of time; this is then withdrawn and two test figures are substituted. One of these test figures falls within the same area as the inspection figure while the other is well removed from this area. Differences in size between the two figures which are objectively equal are usually observed and are supposed to be a consequence of satiation set up by the inspection figure (McEwen, 1958).
