Apparent Size as a Determiner of Figural After‐effects. Iii

Abstract

Kolehmainen, K. Apparent size as a determiner of figural after‐effects. 111. Scand. J. Psychol., 1969, 10, 71–73.—Two rectangles were presented as an inspection figure in a gradient drawing, one appearing to be behind the fixation point and the other in front of it, because of the gradient effect. Test figures (circles) appeared to differ in size after inspection of this pattern. It is argued that this result supports the explanation suggested for the results of the earlier experiments in the present series (1968) that size‐changes of the test figures in this kind of situation are connected with an after‐effect in the third dimension.
