Abstract
Used illusion decrement to explore the relative contributions of structural factors and cognitive processing factors to the commonly found age differences in the magnitude of the Muller-Lyer illusion. A total of 160 7-, 9-, 11-, and 21-yr-olds judged the standard Brentano form and a dot form of the illusion for 5 trials at 30-sec intervals. The initial illusion magnitudes for the Brentano form showed the usual decrease with age; however, the age trend for the dot form was considerably weaker. For both configurations, the initial age trends completely disappeared over the 2.5-min testing session. (34 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
