摘要: Changes in magnitude of Muller-Lyer illusion as a function age were studied 48 hyperactive and nonhyperactive boys. As expected, decreasing linear trend was found with increasing from 6 to 9 years for For boys, increased 7 then decreased. Differences hyperactives resembled Piaget's hypothesized developmental curve primary moved forward years, supporting the notion lag rather than an aberrancy perceptual development. Peak 6-year-old non-hyperactives 7-year-old hyperactives. By ages 8 9, no significant differences between two groups.
