Intra-cultural differences in the perception of visual illusions: an urban/rural comparison.

Urban and rural college students, men and women (n equal to 6 each, N equal to 24), were compared (2 x 2) on six geometric illusions using materials and procedures of Herskovits, Campbell, and Segall (1969). As expected, no significant differences in susceptibility were found for the Müller-Lyer, Sander parallelogram, or Poggendorf illusions. Rural subjects proved more susceptible to the perspective illusion; however, the urban group was more susceptible to the L-form of the horizontal-vertical illusion, but not to the T-form.
