Abstract:

Segall, Campbell and Herskovits 1963, 1966 put forward the view that the Muller-Lyer illusion is a function of rectangularity in the environment, and that the horizontal-vertical one depends on openness of terrain. Existing contrasts in these two variables in Ghana were used in an attempt to investigate the hypotheses. A total of 213 illiterate subjects were tested, and 41 subjects in Britain. A significant overall difference in the expected direction between Ghanaian and British subjects was obtained with the Muller-Lyer, but no differences corresponding to environmental variations emerged on either of the illusions within the subgroups of Ghanaian subjects. The reasons for this partial failure to replicate are examined in the light of other studies, and some theoretical implications discussed. Author
