Carpentered world hypothesis

The idea of carpentered environments that is environments which are man made rather than natural environments was first developed in a paper by Segall, Campbell and Herskovitz. They suggested that the cultural differences they identified in response to Muller-Lyer stimuli were due to some subjects being raised in environments with the angles and perspectives typical of constructed housing.

As it turned out subsequent research suggested the diferences were due to retinal pigmentation but the idea has still some currency(cn).
