A study of orientation errors in response to Kohs‐type figures (1)

In order to elucidate the nature of the orientation errors encountered when subjects are required to reproduce Kohs‐type figures, subjects drawn from a culture where such errors are reported to be relatively common were required to reproduce orientation of simple figures. It was found that the responses made in the case of square figures showed a definite drift towards a “stable” orientation; the drift observed in the case of circular stimuli was too weak to permit an unambiguous interpretation. The relevance of these data to previous data on cross‐cultural differences in responses to Kohs‐type stimuli is briefly examined.
