title: Erikson's concept of inner space: a data-based reevaluation.
abstract: An analytical critique is presented of Erikson's theory that physical differences between the sexes produce differences in spatial organization, and of the experiment cited in support of that theory. Results of a new experiment are reported, which run counter to the original findings and suggest that the theory of "inner space" be reevaluated.
