The structure of spatial ability items: a faceted analysis.
800 individuals were given a battery of 8 spatial tests which had been assembled with the aid of a mapping sentence of four content facets: rule type, dimensionality, presence or absence of rotation, and test format. An intercorrelation matrix of 49 items from these tests was analyzed by Smallest Space Analysis, SSA-I. All three facets formed distinct regions in a two-dimensional projection of a three-dimensional space. It is suggested that further facets be hypothesized to elaborate on the structure of spatial abilities.
