Gender Differences in the Mental Rotations Test Are Partly Explained by Response Format
Abstract
Gender differences in the Mental Rotations Test (Vandenberg & Kuse, 1978) are larger than in virtually all other spatial tests and have been highly robust over decades. Several possible explanations for this phenomenon have been proposed. This research tests the hypothesis that the gender differences are partly due to the response format of the MRT (two out of four responses correct in each item). This format, in combination with the high time pressure of the MRT, may be particularly conducive to the performance of highly confident (i.e., frequently male) participants who use “quick-and-dirty” response strategies. In study of 288 students, a new MRT version was used in which a variable number of 0 to 4 alternatives per item were correct. Gender differences were significantly smaller than in the standard MRT. In particular, the performance of highly confident male participants was markedly lower than in the standard MRT.
