Individual differences in verbal/analytic and nonverbal/holistic cognitive strategies were studied in relationship to performance levels in spatial tasks, sex and handedness. Analytic processes are described as sequential, resulting in decomposition of stimulus information, and holistic processes, as parallel, involving information synthesis. Sixty-five undergraduates were given two spatial ability tests and a 55 item Spatial Strategy Questionnaire (SSQ) developed using theoretical hypotheses and previous research in holistic and analytic cognitive processing. Males scored significantly higher than females on one spatial test, but not other sex or handedness effects were found. High spatial performance was found to be significantly related to holistic processing, especially in the perception of test stimuli as three dimensional objects. Three dependent scoring measures calculated from the SSQ responses are discussed in the analysis of the hypothesized relationship between holistic processing and spatial ability. (Author/CM)
