A Factor Analytic Study of Two Measures of Mental Imagery

To examine the factor structure of the Vividness of Movement Imagery Questionnaire and the Visual Elaboration Scale measure, in Study I the former test was given to 133 psychology students and in Study II the latter test to 147 students. Principal components factor analysis yielded one factor for the former and five factors on the latter. The Visual Elaboration Scale has such a complex factor structure that difficulties may arise in interpretation. However, the Vividness of Movement Imagery Questionnaire has a simple unitary structure.
