Validation with a French sample of the four scales of Switras's Survey of Mental Imagery.

The present study investigated the psychometric properties of the Switras questionnaire, the Survey of Mental Imagery, with a French sample of 162. Only Form A and four subtests of the questionnaire were given. The present factor analyses confirm the factorial composition observed by Switras in 1978. Three subcapacities of imagery were evaluated by these subtests: controllability, vividness, and formation in four specific modalities of imagery, namely, visual, auditory, somesthetic, and kinaesthetic.
