Imagery

(see also Hallucination)

It has been suggested that self-report questionnaires measure “explicit” visual imagery, a form of imagery that is consciously experienced and is phenomenal in nature, often having a content that evokes personal feeling and meaning in the imagery [90, 102]. An example of a definition of this kind of imagery is: All those quasi-sensory or quasi-perceptual experiences of which we are self consciously aware, and which exist for us in the absence of those stimulus conditions that are known to produce their genuine sensory or perceptual counterparts [90, p. 15]. Objective measures have been described as measuring “implicit” visual imagery, a non-phenomenal kind of imagery that can be employed without awareness to solve certain tasks [90, 102]. An example of a definition of implicit visual imagery is: A memory code or associative metaphor that provides spatially parallel information that can mediate overt responses without neces

MEASURING VISUAL IMAGERY ABILITY: A REVIEW*

It was recently proposed that the lack of relationship between subjective and objective measures of imagery was due to the fact that self-report questionnaires assessed object imagery while spatial tests assessed spatial imagery. In support of this argument, the Object Scale of the Object Spatial Imagery Questionnaire was found to correlate significantly with the VVIQ and a Degraded Pictures Test (chosen to assess object imagery) but not with a Mental Rotations Test or a Spatial Imagery Test and negatively with a Paper Folding Test (chosen to assess spatial imagery). The Spatial Imagery Scale correlated significantly with the Paper Folding Test, Mental Rotations Test, and Spatial Imagery Test but not with the Degraded Pictures Test. It had a significant but low correlation (r = .18) with the VVIQ [75]. It seems, then, that the Object Scale of the OSIQ correlated significantly with other tests of Object Imagery but not with tests of Spatial
