Abstract
Two experiments involving mental rotation with two types of manual rotation were run. In Exp 1, participants had to perform the mental rotation task with active hand movement using a rotating device that did not move automatically. In Exp 2, participants had to perform the mental rotation with passive hand movement using an automatically rotating device. The interaction effect between mental and manual rotation was observed only in the former case. These opposing results indicate that it is motor planning associated only with active movement that plays an important role in the interaction between mental and manual rotation and not the proprioceptive/kinesthetic feedback caused by the manual rotation itself.
Highlights
Mental imagery is defined as quasi-perceptual experience such as “seeing” in the absence of the appropriate immediate sensory input (e.g., Kosslyn, Behrmann, & Jeannerod, 1995)
The results of this experiment indicate that kinesthetic feedback itself does not have any influence on the mental rotation performance
The present study investigated what part of the motor system played an important role in mental rotation, with the experiment focused on motor planning and kinesthetic feedback
Summary
Mental imagery is defined as quasi-perceptual experience such as “seeing” in the absence of the appropriate immediate sensory input (e.g., Kosslyn, Behrmann, & Jeannerod, 1995). It has been revealed that some kinds of mental imagery share mechanisms with action (e.g., Pearson, 2001; Pearson, Logie, & Gilhooly, 1999). Mental rotation of visual stimulus is a good example of such cognitive activity. It occurs when someone compares two visual stimuli (e.g., 3D cube array objects; Shepard & Metzler, 1971) whose orientations differ from each other.
