CARL GABBARD DIALA AMMAR LUIS RODRIGUES Department of Health and Kinesiology Texas A&M University College Station, Texas, USA The study of motor imagery affords an attractive approach in the quest to identify the specific aspects of cognitive and neuromotor mechanisms and rela- tionship involved in action processing. Here, the authors investigated the re- cently reported finding that compared to the left-hemisphere, the right brain is at a significant disadvantage for mentally simulating reaching movements. The authors investigated this observation with strong right-handers that were asked to estimate the imagined reachability of visual targets (presented at 150 ms) at multiple points at midline, right- and left visual field; responses were compared to actual maximum reaching distance. Results indicated that individuals are relatively accurate at imagined reachability, with no significant distinction be- tween visual field responses. Therefore, these data provide no evidence to sup- port the claim that the right hemisphere is significantly inferior to the left hemisphere in estimations of motor imagery for reaching. The authors do ac- knowledge differences in the experimental task and subject characteristics com- pared to earlier work using split-brain and stroke patients.
