Online corrections can occur within movement imagery: An investigation of the motor-cognitive model

Hum Mov Sci. 2024 May 1;95:103222. doi: 10.1016/j.humov.2024.103222. Online ahead of print.ABSTRACTThe motor-cognitive model proposes that movement imagery additionally requires conscious monitoring owing to an absence of veridical online sensory feedback. Therefore, it is predicted that there would be a comparatively limited ability for individuals to update or correct movement imagery as they could within execution. To investigate, participants executed and imagined target-directed aiming movements featuring either an unexpected target perturbation (Exp. 1) or removal of visual sensory feedback (Exp. 2). The results of both experiments indicated that the time-course of executed and imagined movements was equally influenced by each of these online visual manipulations. Thus, contrary to some of the tenets of the motor-cognitive model, movement imagery holds the capacity to interpolate online corrections despite the absence of veridical sensory feedback. The further theoretical implications of these findings are discussed.PMID:38696913 | DOI:10.1016/j.humov.2024.103222
