 There are debates, however, about what this traditional, phenomenological way of zeroing in on motor imagery as the feeling of imagining doing something entails. As it is acknowledged by all involved in this debate, not all imaginative episodes of doing something would count as motor imagery: you somehow need to imagine doing something from a first person, and not a third person perspective. Marc Jeannerod, one of the most important psychologists working on both motor imagery and mental imagery made a distinction (following the practice in sport psychology) between internal (first person) and external (third person) imagery, and only the former would count as motor imagery (the latter would be sensory imagery of me doing something, see Jeannerod 1994, p. 189).
