Motor Imagery - Simulation and Understanding Mental States

Simulation and Understanding Mental States

Motor imagery is close to the notion of simulation used in cognitive and social neuroscience to account for different processes. An individual who is engaging in simulation may replay her own past experience in order to extract from it pleasurable, motivational or strictly informational properties. Such a view was clearly described by the Swedish physiologist Hesslow. For this author, the simulation hypothesis states that thinking consists of simulated interaction with the environment, and rests on the following three core assumptions: (1) Simulation of actions: we can activate motor structures of the brain in a way that resembles activity during a normal action but does not cause any overt movement; (2) Simulation of perception: imagining perceiving something is essentially the same as actually perceiving it, only the perceptual activity is generated by the brain itself rather than by external stimuli; (3) Anticipation: there exist associative mechanisms that enable both behavioral and perceptual activity to elicit other perceptual activity in the sensory areas of the brain. Most importantly, a simulated action can elicit perceptual activity that resembles the activity that would have occurred if the action had actually been performed.

Mental simulation may also be a representational tool to understand the self and others. Philosophy of mind and developmental psychology also draw on simulation to explain our capacity to mentalize, i.e., to understand mental states (intentions, desires, feelings, and beliefs) of others (aka theory of mind). In this context, the basic idea of simulation is that the attributor attempts to mimic the mental activity of the target by using her own psychological resources. In order to understand the mental state of another when observing the other acting, the individual imagines herself/himself performing the same action, a covert simulation that does not lead to an overt behavior. One critical aspect of the simulation theory of mind is the idea that in trying to impute mental states to others, an attributor has to set aside her own current mental states, and substitutes those of the target.

Famous quotes containing the words simulation, mental and/or states:

    Life, as the most ancient of all metaphors insists, is a journey; and the travel book, in its deceptive simulation of the journey’s fits and starts, rehearses life’s own fragmentation. More even than the novel, it embraces the contingency of things.
    Jonathan Raban (b. 1942)

    Such writing is a sort of mental masturbation.... I don’t mean that he is indecent but viciously soliciting his own ideas into a state which is neither poetry nor anything else but a Bedlam vision produced by raw pork and opium.
    George Gordon Noel Byron (1788–1824)

    It may be said that the elegant Swann’s simplicity was but another, more refined form of vanity and that, like other Israelites, my parents’ old friend could present, one by one, the succession of states through which had passed his race, from the most naive snobbishness to the worst coarseness to the finest politeness.
    Marcel Proust (1871–1922)
