ABSTRACT
The psychological study of overt behaviour is, substantially, the study of movement. But even if you were just imagining movements, you would be activating many of the same brain regions that become active during actual movement (Roland, 1993). For all of your waking lives, “behaviour” is fundamentally and inextricably linked to action, whether of discrete muscles in our mouth and throat to bring about spoken language, or of massive muscle systems in our trunk and limbs giving rise to the movements required to approach and then hit a tennis ball.
