Biological motion. First devised by Gunner Johansson in 1973, these point-light animations depict complex human actions with only a handful of motion tokens strategically placed on the body and limbs (Ahlstrom, Blake & Ahlstrom, 1997). We use these animations for psychophysical (Grossman & Blake, 1999) and fMRI studies (Grossman, Donnelly, Price, Morgan, Pickens, Neighbor & Blake, in press, Journal of Cognitive Neuroscience).
