Assessed 13- and 20-week-olds infants' discrimination between shearing stimuli, in which columns of dots move vertically on a screen at different velocities, and foil stimuli, in which all dots move at the same velocity. Results revealed the threshold levels of dot velocity in shearing stimuli at which discrimination occurred. (BC)
