Effect of rectangle length on velocity thresholds for real movement.
New data are reported on the influence of size on the velocity threshold for real movement. As the length of a narrow stimulus object increases, width remaining constant, the velocity threshold also increases. These findings are discussed in relation to some psychophysical experiments on contrast and some physiological experiments on motion.
