PS262 Chapter Notes - Chapter 8: Illusory Motion, Fritz Heider, Akinetopsia
Document Summary
Motion attracts attention: movement plays an important role in animal survival- motion attracts attention, e. g. , you are looking for your friend in a large crowd at a stadium. Life without motion perception: akinetopsia (cid:894)(cid:862)(cid:373)otio(cid:374) (cid:271)li(cid:374)d(cid:374)ess(cid:863)(cid:895) a condition in which damage to an area of the cortex involved in motion perception causes blindness to motion- motion is either very difficult or impossible to perceive. When do we perceive motion: perceive motion when something moves across our field of view, actual motion of an object is called real motion (e. g. , perceiving a car driving by) Ps262: week 5: perception of motion can also be produced by stimuli that are not moving. Induced motion occurs when motion of one object (usually a large one) causes a nearby stationary object (usually smaller) to appear to move (e. g. , the moon usually appears stationary in the sky. Jere(cid:373)(cid:455) (cid:449)alks past maria; maria"s e(cid:455)es are stationary (creates local disturbance in optic array)
