Where is it going?Module 19: Motion Perception

Motion PerceptionNeural pathways in the brain combine information about: eye-muscle activitythe changing retinal imagethe contrast of the moving object to the stationary background. Brain views LARGER objects as moving more SLOWLY than smaller objects Brain assumes: - shrinking objects are retreating - ENLARGING objects are APPROACHING.

Stroboscopic MotionThe illusion of motion by the rapid projection of slightly changing imagesThe concept a motion picture (movie) or stop motion animation uses.See how HERE (3 min)

Phi PhenomenonThe illusion of motion when fixed lights are turned on and off in a sequence (See Brain Games clip)Stare at the X in the middle and notice what happens. Is the Green Dot Moving?

Are the wheels and smoke moving?Induced MotionKarl Duncker studied this with the dot and moving rectangle. Rectangle moved but people thought it was the dot moving. This because of top-down processing (people expected the dot to move) and our assumption that the background is stationary.

The eagle is stationary, the background is what is moving.

Notice how the background is only thing moving

Spiral Motion DetectorsResearch shows that different neural pathways in the cerebral cortex process information about the depth of objects, movement, form, and color. As you view the spiral motion your spiral motion feature receptors are being used. When you look at a stationary object, the receptors for that motion stop but their opposite turn on for a brief time causing the illusion.

Spiral MotionStare at the spiral and then look at someones head afterwards.What Happens?

Motion BlindnessLook steadily at the green dot in the middle. Dont blink as blinks and sudden eye movements destroy the illusion. Notice that one, two or all of the white discs will disappear and reappear. Deals with your selective attention
