Document Summary

Your experience of the world depends on the physical stimuli you encounter (sensation) and your processing of that stimuli (perception) Participants believed that the fake hand was their real hand and that they could feel things in the fake hand. 30% of the brain is devoted to sight. One reason: humans rely heavily on sight. Much of our sensation & subsequent perception starts with visual cues. The physiological stimulation of your sense organ= sensation. Lens: transparent, inverts image and refracts the image to hit the retina. Retina: neural lining in back of the eye, image hits it upside down, sends information onto the brain. There are cases where the brain does not organize inverted retinal images, causing a person to experience the world upside down. Charles bonnet syndrome- hallucinations due to malfunctions in brain imaging and processing. George stratton: pioneered the study of perception in vision by wearing special glasses which inverted images up and down and left and right.
