Document Summary

Perception: sensation passive process of bringing information from the outside world into the body to the brain, perception active process of selecting, organizing, and interpreting that information by the senses. Sensing light/reflections with eyes, perception of objects in 3d at a variety of distances with many colours and textures: hearing/ audition. Sensing vibrations in air with ears: taste / gustation. Chemical sense (chemicals binding to specialized receptors) sensing with taste buds: smell / olfactory. Sense of smell (chemical sense: somatosenses (bodily senses) Proprioception/kinesthesis (sense of position, movement of limbs) Vestibular (sense of balance: sense of taste and smell work in similar ways and work together/in combination for perception (taste is both olfactory and gustation) Doctrine of specific nerve endings (muller: all sensory receptors are uniquely sensitive to particular energy (eyes light, but. Phosphenes: sparkly bursts of light when you push on your eyelid, mechanical pressure is registered by receptor cells in the eye as light, not touch.
