Document Summary

Sensation: transformation of chemical, mechanical, light and sound energy (of the world) into electrical activity in the brain. Process by which sensory systems gather info about the environment. We sense so we can perceive so we can act. Cognitive impenetrability: doing things with no conscious response. Perception: psychological processes involved in organization and interpretation of sensations. Extracting meaning from what is sensed tying it to what is known, understood. Most is multisensory (more than one sense) Vision: sensing with eyes (perception of objects in 3-d) seeing. Gustation: sensing with taste buds tasting. Somatosenses: bodily senses (skin senses-touch, pain, temp, kinaesthetic senses- Gustation and olfaction = chemical senses position of limbs, pleasurable senses, vestibular senses- sense of balance, acceleration) Sensory organs respond to a very restricted range of energy. Receptor cells: specialized neurons that convert physical energy into electrical signals. Sensory quality experienced depends on nerve stimulated (not how its stimulated)
