Document Summary
4. 1 sensation and perception at a glance. The process of detecting & then translating the complexity of the world into meaningful experiences occurs in 2 stages: sensation: the process of detecting external events by sense of organs and turning those stimuli into neural signals. Perception: involves attending to, organizing and interpreting stimuli that we sense: transduction: when specialized receptors transform the physical energy of the outside world into neural impulses. Sensory receptors involved in transduction are different for the different sense. Pressure, stretching, or piercing of the skin surface. Chemicals on the tongue and in the mouth. Light-sensitive structures at the back of the eye. Hair cells that respond to pressure changes in the ear. Different types of nerve endings that respond to pressure, temperature changes, and pain. Cells lining the taste buds of the tongue. Chemicals contacting mucus- lined membranes of the nose. Nerve endings that respond selectively to different compounds.
