Document Summary
Sensation- translating information from outside the nervous system into neural activity: 5 senses (touch, sight, hear, taste, smell) Perception- process through which sensations are interpreted: how we give meaning to what we have sensed. Basic steprs of sensing: accessory structures modify the stimulus, pinna (the ear) move it to hear, transduction- converts energy to neural activity, sensory nerve carry information to the brain. Doctrine of specific nerve energy- when you press your eyes when closed and see light it is pressure that causes the photo receptors to fire: brain processes the information. Smell goes to the olfactory bulb in the brain: adaptation- occurs when the stimulus does not change. Wavelength- distance from one peak to the next. Frequency- number of cycles (waves) per second. Timbre- the quality of sound. (the signature of an instrument) Auditory accessory structure: pinna- outer ear.
