Document Summary

Psychology lecture week 8: sensation and perception: psychophysics and. Receptors: the sensitive elements that absorb light and start the electrophysiological process that sends visual signals to the brain. There are the rods and cones found in the retina (they are not evenly distributed) Sensation: the process that allows our brains to take in information via our senses, which can be experiences and interpreted by the brain. The following are the human sense: sight (vision, hearing (audition, taste (gustatory, smell (olfactory, touch (soma tenses, body awareness (proprioception, balance (vestibular) Visible spectrum: the portion of the electromagnetic spectrum that is visible to the human eye. A typical human eye will respond to wavelengths from about 390 to 700nm. Even the receptors you have are lazy and get tired) Sensory adaptation: sensory adaptation occurs when sensory receptors change their sensitivity to the stimulus. This phenomenon occurs in all senses, with the possible exception of the sense of pain.
