Document Summary
Psychology (8 t h edition) by gleitman, gross, & reisberg: signal detection theory deals with the complexity of decision criteria; suggests that a perceiving a stimulus is a judgement about a momentary sensory experience, payoff matrix a pattern of benefits & costs associated with certain types of responses. A survey of the senses: all of our senses follow similar steps, transduction the process through which a physical stimulus is converted into a neural signal, sensory coding how qualities of sensory inputs are translated into specific representations within the nervous system, one aspect of coding is psychological intensity. When they hit the ear, it triggers the auditory receptors: amplitude the height of a wave; indicates the amount of pressure exerted by each air particle, frequency crests per second, when amplitude goes up, the loudness goes up; when frequency goes up, the pitch goes up, sound is measured in decibels, sine waves = ingredients for complicated sounds.
