Document Summary
Psy280: lecture 1 notes: recognize the 6 general components of the perceptual process. Neural processing: it starts at the level of receptor. Action: action in response to stimulus, action can also profoundly change our sensation of information, make arguments in favor of perception being a valid topic of scientific investigation. Sensation and perception are the foundation for mental event. Thus, it is in the domain of psychology. It is the about mental experience: recognize the relationships between stimulus, perception and physiology, in the 3 general approaches to the study of perception. Neural recordings (for stimuli and physiology), e. g. electrodes insertion. Neural activity during psychophysics (for physiology and perception), e. g. neuroimaging: distinguish between 3 classical methods in psychophysics. Method of constant stimuli: describe the ways in which absolute threshold can be established. By the 3 classical methods in psychophysics: use psychometric functions to derive the relationships between stimulus intensity and perception.
