PS262 Lecture Notes - Lecture 1: Sensory Cue, Psychophysics, Neuroimaging
Document Summary
Indicates that state of some property in the world: ex. recognize who someone is (auditory, visual, smell, etc. , friend in crowd, wearing pink vs. hear voice, perceptual system uses a variety of cues. Integrate all sensory info together and with info from memory: s(cid:272)ie(cid:374)tists (cid:272)a(cid:374)(cid:859)t always figure out which cues, in a complex scene, our perceptions are based on. Involves many sciences: physics (ex. hearing = how sound waves travel, anatomy/physiology (nervous system, psychology. Info/computer science: the study of perception has allowed psych to grow from its philosophical roots into an experimental science, but deep philosophical questions remain, 3 methods (different levels of analysis, physiological, psychophysical, cognitive. If a certain part of brain is damaged and particular ability disappears, then that part of brain is normally involved in this particular activity: ex. Difference threshold: barely detectable difference in stimuli experienced, ex.
