How vision (text), audition (text) taste, smell, and touch work (textbook.) Illusions, limbs, and blind site.
* What is real? * Process of taking in – sensation through senses. Collection of environment extra * Perception- interpretation from environment. Extra * Sensation: converting the stimulus (smell, sound, ect) as it arrives at receptors in the ears, eyes, or mouth, into neural impulses. * Perception: processing, comparing, and interpreting sensory stimuli to give them meaning. Biased process. * We try and find ways to interpret info to make it make sense to us. Extra. * Our own ways change the way we take in info. Biased based on who you like better. Extra * Both work together to interpret the environment.
Synesthesia: boundaries between the senses break down. * Examples: the taste of beef, such as a steak, produces a rich blue * Guitar music brushes softly against her ankles * Buttered toast is rough, but not pointy and if it has jelly on it the rough texture is rounded
(Functional MRI) FMRI has shown that when playing MUSIC FOR INDIVIDUALS WHO report the previous phenomenon, their auditory and visual cortex become active.
Only auditory cortex becomes active for normals.
Disorder: needs to be abnormal (not normal or not common), uncommon needs dysfunction. You may not know it’s abnormal if you have always experienced it.
Blind site: damage to visual cortex, people are able to see, but are unaware of their ability. Sensation is there but perception isn’t.
Blindness: not be able to see.
Assessed with take in which individuals are asked to locate visual stimuli that they believe they cannot see. Avoid objects and not know that they are. Extra.
