GradeBuddy is best used as a supplement to your own notes, not as a substitute.o Careful observations (e.g. of the effects of brain injuries, experiments, et cetera) strengthened the materialistic perspectiveo “The mind is what the brain does”Hemi-Neglect (aka unilateral neglect): - “Whose hand is this?”- Guys shaves only right side of himself, cant spontaneously direct attention to the left side of their reality (vision, or physical), can’t draw daisy petals on left side Blindsight: - “No, I don’t see that stick you’re pointing at me over there on my right.”- Brain injury (fall), lessoning of visual cortex, not aware that they went around the chair- Absolutely blind, but can still navigate space- Vision involves more than just the occipital lobeSplit-Brain: - The right brain might know the answer, but it’s keeping the whole thing hush-hush.- Severe corpus callosum, video in class “Joe”o Flash picture to right of dot, goes to left of braino Pic to the left of dot, goes to disconnected right half of the brain; pick up pen and draw (can draw it with left hand), went to right side of brain Brief History of Physiological Psychology -5th Century BCo Hippocrates: Controls sensations and perceptions, thoughts, emotions, morality and behaviors. Contemporary, “physician,” supports idea that role of brain is seat of our emotionso Aristotle: It keeps the “passions of the heart” in check by cooling the blood! Brain is the radiator of blood-The 2nd Century A.D.o Galen: Physician (to the gladiators) who subscribed to Hippocrates’ view, and extends it by adding evidence that traumatic brain injury often causes problems of sensation, perception, thinking and reasoning. Galen calls Aristotle’s understanding of the brain’s function “utterly absurd.” Why are all of the sensory nerves connected to the brain instead of to theheart?-17th Centuryo Descartes: French Philosopher and Mathematician Descartes: ‘I think therefore I am” I know I exist because I’m having experiences, you I’m not so sure about Says the universe was “wound up” by God but has since obeyed purely physical laws.
