PSYCH 202 1st Edition Lecture 17 Biopsych-Somatosensory Cortex-Broca’s Area-Language Production/Speaking-Frontal lobe-Able to speak-If not working, can't make articulate remarks-Wernicke’s Area -Language Reception/Understanding-Temporal lobe-Take in the language we are hearing, make coherent sense of it, understand it, translate it into a meaning we can use-Auditory/”musical” Cortex-Temporal lobe-Visual Cortex-Occipital lobeoInitial stages of visual perception-Sensation comes from perceptionThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.oThe experience of sight is entirely associated in this part of brain, not from eyes at all, back of brain-Integration of Brain Areas in Complex Functioning: Example of Language Processing -Speaking a written word involves at least 5 neocortical areas-Each area performs certain functions-The areas coordinate their actions-The brain acts as an integrated system-Occipital lobe is where we first gather information, but it isn't the part that understands the information-Visual area -> angular gyrus -> Wernicke's area -> Broca's area -> motor cortexoVisual cortex: receives written words as visual stimulationoAngular gyrus: transforms visual representations into auditory codeoWernicke's area: interprets auditory codeoBroca's area: controls speech muscles via the motor cortexoMotor cortex: word is pronounced-Back of frontal lobe-Larson’s Parody of William Penfields’ Pioneering Research-Cartoon-Poking random part of brain, patient's leg goes up-Split Brain Video Clip-Joe has motor epilepsy-Left side of visual field hits right side of eyeball and vice versa-If information is on right side of brain, he can't draw it with his right hand-When information is presented to left side, it goes to right side which specializes in faces, holes, larger stuf-Left side: details, separation of elements, looking at smaller bits, language-Touch and Brain Development Video-What is the IV?: massaged or not-What are the Three DV’s in Tifany Field’s Experiment:1. Cognitive development advantage2. Weight advantage3. Attentional advantage-Note how this is a “Repeated Measures” Experiment:-Measured the same thing at 2 diferent occasionsoDischarge and 8 months later (advantage still there) Massaged: more alert, gained more weight, cognitive developmentTouching stimulates growth hormone, didn't know that at the timeEnvironment is so important: develops growth and motor coordinationAttention
