METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Brain & Neurons
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING The Brain • Mechanist view of behavior • Kinesis, taxis, reflex • The Neuron and Action Potential • Cephalization
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Braightenberg’s Vehicles
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING The Brain: Organizing Principles • Localization of Function • Phineas Gage • Wernike’s aphasia and Broca’s Aphasia • Topographic Projection • All or none law
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Motivation
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Maslow’s Hierarchy • We need to satisfy lower level needs before progressing • Exhibits partial priority ordering • Arguable
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Basic Model of Motivation • Drive: To take care of biological self • Dual Output Regulation (Canon and Bernard) • A variable environment vs. constant environment • Where did our ancestors come from?
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Negative Feedback Loop • Input, regulator, set point, output
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Autonomous Nervous System • Sympathetic: • Arousal • Emergency response • Parasympathetic: • Long term energy storage
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING The Psychological and Physiological Aspects • Two consequences: • H for HOMEOSTASIS and HYPOTHALAMUS • Know Examples! • Thirst • Cold • Hunger • Next Slide
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Hunger • Two parts of the Hypothalamus: • Lateral – Senses hunger • Ventromedial – Senses fullness • Fat cell Hypothesis • Fat cells established during infancy • Releases: • Leptin– to indicate fullness • NPY – to indicate hunger/appetite
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Hunger (cont.) • Glucose/Glycogen • Glucose Glycogen – for storage when full • Glycogen Glucose – for fuel when hungry • Some animals have “fuel tank indicators”
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Hunger (still cont.) • Externality Hypothesis (Schacter) • Some people are more sensitive to bodily cues • Obese people are less sensitive than non-obese • Liquid diet exp., Yom Kipper fasting study • Restrained vs. Nonrestrained eaters • Restrained will intake much more upon breaking
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Yerkes Dodson Law • There is this “best” level of arousal for performance (too low/high reduces it) • High arousal levels = higher performance if… • The task becomes easier • You are more experienced • Presence of observers • Think roaches
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Need for Achievement • Another higher level motivation • TAT projective tests • People vary their levels of motivation to complete a task • Motive is relative to the goals they set themselves
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Emotions • James-Lange Theory • Relation between the stimulating event, bodily arousal, and perceived emotion • “All emotion is derived from the presence of a stimulus, which evokes a physiological response” • Wikepedia <3
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Emotions (cont.) • Schacter Singer Experiment • Model of emotional experience based on cognitive labels in response to physiological excitation
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING Learning
METHODOLOGY SLEEPING & DREAMING BRAIN & NEURONS MOTIVATION LEARNING • Pavlov's classical conditioning • Thorndike's law of effect and Skinner's operant conditioning • Evaluation of behaviorism • Other perspectives

PERCEPTION ATTENTION MEMORY PROBLEM SOLVING Perception
PERCEPTION ATTENTION MEMORY PROBLEM SOLVING Perception: Audition • 20-20,000 Hz = normal range • Most speech sounds occur in central range (most sensitive) • Transduction from physical signal neural signal occurs at basilar membrane • Frequency (Volley) theory: frequency of the AP tells the actual frequency in the real world (problem: AP can only fire ~ 1000 times/sec.) • Place theory: location of the depolarizing hair cells on the basilar membrane tells the frequency of the sound in the real world
PERCEPTION ATTENTION MEMORY PROBLEM SOLVING Vision • Duplex theory of vision: rods vs. cones in retina • Very wide intensity range • Lateral inhibition (originally studied with Limulus, the horseshoe crab) • Feature detectors (bottom up): frog and cat examples • Simple cortical cells respond to bars of light (or darkness) surrounded by darkness (or light) in a particular orientation • They seem to be made up of a line of circularly oriented retinal ganglion cells connecting to a brain cell
PERCEPTION ATTENTION MEMORY PROBLEM SOLVING Top Down vs. Bottom Up Processing • Top down using information that you already know and having it help you interpret new information…just like finishing someone else's sentences…coming at with assumptions • Bottom upstartwith what you actually see…take in sensory information and then make perceptions
Late Selection PERCEPTIONATTENTION MEMORY PROBLEM SOLVING Attention as a Bottleneck Early Selection Cocktail Party Effect Filter Theory (in class demo, gorilla movie) Attenuation Theory* (in class demo) Late Selection Theory (pennies at the bank) Spotlight Theory of Attention
