Principles of Learning
2
“ Give me a dozen healthy infants, allow me to control the environment, and I can make them into anything I want.”
4
Infant with rumination d/o Treated with aversive shock therapy Your Types of Learning Classical: unavoidable, physical association Operant: learning through actions Social: learn by watching others Cognitive: thought process
5
First in learning, thus “classical” Involuntary Learning More physical in Nature Ivan Pavlov, 1900 Researched digestive system Pavlov’s Dogs
6
Terminology Classical Conditioning: method of conditioning using associations between a natural stimulus and a learned, neutral stimulus Stimulus: anything that elicits a response (natural) Response: a reaction to the stimulus Dogs: Receive food (S) Salivate (R)
7
Terminology UCS: Unconditioned Stimulus (automatically elicits a response) UCR: Unconditioned Response (a natural reaction to UCS)
8
Conditioned Stimulus: previously a neutral stimulus that has been associated with a natural stimulus *experimenter (CS) associated with food (UCS) Conditioned Response: a response to a stimulus that is brought about by learning *experimenter (CS) salivation (CR)

10
Behaviorists John Watson – Emotional Conditioning Little Albert: Loud noise (UCS) Fear (UCR) Rat (CS) + Noise (UCS) Fear (UCR) Rat (CS) Fear (CR) Stimulus generalization: stimulus that seems the same (white rat, white bunny) Extinction: Loss of association over time
11
Removal of Fear Mary Cover Jones: student who worked for Watson Associate pleasure with object of fear Helps with phobias HIGHER-ORDER CONDITIONING: responding to a second stimuli
12
Operant Conditioning: Conditioning that results from one’s actions and the consequences they cause **Behavior learned or avoided as result of consequences*** Operant v. Classical: automatic responses v. voluntary ones
13
B.F. Skinner Believed behavior result of consequences in our environment Skinner’s Box: Operant Conditioning Chamber Studied Animal behavior http://www.youtube.com/watch?v=I_ctJqjlrHA
14
Operant Conditioning Process: Learning from the consequences of his or her voluntary actions Reinforcement: Follows a response, increases chance to repeat behavior 1. Positive: Pleasant reinforcements Primary: NEEDS - Necessary for psychological/physical survival Secondary: WANTS – Comes to represent a primary reinforcer ($$$ = food, shelter, etc) 2. Negative: Something unpleasant is stopped or taken away
15
Punishment: weakening response, unpleasant consequences Generalization & Discrimination: behavior that spreads from one situation to a similar one Extinction: when behavior stops Shaping: Gradually refining response by successively reinforcing closer approximations of it Chaining: reinforcing each part of desired sequence
16
Schedule of Reinforcement: methods of reinforcing Continuous vs. Partial Variable Ratio: unknown number of desired responses before reinforcement is given. (Casino) High/Steady rate of response
17
Fixed Ratio: One reinforcement for every time desired behavior is performed High rate of response until enforcement is received Variable Interval: varying amounts of time pass between reinforcement and behavior (fishing) Steady rate of response
18
Fixed Interval: Reinforcement is received after a fixed amount of time Produces an accelerated rate of response each time reinforcement approaches Report Cards Paycheck
19
Albert Bandura Observational Learning, type of Social Learning Learning that occurs in a social situation Bo-Bo Doll Grow up watching and imitating? What could the results be? Cliques Clubs Families Culture Religion
20
Cognitive Learning: Learning based on mental processes and previous knowledge E.C. Tolman Cognitive Maps: mental image of where one is located in space Strategies: Methods for solving problems Schemas
21
Trying to learn how to learn Metacognition Synopsis in your own words Take breaks – brain works on problems while at rest
