Slide 1:Learning
Slide 2:Learning - A relatively permanent change in behavior due to experience. Thorndike, Pavlov, Watson, & Skinner:
Learning Theorists Behaviorism
Slide 3:Edward L. Thorndike (1874-1949)-
-trial & error learning
Slide 4:Law of Effect (1927) “Actions which lead to a satisfying state of affairs are likely to be repeated.”
Slide 5:B.F. Skinner (1904-1990)-
Stimulus-Response contingency
Operant Conditioning
Slide 6:Human
Learning Operant Conditioning Theory of learning that says the consequences of behavior lead to changes in the probability of its future occurrence (B.F. Skinner). Reinforcers Punishers
Slide 7:Human
Learning Increases the probability of a behavior occurring by receiving a pleasant stimulus. Positive Reinforcers
Slide 8:Human
Learning Negative Reinforcers Increases the probability of a behavior occurring by taking away a negative stimulus.
Slide 9:Human
Learning Positive Punishers Decreases the probability of a behavior occurring by receiving a negative stimulus. You have extra chores!
Slide 10:Human
Learning Negative Punishers Decreases the probability of a behavior occurring by removing a positive stimulus.
Slide 11:Human
Learning Using Reinforcers & Punishers
Slide 13:Reinforcers or Punishers? Jodi: "Treat collar - When the dog doessomething good, a treat comes out of it's collar.“ Jessica: "Play bad music and when he does something good you take it away." Audrey: "Purchase a hand held remote whichhurts the dog's ears. When he bites you, you push it!“ Liz: "Water tray with lid that covers water when misbehaving."
Slide 14:Human
Learning Principle of time interval - learning is optimal if the time interval between stimuli and responses is brief. Associated Principles
Slide 15:Human
Learning Associated Principles Shaping and Chaining - rewarding successively closer responses to the actual desired behavior.
Slide 16:Fixed-Ratio (FR) – a specific number of behaviors are required before you are rewarded. Reinforcement Schedules: Ratio Schedules
Slide 17:Reinforcement Schedules: Ratio Schedules Variable-Ratio (VR) - the behavior must be made on average around a certain number that is free to vary. 2nd base? # Dates
Slide 18:Reinforcement Schedules: Interval Schedules Fixed Interval (FI) – a specific amount of time must elapse before you are rewarded.
Slide 19:Reinforcement Schedules: Interval Schedules Variable-Interval (VI) – a non-standard amount of time (which varies around some avg, however) must elapse before you are rewarded. Pop Quiz!
Slide 21:Classical Conditioning
Slide 22:I. Pavlov - New behaviors occur due pairing with already learned S-R in a short time frame. Classical Conditioning
Slide 23:Human
Learning Principles of Classical Conditioning
Slide 24:The Original Pavlovian Classical Conditioning Experiment
Slide 25:Unconditioned Stimulus (UCS) - a stimulus associated with an initial response. Principles of Classical Conditioning
Slide 26:Unconditioned Response (UCR) - a response associated with an initial UCS. Principles of Classical Conditioning
Slide 27:Conditioned Stimulus (CS) - a stimulus due to learning elicits a similar response to a UCS. Principles of Classical Conditioning
Slide 28:Conditioned Response (CR) - a learned response following a CS. Principles of Classical Conditioning
Slide 29:Human
Learning Principles of Classical Conditioning
Real World Pairings :Real World Pairings
Development of Phobias :Development of Phobias
Slide 33:Human
Learning Principles of Classical Conditioning
Slide 35:Human
Learning Stimulus Discrimination –not responding to non-CS including those which are similar to the CS. Conditioning Principles
Slide 36:Human
Learning Stimulus Generalization –responding to non-CS including those which are similar to the CS. Conditioning Principles
Slide 37:Conditioning Principles Extinction – lack of reinforcement of the CR, leading to its decline.
Slide 38:Human
Learning Observational Learning Learning - by watching others
Slide 39:Human
Learning Bandura’s Cognitive Theory of Observational Learning People observe the behavior of others to gain knowledge about the kinds of things people do.
Slide 41:Bandura’s Cognitive Theory of Observational Learning Four interacting mental processes occur:
Slide 42:Bandura’s Cognitive Theory of Observational Learning Attention - Perceiving the model and find it interesting Four interacting mental processes occur: Memory - Encode info for later use Motor control- Memory guide actions Motivation - Reason to perform actions
