Learning
2
What is learning? Change in an organism behavior due to experience
3
Classical Conditioning Automatic or Voluntary Automatic: Triggered Automatically Classical Conditioning Voluntary: Behavior by choice Operant Conditioning This can be confusing: Nail Biting
4
Classical Conditioning Unconditioned Stimulus Unlearned automatic behavior What is an example? Conditioning (acquisition) Conditional stimulus: The trigger Stimulus + example behavior = UCR (unconditioned response) Conditioned reflex Conditioned stimulus= Conditioned Response
5
It’s Time For A Little Experiment! I need two volunteers
6
Operant Conditioning Learning in which behavior is strengthened if followed by a reinforcer and diminished if followed by a punisher Example: https://www.youtube.com/watch?v=Mt4N9GSBoMI&list=FLl GQzyR4L6HusOKosi8AnlQ&index=2 https://www.youtube.com/watch?v=Mt4N9GSBoMI&list=FLl GQzyR4L6HusOKosi8AnlQ&index=2

Operant Conditioning What major figure is known for his work on operant conditioning? Lets hear it from the man himself! https://www.youtube.com/watch?v=I_ctJqjlrHA&index=3&list=F LlGQzyR4L6HusOKosi8AnlQ

Operant Conditioning What kind of reinforcement is it? Two question you should ask yourself: 1.Did you see a decrease or increase in behavior? Increase=reinforcement Decrease = Punishment 2.What action was involved in delivering the consequence? Giving= positive Taking away=negative

Three Amigos Review Game Rules This is an individual game not a team event You may use your notes and/or your book If you know the answer you must http://www.imdb.com/video/hulu/vi1479016473/ For each correct answer you receive on point

Operant Learning Reinforcement Schedules 1.Continuous reinforcement schedules The desired response is reinforced every time it occurs Continuous reinforcement does not happen often What are some examples? 2.Partial (Intermittent) reinforcement Responses are sometimes reinforced Much more common than continuous What are some examples?
12
Operant Conditioning The 4 schedules of partial reinforcement Fixed-ratio schedule Reinforce behavior after a set amount of responses
13
Operant Conditioning Variable-ratio schedules Provide reinforces after an unpredictable number of responses
14
Operant Conditioning Fixed-interval schedules Reinforcement provided for the first response after a fixed time period
15
Operant Conditioning Variable-interval schedules Reinforced after first response after varying time intervals
