Learning
What is learning?Change in an organism behavior due to experience
Classical Conditioning
Automatic or VoluntaryAutomatic: Triggered Automatically
Classical Conditioning
Voluntary: Behavior by choiceOperant Conditioning
This can be confusing: Nail Biting
Classical Conditioning
Unconditioned Stimulus Unlearned automatic behavior
What is an example?
Conditioning (acquisition)Conditional stimulus: The trigger
Stimulus + example behavior = UCR (unconditioned response)
Conditioned reflexConditioned stimulus= Conditioned Response

I need two volunteers
Operant Conditioning
Learning in which behavior is strengthened if followed by a reinforcer and diminished if followed by a punisher

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=FLlGQzyR4L6HusOKosi8AnlQ
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
Operant Conditioning
Action Increase Decrease
Given Positive Reinforcement behavior
Positive punishment behavior
Taken away Negative Reinforcement behavior
Negative Punishment Behavior

Operant Learning
Reinforcement Schedules1. 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?
Operant Conditioning
The 4 schedules of partial reinforcement
• Fixed-ratio schedule• Reinforce behavior after a set amount of responses
Operant Conditioning
• Variable-ratio schedules• Provide reinforces after an unpredictable number of
responses
Operant Conditioning
• Fixed-interval schedules• Reinforcement provided for the first response after
a fixed time period
Operant Conditioning
• Variable-interval schedules• Reinforced after first response after varying time
intervals
