Classical Conditioning + Intro to Operant Conditioning Learning Unit Mrs. Craig Conditioning= Learning Means the same as Learning How do we know learning has taken place???? Learning is a permanent change in behavior Ivan Pavlov- Russian scientist 1900’s First to discover classical conditioning Experimented with dog’s digestive system Famous experiment Discovered a neutral stimulus (bell, footsteps) could be taught to dog to create salivation Normally food creates salivation. First discovery on how learning occurs Classical Conditioning Most primitive learning Starts with something that is born in the organism—UCS UCS= unconditioned (unlearned) stimulus UCR= unconditioned (unlearned) response NS= neutral stimulus (no connection to UCS) the NS becomes the CS over time CS= conditioned (learned) stimulus CR= conditioned (learned) response Pavlov’s Formula for CC UCS to UCR (food to salivation) NS + UCS to UCR (bell+food to salivation) or “learning by association” CS to CR!!! (bell to salivation) Learning has occurred!!! John B Watson Baby Albert Experiment Using classical conditioning to teach fear Generalization- fear of a general rather than a specific stimulus Discrimination- fear of a specific stimulus Experiment with Baby Albert considered unethical today. WHY?? Review of Classical Conditioning Starts with an unlearned relationship (UCS to UCR) NS paired with UCS over time Learning takes place when the CR is triggered by the CS (the original NS). Humans have very few inborn unlearned relationships sooo……very few classical conditioning learning opportunities.!!! OPERANT CONDITIONING Another form of learning Called S-R-R theory S= Stimulus R= Response R(2nd one)= Reinforcement Classical Conditioning does NOT use reinforcement at all!!!!! REINFORCEMENT ALWAYS increases a behavior happening again!!! Positive Reinforcement= praise/feels good Negative reinforcement= avoid something to increase a behavior Punishment=decrease a behavior
