L01 L02 L03 L04 L05 L06 Analyze the components of a classical conditioning experiment, identifying the unconditioned stimulus, conditioned stimulus, unconditioned response, and conditioned response. Evaluate whether a classical conditioning scenario has the features needed to produce acquisition of a conditioned response, extinction, spontaneous recovery, conditioned inhibition, generalization versus discrimination, and/or latent inhibition.

Generalization vs. Discrimination of Conditioned Stimuli Why does your pet only run to the door when it hears your car, not other cars? This is a problem of generalization versus discrimination.

L01 L02 Differentiate operant conditioning from classical conditioning and implement operant conditioning principles in real-life learning scenarios (e.g., training a pet or child). L03 L04 L05 L06 L07 L08 Compare and contrast positive reinforcement, negative reinforcement, positive punishment, and negative punishment in terms of learning process and effects on behavior. Analyze the ways in which animals’ evolved instincts appeared to constrain learning in some studies of classical and operant conditioning (e.g., Garcia & Koelling, 1966; Breland & Breland, 1961). 4 4/15/15 Twiggy, the Waterskiing Squirrel © Timothy A.

Is the child more or less likely to scream in the next boring store? More likely, because screaming was rewarded before.
