Pavlovian conditioning
Classical conditioning
Occurs when a neutral stimulus, with a previously meaningful stimulus, eventually take on some meaning itself
Ivan Pavlov
First described classical conditioning
Reflexes in dogs
Conditioning equals
Learning
Unconditioned response equals
Unlearned response
Conditioned stimulus
initially neutral stimuli, in our example, the light
Fish example
Unconditioned stimulus
The initially meaningful stimulus
In our example the food
Unconditioned response
Naturally occurring response
Swimming to the top of the tank
Conditioned response
Response to the conditioned stimulus after conditioning
Swimming to the top for food because of the light
Forward conditioning
In which the conditioned stimulus is presented before the unconditioned stimulus
Delay conditioning
In which the conditioned stimulus is present until the unconditioned stimulus begins
Trace conditioning
This conditioned stimulus is removed sometime before the unconditioned stimulus is presented
The conditioned stimulus or neutral stimulus should
Come before the unconditioned stimulus
John Watson and Rosalie Rayner
Demonstrated classical conditioning with the child known now as little Albert
Generalization
Discrimination
If Albert could distinguish among similar but distinct stimuli
Acquisition
Takes place when the pairing of the natural and neutral stimuli (the loud noise and the rat) have occurred with enough frequency that the neutral stimulus alone will elicit the conditional response (cringing and crying)
Spontaneous recovery
The original response disappears on it’s on, but then is elicited again by the previous condition stimulus at a later time
Occurs when the conditioned response reappears quickly but less strongly after the subject has been reexposed to the pairing of the original neutral stimulus and unconditioned stimulus
No retraining
Second order conditioning
A previous conditioned stimulus it now used as the unconditioned stimulus
New CS equals town eyes new US equals light
Contiguity approach
Watson and Pavlov
Believed that the pairing of the neutral (eventual CS) and the natural (unconditioned stimulus) stimuli
occurred because they are paired in time
Contingency approach
Robert Rescorla believe that day conditioned stimulus and the unconditioned stimulus get paired because the conditioned stimulus comes to predict the unconditioned stimulus
The fish come to expect food upon seeing the light
Demonstrated this effect through blocking, where natural stimulus was paired with two neutral stimuli and only one neutral stimulus elicited the conditioned response while the other did not, as it did not predict the unconditioned stimulus
Operant conditioning or instrumental conditioning
Involves an organism’s learning to make a response in order to obtain a reward
The response is an action not typically associated with obtaining a particular reward
First discovered by Edward L Thornedike
BF Skinner pioneered the study
