a. Classical Conditioning: A type of learning where an organism comes to create associations between multiple stimuli
b. Ivan Pavlov - Discovered classical conditioning through his study of salivary reflexes with dogs
a. A stimulus that elicits a reflexive response in the absence of learning.
a. A reflexive response elicited by a stimulus in the absence of learning.
a. An initially neutral stimulus that comes to elicit a conditioned response after being associated with an unconditioned stimulus.
a. A response that is elicited by a conditioned stimulus; it occurs after the conditioned stimulus is associated with an unconditioned stimulus.
a. Temporal Contiguity Theory
i. Responses develop when the interval between UCS and CS is very short
ii. Backward conditioning?
b. Contingency Theory
i. Association was dependent upon the perceived predictability of the CS of the UCS
a. Two types of trials:
i. Format A
1. Tone à followed by SHOCK
b. Format B
i. Tone with light à followed by SHOCK
c. Randomized trials
i. A,B,B,A,A,A,B,A,B,B,B,A,etc
a. Generalization
b. Extinction
c. Spontaneous Recovery
d. Higher Order Conditioning
a. A new stimulus resembling the original elicits a response similar to CR
a. weakening of the relationship between the CR and the CS by continual presentation of the CS alone
a. CR recurring after a time delay
a. A procedure in which a neutral stimulus becomes a conditioned stimulus through association with an already established conditioned stimulus.
a. Conditioning Fear
b. Conditioned Taste Aversion
c. Learned Helplessness
a. John Watson’s experiment on 11 month old “Little Albert”
i. Each time he reached for the rat, Watson made a loud clanging noise right behind Albert
b. Little Albert’s fear generalized to just about anything white and furry
a. When an organism becomes nauseated some time after eating a certain food, which then becomes aversive to the organism
b. Original Study: John Garcia and his radiated rats
a. tendency to fail to act to escape from a situation because of a history of repeated failures
i. Classic Study
ii. Real-Life Applications
a. changes in voluntary behavior based on experienced consequences
a. Created the Law of Effect – responses followed by pleasurable consequences are repeated
a. rewarding approximations of desired behaviors
b. Skinner Box: A controlled environment for training
i. When an animal in a Skinner box presses a bar, a food pellet or drop of water is automatically released.
a. The process by which a stimulus or event strengthens or increases the probability of the response that it follows.
a. The process by which a stimulus or event weakens or reduces the probability of the response that it follows
a. Positive Reinforcement
i. addition of pleasurable stimulus to increase the behavior
b. Negative Reinforcement
i. removal, escape or avoidance of aversive stimulus to increase the behavior
a. Positive Punishment
i. addition of unpleasant stimulus to decrease the behavior
b. Negative Punishment
i. removal of pleasurable stimulus to decrease the behavior
a. same number of desired responses required
