6) Learning Flashcards
Define classical conditioning.
A type of learning through which an organism learns to associate one stimulus with another
What is an unconditioned response? Give examples.
o A response that is elicited by an unconditioned stimulus without prior learning
o Examples: Salivation, startle, contraction of pupil, eyeblink response
What is an unconditioned stimulus? Give examples.
o A stimulus that elicits a specific unconditioned response without prior learning
o Examples: Food, loud noise, light in the eye, puff of air
What is a conditioned stimulus? Give examples.
o A neutral stimulus that, after repeated pairing with an unconditioned stimulus, becomes associated with it and elicits a conditioned response
o Example: Musical tone
What is a conditioned response? Give examples.
o The learned response that comes to be elicited by a conditioned stimulus as a result of its repeated pairing with an unconditioned stimulus
o Example: Salivation to the tone
In Ivan Pavlov’s classical experiment, what is the food?
Unconditioned stimulus
In Ivan Pavlov’s classical experiment, what is the salivation to the tone?
Conditioned response
In Ivan Pavlov’s classical experiment, what is the musical tone?
Conditioned stimulus
What is higher-order conditioning?
Conditioning that occurs when conditioned stimuli are linked together to form a series of signals
In classical conditioning, what is extinction?
In classical conditioning, the weakening and eventual disappearance of the conditioned response because of repeated presentation of the conditioned stimulus without the unconditioned stimulus
In classical conditioning, what is spontaneous recovery?
The reappearance of an extinguished response (in a weaker form) when an organism is exposed to the original conditioned stimulus following a rest period
In classical conditioning, what is generalization?
In classical conditioning, the tendency to make a conditioned response to a stimulus that is like the original conditioned stimulus
How could Ivan Pavlov’s classic experiment have been generalized?
By using a different musical tone
In classical conditioning, what is discrimination?
The learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimulus but not to similar stimuli
In Little Albert’s experiment, what was the conditioned stimulus, the unconditioned stimulus, and the conditioned response?
CS: White rat
US: Loud noise
CR: Fear reaction
What is operant conditioning?
A type of learning in which the consequences of behavior are manipulated so as to increase or decrease the frequency of an existing response or to shape an entirely new response
In operant conditioning, what is an operant?
A voluntary behavior that accidentally brings about a consequence
In operant conditioning, what is a reinforcer?
Anything that follows a response and strengthens it or increases the probability that it will occur
In operant conditioning, what is a punisher?
Anything that follows a response and weakens it or decreases the probability that it will occur
In operant conditioning, what is shaping?
An operant conditioning technique that consists of gradually molding a desired behavior (response) by reinforcing any movement in the direction of the desired response, thereby generally guiding the responses toward the ultimate goal
In operant conditioning, what is successive approximations?
A series of gradual steps, each of which is more similar to the final desired response
In operant conditioning, what is extinction?
In operant conditioning, the weakening and eventual disappearance of the conditioned response as a result of the withholding of reinforcement
In operant conditioning, what is generalization?
In operant conditioning, the tendency to make the learned response to a stimulus similar to that for which the response was generally reinforced
What is reinforcement?
Any event that follows a response and strengthens or increases the probability that the response will be repeated
What is positive reinforcement?
Any pleasant or desirable consequence that follows a response and increases the probability that the response will be repeated
What type of learning behavior is the example:
Person buys more lottery tickets after hitting a $100 jackpot
Positive reinforcement
What type of learning behavior is the example:
College student studies more often after getting an A on an exam for which she studied more than usual
Positive reinforcement
What type of learning behavior is the example:
Rat learns to press a lever to obtain a food pellet
Positive reinforcement
What type of learning behavior is the example:
Rat learns to press a lever to turn off an annoying stimulus such as a loud buzzer
Negative reinforcement
What type of learning behavior is the example:
College student studies more often in order to avoid getting another F on an exam
Negative reinforcement
What type of learning behavior is the example:
Individual calls his mother more often in order to keep the mother from nagging him
Negative reinforcement
What is a primary reinforcer?
A reinforce that fulfills a basic physical need for survival and does not depend on learning
What is a secondary reinforcer?
A reinforce that is acquired or learned through association with other reinforcers
