Learning Flashcards
Learning
long-lasting change in behavior resulting from experience
Classical conditioning
type of learning where people and animals can learn to associate neutral stimuli (ex: sound) with stimuli that produce reflexive, involuntary responses (ex: food) and will learn to respond similarly to the new stimulus as they did to the old one (ex: salivate).
Neutral stimuli
stimuli that only focuses attention
Unconditioned stimulus/US/UCS
original stimulus that elicits a natural, reflexive response
Unconditioned response/UR/UCR
the natural response elicited from the unconditioned stimulus
Conditioned response/CR
the learned response to a previously neutral stimulus
Conditioned stimulus/CS
the originally irrelevant stimulus that now triggers a conditioned response after association with an unconditioned stimulus
Acquisition
the acquiring of a new behavior that occurs once one responds to the CS without the US present
Delayed conditioning
acquisition with the presentation of the CS followed by the US
Trace conditioning
acquisition with the presentation of the CS, followed by a short break, followed by the presentation of the US
Simultaneous conditioning
acquisition with the presentation of the CS and the US at the same time
Backward conditioning
acquisition with the US presented first, followed by the CS
Extinction
the process of unlearning a behavior, achieved when the CS no longer elicits the CR
Spontaneous recovery
phenomenon where the CR briefly reappears upon presentation of the CS after a CR has been extinguished and no further training has taken place
Generalization
the tendency to respond to similar CS’
Discrimination
the ability to tell the difference between various stimuli
Aversive conditioning
conditioning to avoid the US
Second-order/Higher-order conditioning
the brief use of a CS as a US to elicit a new stimulus (only possible once a CS elicits a CR)
Learned taste aversions
the aversion developed to certain foods due to illness after ingestion
Salient stimuli
easily noticeable stimuli
Garcia effect
the ease with which animals learn taste aversions that occurs whenever nausea is paired with food or drink
Operant conditioning
type of learning based on the association of consequences with behaviors
Law of Effect
law that states that if consequences to a behavior are pleasant, the stimulus-response connection will be strengthened, increasing the likelihood of that behavior; if consequences to a behavior are unpleasant, the stimulus-response connection will weaken, lessening the likelihood of that behavior
Skinner Box
a box that delivers food to animals with a lever to press or disk to peck
Reinforcer
any event that makes the behavior more likely to occur
Reinforcement
the process of reinforcing a behavior
Positive reinforcement
the addition of something to increase the likelihood of a behavior occurring
Negative reinforcement
the removal of something to increase the likelihood of a behavior occurring
Escape learning
the termination of an aversive stimulus
Avoidance learning
the avoidance of an aversive stimulus
Punishment
anything that makes a behavior less likely to occur
Positive punishment (usually referred to as punishment)
the addition of something unpleasant to make a behavior less likely to occur
Omission training/negative punishment
the removal of something pleasant to make a behavior less likely to occur
Shaping
technique that reinforces the small steps used to reach the desired behavior
Chaining
technique that links together separate behaviors into a complex activity
Primary reinforcers
reinforcers that are rewarding
Secondary reinforcers
reinforcers that we value
Token economy
system that uses tokens as rewards for performing desired behaviors
Premack principle
principle that states that more probable behaviors can be used to reinforce less probable behaviors
Continuous reinforcement
the reward of a desired behavior continuously
