Chapter 6- Learning Flashcards
learning
a long lasting change in behavior resulting from experience
acqusition
when the subject responds to the CS without of presentation of the US and has acquired a new behavior
extinction
the process of unlearning a behavior
spontaneous recovery
sometimes, after a conditioned response has been extinguished and no further train of the animals has taken place, the response briefly reappears upon presentation of the conditioned stimulus
generalization
the tendency to respond to similar CSs
discrimination
subjects can be trained to tell the difference between various stimuli
classical conditioning
people and animals can learn to associate neutral stimuli with stimuli that produce reflexive, involuntary responses and will learn to respond similarly to the new stimulus as they did to the old one
unconditioned stimulus
something that elicits a natural, reflexive response (food)
unconditioned response
the natural, involuntary response (salivation)
conditioned stimulus
something that, after conditioning, elicits the natural, reflexive response but would not do so without conditioning (bell)
conditioned response
the response that after conditioning, elicits the natural, reflexive response but would not do so without conditioning (bell)
aversive conditioning
subjects can be conditioned to have a negative response to a stimuli
second-order or higher-order conditioning
once a CS elicits a CR, it is possible, briefly, to use that CS as a US in order to condition a response to a new stimulus
learned taste aversion
when you ingest an unusual food or drink and then become nauseous, you will probably develop an aversion to that food or drink
operant conditioning
a kind of learning based on the association of consequences with one’s behaviors
law of effect
if the consequences of a behavior are pleasant, the stimulus-response connection will be strengthened and the likelihood of the behavior will increase. however, if the consequences of a behavior are unpleasant, the S-R connection will weaken and the likelihood of the behavior will decrease.
instrumental learning
learning in which the consequence is instrumental in shaping future behaviors
Skinner box
an experimental tool that has a way to deliver food to an animal and a lever to press or disk to peck in order to get the food
reinforcer, reinforcement
a desirable stimuli, the process of giving a desirable stimuli to a subject
positive reinforcement
the addition of something pleasant
negative reinforcement
the removal of something unpleasant
positive punishment (punishment)
the addition of something unpleasant
negative punishment or omission training
the removal of something pleasant
shaping
reinforces the steps used to reach the desired behavior
