6 Flashcards
Acquisition:
initial stage of learning something
Avoidance learning:
organism acquires a response that prevents some aversive stimulation from occurring
Classical conditioning:
type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus
Conditioned reinforcers:
events that acquire reinforcing qualities by being associated with primary reinforcers
Conditioned response (CR):
a learned reaction to a conditioned stimulus that occurs because of previous conditioning
Conditioned stimulus (CS):
a previously neutral stimulus that has, through conditioning, acquired the capacity to evoke a conditioned response
extinction:
fading of nonreinforced conditioned response over time
Fixed-interval (FI) schedule:
the reinforcer is given for the first response that occurs after a fixed time interval has elapsed
Fixed-ratio (FR) schedule:
the reinforcer is a given after a fixed number of nonreinforced responses
Eg.) rat is reinforced for every tenth lever press
higher-order conditioning:
conditioned stimulus functions as if it were an unconditioned stimulus
Instinctive drift:
occurs when an animal’s innate response tendencies interfere with conditioning processes
Instrumental learning:
another term for operant conditioning – reinforcement or punishment are used to either increase/decrease the probability that the behaviour will occur again in the future
Latent learning:
learning that is not apparent from behaviour when it first occurs
Law of effect:
if a response in the presence of a stimulus leads to satisfying effects, the association between the stimulus and the response is strengthened
Learning:
any relatively durable change in behaviour or knowledge that is due to experience
Negative reinforcement:
occurs when a response is strengthened because it is followed by the removal of an aversive stimulus
