Mini Chap Seven Flashcards
Habituation
Respond less strongly over time to repeated stimulus
Sensitization
Increased behaviour from repeated stimulus
Classical conditioning
Animals respond to previously neutral stimulus paired with another stimulus
-automatic response
Operant conditioning
Controlled by consequences of organisms behaviour
UCS
Stimulus that elicits automatic response without prior conditioning
UCR
Automatic response to non neutral that does not need to be learned
NS
Does not naturally elicit a response
CR
Response elicited by CS
CS
Previously neutral
-now elicits a response when paired with UCS
Acquisition
Learning phase with established conditioned response
Extinction
Reduction and elimination of CR after CS presented repeatitively without a UCS
Spontaneous recovery
Reemergence of extinct conditioned response following extinction procedure
stimulus generalization
CS are similar but not identical to original CS that elicit CR
Stimulus discrimination
Display less pronounced CR to CS that differ from original CS
Higher order conditioning
Develop CR to CS by association with another CS
Renewal effect
Sudden re emergence of CR following extinction when returned to environment where CR was acquired
Thorndike law of effect
Cats try escaping box and faster they get out faster they get food
-higher chance of having behaviour with a reward or reinforcement
BF Skinner box
Allow periods of conditioning to be administered and behaviours recorded unsupervised
-first exposed to stimulus then response, then response is reinforced
Discriminative stimulus
Stimulus associated with prescience of reinforcement
Fixed ratio
Provide reinforcement following regular number of responses
Variable interval
Provide reinforcement at least once during average random time interval
Fixed interval
Provide reinforcement for a response at least once following specific time period
Variable ratio
Provide reinforcement after specific number of responses on average/random
Premack principle
Reinforce lower probable behaviour using opportunity to engage in higher probability behaviour
Secondary reinforces
Neutral object that becomes assosciated with primary reinforcer
Latent learning
Is not directly observable
Mirror neurons
Perform and observe action allows neuron to be activated
Insight learning
Grasp underlying nature of problem
Instinctive drift
Return to innate behaviour following repeated reinforcement
Learning styles
Preferred method of acquiring new infor
Latent inhibition
Difficulty establishing CC to CS we repetitively experience without having a UCS
Law of effect
If stimulus is followed by behaviour and reward the stimulus is more likely to have behaviour in future
