CH7: Learning Flashcards
Learning
interacting w/ enviro to prdc change in mental processes/behaviours
extinction
CS repeatedly presented w/o US causes CR to stop over time
spontaneous recovery
response randomly elicited after extinction
acquisition
gradual association of US & CS
stimulus generalization
stimuli like CS elicit CR
stimulus discrimination
stimuli like CS don’t elicit CR
biological preparedness
some NS more likely to become CS and easier
Rescorla-Wagner model
CS-US strength depends on how surprising US is
Little Albert Experiment - who? and so what?
Watson; nurture can shape anyone into anything (cl. conditioning -> behaviourism)
Thorndlike’s Law of Effect
behaviour producing good consequences will be repeated, bad consequences won’t
antecedent / discriminative stimulus
environmental event preceding behaviour
Hebb’s rule
when neurons consistently fire together (stim+resp), they wire together (association)
reinforcement
increase probability of behaviour
punishment
decrease probability of behaviour
positive
apply stimulus
