4.1.1 classical conditioning Flashcards
define cc
learning through association
unconditioned stimulus (UCS)
produces natural and unlearnt response (e.g. food)
neutral stimulus (NS)
not associated with UCS. can be an environmental stimulus that does not naturally produce a behavioral response (e.g. a bell)
unconditioned response (UCR)
occurs naturally without being learnt (e.g. salivation)
conditioned stimulus (CS)
new stimulus that is associated with UCS so it produces the same response on its own
conditioned response (CR)
behaviour caused by the CS
equation of cc when food and bell is associated
• Before conditioning
Bell (NS) —> no response
Food (UCS) —> salivation (UCR)
• During conditioning
Bell (NS) + Food (UCS) —> salivation (UCR)
• After conditioning
Bell (CS) —> salivation (CR)
describe stage 1 (before conditioning)
- the UCS produces the UCR
- stimulus produces natural and unlearnt behavior
- NS does not produce a response
describe stage 2 (during conditioning)
- NS is associated with the UCS multiple times so that it becomes the CS
- one trail learning can occur
describe stage 3 (after conditioning)
NS becomes CS and is associated with UCS so produced the CR
extinction
CS is continually presented without UCS then CR gradually dies out (e.g. food makes you ill but after a while you are fine with eating it again)
spontaneous recovery
CR is not reinforced so it becomes extinguished, but after a while the CR reappears
generalization
extension of the CR from the original stimulus to similar stimulus (e.g. if you drink milk and it makes you ill so you refuse to eat yogurt)
discrimination
the CR is only produced by the presentation of the original stimulus, it does not extend to similar stimulus
(e.g. dog does not salivate to a diff bell / metronome)
one trial learning
when conditioning appears immediately after 1 trial only
