learning 1 Flashcards
what is habituation
most basic form of learning, reduction in response due to a repeated stimulus
what is classical conditioning
associating one stimulus with another
US
unconditioned stimulus - biologically significant, elicts reflexive unlearned response
UR
unconditioned response - reflexive unlearned response to stimulus
CS
conditioned stimulus - previously neutral stimulus but after pairing with a US elicts a conditioned response
CR
conditioned response - response elicted by the CS
what is the US, UR,CS and CR in pavlovs dog exp.
US - food
UR - salivation
CS - tone
CR - salivation when tone and no food
what is aquisition
first stages of learning when the response is eastablished - when the US evokes the CS
what is trace conditioning
CS terminated before delivery of the US
CS and UCS are not presented together and don’t overlap - they do overlap for a time in normal conditioning
what is extinction
presentation of CS alone - no US - results in weakening of the CR over time
what is spontaneous recovery
CR appears after extinction and rest - next day
stimulus generalisation
stimuli that are similar to the CS elicit a CR
3 applications for conditioning techniques
fear - behavioural therapy, advertising, hospital visits
what did watson and rayner do
11 month old infant - didnt like loud noises - after 7 pairings of rat and noise he would cry at the sight of a rat
