Unit 6- Learning Flashcards
learning
acquiring new info/behaviors
habituation
decrease response to stimulus with repeated exposure
associative learning
learning certain events occur together
stimulus
event/situation that evokes response
cognitive learning
acquisition of mental information through observation and information, rather than by direct experience
classical conditioning
learns to link 2 or more stimuli and anticipate events
behaviorism
studies behavior without reference to mental processes
neutral stimulus (NS)
elicits no response before conditioning
unconditioned response (UR)
naturally occurring response to US
unconditioned stimulus (US)
naturally triggers a response (UR)
conditioned response (CR)
learned response to previously neutral stimulus
conditioned stimulus (CS)
originally irrelevant stimulus, but after association with US, triggers CR
acquisition
one links NS and US, NS then triggers CR
higher-order conditioning
a new NS can become new CS, second conditioned stimulus, turning a
NS into a CS by associating it with another
CS
extinction
diminishing of conditioned response
spontaneous recovery
reappearance, after pause, of conditioned response
generalization
similar stimuli elicit similar responses
discrimination
learned ability to distinguish between CS and irrelevant stimuli, ability to only
respond to a specific stimuli,
preventing generalization.
operant conditioning
behavior strengthened/diminished with reinforcements or punishments
law of effect
behaviors followed by favorable consequences are more likely, vice versa
operant chamber
contains key/bar that animal manipulates for food/water reinforcer, skinner box
reinforcement
event that strengthens behavior
shaping
guide behavior toward desired behavior
discriminative stimulus
elicits response after association with reinforcement, For example, dogs, rats, and even spiders can be trained to search for very specific smells, from drugs to explosives
positive reinforcement
increase behaviors by presenting positive reinforcers
negative reinforcement
increase behaviors by stopping/reducing negative stimulus
