Chapter 7 Flashcards
learning
relatively permanent behavior change due to experience
learned associations
feed our habitual behaviors (habituates)
conditioning
process of leaning associations
classical conditioning
learn to associate two stimuli and thus anticipate events
operant conditioning
we learn to associate a response (our behavior) and its consequence and thus repeat acts followed by good results and avoid acts followed by bad results
observational learning
learn from other’s experiences
Pavlov
- dog experiments
- laid foundation for John Watson (behaviorist)
behaviorism
view that psychology:
- should be an objective science
- studies behavior without reference to mental processes
neutral stimulus (NS)
events the dog could see or hear but didn’t associate with the food
unconditioned response (UR)
(CC) the unlearned, naturally occurring response to the unconditioned stimulus (US)
(dog salivation when food is in mouth)
unconditioned stimulus (US)
(CC) stimulus that unconditionally (naturally and automatically) triggers a response
(food)
conditioned response (CR)
(CC) the learned response to a previously neutral (but now conditioned stimulus (CS)
operant chamber (Skinner box)
containing a bar or key that an animal can manipulate to obtain food/water reinforcer; attached devices record the animal’s rate of bar pressing
reinforcers
(OC) any event that strengthens the behavior that follows
positive reinforcement
increasing behavior by presenting positive stimuli (presented after response–strengthens response)
negative reinforcement
increasing behaviors by stopping/reducing negative stimuli
stimuli removed after a response–strengthens the response
primary reinforcers
an innately reinforcing stimulus (such as one that satisfies biological need)
not learned
conditioned reinforcer
stimulus that gains its reinforcing power through its association with a primary reinforcer
(aka secondary reinforcement)
(immediate and delayed reinforcers)
-turning on light and getting food
(reinforcement schedules)
continuous reinforcement
reinforcing the desired response every time it occurs
(reinforcement schedules)
partial (intermittent) reinforcement
reinforcing a response only part of the time; results in slower acquisition of a response (but increases resistance to extinction)
(reinforcement schedules)
fixed-ratio schedule
(OC) reinforces a response after specified number of responses
(reinforcement schedules)
variable-ratio schedule
(OC) reinforces a response after an unpredictable number of responses
(reinforcement schedules)
fixed-interval schedule
(OC) reinforces a response only after a specified time has elapsed
(reinforcement schedules)
variable-interval schedule
(OC) reinforces a response at unpredictable time intervals
