Question | Answer |
---|---|
Learning | change in an organism's behavior or thought as a result of experience |
Classical Conditioning | learning through association of paired stimuli |
who identified classical conditioning | Ivan Pavlov |
% features of classical conditioning | 1. Neutral Stimulus 2. Unconditioned Stimulus 3. Unconditioned Response 4. Conditioned Stimulus 5. Conditioned Response |
Neutral stimulus | until conditioned to pair with something else, the NS has no impact 1. no biologically imperative response 2. non-threatening, non-activating |
What does unconditioned stimulus lead to? | leads to unconditioned response reflexively, automatically |
acquisition | phase when CR is established (new association is acquired/learned) |
extinction | reduction/elimination of CR after CS presented repeatedly without UCS |
Spontaneous Recovery | when conditioning returns (often less strong) after having been previously extinguished |
Renewal effect | when conditioning extinguished in one context re-appears in another |
Stimulus generalization | similar CS's eliciting same CR (different bell pitch giving the same response) |
Stimulus discrimination | when CS are too different and no longer elicit the same CR (or any response at all) |
preparedness | when a stimulus is easily associated due to its type |
latent inhibition | when conditioning difficult to establish due to prior or other frequent encounters with NS by itself |
Higher Order Conditioning | process of developing classically conditioned responses to CS's associated with original CS |
Operant conditioning | aka "instrumental conditioning" learning controlled by the consequences of the animals voluntary behavior |
consequences | can be good, bad, neutral, exciting, boring |
Law of effect | If we're rewarded for a response to a stimulus, we're more likely to repeat that response to the stimulus in the future. |
reinforcement | increases probability of behavior |
punishment | decreases probability of behavior |
positive | giving or adding a stimulus |
negative | removing or taking away stimulus |
positive reinforcement | adding some stimuli to the subject which is meant to increase the desired behavior |
negative reinforcement | removing some stimuli, which is then meant to increase the desired behavior |
positive punishment | adding some stimuli which is meant to decrease an undesirable behavior |
negative punishment | removing some stimuli, which is then meant to decrease an undesirable behavior |
which is more effective punishment or reinforcement | reinforcement is more effective |
reinforcement schedule | refers to a pattern of delivering reinforcers |
continuous reinforcement | consequences linked to behavior every time |
partial reinforcement | consequences occur some of the time |
ratio | reinforcement administered based on the number of behaviors committed |
interval | reinforcement administered based on time spans |
observational learning | learning through watching others |
