Learning Theories Flashcards
Pavlovian Conditioning
-aka classical or respondent conditioning
-controlled by antecedents (before the behavior)
-unconditioned- hardwired
-conditioned- learned in environment
-example: Dog with bell and food…
neutral-bell, unconditioned stimulus- food, unconditioned response- salivation; turns into bell-conditioned stimulus when paired with steak, salivation is the conditioned response to the bell
Details of Classical Conditioning
- greater number of pairings= more likely to have a CR
- most likely to occur if the CS precedes the UCS by 0.5 seconds
- often unconscious!
- conditioned responses can happen after one experience (PTSD)
Counterconditioning
- eliminating a CR by pairing a CS to a US that elicits a new response that is incompatible with the old one
- teaching another association
- Mary Cover Jones- treated boy terrified of rabbits
- Wolpe- systematic desensitization to treat phobias
Extinction
- occurs when the CS is repeatedly presented without the UCS
- bell, bell, bell with no meat
- Bouton- proposed that this is not extinction but rather learning a new association
- simply doing something enough and having a safe experience can extinct something
Higher-order conditioning
when a CS is paired with a second CS, so that the second CS produces a similar CR to the one elicited by the first CS
- ex. with a bell, buzzer, and salivation
- higher-order responses are not as strong because the natural response is not there
Operant Conditioning
- controlled by its consequences
- paying attention to what happens after the behavior
- reinforcements or punishers
- operants serve functions
Reinforcement
- a consequence that increases the probability of a behavior recurring
- positive: something is added (get paid money)
- negative: something is removed (anxiety is reduced)
- ** both lead to increases in behavior!
Punishment
- a consequence that decreases the probability of a behavior recurring
- positive: adds something (spanking)
- negative: taking something away (time out- taking away play time)
Examples of punishment and reinforcement
- fastening a seat belt (negative reinforcement-likelyhood of gettin hurt is reduced)
- mother stops nagging when the child cleans their room (negative reinforcement- annoyance is reduced)
- a child gets candy when they pick up their toys (positive reinforcement)
- putting ointment on a bug bite (negative reinforcement- the itch is decreasing)
- a parent takes away the use of a car when a teen comes home late (negative punishment)
- a parent gives a child extra attention when they misbehave in a store (positive reinforcement)
- a woman goes to work early so she doesn’t arrive late (negative reinforcement- taking away the punishment for being late)
Principles of Operant Conditioning
- Consequences exert more control when they occur immediately
- Shaping is developing a new behavior by rewarding successive approximations to that behavior; doesn’t happen all at once (ex. Class paying more attention when the teacher was on the right side of the room)
- punishment is most effective when combined with a reinforcement
Observational learning
- watching a model’s behavior be rewarded or punished
- ex. Bandura with Bobo dolls
- more likely when you identify with the model or when the model is admired
Mowrer’s Two-Factor Theory
- respondent and operant stages
- explains avoidance behavior (*anxiety disorders!)
ex. -For someone who is avoiding driving on bridges: - stage 1, driving on a bridge is pared with a spontaneous panic attack
- stage 2- avoidance behavior- not driving over a bridge- is negatively reinforced
Avoidance Behavior Theory
- Seligman and Johnston
- Dogs learned to jump over a barrier to escape an electric shock. Next, a bell (CS) was paired with the shock (UCS) and the dogs learned to jump after the bell to avoid the shock
- BUT when the shock stopped the dogs still jumped
- Explained by…
- Avoidance behavior strengthens the first belief. They had to teach the dog using a harness to avoid the avoidance behavior
- exposure and response prevention
