Term
What is Classical Conditioning?
Definition
Associative learning. After repeated exposure to 2 stimuli occurring in sequence, we associate them with each other. (lightning & thunder)
Term
What is Operant conditioning?
Definition
Associative learning. adjusting to consequences of behavior so we can learn to do more of what works and less of what doesnt work.
Term
What is cognitive learning?
Definition
acquiring new behaviors/info mentally rather than direct experience. Occurs by 10 observing events and behavior of others.
2) using language to acquire info about events experienced by others.
Term
Discuss behaviorism.
Definition
term used by John B. Watson (classical conditioning) and B.F. Skinner (operant) Both believed mental life less important than behavior.
Term
Define neutral stimuli and give an example.
Definition
stimuli that doesn't trigger a responce. ex: dog hearing a bell
Term
Define unconditioned stimulus and responce
Definition
a stimulus that triggers a responce naturally before/without any conditioning.
UCS: dog food
UCR: Dog sees food and salivates
Term
Define Conditioned responce and stimulus
Definition
Conditioned Stimuli: Neutral stimulus that is given a meaning by being preceeded or followed by UCS
Conditioned responce:when two things go together for long enough, you automatically expect them to go together and respond accordingly.
Term
Define acquisition.
Definition
initial stage of learning/conditioning.
The association btw neutral stim. and unconditioned stim.
Acquisition occurs when:
UR is triggered by a CS, so the UR now becomes a CR.
Term
Define extinction and spontaneous recovery as they relate to classical conditioning.
Definition
Extinction- diminishing of a conditioned responce when US stops appearing with CS, CR decreases
Spontaneous recovery: Return of a conditioned responce after extinction and then a pause.
Term
What is generalization?
Definition
tendency to have CR triggered by related stimuli. (More similar stuff triggers CR)
Term
What is discrimination in classical conditioning?
Definition
learned ability to only repond to a specific stimuli, preventing generalization. (less similar stuff makes you not have CR)
Term
Discuss Watson's work with classical conditioning (Little Albert)
Definition
showed baby a rat (NS), wasn't scared (URC).
Made a loud noise (UCS), cried (UCR).
Showed baby a rat (NS) and made loud noise at same time (UCS), baby cried (UCR)
Show baby just the rat (now CS), no noise (CR)
Term
What is the difference between reinforcement and punishment?
Definition
Reinfocement: leads to an increase in behavior
Punishment: leads to decrease in behavior.
Term
What is Thorndikes Law of Effect?
Definition
behaviors followed by favorable consequences become more likely, and behaviors followed by unfavorable consequences become less likely.
Term
Define reinforcement.
Definition
any feedback from the environment that makes a behavior more likely to occur.
Positive: adding something desirable
Negative: Ending something unpleasant
Term
What is a primary reinforcer?
Definition
stimulus that meets a basic need or is intrinsically desirable such as food, sex, fun, attention, or power
Term
What is a secondary/conditioned reinforcer?
Definition
stimulus (like money) which has become associated with other reinforcers
Term
What is shaping by successive approximations?
Definition
when someone isnt likely to perform a behavior you are trying to teach, reward behavior that comes closer and closer to desired (tapping pens)
Term
What is discrimination in operant conditioning?
Definition
ability to become more and more specific in what situations trigger a responce.
Term
What is continuous reinforcement?
Definition
give a reinforcer after every correct performance of the behavior. (faster)
Term
What is partial reinforcement?
Definition
give reinforcers only some of the time for correctly performed behavior. behavior persists longer w/o reward
Term
What is punishment?
Definition
has opposite effects of reinforcement. consequence makes targeted behavior less likely to occur in the future.
positive: add something negative
negative: take away something pleasant
Term
What is the role of biology in classical conditioning?
Definition
easier to learn associations that make sense for survival.
food aversions can be acquired if UR doesnt immediately follow NS.
Term
What is the role of biology in operant conditioning?
Definition
encounters biological tendencies and limits that are difficult to override.
Term
What is latent learning?
Definition
learning without trying to learn and without rewards.
Term
What are the 2 processes of learning by observation?
Definition
modeling: an example of how to respond to a situation
vicarious conditioning: choices affected as we see others get consequences for their behavior.
Term
What are mirror neurons?
Definition
neurons that fire in the same patterns while we watch something happen to someone as they would if it were happening to us. (basis for observational learning)
Term
What is vicarious reinforcement?
Definition
see someone do something and get rewarded, so you do that same thing and hope you get a reward too.
Term
How does memory work?
Definition
Encoding: info gets into brain
Storage: info held in a way that allows it to be retrieved later
retrieval: reactivating/recalling info, producing it in a form similar to what was encoded.
Term
What is the difference between automatic processing and effortful processing?
Definition
Auto: implicit memories (cereb)- formed without awareness that we are building a memory and without rehearsal
Effort: explicite memory (hippo)- formed through studying, rehearsing, thinking, processing, and storing in long term memory
Term
What are chunking, mnemonics, and hierarchies?
Definition
Chunking: organizing data into manageable units
Mnemonics: connecting info to existing memory strengths such as imagery of structure
Hierarchies: branching/nested set of categories and sub-categories
Term
What is sensory memory?
Definition
consists of 3-4 second echo or 1/20th of a second image
Term
What is Iconic memory and echoic memory?
Definition
Echoic: being able to remember the last few things you hear so you can put them together and make sense of them
Iconic: being able to see individual pictures as a smooth transition of movement (movie)
Term
What is working memory?
Definition
When info from sensory memory is sent to short term memory.
you can remember 7 -+ 2 bits of info in short term memory
Term
What is long term potentiation?
Definition
change in synapses where signals are sent more effectively.
Term
How do stress hormones affect memory?
Definition
hormones trigger activity in amygdala located next to memory forming hippocampus. amygdala increases memory forming activity and engages frontal lobes to tag memories as important.
Term
What is a flashbulb memory?
Definition
emotionallt intense events that become burned in as a vivid seeming memory
Term
What role does the cerebellum play in memory?
Definition
forms and stores conditioned responces. (phobias, muscle memory)
Term
What role does the hippocampus play in memory?
Definition
responsible for explicite memories
