Unit 2 Flashcards
What is learning
Permanent change in behavior as a result of experience
Behaviorism
Observable and measurable events
What is nonassociative learning
Respond to repeated stimulus
Associative learning
Linking 2 stimulus together
Observational learning
Change behavior for another individual
Habituation
Repeated exposure to stimulus causes a change in behavior
How is habituation measured in babies
By how long they look at some thing
Sensitization
Increase in behavior response upon repeated exposure, likely related to threatening or annoying stimuli
Desensitization
Decrease in response to increased exposure
Classical conditioning
Pavlov, food present, saliva Dash overtime didn’t have to present food just the walking caused salivation
Preconditioning Pavlov examples
The unconditioned stimulus ( Food)
Unconditioned response (salivation)
Conditioning Pavlov examples
Condition stimulus is the sound of feet conditioned response is salvation
What is the neutral stimulus in the Pavlov experiment
Footsteps, over time it becomes conditioned associative to food
What is operant conditioning
Thorndike puzzle box, we learn through trial and error which produces reward/punishment
What is the law of affect
Repeated behaviors followed by positive outcomes result in increased behavior
The subject learns solutions over time
Instrumental conditioning
Consequences of action determine the likelihood of the action happens again
Acquisition in classical conditioning
Repeated stimulus in time and space causes behavior
Key factors: time and order
Forward conditioning
Condition stimulus first then unconditioned stimulus example bell than food
Extinction in classical condition
It’s learning has taken place then unconditioned stimulus can be taken away but overtime without the unconditioned stimulus the condition stimulus will slowly go away
Spontaneous recovery
Condition stimulus re-introduced after a pause and receive spontaneous recovery of conditioned response even a strengthened response
Stimulus generalization
Tend to respond to similar stimuli to the conditioned stimuli example interchange Bella with piano note
Discrimination in classical conditioning
Overtime the animal will be able to discern the stimuli
Long delays in classical conditioning
Specific scenarios will allow a long delay to produce an association example taste aversion: hours after eating you get sick from some thing
What did JB Watson and skinner do you for behavioral study
They said that all behavior is condition/learned, suggest that phobias are learned
What was the little Albert experiment
Showed the child many animals and conditioned a phobia of them with the loud noise
Second order conditioning
Originally the bell plus the food causes the bell to become conditioned
The higher order of this is that bell and light causes elevation so then the dog is also salivating at the light
Biological preparedness
Animals are programmed to behave in a certain way because of survival, passed on those jeans because they are beneficial for example some thing that is spoiled taste bad
Antabuse
An application of classical conditioning: we throw up after alcohol so that our bodies will be alerted to it
What is reinforcement in operant conditioning
Positive outcome that reinforces for example money praise) behavior
Positive reinforcement
Adding
A satisfying fact, adding some thing non-aversive
Negative reinforcement
Removing something unpleasant/adversive stimulus like removing painful shock or the beeping noise for seatbelts
What is continuous schedule of reinforcement
Reinforced each time a behavior occurs, rewarded every single time
What is the partial schedule of reinforcement
Don’t reinforce every single time, intermediate, takes longer to condition but greater long-term persistence of behavior (gambling)
Explain ratio partial reinforcement schedule
Reinforce based on the number of times the behavior occurs
Better for longevity
Explain interval partial reinforcement schedule
Reinforced after a certain interval of time
Explain fixed partial reinforcement schedule
Every four behaviors or seconds example: make four toys, get money
Explain variable partial reinforcement schedule
Different rates/different times (most effective) example slot machine keeps you coming back because you never know when it’s gonna happen
What is positive punishment
Add something aversive for example scold a child adding a shock jail time
Negative punishment
Removing something positive for example taking food away from my hungry rat
Shaping
Reinforcing not just the final successful behavior but all the behaviors leading up to it
Latent learning
Part of the cognitive revolution, occurs without an obvious reinforcement, sometimes associations are made without reinforcement
Predisposition
Learning occurs because subjects were able to develop a cognitive map that allows them to navigate to food successfully
Insight in Layton learning
Some thing else going on in the mine that works through all possible solutions
“Aha moment”- not through reinforcement
Observational learning
More complex behaviors are learned by observing others
Control group versus experimental group in the Bobo doll study
Control group did not see a Gressitt behavior while the experimenter group saw aggressive behavior and these children not only were aggressive but added to the aggression and made it even more extreme
Acquisition phase of observational learning
Attention and retention
Performance phase of observational learning
Reproduction and motivation
Vicarious learning
Learning by watching the consequences they suffer or are rewardeded
Mirror neurons
Motor cortex there is a kind of neuron that activates both when you do something and you watch someone else do something
For example empathy, mirror neurons activated through watching empathy of others (language)
What are the four processes of memory
Encoding storage consolidation retrieval
Free recall
Recalling from nothing, remembering for example as a test pull from Emery to
Cued recall
Given hints (short answer)
Recognition in memory
Example multiple choice
Savings in memory
Relearning because we have learned at once
Atkinson and Shiffrin‘s three-part memory model
Step one: sensory input goes to sensory memory
Step two sensor remember he goes to short term memory
Step three short term memory is encoded to long-term memory
Examples of sensory memory
Iconic and echo uc: gudtation and olfaction etc., brief traces of the input are stored
What did Sperling say about sensory memory
It’s so brief that it is not stored for long even though it can be retrieved he says it progressively fades away
What is the problem with storing sensory information
By the time we start to recall it it’s faded, the decay. Similar to a trail of info
