Chapters 7 and 8 Flashcards
Learning
Relatively permanent change in behavior due to experience
Behaviorism
What are the underlying principles that guide learning
Associative learning
Learn to associate two events when they occur one right after the other
Classical Conditioning
Learning to behave a certain way with a certain stimulus
Pavlov’s original experiments
Working on how dogs salivate
Conditioned
learned
Unconditioned
Automatic/innate
Stimulus
Something in the environment
Response
Behavior the organism does when the stimulus is present
Extinction
Present CS w/o US repeatedly, CS stops
Spontaneous Recovery
After extinction, present CS after rest period, triggers CR
Generalization
Weaker response to a similar stimulus
Discrimination
Can train to only respond to stimulus trained on, gets rid of generalization
Biology in classical conditioning
We are prepared to make certain associations
Cognition in classical conditioning
Thinking can lessen association
Operant Conditioning
Reinforcing behavior
Skinner Box
Box with lever, food dispenser, and electrical floor
Shaping
Reinforcements that gradually guide actions toward a desired behavior
Reinforcement
Any event that increases the frequency of behavior
Positive
Adding something to the situation
Negative
Taking something away
Primary
Innately important to learner
Secondary
Have to learn, associated with primary reinforcer (i.e. money)
Immediate
Happens immediately to the learner
Delayed
Some period of time before reinforcement
Continuous
Response is reinforced every time
Partial
Give reinforcement only sometimes
Is partial or continuous learned and unlearned quickly?
Continuous
Fixed interval
Same amount of time
Variable interval
Unpredictable amount of time
Fixed ratio
Same number of times
Variable ratio
Unpredictable number of times
Punishment
Decreases frequency of behavior (positive or negative)
Biology in operant conditioning
Easiest to learn to associate behaviors that help you to survive
Cognition in operant conditioning
Still learn and think without reinforcement
Bandura’s work
Bobo doll (TV)- kids who saw violence towards the doll played with it violently
Observational learning
modelling
Applications of observational learning
Gets rid of phobias
Memory
Ability to store and retrieve information that has been learned
Flashbulb memory
Perfectly clear memory triggered by emotion
Clive
Hippocampus destroyed, cannot remember/process new things
S
Amazing memory, memorize by associating with place
Normal memory
remember meaning not detail
Information processing model
Encoding>StoringRetrieving
Encoding
Getting info into the memory system
Things Automatically processed
Space/location; Time; Frequency
Effortful Processing
Have to put in a conscious effort
Spacing effect
Space out studying and come back to it several times to remember better
Serial position effect
Remember things a the beginning and end better
Time spent
More=better
Chunking
(7-+2) Remember significant chunks better (Phone #, SSN)
Mnemonics
Study aides
Hierarchies
General topics are broken into more specific ones (textbook)
Meaningful
Personally relevant
Forgetting due to encoding
Encoding failure
Storage
Retaining
Sensory memory
Pre-sensation, extremely brief
Iconic memory
Momentary visual sensory memory
How long is an iconic memory
1/20 sec
Echoic memory
Momentary auditory sensory memory
How long is an echoic memory
3-4 sec
Short term memory
Current consciousness
Capacity of short term memory
7-+2
Duration of short term memory
30 sec
Long term memory capacity and duration
none
Neurotransmitters and hormones
More hormones= more neurotransmitters firing
Explicit/ declarative memory
Consciously know that we know (facts, dates, names, experiences)
Where is explicit memory controlled?
Hippocampus and frontal lobe
Implicit/ procedural memory
Perform action skillfully w/o being aware
Where is implicit memory controlled?
Cerebellum and basal ganglia
Retrieval
Getting info back
Recall
On the spot generation of info
recognition
ID correct info
Relearning
Knew it, forgot it, learn faster second time
Priming
When you ID an associated idea that leads you to related info
Context
Remember info better if you are in the same situation
Interference
Info in memory system is being blocked by something related
Proactive/ forward interference
Old blocks new
Retroactive/ backward interference
New blocks old
Motivated forgetting
Fred’s idea, want to forget certain (painful) memories (this is a false concept)
Memory construction
We construct our memories but can distinguish when we’ve altered our memories
