Learning Flashcards
(23 cards)
Ivan Pavlov
All learning is based on reflex
Associate a neutral stimulus with an unconditional response
(Used dogs to collect saliva to study it for digestive properties but discovered the dog learn to salivate)
Classical Conditioning
Study of how we acquire or change behaviors
Learning
Present the conditional stimulus (CS) enough times alone (without the US) that it no longer elicits the conditional response CR)
Extinction
Even though the shower is fixed, person still jumps at the sound of the flush
Example of Spontaneous Recovery
Response to approximations of the original CS
Generalization
Respond to specific CS
Discrimination
Second-hand conditioning does not happen to you directly
Vicarious Classical Conditioning
Learning based on rewards & punishments
Operant Learning
Anything that increases the likelihood of a behavior reoccurring
Reinforcements (RF)
Unlearned
Food, water, sleep, warmth
Primary Rewards
Learned
Money, need for achievement, want control
Secondary Rewards
Brings pleasure
Positive RF
Removes discomfort
Negative RF
Any behavior that is rewarded will more likely be replaced
Thordites “Law of Effect”
Adversative stimulus
Anything you do not like
Punishments
T-timing
I-intensity child will grow up to model parents behaviors;escape
C-
Punishing Children
How rewards are delivered
Schedules of RF
Get a reward for every correct response
Continuous RF
Get a reward on a non-continuous basis
Partial or Non Continuous RF
Get a reward after a set period of time passes
Fixed Interval
Ex: FI 60 minutes: as the reward period approaches response rate increases
When you get a reward after an average period of time passes
Variable Ex: 60min -30min -50min -90min -110min Average = 60min
You get a reward after a set number of responses
Fixed Ratio
FR10= 10x
Get a reward after an average # of responses
Variable Ratio Ex: VR30= 30x -25 -35 -10 -50 Average is 30 -Slot Machines
