classical conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events.
unconditioned response (UR)
In classical conditioning
Stimulus that implicitly triggers a response. (before any conditioning happens)
unconditioned stimulus (US)
In classical conditioning, an unconditioned stimulus (US or UCS) is defined as any stimulus that can naturally and automatically trigger a response
conditioned response (CR)
A learned response to a CS. (after conditioning occurs)
conditioned stimulus (CS)
The NS turns into the CS. The CS is what one would learn and, in turn, respond. (after conditioning occurs)
Neutral Stimulus (NS)
Stimulus that elicits no response (before any conditioning happens)
Acquisition
When the NS and US are linked together so that the NS triggers the CR. Through acquisition, the NS becomes the CS.
Extinction
When the CS no longer causes the CR to happen.
Spontaneous Recovery
When the CS suddenly begins to trigger the CR. (randomly after extinction)
Generalization
Triggering the CR to a stimulus similar to the CS.
Discrimination
When the CR only occurs to a specific CS.
John B. Watson’s Little Albert Experiment
used the classical conditioning model to condition a baby boy named Albert to have a phobia for white rabbits.
Higher-order Conditioning
NS become to new CS
Operant conditioning
when a behavior leads to an environmental response, which affects the likelihood of the behavior happening again.
Negative
Reinforcement
Reduce or remove an unpleasant stimulus
Behavior is strengthened
Positive Reinforcement
Add or increase a pleasant stimulus
Behavior is strengthened
Positive Punishment
Add an unpleasant stimulus
Behavior is weakened
Negative Punishment
Reduce or remove pleasant stimulus
Behavior is weakened
Fixed Ratio
Variable Ratio
Rewarded after an average but unpredictable number of responses
ratio schedule
, a certain number of behaviors must be performed before the reinforcement is provided.
interval schedule
, it means a certain amount of time must pass by, assuming the behavior is performed before reinforcement is given.
Fixed Interval
Rewarded after a set amount of time has elapsed
Variable Interval
Rewarded after an average but unpredictable amount of time has elapsed
