Continuous Schedule of Reinforcement (CRF)
Every correct response is rewarded (used for Acquisition).
Partial (or intermittent) Reinforcement Schedule (PRF) types (for fluency)
Fixed Ratio (FR), Variable Ratio (VR), Random Ratio (RR), Fixed Interval (FI), Variable Interval (VI)
Fixed Ratio (FR)
A fixed ratio schedule refers to applying the reinforcement after a specific number of behaviors. Real-world example: FR10" = Used car dealer gets a $1000 bonus for each 10 cars sold on the lot. activity slows after reinforcer and then picks up
Variable Ratio (VR)
This refers to applying a reinforcer after a variable number of responses. Slot Machine effect.
Fixed Interval (FI)
Refers to applying a reinforcer after a specific amount of time. Exmp: getting a raise every year and not in between. activity increases as deadline nears, can cause fast extinction
Random Ratio (RR)
An unpredictable # correct responses will be rewarded.
Variable Interval (VI)
The first response after a variable time interval is reinforced. ex: Checking VM, calls come in @ various times. steady activity results, good resistance to extinction
Differential Rates Reinforcement Schedule
Differential reinforcemnt of high rates of behavior (DRH), Differential reinforcemnt of low rates of behavior (DRL)
Differential Types of Reinforcement Schedule
Differential reinforcement of other behavior (DRO), differential reinforcement of incompatible behavior (DRI), Differential reinforcement of excellent behavior (DRE)
Differential reinforcement of other behavior (DRO)
Rewarding all other behaviors beside the one you are trying to eliminate ex: standing, sitting or shaking paw instead of jumping.
Differential reinforcement of incompatible behavior (DRI).
Reward only incompatible behavior (counter-commanding, alternative response training). Used to reduce a frequent behavior without punishing it
Differential reinforcement of excellent behavior (DRE)
Only the very best responses are rewarded.
Duration Reinforcement Schedule
Fixed duration (FD), Variable Duration (VD), Random Duration (RD) Teach duration by 1st varying and making time random.
Fixed Duration (FD)
Behavior must be engaged in for a fixed amount of time in order to receive reinforcement. Ex: an hourly employee
Interval of time the behavior must be engaged in varies
Ex: waiting to cross a busy intersection
Primary Reinforcer (unconditoned reinforcer)
stimulus that does not require pairing to function as a reinforcer (food, water etc)
. the taking away of an aversive stimulus to increase certain behavior or response-relief.
the amount of time that passes between reinforcers
Based on the number of responses learners give between reinforcers
Negative punishment (omission training)
the taking away of an appetitive stimulus to decrease a certain behavior (frustration)
secondary reinforcer/ conditioned reinforcer
has acquired its function as a reinforcer after pairing with a stimulus that functions as a reinforcer. example: clicker sound, "yes".
