Week 7 Flashcards

Intermittent Reinforcement
Is an arrangement in which a behavior is positively reinforced intermittently rather than every time it occurs
Response Rate
Refers to the number of instances of a behavior that occur in a given period of time
Schedule of Reinforcement
Is a rule specifying which occurrences of a given behavior, if any, will be reinforced
Continuous Reinforcement
Each instance of behavior is reinforced
Extinction
A behavior that used to be reinforced no longer receives reinforcement
Intermittent Schedules of Reinforcement
- Only some responses are reinforced
- Are used to strengthen behaviors that have already been established
Ratio Schedules of Reinforcement
Requires a number of responses before one response produces reinforcement = doing
Interval Schedules of Reinforcement
Requires time to elapse before a response produces reinforcement
Fixed-Ratio (FR) Schedule
The reinforcer is delivered after every X responses where X is the size of the ratio
Variable Ratio (VR) Schedule
The reinforcer is delivered after a variable number of responses, based on an average
Ratio Strain
A behavioral effect associated with sharp increases in ratio requirements when moving from dense (FR 1, FR 2, FR 3…) to thin (FR 20, FR 30, FR 40…) schedules
Free-operant Procedure
The individual is free to respond at various rates – there are no limits
Fixed Interval (FI) Schedules
A reinforcer is delivered following the first instance of a response after a fixed period of time
Discrete-trial (restricted operant) Procedure
The individual’s responding is limited by environmental constraints
Variable Interval (VI) Schedules
Reinforcement is delivered for the first correct response following variable lengths of time, based on an average
Limited Hold
A deadline for meeting the response requirement of a schedule of reinforcement
Concurrent Schedules of Reinforcement
When each of two or more behaviors is reinforced on different schedules at the same time, the schedules of reinforcement are concurrent
