Term
| Alternative Schedule (alt) |
|
Definition
| Reinforcement provided to whichever schedule (interval or ratio) requirements are met first- second chance for reinforcement |
|
|
Term
|
Definition
| Collateral effect of a schedule of periodic reinforcement for other behavior; time filling or interim activities |
|
|
Term
| Chained Schedule of Reinforcement (chain) |
|
Definition
| Response requirements of 2+ schedules must be met in specific order prior to reinforcement. sD with each schedule |
|
|
Term
| Compound Schedule of Reinforcement |
|
Definition
2+ elements of (CRF), (FR, VR, FI, VI), (DRH, DRL) and extinction.
Occurring successively or simultaneously. with and without an sD, Sr+ contingent upon independent or combined elements |
|
|
Term
| Concurrent Schedules of Reinforcmennt (conc) |
|
Definition
| 2+ contingencies of reinforcement operate individually AND simultaneously for 2+ behaviors |
|
|
Term
| Conjunctive Schedules of Reinforcement (conj) |
|
Definition
| Whenever reinforcement follows completion of response requirements for both ratio & interval schedules |
|
|
Term
| Continuous Reinforcement (CRF) |
|
Definition
| Reinforcement for each occurrence of target behavior |
|
|
Term
| Differential Reinforcement of Diminishing Rates (DRD) |
|
Definition
| Reinforcement provided at the end of interval contingent upon number of responses emitted being fewer than a gradually decreasing criterion based on previous intervals |
|
|
Term
| Differential Reinforcement of High Rates (DRH) |
|
Definition
| Reinforcement provided at the end of interval contingent upon number of responses emitted being higher than a gradually increasing criterion based on previous intervals |
|
|
Term
| Differential Reinforcement of Low Rates (DRL) |
|
Definition
a) reinforcement provided following each occurrence of behavior separated by minimum interresponse time (IRT)
b)reinforcement contingent on number of responses in a period of time, not exceeding the specified criterion |
|
|
Term
|
Definition
| Reinforcement provided following first response emitted after fixed duration of time passed since last reinforced response |
|
|
Term
|
Definition
| Fixed number of responses required for reinforcement |
|
|
Term
| Intermittent Schedule of Reinforcement (INT) |
|
Definition
| Some, but not all, occurrences of target behavior produce reinforcement |
|
|
Term
|
Definition
| Reinforcement only available during finite time following elapse of FI or VI interval. Absence of target behavior during that time withholds reinforcement and restarts the interval |
|
|
Term
|
Definition
| Allocation of responses are distributed proportionally to match the rates of reinforcement from each choice in a concurrent schedule |
|
|
Term
|
Definition
| Compound schedule of reinforcment with 2+ basic schedules. alternating, random sequence. no SD. reinforcement delivered for any requirement met |
|
|
Term
|
Definition
| Compound schedule of reinforcement with 2+ basic schedules. alternating, random sequence. SD correlated with presence/absence of schedules. reinforcement delivered for any requirement met |
|
|
Term
|
Definition
| Absence of responding for a period of time following reinforcement; effect common with FI and FR schedules |
|
|
Term
| Progressive Schedules of Reinforcement |
|
Definition
| Systematically thins each successive reinforcement opportunity independent of the individual's behavior. Progressive ratio (PR) progressive interval (PI) use math/geometric progressions |
|
|
Term
|
Definition
| Behavioral effect associated with abrupt increase in ratio requirements moving from dense to thin schedules (avoidance, aggression, pauses/cessation in responding) |
|
|
Term
| Schedule of Reinforcement |
|
Definition
| Rule specifying the environmental arrangements and response requirements for reinforcement. description of the contingencies for reinforcement |
|
|
Term
|
Definition
| Changing a contingency of reinforcement by gradually increasing the response ratio or the extent of the time interval. results in lower rate of reinforcement |
|
|
Term
|
Definition
Identical to chained schedule except NO SD with the elements.
response requirements of 2+ schedules must be met in specific order prior to reinforcement. |
|
|
Term
|
Definition
| Reinforcement for the first correct response following the elapse of variable durations of time in a random, unpredictable order. Mean duration used to describe the schedule (2min+3min=5/2=VI2.5min) |
|
|
Term
|
Definition
| Reinforcement requiring a varying number of responses. Mean number of required responses used to describe the schedule (VR15) |
