Front 1

CRF*
(Continuous R+)

Back 1

A schedule of reinforcement that provides reinforcement for each occurrence of the target behavior

Front 2

DRD*
(Differential R+ of diminishing rates)

Back 2

A schedule of R+ in which R+ is provided at the end of a predetermined interval contingent on the # of responses emitted during the interval being fewer than a gradually decreasing criterion based on the individuals performance in previous intervals (fewer than 5/5mins, fewer than 4/5mins)

Front 3

DRH*
(Differential R+ of high rates)

Back 3

A schedule of R+ in which R+ is provided at the end of a predetermined interval contingent on the # of responses emitted during the interval being greater than a gradually increasing criterion based on the individuals performance in previous intervals (more than 3 responses/5 mins, more than 5 responses/5mins)

Front 4

DRL*
(Differential R+ of low rates)

Back 4

A schedule of R+ in which R+ is contingent on the # of responses within a period of time not exceeding a predetermined criterion

Front 5

DRO*
(Differential R+ of other behavior)

Back 5

A procedure for decreasing problem behavior in which R+ is contingent on the absence of the problem behavior during or at specific times

Front 6

FI*
(Fixed Interval)

Back 6

A schedule of R+ in which R+ is delivered for the first response emitted following the passage of a fixed duration of time since the last response was reinforced (FI3 schedule- first response after 3 minutes is reinforced)

Front 7

FR*
(Fixed Ratio)

Back 7

A schedule of R+ requiring a fixed # of responses for reinforcement (An FR4 follows every fourth response)

Front 8

INT*
(Intermittent schedule of R+)

Back 8

A contingency of R+ in which some, but not all, occurrences of the behavior produce R+

Front 9

Limited hold*

Back 9

A situation in which R+ is available only during a finite time following the elapse of an FI or VI interval; if the target response does not occur within the time limit, R+ is withheld and a new interval begins

Front 10

Post Reinforcement Pause*

Back 10

The absence of responding for a period of time following R+

Front 11

Ratio Strain*

Back 11

A behavioral effect associated with abrupt increases in ratio requirements when moving from denser to thinner reinforcement schedules; common effects include avoidance, aggression, and unpredictable pauses or cessation in responding

Front 12

VI*
(Variable Interval)

Back 12

A schedule of R+ that provides R+ for the first correct response following the elapse of variable durations of time occurring in a random or unpredictable order.

Front 13

VR*
(Variable Ratio)

Back 13

A schedule of R+ requiring a varying # of responses for R+

Front 14

Scalloped Responding

Back 14

The scallop effect refers to a post-reinforcement pause in responding during the early part of the interval. The responses are usually slow in the beginning of the interval and then accelerate toward the end. (College students writing paper)

Front 15

Schedule of Reinforcement

Back 15

A rule specifying the environmental arrangements and response requirements for reinforcement; a description of a contingency of R+

Front 16

Schedule Thinning

Back 16

Changing a contingency of R+ by gradually increasing the response ratio or the extent of the time interval; it results in a lower rate of R+ per response time

Front 17

DRA*
(Differential R+ of Alternative Behavior)

Back 17

A procedure for decreasing problem behavior in which R+ is delivered for a behavior that serves as a desirable alternative to the behavior targeted for reduction and withheld following instances of the problem behavior

Front 18

DRI*
(Differential R+ of Incompatible Behavior)

Back 18

A procedure for decreasing problem behavior in which R+ is delivered for a behavior that is topographically incompatible with the behavior targeted for reduction and withheld following instances of the problem behavior (in-seat behavior is incompatible with walking around the room)

Front 19

Full Session DRL*

Back 19

A procedure for implementing DRL in which R+ is delivered at the end of the session if the total # of responses emitted during the session does not exceed a criterion limit

Front 20

Interval DRL*

Back 20

A procedure for implementing DRL in which the total session is divided into equal intervals and R+ is provided at the end of each interval in which the # of responses during the interval is equal to or below a criterion limit

Front 21

Spaced-Responding DRL*

Back 21

A procedure for implementing DRL in which R+ follows each occurrence of the target behavior that is separated from the previous response by a minimum inter response time

Front 22

FI-DRO

Back 22

A DRO procedure in which R+ is available at the end of intervals of fixed duration and delivered contingent on the absence of the problem behavior during each interval

Front 23

FM-DRO

Back 23

A DRO procedure in which R+ is available at specific moments of time, which are separated by a fixed amount of time, and delivered contingent on the problem not occurring at those moments

Front 24

VI-DRO

Back 24

A DRO procedure in which R+ is available at the end of intervals of variable duration and delivered contingent on the absence of the problem behavior during the interval

Front 25

VM-DRO

Back 25

A DRO procedure in which R+ is available at specific moments of time, which are separated by variable amounts of time in random sequence, and delivered if the problem is not occurring at those times
