EAB Unit 3 and 4

DRA

differential reinforcement of alternate behavior

DRH

differential reinforcement of high rates of behavior

DRI

differential reinforcement of incompatible behavior

DRL

differential reinforcement of low rates of behavior

DRO

differential reinforcement of other behavior/response omission

Fixed interval (FI)

reinforcer delivered for the first response after set period of time

Fixed ratio (FR)

reinforcer delivered after set number of responses

Limited hold

window of opportunity for reinforcement in interval schedule

Ratio strain

schedule too lean to maintain behavior

Schedule of reinforcement

description of when reinforcer will be delivered

Schedule thinning

reducing schedule density

Variable interval (VI)

reinforcer delivered for first response after changing period of time

Variable ratio (VR)

reinforcer delivered for a changing number of responses

Arithmetic progression

PR increases same step size

Behavior momentum

behavior rate resist change

Breakpoint

highest completed PR schedule

Continuous reinforcement (CRF)

every response reinforced

Geometric progression

PR increases by larger and larger steps

Interreinforcement interval (IRI)

time between two reinforcers

Molecular

focus on momentary changes

Molar

focuses on overall changes

Pre-ratio pause (PRP)

SR is sdelta abating next response

Stable/steady state

predictable response pattern

Automatic

simulation directly produced by behavior

Automaticity

works without awareness

Avoidance

delay or prevent aversive

Escape

remove or decrease aversive

Negative punishment

consequence offset, behavior decrease
