Term
Spontaneous Recovery
Definition
The sudden and temporary reappearance of a Bx following extinction
Term
Discrimination
Definition
Reinforcing a response when certain stimuli are present but NOT reinforcing the SAME response when those stimuli are not present; S-R-S contingency
Term
differentiation
Definition
Reinforcing some responses and NOT reinforcing other RESPONSES
Term
Differential Reinforcement
Definition
Consists of two operations: reinforcement and extinction (not reinforcing); R-S contingency
Term
DRL-T=Differntial Reinforcement of low rates of responding-time
Definition
This schedule consists of responses reinforced only if they are emitted after a specified amount of time has elapsed since the last response; criterion is set at a time above the avg IRT.
Term
DRL=Differential Reinforcement of low rates of responding
Definition
These schedules of reinforcement require that a maximum number of responses occur in a given time period; criterion set just slightly below avg baseline
Term
Spaced Responding DRL or DRL-T
Definition
DRL like the DRL-T
Term
interval DRL
Definition
DRL in which you break time period into shorter intervals and reward at the end of each segment
Term
Full-Session DRL
Definition
DRL using an entire time period as the criterion; ex: whole class period
Term
Operant extinction
Definition
the process by which a previously reinforced behavior is weakened by withholding reinforcement
Term
Operant behavior
Definition
Behavior which has an effect on the environment
Term
Extinction burst
Definition
when behavior is no longer reinforced, the behavior immediately and temporarily will increase in frequency, duration, and intensity before it decreases
Term
Sensory Extinction
Definition
Extinction consists of masking the sensory consequences of the Bx
Term
DRO=Differential reinforcement of other Bx
Definition
Schedule of reinforcement in which reinforcement is delivered whenever a specified amount of time has elapsed in which a specified Bx does not occur; used to decrease the rate of problem Bx; time interval usually set lower than the avg IRT
Term
DRI=Differential Reinforcement of Incompatible Bx
Definition
Schedule of reinforcement in which reinforcement is delivered whenever a response occurs that is physically incompatible with the target Bx; it cannot occur concurrently with a specified target Bx
Term
DRA=Differential Reinforcement of Alternative Bx
Definition
Schedule of reinforcement in which einforcement is delivered whenever a response occurs that may compete with the target Bx; the alternative BX are functionally equivalent to the target inappropriate Bx; target Bx not reinf., alternative Bx is reinforced
Term
Matching Law
Definition
Behavior that's reinforced by the most powerful reinforce & by denser schedule will occur more frequently than Bx that is reinforced by thinner schedules & less magnitude
