Unit 5 Flashcards
2 Variable attributes of antecedents
Can be either outside or within the skin of the organism, can be social or non-social
2 Basic types of antecedents
Discriminative Stimuli (SD) and Motivating Operations (MOs)
Unconditioned motivating operation
A motivating operation whose value-altering effect does notdepend on a learning history
Conditionedmotivating operation
A motivating operation whose value-altering effect depends on a learning history
2 Types of effects antecedents have on behavior
Evocative (evoke behavior) or Abative (abate behavior)
Operant conditioning
The basic process by which operant learning occurs
Evocative Effect
An increase in the momentary frequency of a response class now, under the current conditions
Abative Effect
A decrease in the momentary frequency of a response class now, under the current conditions
Differential reinforcement
Reinforcing only those responses within a response class that meet a specific criterion along some dimension(s) and placing all other responses in the class on extinction
Differentiation
When differential reinforcement consists of reinforcing some responses and not reinforcing other responses
Discrimination
When differential reinforcement consists of reinforcing aresponse when certain stimuli are present and not reinforcing the same response when those stimuli are not present.
Stimulus Control(Discriminative Control)
The tendency of behavior to occur more frequently in the presence of a particular stimulus because the behavior has been reinforced only or mostly in the presence of that stimulus
Discriminated Operant
An operant class that is established through the process of differential reinforcement with respect to the presence or absence of antecedent stimuli
Discriminative stimulus (SD)
An antecedent stimulus thatevokes or abates a specific behavior, due to a past history of differential availability of reinforcement or punishment for that behavior, dependent on their presence versus their absence
4 Basic types of Discriminative Stimuli
SD for reinforcement
SD for extinction
SD for punishment
SD for withholding punishment
