BEHV 101 Week 4 Flashcards
Escape Contingency
Response terminates an ongoing stimulus
Avoidance Contingency
Response prevents/postpones the presentation of a stimulus
Discriminated Avoidance
Responding in presence of a signal prevents aversive stimulus onset
Unconditioned Negative Reinforcer
Stimulus that functions as negative reinforcer with no prior learning
Conditioned Negative Reinforcer
Previously neutral stimulus that functions as negative reinforcer because of learning history
Behavioral Contrast
Behavior changes if there’s difference in location (e.g., home versus school), people (e.g., parents versus teachers), or both
Free-Operant Avoidance
Responding any time prevents stimulus onset
Schedule of Reinforcement
Rule that describes contingency of reinforcement
FR1
Continuous reinforcement schedule
Continuous Reinforcement (CRF)
Each occurrence of behavior is reinforced
Intermittent Reinforcement (INT)
Some, but not all, occurrences of behavior are reinforced
Ratio Schedules
Reinforcement for number of responses emitted
Interval Schedules
Reinforcement delivered for first response after amount of time
Fixed Ratio (FR)
Reinforcement after a fixed number of responses
Post-Reinforcement Pause
No responding for a period following reinforcement
Schedule with high rate of reinforcement and post-reinforcement pause
Pattern of Responding ➡️ Fixed Ratio (FR)
Variable Ratio (VR)
Reinforcement after a variable number of responses
Schedule of reinforcement that produces consistent quick steady rates of responding
Pattern of Responding ➡️ Variable Ratio (VR)
Fixed Interval (FI)
Reinforcement for first response following a fixed duration of time
Schedule that produces scallop effect
Pattern of Responding ➡️ Fixed Interval (FI)
Variable Interval (VI)
First response that occurs after variable amount of time elapsed produces reinforcement
Schedule that produces constant but generally low rates of responding
Pattern of Responding ➡️ Variable Interval (VI)
Limited Hold
Reinforcement available for finite amount of time following the elapse of the FI or VI interval
Schedule Thinning
Making availability of reinforcement less over time
