Conc VI EXT (COD)
VI EXT
COD: Responses on EXT can’t be immediately followed by reinforcement for responses on VI
How CODs are programmed: 1) Timer starts after each EXT response or 2) timer starts after switching to VI. During timing, reinforcement is unavailable for responses to VI

Concurrent Superstition
Applied Example No COD
FR 1: Mand EXT: Verbal Aggression
Tx: 1) Verbal aggression followed by prompt to mand 2) Mand is reinforced
Results: Some verbal aggression is maintained by reinforcement of mand
Concurrent Superstition
Applied Example With COD
FR 1: Mand EXT: Verbal Aggression
Tx: 1) Verbal aggression followed COD 2) After COD, prompt given for mands
Results: If COD is of sufficient duration, verbal aggression should be weakened, if not extinguished

Current Procedure: (Tx)
1) Behavior = inapp vocals and provoking others2) Tx = a) Prompt to mand for activity of choice
Probe: (Tx1)
1) Behavior = inapp vocals and provoking others2) Tx = a) Prompt to go to room under observation for 5 minutes b) Prompt to mand for activity of choice

Delay Reduction Hypothesis
•Stimuli will function as conditioned reinforcers if they signal a reduction in the average delay to reinforcement.
•Or, given the choice between 2 stimuli, organisms will choose the stimulus that is “closer” to positive reinforcers, or “farther” from negative reinforcers.
Delay Reduction Hypothesis
Problem: How long is COD?
Mand Verbal Aggression
Reinf: 1 every 15 minutes
1. Timeout = 5 minutes2. Prompt 3. Mand reinf
