  4. Pigeons c: 7th session of Extd: 12th session of Ext

  5. Humans

  6. Concurrent Superstition Conc VI EXT (COD) VI EXT COD: Responses on EXT can’t be immediately followed by reinforcement for responses on VIHow 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

  7. Pigeons a: 7th session of Extb: 12th session of Ext

  8. Humans

  9. Concurrent Superstition Applied Example No COD FR 1: Mand EXT: Verbal Aggression Tx: 1) Verbal aggression followed by prompt to mand 2) Mand is reinforcedResults: Some verbal aggression is maintained by reinforcement of mand

  10. Concurrent Superstition Applied Example With COD FR 1: Mand EXT: Verbal Aggression Tx: 1) Verbal aggression followed COD 2) After COD, prompt given for mandsResults: If COD is of sufficient duration, verbal aggression should be weakened, if not extinguished

  11. Case Review Operant: Behavior  attention 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

  12. Case Review

  13. COD Duration?

  14. 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.

  15. Delay Reduction Hypothesis Problem: How long is COD? Mand Verbal Aggression Reinf: 1 every 15 minutes 1. Timeout = 5 minutes2. Prompt 3. Mand  reinf

  16. Delay Reduction Hypothesis Problem: How long is COD? Mand Verbal Aggression Reinf: 1 every 5 minutes 1. Timeout = 10 minutes2. Prompt 3. Mand  reinf
