  5. Small-n Designs • Behavior often cannot be studied in large groups (large-n designs) • Small-n frequently used in therapeutic situations • Reversal designs: ABA or ABAB • A = baseline recording of behaviors • B = introduction of treatment • IV is essentially treatment / no treatment.

  6. Increases Bill crys Adults attend Example: Crying Behavior Reinforcement + Removing the positive reinforcement (attention) extinguishes crying behavior.

  8. Multiple Baseline Designs • Observe different behaviors, before and after learning. • Can be done two ways: • Observe multiple behaviors in one individual -- like a within-subject design • Observe a single behavior in different individuals – between-subjects • Treatments are introduced at different times.

  9. Example: Siblings Compared • 3 pairs of autistic vs normal siblings • Baseline -- observed target behaviors (counting, letter ID, etc) • Treatment -- trained normal sib to reinforce behaviors of autistic sib • DV -- number of correct performances of behaviors.

  10. Changing Criterion Design • Instead of comparing different people or different behaviors, progress in shaping behavior over time is measured. • The target behavior needed for reinforcement is changed as a behavior is acquired. • Range-bound changing criterion – instead of a target, a range for reinforcement is established. • Distributed-criterion design – targets are spread across several behaviors.
