  6. ExamplesReinforcement and Punishment Positive reinforcement: desert is provided if vegetables are finished and vegetable-eating increases in likelihood over time

  7. ExamplesReinforcement and Punishment (Positive) Punishment: a bar of soap to the mouth is delivered if a curse word is emitted and cursing decreases in likelihood over time as a result

  12. The Punishment Debate • Mooza and Leslie Grant • Autistic child head-banging • Friends at Johns Hopkins Applied Physics Laboratory • Description of device Self-Injurious Behavior Inhibiting System (SIBIS)

  13. The Debate Continues • Against: Punishment, especially involving electric shocks, must be avoided • For: Reinforcement is preferable, yes, but this technique: • Is effective in reducing and eliminating physically damaging, potentially fatal, behavior • Applies a minimal electric shock • Is paired with reinforcement • The last option • Discussion?
