📌 Implementation Guidelines

  • High Preference Items: Use for difficult tasks or new skill acquisition
  • Moderate Preference: Good for maintenance tasks
  • Rotate Reinforcers: Prevent satiation by varying rewards
  • Reassess Regularly: Preferences change over time
  • Pair with Praise: Build social reinforcers alongside tangible ones
