Reinforcement (R+) is used to teach target skills and increase desired behaviors. Other evidence-based practices (for example, prompting, pivotal responses training) draw upon components of reinforcement. Reinforcement describes the relationship between learner behavior and a consequence that follows the behavior. The relationship between the learner's use of a skill/behavior and the consequence is only reinforcing if the consequence "increases" the likelihood the learner performs the skill or behavior. This evidence-based practice (EBP) overview on R+ includes the following packet components: (1) Overview; (2) Evidence-base; (3) Step-by-Step Guide; (4) Implementation Checklist; (5) Data Collection Sheets; (6) Tip Sheet for Professionals; (7) Parent Guide; (8) Additional Resources; (9) CEC Standards; and (10) Module References.
