Problem: Reinforcers Determined by direct and/or indirect assessments, always ensure some sort of preference assessment is completed and reported. Reinforcers should be put to good use in the plan, but they may change over time so stay privy. According to the indirect assessment completed by Misha's mother, she likes the following items: Bubbles, iPad games, Thomas the Train, Bubble Guppies, Bouncy balls, and swinging. (Hint: Remember, preferred items are not automatically reinforcers. Consider the function of behavior in relation to reinforcement.) Need Assignment Help?
