ABA Motivation & Reinforcement Alison Mummert 2011
Signals used during this training… When you see my….. You… • Hand up – Listen /Get ready • Hand drop/snap – Respond • “Everyone” -- Respond as group • Pointing at you -- Individual Responding
Behavior • - Observable/Measurable movement of a person • Analyze bx to determine it’s function. Escape/Attention/Automatic Reinforcement • Bx we want to increase or decrease. Behavior is o________ & m__________
ABC Analysis • A- Antecedent – Anything in the environment before a particular behavior. • Antecedents immediately before the bx are the most important. • A- _______________, anything in the environment b_________ the behavior.
ABC Analysis • C- Consequence – Anything in the environment after a particular behavior. • Consequences immediately after the bx are the most important. • C-_______________, anything in the environment a_______ the behavior.
Review… • Behavior is the o____________ and m______________ movement of a person. • Antecedent condition includes anything in the environment b____________ a behavior. • Consequence condition includes anything in the environment a__________ a behavior.
Motivative Operations • Motivation is an Antecedent that alters the value of reinforcers. Antecedents are environmental factors that occur________ a particular behavior. Motivation __________ the _________ of reinforcers.
Motivation ! • Motivation lies in the Environment • Affected by:Satiation/Deprivation Ex. Coffee and Environmental changes Ex. Bring out bag of chips Motivation affects the value of reinforcers! Motivation is in the ___________ and is affected by S___________/D_____________ and other E___________ changes
Reinforcement • Reinforcement is a Consequence that increases the probability of a particular behavior occurring again under similar circumstances. • Consequences occur ______________ • Reinforcement does what to behavior?______________
Reinforcement • Positive Reinforcement- Something added Ex. Candy/token • Negative Reinforcement- Something removed Ex. Timeout(demand removed) • Reinforcement increases a particular behavior. Anything that increases a particular behavior is R_____________ Something added after a particular bx that causes that bx to increase is P________ ____________. Something removed after a particular bx that causes that bx to increase is N___________ _____________.
Value of reinforcement The student will engage in behavior that is associated with a stronger motivative operation. Be sure to establish motivation! • Effort (needed to respond) The student will engage in behavior that involves less effort. Make responding easy: use errorless procedures! • Rate of Reinforcement The student will engage in behavior that most consistently obtains reinforcement. Reinforce on an appropriate variable ratio schedule! • Magnitude of Reinforcement The student will engage in behavior that obtains the greatest degree (quality and/or quantity) of reinforcement. Provide more reinforcement for better responding! • Immediacy of Reinforcement The student will engage behavior that produces reinforcement quickly. Reinforce best responding immediately!
Punishment • Consequence that decreases a particular behavior.
