Antecedent
What does the “A” in ABC stand for?
Antecedent
What does “behavior” mean in ABA?
Anything a person does that can be observed and measured
What does “C” stand for in the ABCs of behavior?
Consequence
Name the 4 main functions of behavior.
Attention, Escape, Tangible, Sensory
The therapist says, “Clean up!” The client throws blocks. The therapist withholds attention. What is the A, B, and C?
A: “Clean up!”; B: Throws blocks; C: Attention withheld
True or False: The antecedent refers to how long it takes for a behavior to begin after a cue.
False
Which of these is NOT a behavior: crying, being sad, or clapping?
Being sad
True or False: Consequences only happen after problem behavior.
False. (After any behavior)
A student screams when given work and the teacher removes it. What’s the function?
Escape
A child claps when the therapist praises them. Behavior increases. What’s the consequence?
Positive reinforcement
Give one example of an antecedent.
.
The “B” in ABC represents what we can directly _____.
Observe
An RBT gives a client a break after they start whining. The whining increases. What type of consequence occurred?
Negative reinforcement, the whining removed the demand.
A client spins a toy over and over again while being in his room alone. What’s likely the function?
Automatic/Sensory
Identify the potential function: The client covers ears when the vacuum turns on.
Escape/Sensory
What type of antecedent increases the likelihood of behavior by signaling reinforcement is available?
Discriminative stimulus (SD)
An RBT note states, “Client was upset and didn’t want to work” as their behavior note.
What’s wrong with this behavior description?
t’s not observable or measurable, “upset” and “didn’t want” describe emotions, not behavior.
If a child gets attention after yelling and yelling increases, what type of consequence is that?
Positive reinforcement
A child cries to get candy from mom. What is the likely function?
Tangible
A client hits their leg when asked to write. The RBT shortens the task and gives praise for writing one word.
What function is being addressed, and what strategy is used?
Escape
Demand fading with reinforcement for task engagement.
A client engages in self-injury primarily when the RBT transitions from a preferred to a non-preferred activity. The RBT begins giving a 2-minute warning before transitions and allows the client to bring one preferred item to the next task.
What type of antecedent strategy is being used?
Transition warning and noncontingent access to preferred stimuli
Name 3 measurable dimensions of behavior.
Frequency, duration, latency, intensity
A client follows directions only when the RBT offers candy but stops when it’s gone.
What does this tell you about the consequence?
The reinforcement wasn’t maintained, the behavior was dependent on the tangible, not naturally reinforced.
A client makes loud noises during every activity, even when alone.
What is the most likely function of the behavior?
Automatic (sensory) reinforcement.
During group time, a client yells jokes. Peers laugh, and the behavior continues.
What’s the function, and what could the RBT do first?
Function: Attention
Action: Withhold peer attention and reinforce appropriate ways to get it (e.g., raising hand or waiting turn).
