A-B-C Data

A description of a behavior in terms of the Antecedent (A) to the behavior, the Behavior (B), and the Consequence (C) of the behavior. The antecedent is what happened immediately before the behavior, such as being ignored, wanting an item, wanting to escape a demand. The behavior is a detailed description of what the behavior looks like, for instance “tantrum” can be described as kicking, throwing objects, etc. The consequence is what was the immediate response to the behavior. This may include ignoring the behavior, giving the item to the learner, etc.
