Antecedent Event: A stimulus (i.e. a verbal cue, activity, event or person) that immediately precedes a behavior. This stimulus may or may not serve as discriminative for a specific behavior.

Consequence: A stimulus (i.e. a verbal response, the acquisition of a reinforcing item or activity) that contingently follows a behavior. For instance, if a little girlīs crying results in attention from her teachers, then teacher attention would be considered a consequence that followed the crying behavior.

Neutralizing Routine: A setting event intervention that is implemented before an antecedent event associated with problem behavior occurs.

Positive Behavioral Support: A comprehensive set of strategies that are meant to redesign environments in such a way that problem behaviors are prevented or inconsequential, and to teach students new skills, making problem behaviors unnecessary.

Precorrection Intervention: A strategy that involves prompting the student to use a desired behavior prior to the onset of challenging behavior.

Punishers: Consequent stimuli that reduce the probability a behavior will occur.

Reinforcers: The state of receiving or presenting a reinforcer. A stimulus that when presented immediately following a response increases the probability that the response will occur again. Can be the presentation of a reward or the removal of something unpleasant.

Setting Event: Any occurrence that affects a student's responses to reinforcers and punishers in the environment. Setting events can be due to environmental, social, or physiological factors. Occurrences that affect a behavior at one point in time may change the likelihood of a targeted behavior at a later point.

Setting Event Intervention: Strategies using information regarding social, environmental, and physiological events that may temporarily alter the value of reinforcers and punishers within the student's environment to decrease the probability problem behavior will occur. Setting event interventions may involve minimizing the likelihood of the setting event, changing expectations on days when setting events occur, or neutralizing the setting event.

Social Network: A web of interconnected people who directly or indirectly interact with or influence the student and family. May include but is not limited to teachers and other school staff, family members, friends, neighbors, community contacts, and professional support.
