Conditional Probabilities
Observation Form
During a traditional Antecedent-Behavior-Consequence
(‘ABC’) recording, the observer writes a running account
of a student’s behaviors and the classroom events that
appear to trigger, or to act as consequences of, that
behavior. A drawback of ABC recordings is that they
may not show clear relationships between behaviors
and the consequences that reinforce those behaviors...

Conditional Probabilities
Observation Form
The Conditional Probabilities Observation Form (based
upon a description from Eckert, Martens, & Di Gennaro,
2005) allows the observer to compute and chart the
conditional probability that a specific consequence is
contingent on a target student behavior. This
information can be useful in completing a Functional
Behavioral Assessment and in designing behavioral
interventions.
