imagine a child who is not doing his or her schoolwork. Regardless of the childs actual diagnosis, how might you try to determine if this represented inattention or impulsivity, as in attention deficit/hyperactivity disorder (AD/HD), as opposed to deliberate refusal, as in oppositional defiant disorder (ODD)? Keep in mind that these children will probably not give much useful information in response to direct questions about why they engaged in a particular action.
