How are you adjusting reinforcement to reduce maladaptive behavior? Can you reinforce a more appropriate alternative behavior to replace the maladaptive behavior?
For example, if the student rolls his eyes when he is greeted by a peer or teacher, what behavior can you identify to reinforce in its place? Perhaps an initial behavior to heavily reinforce is looking up in the direction of the speaker.
Or, if the student uses slang or informal language when greeting authority figures (e.g. teachers, administrators, supervisors), your effort is towards identifying and reinforcing more appropriate language that can replace the less appropriate language.
What are some reinforcing consequences you can deliver either immediately following the desired behavior or following a practice session– things that this particular student enjoys, wants, seeks out, etc.?
Are you using labeling and social praise to make the contingency between desired behavior and reinforcing consequence clear to the student?
For example, when the student uses an appropriate facial expression during a greeting rehearsal, are you providing specific labeling feedback as, “Great smile when you walked over to John!” or “I like how you looked towards John when you said ‘hello.’”
What reinforcing consequences can you arrange that are more naturally or intrinsically connected to this targeted behavior?
For example, if you are targeting goodbyes, it makes sense to do so at the end of the teaching period. In this way, practicing appropriate goodbyes is naturally reinforced by departure from the classroom, or from the instructional situation.
