The additional functional analysis (Figure 3) conducted with Andrew involved comparing levels of problem behavior under DRA + EXT (ESC) conditions in which demands were represented contingent upon problem behavior (i.e., a form of contingent attention) during the escape interval (DRA + EXT + Contingent Attention [CA]) or attention was provided noncontingently during the escape interval (DRA + EXT + Non contingent Attention [NCA]).
This condition was identical to the DRA + EXT (ESC) condition, except that during the escape interval, if the participant engaged in problem behavior, demands were immediately represented and continued to be presented as in DRA + EXT (ESC).
This condition was similar to the DRA + EXT (ESC) condition; however, during the escape interval, the therapist provided continuous vocal and physical attention.
