This study assessed whether four adults with multiple disabilities would su
ccessfully acquire cooperative task performance (the ability to work in dya
ds) and would prefer this over individual task performance. Analysis indica
ted that the dyads reached levels of correct responding identical to those
displayed on individual performance. Moreover, all four participants prefer
red the cooperative performance. These findings, which match those of a pri
or pilot work by Lancioni, O'Reilly, and Oliva, were discussed in terms of
their practical implications for rehabilitation and occupational contexts.
