Dm. Richman et al., Response efficiency during functional communication training: Effects of effort on response allocation, J APPL BE A, 34(1), 2001, pp. 73-76
An analogue functional analysis revealed that the problem behavior of a you
ng child with developmental delays was maintained by positive reinforcement
. A concurrent-schedule procedure was then used to vary the amount of effor
t required to emit mands. Results suggested that response effort can be an
important variable when developing effective functional communication train
ing programs.
