Effects of Minimal versus Lengthy Delay between Simulated and in Vivo Instruction on Community Performance 1

A combination multiple probe and alternating treatments design was employed to determine the effects of the timing of simulated training, relative to in vivo training, on the community fast food restaurant performance of two students with severe handicaps. The results indicated no differential effects of simulation immediately prior to, versus 1 1/2 hour prior to, in vivo instruction. Maintenance data suggested skill retention as much as seven weeks following program completion.
