The effects of choice and no choice of reinforcer on the response
rates of 3 children with autism were compared across
single-operant and concurrent-schedule procedures. No consistent
differences in responding between choice and no-choice components
emerged during single-operant phases. During the
concurrent-schedule phases, however, all participants had
substantially higher rates of responding to the button that led
to a choice among reinforcers than to the button that did not
lead to choice.
