The research literature with nonhumans supports findings that token economies
are a common component of training programs. The literature suggests that the
schedule by which exchange opportunities become available determines the
organization of behavioral performances in token economies to a great extent. This
study sought to systematically document whether the dynamics observed in basic
laboratory procedures will also be observed in a child diagnosed with autism spectrum
disorders and whether altering schedules by which the exchange opportunities become
available will attenuate these effects. The participant was exposed to two conditions: 1)
a fixed token-production schedule (FR1) with a fixed token-exchange schedule (FR5)
and 2) a fixed token-production schedule (FR1) with a variable token-exchange
schedule (VR5). Results of the current study did not lend themselves to draw definitive
conclusions that the patterns of responding observed in this experiment were in fact due
to the change in the token exchange schedule.
