The reductive effects of noncontingent reinforcement: Fixed-time versus variable-time schedules.
Journal of Applied Behavior Analysis,
34, 505-509.
The effects of fixed-time (FT) and variable-time (VT) schedules
on responding were evaluated with 2 adults with mental
retardation. Multielement and reversal designs were used to
compare the effects of FT and VT schedules in reducing responses
previously maintained on variable-ratio reinforcement schedules.
The schedules were equally effective in reducing the target
behavior.
