Freeland, J. T., & Noell, G. H. (1999). Maintaining accurate math responses in elementary school students: The effects of delayed intermittent reinforcement and programming common stimuli. Journal of Applied Behavior Analysis, 32, 211-215.

This study examined the effect of delayed reinforcement on digits completed by elementary school children and the effect of programming stimuli common to reinforcement conditions on the maintenance of their performance. Participants exhibited similar levels of responding during intermittent and continuous reinforcement. Responding continued for a number of sessions at similar levels during a maintenance phase that included stimuli present during delayed reinforcement.
