Abstract
It is shown that there are two fundamental behavior functions associated with single-subject experimental research. One of these behavior functions represents the subject's orderly behavior actually occurring in the experiment of interest. This behavior function is identical to the well known individual behavior function of operant research. The other behavior function represents the subject's average orderly behavior across all possible theoretical replications of the experiment of interest. This behavior function represents, in the context of the experiment of interest, a kind of single-subject behavioral "law" peculiar to the subject under study. General approaches to investigating the two behavior functions are examined. The relationship between the two behavior functions and the importance of studying both of them are discussed.
