This study evaluated how children who exhibited functionally equivalent problem and appropriate behavior allocate responding to experimentally arranged reinforcer rates. Relative reinforcer rates were arranged on concurrent variable-interval schedules and effects on relative response rates were interpreted using the generalized matching equation.…

If the members of a functional response class occur in a predictable order, a response-class hierarchy is said to exist. Although this topic has received some attention in the applied literature, it remains relatively understudied. The purpose of the current investigation was to develop an analogue model of a response-class hierarchy. Children…

Extinction-induced resurgence is the recurrence of previously reinforced behavior when another behavior is placed on extinction (Lieving, Hagopian, Long, & O'Connor, 2004). This phenomenon may account for some instances of treatment relapse when problem behavior recovers during extinction-based treatments. The current study sought to determine…

The current study consisted of 2 parts, with the same 4 normally developing 4-yr-old children employed across both parts. The primary aim of Part 1 was to replicate previous research on exemplar training and its impact upon the emergence of repertoires of derived symmetry or mutually entailed relations. In this part of the study, the children were…
