“…Directly trained dependence refers to performances that indicate an initial lack of untaught mand or tact emergence following training in the other operant (Hall & Sundberg, 1987;Nuzzolo-gomez & greer, 2004;Partington, Sundberg, Newhouse, & Spengler, 1994;Sigafoos, Reichle, Doss, Hall, & Pettitt, 1990).
