An evaluation of convergent intraverbal instruction on tacts of features, function, or class

Abstract

AbstractEducators and parents are encouraged to arrange language‐rich environments, which provide children with exposure to language that is diverse in form and function and with repeated opportunities to emit verbal responses under a variety of conditions. Intraverbal relations constitute a large portion of these verbal interactions and may include compound antecedent verbal stimuli. Prior research has shown that responding may come under the control of limited features of compound antecedent stimuli, which may be evident when responding does not occur in the presence of individual elements or emergent performances (e.g., symmetrical relations) are absent. The current study evaluated the effects of alternating convergent intraverbal (CIV) and tact by feature, function, or class sessions on emergent tact performances in a game‐like arrangement. Participants included four children exhibiting expressive language deficits. The results revealed that correct responding on CIV trials did not consistently predict tact performances for the same targets. These findings highlight the need for additional research on the effective arrangement of compound stimuli in early educational interventions.
