Toward establishing a qualifying autoclitic repertoire in children with autism spectrum disorder

Abstract

Autoclitics are secondary verbal operants that are controlled by a feature of the conditions that occasion or evoke a primary verbal operant such as a tact or mand. Qualifying autoclitics extend, negate, or assert a speaker's primary verbal response and modify the intensity or direction of the listener's behavior. Howard and Rice (1988) established autoclitics that indicated weak stimulus control (e.g., “like a [primary tact]”) with four neurotypical preschool children. However, generalization to newly acquired tacts was limited. In Experiment 1, we addressed similar behavior as in Howard and Rice but with autistic children while using simultaneous teaching procedures, and we observed generalization across sets and with newly acquired tacts. In Experiment 2, we evaluated the effects of multiple-exemplar training on generalization of autoclitics across sets of naturalistic stimuli. Across participants, gradual increases in the frequency of autoclitics occurred with untaught stimuli after teaching with one or more sets.
