“…Several studies have shown that tact, textual (visual), and echoic (vocal) prompts may be used to transfer control to verbal stimuli when teaching intraverbals to children with and without developmental disabilities (e.g., Goldsmith, LeBlanc, & Sautter, 2007;Ingvarsson, Tiger, Hanley, & Stephenson, 2007;Miguel, Petursdottir, & Carr, 2005;Valentino, Shillingsburg, & Call, 2012). The few studies comparing prompt topographies (Finkel & Williams, 2001;Ingvarsson & Hollobaugh, 2011;Ingvarsson, & Le, 2011;Vedora, Meunier, & Mackay, 2009;Vedora & Conant, 2015;Wallace, Bechtel, Heatter, & Barry, 2016) have found that the most effective and efficient prompt varied across participants. Some authors hypothesized that the success of a specific prompt may depend on an individual's learning history (Finkel & Williams, 2001;Ingvarsson & Hollobaugh, 2011).…”
