“…The findings replicated those of Stromer and Mackay (1992a) and extended that study because written spelling to the computer pictures also reliably emerged (see also Kinney, Stevens, & Schuster, 1988; Goodman & Remington, 1991) and have implications for understanding the role of mediating behavior in promoting treatment generality (Gutowski, Geren, Stromer, & Mackay, 1995;see also Kirby & Bickel, 1988;Stokes & Baer, 1977; press). Overall, the present studies contribute to a growing stimulus control technology for establishing functional vocabulary skills (e.g., Browder & Lalli, 1991;Mackay, 1991;McIlvane, 1992;Remington, 1994;Singh & Singh, 1986;Stromer et al, 1992).…”
