“…Select and reject controls have been a constant topic in matching-to-sample studies over the years (Berryman, Cumming, Cohen, & Johnson, 1965;Carr et al, 2000;de Rose et al, 2013;Dixon & Dixon, 1978;Johnson & Sidman, 1993;Kato, de Rose, & Faleiros, 2008;McIlvane et al, 1984;Stromer & Osborne, 1982). It is a relevant topic, especially because these different types of stimulus control seem to underlie different cases of complex behavior such as generalized identity or oddity from sample (Santi, 1982;Urcuioli, 1977;Urcuioli & Nevin, 1975), learning by exclusion (McIlvane, Kledaras, Munson, King, de Rose, & Stoddard, 1987;McIlvane, Munson, & Stoddard, 1988;Wilkinson, Dube, & McIlvane, 1996;Wilkinson & McIlvane, 1997), generalized conditional responding (Saunders & Spradlin, 1990Saunders & Williams, 1998) and equivalence itself (Carr et al, 2000;de Rose et al, 2013;Kato et al, 2008). Carrigan and Sidman's (1992) theoretical article proposes a research agenda that is worth pursuing.…”
