“…The cross-referencing of the terms gives rise to linkages that suggest areas of fruitful empirical study (e.g., relations among coding, tacting, and remembering), and other potentially productive linkages are implied (e.g., relations among equivalence, intraverbal behavior, and verbal learning; adduction, abstraction, productivity, and recombinatory generalization). Research ideas also may be derived from (a) recent theoretical discussions about the role of verbal behavior in stimulus class formation and other complex behaviors (e.g., Horne & Lowe, 1996;Stromer et al, 1996), (b) renewed interest in interventions that concentrate on the function of verbal behavior rather than its structure (e.g., Charlop-Christy & LeBlanc, 1999), and (c) the development of specialized language interventions and broad curricula based on Skinner's ideas (e.g., Bondy & Frost, 1993;Brady et al, 1994;Shafer, 1994;Sundberg & Partington, 1998).…”
