“…One example in which a nonvocal behavior may not be immediately reinforced and, therefore, result in escape or avoidance of a nonpreferred or aversive stimulus is related to those situations when social partners are unfamiliar with the child and with his or her behavioral repertoire. Thus, they are unable to identify the function of the nonvocal behavior emitted by the child and do not respond to his or her communicative attempts (Matthews-Somerville & Cress, 2005; Meadan, Halle, & Kelly, 2012). When a social partner does not respond immediately to a child’s communicative attempt, the child may persist with the same nonvocal behavior (i.e., extinction burst; Lerman, Iwata, & Wallace, 1999), may engage in inappropriate behavior that was reinforced by social partners in the past (i.e., resurgence; Lieving, Hagopian, Long, & O’Connor, 2004), or may eventually refrain from further interaction because of a history of past communication failures, thereby continuing to be exposed to the aversive situation (i.e., learned helplessness or extinction; Guess, Benson, & Siegel-Causey, 1985; Seligman, 1975).…”
