“…The current data suggest that not all of a child's novel vocalizations are acquired through imitation, in that at least some responses are acquired through automatic reinforcement. However, these newly acquired vocalizations are still a function of environmental variables, rather than the frequently proposed cognitive and physiological variables (e.g., Chomsky, 1959;Ervin-Tripp, 1964;McNeill, 1970 The analysis of automatic reinforcement also appears relevant to a number of complex human behaviors, such as thinking and creativity (Vaughan & Michael, 1982), the acquisition of syntax and grammar (Braine, 1963), equivalence relations (Palmer, 1996), and self-stimulation (Lovaas, Newsom, & Hicknan, 1987). It also has implications for a wide range of topics frequently discussed in linguistics and psychology such as accents, bonding, problem solving, perception, academics, literature, performing arts, and pathologies (Vaughan & Michael, 1982).…”
