Further insights into L2 inner speech are provided by studies dealing with mental rehearsal of an L2, a language learning strategy that has been defined as “the covert practice of the L2″ (Guerrero, 1994, p. 84). Mental rehearsal appears to be a major learning strategy among L2 students. It has been associated with repetition (Chamot, 1987; O’Malley, Chamot, Stewner-Manzanares, Russo, & Ktipper, 1985), practice (Rubin, 1987), advance preparation (Chamot, 1987), and production (Tarone, 1983) of the L2. O’Malley et al. (1985) found that within eleven cognitive strategies reported by beginning and intermediate ESL students, repetition-a strategy that involves silent
rehearsal-had the highest percentage of use.
Of course, verbal rehearsal in short-term memory has been for years associated with long-term recall (Bransford, 1979; Craik & Lockhart, 1972; Houston, 1986). More recently, research within the working-memory model (as discussed in Chapter 2) has stressed the importance of rehearsal in long-term retention of FL vocabulary among adults (Baddeley et al., 1998; Gathercole & Thorn, 1998). Several studies (Ellis & Beaton, 1993; Ellis & Sinclair, 1996; Papagno, Valentine, & Baddeley, 1991; Service, 1992; Service & Kohonen, 1995) have found that audible and subvocal repetition have positive effects on long-term retention of words43 and that suppressing rehearsal produces negative effects. It has also been suggested that gifted language learners, or people that appear to have a natural talent for learning FLs, have superior phonological loop skills, that is, excellent use of the mechanism involving articulatory rehearsal (inner voice) and phonological memory (inner ear) (Baddeley et al., 1998). Evidence for this link between language ability and phonological memory was presented in Papagno and Vallar’s (1995) study of “polyglots.”
References connecting mental rehearsal and inner speech abound. One of the earliest is an observation made by Vygotsky (1986) himself. In his comment that inner speech “serves as preparation for external speech-for instance, in thinking over a lecture to be given” (p. 88), Vygotsky was assigning a rehearsal role to inner speech.
In 1983, Smith equated rehearsal with the usual practice of “talking to oneself,” a form of inner speech “by which we prepare for something we might want to say” or by which “we recapitulate and elaborate upon conversations after the event” (p. 90). In 1987, Rohrer argued that inner speech is “the language of the mind” (p. 92), used in various mental operations, one of which is rehearsal. In 1990, Murphey reviewed studies conducted on the “din in the head,” linking this phenomenon to Vygotsky’s concept of inner speech: “What [Vygotsky] calls inner speech may have a strong
connection to what is now being called the Din” (Murphey, 1990, p. 55). In all these references, it appears that mental rehearsal, both in the LI and the L2, is tightly linked to inner speech.
