“…Indeed, functional brain asymmetries of speech (Bryden, 1979;Franzon & Hughdahl, 1986;Hausmann et al, 1998;Shaywitz et al, 1995), spatial orientation (Chiarello, McMahon, & Schaffer, 1989;Corballis & Sidey, 1993;Waber, 1982;Witelson, 1976), and face recognition (Borod, Koff, & White, 1983;Rizzolatti & Buchtel, 1977) are known to be sex-dependent in humans. Although contradictions exist (Ashton & McFarland, 1991;Boucher & Bryden, 1997;Kimura & Harshmann, 1984), the majority of data demonstrate that the lateralization of these processes is more pronounced in males, while the lateralization pattern tends to be more symmetrical in women (Corballis & Sidey, 1993;Halpern, 1986Halpern, , 1996Hausmann et al, 1998;Hough, Daniel, Snow, O'Brien, & Hume, 1994;Inglis & Lawson, 1981;Inglis, Ruckman, Lawson, MacLean, & Monga, 1982;Juarez & Corsi-Cabrera, 1995;McGlone, 1977McGlone, , 1980Rasmjou, Hausmann, & Güntürkün, 1999;Shaywitz et al, 1995). Clinical data also support these findings.…”
