Hemispheric Asymmetry in Lexical Decisions: The Effects of Grammatical Class and Imageability

“…In our study, the male results are consistent with those reported by Day (1977Day ( , 1979 and Mannhaupt (1983): words with a higher imageability level are processed without visual field asymmetries, the superiority of RVF appearing in words with a lower capacity to evoke an image. Thus, our results support an imageability effect in hemispheric differentiation for word processing.…”

“…Imageability failed to interact with visual field in various studies (e.g., Bradshaw, Nettleton, & Taylor, 1981;Howell & Bryden, 1987;McMullen & Bryden, 1987). In contrast, Day (1977Day ( , 1979 and Mannhaupt (1983) report that performance asymmetry varied as a function of word imageability/or concreteness. However, the conclusions of these studies must be viewed with caution.…”

“…Despite the great number of studies, results regarding the role of such factors are not yet conclusive. According to some authors, the habitual right visual field advantage-left hemisphere superiority (RVF-LH) attenuates or even disappears when concrete and/or highly imageable and/or high frequency words are presented (e.g., Day, 1977Day, , 1979Ellis & Shepherd, 1974;Hines, 1976Hines, , 1977Mannhaupt, 1983;Young & Ellis, 1985). Other studies, however, have not observed relevant effects from these variables (e.g., Boles, 1983;Howell & Bryden, 1987;Koening, Wetzel, & Caramazza, 1992;Lambert & Beaumont, 1983;Leiber, 1976;McMullen & Bryden, 1987).…”

Cerebral Laterality for Famous Proper Nouns: Visual Recognition by Normal Subjects

“…LH association with lexical processing has also been found in studies of split-brain patients (Sidtis, Volpe, Holtzman, Wilson, & Gazzaniga, 1981;Zaidel, 1977) and observations in Wada testing (Loring, Meador, Lee, & King, 1992;Loring, Meador, Lee, Murro, Smith, Flanigin, Gallagher, & King, 1990). However, some ability of the RH to process lexical items, especially those that are short, frequent, and concrete, is consistently reported in the split-brain studies mentioned above, in visual half-field studies (Day, 1977;Mannhaupt, 1983;Chiarello, 1988aChiarello, , 1988bChiarello, , 1988cBurgess & Livesay, 1998), in brain damage (Van Lancker, 1988;Code, 1987;Kinsbourne, 1971;Czopf, 1981;Cummings, Benson, Walsh, & Levine, 1979;Landis, Graves, & Goodglass, 1982;Landis, Regard, Graves, & Goodglass, 1983), in Wada testing (Hart, Lesser, Fisher, Schwerdt, Bryan, & Gordon, 1991), and in adult left hemispherectomy (Burkland & Smith, 1977). Several studies report that the RH processes lexical items in different ways from the LH (Drews, 1987;Landis & Regard, 1988;Rodel, Cook, Regard, & Landis, 1992;Chiarello, 1988b;TenHouten, Hoppe, Bogen, & Walter, 1986).…”
