“…However, greater attention to sample size and replication is needed. The current study, as well as earlier reports (Boles, 1995;Frost et al, 1999;Hiscock & MacKay, 1985;Shapleske et al, 1999;Sommer et al, 2004Sommer et al, , 2008Springer et al, 1999), provides substantial evidence for what might be termed a "sex similarities" hypothesis (Hyde, 2005) of lateral brain organization. If little or none of the variation in asymmetry can be attributed to sex, this implies that most of the individual variability remains to be explained by other factors.…”

Although left hemisphere language specialization is one of the most widely reported findings in human neuropsychology, some studies have found evidence for more bilateral language organization in women. We report findings of a large scale, multi-task investigation of sex differences in both structural asymmetries and lateralization of word reading. Two hundred participants were tested in eight divided visual field lexical tasks, and each received a structural MRI scan. We examined whether there was evidence for sex differences in overall measures of neuroanatomical and behavioral lateralization, in specific language tasks and brain regions, and in variation in asymmetry within and across tasks and brain regions. There was very little evidence for sex differences on any behavioral measure. The few indications of sex differences in the current report accounted for 2% or less of the individual variation in asymmetry and could not be replicated in independent subsamples. No sex differences were observed in the asymmetry of structures in Broca’s and Wernicke’s area such as pars triangularis, pars opercularis, the planum temporale, planum parietale, or Heschl’s gyrus. There were also no sex differences in the variability of neuroanatomical asymmetries within or between brain regions. However, a significant relationship between planum temporale and behavioral asymmetry was restricted to men.

“…The data of the present study, however, corroborate other studies (Bryden 1975;Carr 1969;Hiscock and Mackay 1985;Hynd and Obrzut 1977;Kraft 1982;McKeever and Van Deventer 1977;Nachshon 1986;Scott et al 1979) which do not show sex differences in dichotic listening, thus further extending those findings across languages. However, in view of the inconsistency in the available data, it is evident that the issue of sex differences in dicho tic listening remains inconclusive.…”

Greater right ear advantage in dichotic listening to English-spoken digits among English-speakers than among Japanese-and Hebrew-speakers (Hatta and Dimond 1981; Nachshon 1986) was attributed either to effects of lingustic properties of the respective native languages, or to the sequence of language acquisition. In order to evaluate the two alternative hypotheses, 112 English-Hebrew and 140 Hebrew-En&sh bilinguals recalled a series of three-digit dichotic sets. Differential ear advantages were expected on the basis of the two hypotheses. Data analysis showed, however, that while recall was better for digits spoken in the native than in the non-native languages, no significant differences in right ear advantage between the two groups were found. Procedural effects might account for this result.The notion that hemispheric asymmetry may vary across languages has recently gained a considerable amount of support (Hatta and Dimond 1981;Moss et al. 1985;Scott et al. 1979;TenHouten et al. 1976;Tsao and Wu 1981;Van Lanckner and Fromkin 1973). For example, in one of their studies Hatta and Dimond (1981) presented English-spoken digits, paired with various environmental sounds, to English-and Japanese-speakers. Both groups showed right ear/left hemisphere advantage (REA) in digit recall which was, however, significantly greater for the English-than for the Japanese-speakers.The authors accounted for this differential performance in terms of effects of certain linguistic properties of the subjects' native languages. Specifically, Hatta and Dimond (1 98 1) argued that since Japanese is moreThe author thanks Nili Arkin and Yosef Gabai for testing subjects.

“…However, these findings are not consistent across studies (Hiscock, Inch, Jacek, Hiscock-Kalil, & Kalil, 1994). Some studies have shown larger asymmetry in men than women (Cowell & Hugdahl, 2000;Weekes, Zaidel, & Zaidel, 1995) while others have not (Demarest & Demarest, 1981;Foundas, Corey, Hurley, & Heilman, 2006;Hiscock & MacKay, 1985). Cowell and Hugdahl (2000) showed that REA decreased with age in women and increased with age in men across the adult lifespan.…”
