“…In addition, previous research has indicated that there is a right-hemisphere (RH) processing advantage for audiovisually presented speech (Baynes, Funnell, & Fowler, 1994;Diesch, 1995). Bilaterality in female perceivers' neural organization has been proposed to lead to faster or more efficient processing of incongruent auditory and visual speech (Coney, 2002). In the present experiments, sex differences were found for the AV brief speech tokens, which (according to the studies cited above) engage the RH.…”

“…This appears to provide support for Jaeger et al's (1998) hypothesis that women and men differ in AV integration of speech in the context of more difficult task conditions. Previous studies have indicated that females show a greater degree of bilaterality in processing certain types of linguistic stimuli (Baxter et al, 2003;Coney, 2002;Jaeger et al, 1998;Pugh, Shaywitz, Shaywitz, Constable, et al, 1996;Rossell et al, 2002;Shaywitz et al, 1995). This bilaterality in women may lead to greater processing speed or efficiency for AV speech, yielding more visual influence for the brief visual stimuli than in men.…”

“…Jaeger et al (1998) demonstrated greater bilateral activation in the perisylvian cortex (which includes the STG, the IFG, and the adjacent premotor cortex; Riecker, Wildgruber, Dogil, Grodd, & Ackermann, 2002) for females than for males in the production of past tense verb forms. Differential patterns of processing are thought to underlie these reported sex differences (Majeres, 1999), with bilaterality affording faster and/or more efficient phonological processing for women (Coney, 2002).…”

“…These anatomic differences may lead to divergences in cognitive processing between the genders, such that females may employ a less lateralized processing than males (Coney, 2002;Voyer, 1996;McGlone, 1980). This idea has been examined in terms of actual brain/behavior relationships between the genders.…”

“…This idea has been examined in terms of actual brain/behavior relationships between the genders. While some functional brain mapping studies and behavioral studies have indicated that there are laterality differences (Coney, 2002;Walla, Hufnagl, Lindinger, Deecke, & Lang, 2001;Boucher & Bryden, 1997;Shaywitz et al, 1995), there is also conflicting evidence as well (Speck et al, 2000;Frost et al, 1999;Kertesz & Benke, 1989) indicating that both genders activate similar brain regions in language processing. Complicating the situation even further, there is one study indicating that females may be more lateralized than males (Obleser, Eulitz, Lahiri, & Elbert, 2001).…”

Imaging studies have indicated that males and females differ anatomically in brain regions thought to underlie language functions. Functional studies have corroborated this difference by showing gender differences in terms of language processing with females relying on less lateralized processing strategies than males. Gender differences in musical functions might show similar differences in functional asymmetries, although no detailed study has been performed. The current study employed a pitch memory task while acquiring functional magnetic resonance images to investigate possible differences in hemispheric processing between males and females. Gender differences were found in the time course of activation (during the first four imaging time points after the end of the auditory stimulus—“perceptual phase”—and the subsequent three imaging time points after the end of the auditory stimulus—“memory phase”) in both anterior and posterior perisylvian regions. Male subjects had greater lateralized activations (left > right) in anterior and posterior perisylvian regions during the “perceptual” as well as during the “memory” phase. There was a trend for males to have more cerebellar activation than females. Females showed more prominently posterior cingulate/retrosplenial cortex activation compared to males. Although activation patterns differed, there was no difference in the behavioral performance between both genders. These data indicate that similar to language studies, males rely more on left lateralized hemispheric processing even for basic pitch tasks.

Categorization is fundamental to our perception and understanding of the environment. However, little is known about the neural bases underlying the categorization of sounds. Using human functional magnetic resonance imaging (fMRI) we compared the brain responses to a category discrimination task with an auditory discrimination task using identical sets of sounds. Our stimuli differed along two dimensions: a speech-nonspeech dimension and a fast-slow temporal dynamics dimension. All stimuli activated regions in the primary and nonprimary auditory cortices in the temporal cortex and in the parietal and frontal cortices for the two tasks. When comparing the activation patterns for the category discrimination task to those for the auditory discrimination task, the results show that a core group of regions beyond the auditory cortices, including inferior and middle frontal gyri, dorsomedial frontal gyrus, and intraparietal sulcus, were preferentially activated for familiar speech categories and for novel nonspeech categories. These regions have been shown to play a role in working memory tasks by a number of studies. Additionally, the categorization of nonspeech sounds activated left middle frontal gyrus and right parietal cortex to a greater extent than did the categorization of speech sounds. Processing the temporal aspects of the stimuli had a greater impact on the left lateralization of the categorization network than did other factors, particularly in the inferior frontal gyrus, suggesting that there is no inherent left hemisphere advantage in the categorical processing of speech stimuli, or for the categorization task itself.
