ABSTRACT
A central characteristic of gender and language research is that it has been dominated by a single major theme ± that of difference. The last chapter focused on the topics of sex differences in verbal ability and sex differences in voice, which have primarily been subjects of psychological research. In that chapter I noted that an underlying assumption common to much psychological work is that essential biological characteristics are the cause, or at least the foundation, of the verbal ability or voice differences observed between men and women. However, at best, research has provided equivocal support for the idea that biological, anatomical or structural brain differences between men and women are the cause of any sex differences in voice or verbal ability.
