Abstract
In recent years there has been a striking shift in both academic and popular discourse on the subject of malefemale differences. It is increasingly common for biological explanations to be proposed for differences that had previously been treated by most investigators as effects of socio-cultural factors. This article critically examines the arguments as they apply to the specific case of malefemale differences in linguistic behaviour. It concludes that the relevant linguistic research evidence does not on balance support the new biologism; that evidence is more adequately accounted for using the socio-cultural approaches which most linguistic researchers favour
