Start with Halpern's "Sex Differences in Cognitive Abilities" and follow the bibliography where it takes you (I really would like to provide the references, but just I don't have the patience to copy them now). For something rigorous that's digitally available, start with sapinker's slides from his 2005 debate [1]. Modern understanding is quite similar, only with new evidence and insights from evolutionary psychology and neurobiology.
