ABSTRACT
There are dangers as well as difficulties in attempting an overview of research. I share the opinion of those who would argue that any authors, no matter how carefully they attempt to review a field with impartiality and rigor, are unable to shake off the effects of their own personal history and ideology. This does not mean that it is futile to make the attempt, but rather that in these postmodern times it can be helpful to acknowledge that a review of research is bound to be idiosyncratic (Harrison & Gough, 1996).
