ABSTRACT
With the emergence of cognitive science, a new form has been given to an old question. In its original form, the question was whether differences in intellectual capability were best thought of as stemming from differences in a single, underlying intellectual factor, or whether they were better thought of as stemming from the differential development of a number of more discrete mental faculties. In its modern form, the question has been phrased in more technical terms: Is the mind better thought of as a general, all-purpose computing device, whose particular forte is general problem solving? Or is it better thought of as a modular device, each of whose modules has evolved to serve a unique biological function that it performs in its own unique and specialized way?
