Your view, it seems to me, has points of contact with the behaviorist view. 
This view holds that complex human behavior is a product of classical 
conditioning, operant conditioning, as well as simpler processes that are 
observed when stimuli are simply presented repeatedly. It eschews the notion 
that behavior (human or otherwise) stems from a variety of more specific 
modules. A bigger cortex might simply mean quantitative changes in a few 
processes.
