Seven Sins of Behaviourism

First, a cautionary tale. Once upon a time there were two hard-working tailors (never mind the quality, measure the width) who promised psychology a new set of clothes. In due course, the old clothes of mentalism and introspectionism were cast off and psychology congratulated itself on its new tough look. But there were murmurings. Then one of the tailors went too far and claimed that his new clothes covered everything. Even the Emperor's Verbal Behavior! At this point a young linguist cried out ‘Transformational Grammar!’ and everyone could see that the Emperor had no clothes at all. Everyone that is apart fiom the tailors.
