I am very interested in Dr. Pinker's study on verbs.  As a speech-langugage pathologist I work with children who do not make the transition from regular to irregular verbs developmentally.  I also work with predomenantly autistic children and find that this area of meaning is particularly challenging for them.   Their eyes tell the story as you interact and find pathways to meaning through language, they 'light up' and spark with connections when you tap into that linguistic meaning they find so elusive.  I enjoy following your work.
