More on "left brain / right brain" pop psychology, and why it is incorrect: 4. Is the left analytical and logical, and the right intuitive? There's no evidence for that, really, and that represents a gross misunderstanding of how language, intuition, math, music, or whatever work in the brain. To say that language can be reduced to something logical and analytical is terribly simplistic, and reflects a total ignorance of linguistics and langauge structure. Traditional logical cannot explain how semantics, pragmatics, the lexicon, syntax, phonology, and morphology function or interact in a way that we can produce and comphrehend langauge. In fact, non-traditional types of logic form the basis of more recent linguistic and psycholinguistic theories, like connectionism, optimality theory, cognitive linguistics, and dual route processing models. These are based on optimization logic, or abduction (as the philopher Peirce described it; it is also the type of logic behind game ...

Okay, I want to rant and vent about this pop pscyhology stuff that keeps popping up. As a linguist and cognitive psychologist, I find references to "left brain / right brain" annoying, and this stuff pops up on the Internet, in business or marketing contexts, in sermons, on TV, etc. This is pop psychology because it is a grossly inaccurate distortion of what psychology and neuroscience tells us about differences between the two brain hemispheres, and is always misapplied. It is wrong for these reasons. 1. You use all of your brain all the time, not just half of it (unless you're a politician or TV/movie celebrity). Just because the whole think doesn't light up under an MRI or CT scan at a given moment doesn't mean the rest is dormant; it's working, too, just at a lower level. And there's more than the left and right cerebral cortices (upper advanced mammalian brain) that this pop theory refers to. There's the front brain (frontal corex), which is neith...
