"The pop psychology notion of a left brain and a right brain doesn’t capture their intimate working relationship. The left hemisphere specializes in picking out the sounds that form words and working out the syntax of the phrase, for example, but it does not have a monopoly on language processing. The right hemisphere is more sensitive to the emotional features of language, tuning-in to the slow rhythms of speech that carry intonation and stress."
While over-generalized and overstated by popular psychology and self-help texts, understanding your strengths and weaknesses in certain areas can help you develop better ways to learn and study. For example, students who have a difficult time following verbal instructions (often cited as a right-brain characteristic) might benefit from writing down directions and developing better organizational skills. The important thing to remember if you take one of the many left brain/right brain quizzes that you will likely encounter online is that they are entirely for fun and you shouldn't place much stock in your results.
Frontal Lobe Hypothesis - University of Reading
The next important problem with prior conceptualizations of EF, again noted by Dimond (1980) and later others (Hayes et al., 1996), is attributing "a central executive" to the PFC. This was the initial mistake made by Pribram (1973) and it has been repeated since that first appearance of the term executive as applied to the functions of the PFC. Saying that the PFC is the brain's executive installs a , a homunculus of the mind, or marionette operator (Grafman, 1995) into the PFC that serves to explain nothing and will eventually require its own explanation. Saying that the PFC is the brain's central executive merely begs the issue of just who or what is this wizard behind the curtain that is pulling all these levers in managing the lower level non-executive brain systems so as to direct behavior across time toward future goals. Just who or what is even choosing these goals and for whom are they being chosen? It is surely not some little CEO of a large corporation or a symphony conductor installed in the brain as suggested in the analogies so often used as exemplars of EF in the trade literature. Yet most models of EF include some thinly veiled reference to some sort of "mini-me" homunculus that is doing our bidding, as Hayes et al. (1996) noted.
