Recently I have grown interested in the correlation between MBTI types and cerebral hemispheres. Although the resources on this issue are fairly small in number, most of those which I have seen seem to declare that by rule all Ps have a right-hemisphere preference, and Js have a left-hemisphere preference. Precisely how accurate is this claim? Such sources also go on to classify which four functions are left-brain functions, and which four are right-brain functions.
Now, the behavioral correlations are quite obvious (P/right-hemisphere = tactics and flexibility, J/left-hemisphere = strategy and rigidity). It is quite clear that SJs are left-brain thinkers and NPs are right-brain thinkers. However, does this mean that NJs have a left-hemisphere preference, and SPs a right-hemisphere preference? Is this J/P hemisphere preference a rule or a generalization with exceptions. Does this also go as far as learning preferences? Does this mean that Js are more auditory/sequential and Ps more visual/spatial?
What is your personal opinion? Which of the four functions are left-brain functions and which are right-brain functions?
