For long I've seen uncountable number of blogs, websites, tutorials, booklets about career-guide, self-improvement, meditation, parenting etc. claiming;
"Right hemisphere loves to work random, creative way; in contrast left-hemisphere loves to follow instructions and discipline."
"Right hemisphere takes part in lateral-thinking; in contrast left-hemisphere takes part in vertical thinking."
"Right hemisphere deals with pictures, visions, senses, feelings etc; in contrast, Left hemisphere deals with formula, equation, numbers, names, letters, calculations etc."
"Right hemisphere works in nonlinear, meshy manner; in contrast, Left hemisphere works in linear, rigid, sequential way.
"Right hemisphere see the whole, big-picture. Left hemisphere see one part only".
Thus I developed a concept about behavior of 2 hemisphere.
Now While I was going through following research article (of 2000):
Cerebral specialization and interhemispheric communication by M. Gazzaniga (pdf) ,
I stuck on a diagram telling the exact opposite.
(I've slightly edited the screenshot to enlarge the text and utilize the whitespace).
The only thing of the paper maches with popular view, is; the right hemisphere is taking important part in understanding pictures, geometric shapes, extrapolating to fill a gap in an image, etc.
But according to this diagram; actually Left hemisphere is site for viewing the 'big-picture' of a subject ('living things'), finding 'similarity' (sings, eats, has a etc). Also From personal experience, the way of thinking shown as relational-map at left hemisphere, is the cause of 'randomness' in me, so that I keep many books and files scattered while working; or was broken line (que) in school to collect a grass or stone. The thing shown at left side forces me to collect various objects and arrange them... not the rightward one. Also I zone-out too-much and day-dream because of the left-one... not the right-one.
In contrast, clearly the right-hemisphere in this diagram, is processing information in much rigid, linear or sequential, disciplined way; and looking a small-part... not the big-picture.
So, please could anyone explain me, why should I still have to consider left hemisphere as a rigid linear servant and right-hemisphere as rulebreaker daydreaming artist?
(P.S. most of these popular-series's tell that Right hemisphere is intuitive and Left hemisphere is logical. But I can't believe this because I can't separate logic and intuition. Logic is the bridge between intuition and reality.)
