Last night, I decided to catch a much talked about TED talk by Dr Jill Bolte Taylor and boy was I blown away! In the video, the celebrity neuro-anatomist described her experiences when she suffered a stroke on her left brain and painted a beautiful and vivid picture of that somewhat transcendental encounter. From that incident, she was able to isolate the functions of both brains via a first person perspective, showing how the two cerebral hemispheres (connected by a bunch of tissue called the corpus callosum) interact and work with each other.
Convergent thinking is the one that is more frequently employed at work, in schools, and often at home. It is a form of thinking employing deductive reasoning, which looks at bringing together information that is focussed on solving a problem. Often, convergent thinking is useful for situations where a single correct solution exists. Such modes of thinking are commonly employed in scientific, engineering, financial and other analytical fields (like much of Police work).
