Kolb provided us with insight into the different types of personality. He created a four-quadrant model as well; including ways we sense, perceive and respond to external stimuli. He thought there were Thinkers, Watchers, Feelers and Doers. In my psych class I ask the class to write down which combination(s) they are and then do an inventory to see if there responses match their notions of their personality. It got me thinking, how much of what theorists assign to the left brain or right brain might be more of a process of the mind i.e. the development of the personality and how you approach problem solving?
