Convergent thinking and 2 bands. The large increase in amplitude and coherence indicates a close synchronization between both hemispheres in the brain. The successful generation of the hypothesis during divergent thinking performance seems to induce positive emotions which, in part, can be due to the increase of complexity and performance measures of creative thinking, Psycho-inter-hemispheric coherence. Finally, the obtained dominance of the right hemisphere and ‘the cognitive axis’, the coupling of the left occipital – right frontal in contrast to the right occipital – left frontal ‘axis’ characterizing analytic thinking, may reflect the EEG pattern of the unconscious mental processing during successful
Vertical thinking of validity. Furthermore, when considering the linear approach, the solutions generated from such methods of thinking are often neutral, which is again preferred when bearing in mind an academic background. Moreover, the risks of this method of thinking is much lower than that of lateral thinking. Backed by an existing knowledge base, solutions generated using this method are more well informed. Due to the perfectionism generally involved when creating a solution, there is often a lack of originality in the answers. Referring to this point, most innovative ideas were not created through vertical thinking as ideas generated this can be
