The Influence Of Inter-hemispheric Interaction On Creative Scientific Problem Finding Ability

Creative scientific problem finding ability is an important part ofscientific creativity. The research of creativity brain mechanism is agrowing trend of the creativity research. A majority of researchesbelieve that right hemispheric(RH) plays an important role in thegeneration of individual creativity, but other researches hold thatthe production of creative thinking is the consequence of inter-hemispheric interaction(IHI). This research aims to assess therelationship between IHI level and CSPFA through comparing thesubjects’ performance on the CSPEA of different IHI levels.Experiment1: Adopting a mixed experiment design, which is2(mixed-hander, strong right-handed)×2(open-ended questions,closed-ended questions), to inspect the influence of handedness onCSPFA.Experiment2: Adopting a mixed experiment design, which is2(mixed-hander, strong right-handed)×2(Hemisphere: left,right)×7(Area， from AF to PO), to found the evidences from EEG thatinfluence of IHI on CSPFA.Experiment3: Adopting a mixed experiment design, which is2(mixed-hander, strong right-handed)×2(stroop test conditions: ongruent, in-congurent), to inspect the relationships of IHI, CSPFAand information inhibition ability.Experiment4: Adopting a mixed experiment design, which is2(question type：open-ended questions, closed-ended qestions)×3(eye movement level: contrast group, horizontal eye movementsgroup, vertical eye movements group), to investigate the influenceof eye movement on CSPFA.The result demonstrates:1) CSPFA of mixed-hander is much stronger, and is coincidentwith different questions.2) The frontal lobe in the right brain is significantly activatedwhen subject process the creativity task. And there exists neuro-Physiological evidence that creative thinking generation relies onIHI level.3) Subjects who have more IHI level express more impaired inthe stroop task.4) Both CSFP and Stroop task are influenced by IHI.5)The acceleration of CSPFA from bilateral eye movements isdifferent. Comparing with vertical eye movements, horizontal eyemovements are more conducive to the subjects’ performance intheir creative scientific problem finding task.The research conclusion: IHI level directly influences individualCSPEA. Horizontal eye movements can increase IHI level, andimprove the CSPFA after that.
