The Neural Processing Of Solving The Semantic Creative Problems Spontaneously

Looking back in history, progress of The development of human society is inseparable from the creation, the creation is the power source of progress and development of human society since ancient times for thousands of years has been attracting many researchers’ attention. However, human studies on the creation of a broad array of activities for the creation of what is produced, what are the basic conditions produced, until now still not very clear theory can explain. Brain, humans most mysterious "black box", which is considered the highest command of human behavior but also gave birth to the creation of the parent. There is no doubt that studying the brain activity of creative thinking processing mechanism, unveiled Creative Thinking of how it works in the brain with create a deeper understanding of the activity has an irreplaceable role.Previous studies on creative problem solving particular semantic class creative problem, usually presents clues induce subjects to generate ideas to solve the problem of paradigm. Specific to the type of insight semantic issues, experiments typically exhibit cues or direct answers to questions presented by this way catalytic insight, thereby insight research process. However, this induced paradigm, and can not restore the real-life real creative problem solving process, this paradigm is more of a process of comprehension, using spontaneous paradigm will more fit real problem solving scenarios.Although spontaneous paradigm in line with the nature of creativity, but its problem resolution time is longer, the probability of successful resolution of the lower limit the experimental study of the paradigm.Previous studies use Chinese Xichouyu as insight problem, since it was difficult to solve by spontaneous, studies are used to induce paradigm. We analysis the generation of Chinese Xiehouyu, we develop the reverse Chinese Xiehouyu puzzles, by actual measurement to verify the results. The results show that learning by example, reverse Chinese Xiehouyu puzzle can be solved in the form of self-test, within a specified period of time to a certain novel rate (based on material properties, there is no right or wrong answers) solved.Previous studies have raised the neural mechanisms of semantic model of creative issues, including frontal and temporal lobe, anterior cingulate cortex and the hippocampus, including settlement, in the first study, we use the EEG methods to record the waveform at the time of two seconds before the subjects create novel answer, by dipole localization analysis: in problems successfully resolved before 2s right hemisphere frontal and temporal region has more dipole distribution, it showed frontal and temporal region Unicom strong. And when the time is extended to the successful resolution of the problem before the Is, the dipole distribution is mainly located in the frontal region,indicating that it has successfully generated new links, participants have the answer, do not need to adjust by the frontal temporal lobe on both sides. Especially the right temporal lobe is responsible for processing non-highlight semantic information. These changes left hemisphere process does not exist, when the same question to unusual means to resolve when both sides do not change and the degree of difference on the way there. The results support the information selection part of the model.In the second study, fMRI technique was used. In the experimental design, the dimension of adaptability was introduced to the characteristics of creative thinking, and the experiment was divided into four categories according to the self-evaluation results.The results of the group analysis showed that the brain exhibited higher activation in the bilateral prefrontal cortex, left fusiform gyrus and right cingulate gyrus in the novel conditions than in the non-novel conditions.
