本研究旨在探討人類大腦對事物之喜好是否有其特定區域與其腦波反應，研究對象以電玩成癮者與非電玩成癮者進行比較，藉由 fMRI 與 EEG 等大腦偵測儀器，觀察受測者在接受到喜好、中性與不喜好三類型圖片刺激後大腦呈現之反應，在 fMRI 實驗中，共有22位受測者（11位電玩成癮者與11位非電玩成癮者），發現到電玩成癮組與非電玩成癮組在接受到喜好、中性、不喜好圖片刺激時在大腦的頂葉、顳葉、枕葉均有不同活化反應，並發現電玩成癮組比起非電玩成癮組在接受電玩圖片刺激時，腦部位置：右側中央前回及額下回，左海馬回，左額中回，左額下回，右頂葉腦下回，右額下回， 右側楔葉等有較為顯著的活化反應，隨後，受測者進行 EEG相同實驗(刺激間隔不同)，結果發現，在大腦皮質接近 fMRI活化區域之腦波，電玩成癮者與非電玩成癮者也有顯著不同，依此結果，我們進一步以類神經網路建立電玩成癮與非成癮者腦波模式，有效的將兩類受測者分辨出來，此種結合不同偵測技術、統計與類神經網路等技術於一體，深具創新性、學術價值與實用性，此種研究技術與成果，對教育、醫學、與社會治安的研究，將有極重要貢獻。

This study was designed to investigate whether there is a particular area of their brain with Brainwave reaction is relation to the human brain for preference. Study were compared with video game addiction to gaming and non-addicts. By some brain detection devices such as fMRI and EEG, observing the reaction of the subjects’ brain after receiving the three types of picture, like, Neutral, non-like. In the fMRI experiment, there were 22 subjects including 11 game addicts and 11 non-addicts. It shows that Experiment Group and Control Group both display different activated reaction in Frontal lobe, Parietal lobe, Occipital lobe and Temporal lobe when their brain receive the picture stimulus. Specially, Right precentral gyrus and inferior frontal gyrus, Left hippocampal gyrus, Left middle frontal gyrus, Left inferior frontal gyrus, Right inferior parietal gyrus, Right inferior frontal gyrus, Right cuneus in the game addicts group have more distinct reaction then non-addicts group.
After that, the subjects participate in the same experiment with EEG(with different stimulus interval). The result shows the brainwave in fRMI area nearby the cerebral cortex also contains distinct difference in both group. By above, we further establish brainwave patterns with game addicts and non-addicts with neural network. Distinguish the two types of subjects effectively. The research combines many detection technique, statistic and neural network. There are in rich of innovation, academic value and practicability. It contributes to the research of the education, medical science and social security In the future.
