Psi是不可能用現有的科學經驗解釋的科學研究。Psi包括超感知覺和念力,超感知覺泛指訊息的獲得不是用經由傳統的視覺、聽覺、嗅覺、觸覺和聽覺;念力指似乎只以意志力,不碰觸環境情況下而影響環境。Psi的研究可能提供我們了解心智與環境的關係及相互作用。很多研究指出Psi可能存在,但仍然有些學者不認同這個觀點的。七個因素可能與Psi現象相關,包括:年齡、放鬆、情緒反應、實驗者作用、高的磁場、個性和信仰。然而,這個新的科學被質疑其研究結果有瑕疵及研究結果可否被不同研究者複製等問題。目前需要更多的研究在嚴謹的方法學下來探討與測試Psi的訓練模式。
Psi is the scientific study of experiences that cannot be explained by the existing science. Psi is a general term including both extrasensory perception (ESP) and psychokinesis (PK). ESP is a general term used for information acquisition other than by conventional sensory processes of sight, sound, taste, touch and hearing; PK is an ability that influences the environment seemingly by intention or other mental activity alone without motoric intervention. The investigation of Psi might contribute to our knowledge of brain-environment relationships or interaction. Many researchers have carried out a large number of studies examining the possible existence of Psi with positive results, though some researchers do not agree with this point. Seven factors seemingly have a possible link with Psi performance are: aging, relaxation, emotional response, experimenter effects, magnetic field, personality and belief. Notwithstanding the above, this new scientific subject is confronted with the issue of fraud and replicability by different researchers. Studies with a testable model under well-controlled methodology for the Psi training process are wanted.
