시각적 자극에 대한 언어 선택의 양자성 판별

Abstract

의사 결정 과정을 연구하는 방법에는 일반적으로 두 가지 방법이 있다. 하나는 고전 확률론에 근거한 연구이며 다른 하나는 양자 확률론에 근거한 연구이다. 이 두 확률론은 몇몇 기본 특성에서는 동일하지만, 핵심이 되는 부분에서는 차이가 있다. 고전 확률론은 확률의 합법칙을 따르는 반면, 양자 확률론은 그렇지 않다. 본 연구에서는 양자 확률론에서는 합법칙이 성립하지 않는다는 점에 착안해 의사 결정의 하나인 시각적 자극에 의한 언어 선택에 있어 양자성 여부를 조사하였다. 시각적 언어 선택에 있어 양자성 여부 연구를 위해 핵심이 되는 두 선택 사이의 독립성과 간섭성을 조사하였다. 설문조사를 통해 두 선택사이의 독립성과 간섭성을 조사한 결과 확률의 합법칙을 따르지 않는 결과를 얻었다. 이는 고전적인 확률론으로는 설명할 수 없으며 양자 확률론을 통해서 설명 가능하다는 결론에 도달하였다.| There are two general probabilistic method to study decision making process: one is based on classical probabilistic theory and another is based on quantum probabilitic theory. These two probabilisitic theory shares some fundamental ideas, but they are also different in some key properties. Classical probabilisitic theory obeys the law of total probability but quantum theory does not. Based on the difference between classical and quantum probability, we examine if any quantum coherence is exposed in word choice stimulated by visual image. In order to study the quantum coherence in word choice, we conduct a experiment and examine independence and quantum interference between two choices. We obtain cases in which the law of total probability is violated. We conclude that classical probability theory cannot explain this violation but quantum probability theory provide a reliable and powerful account of the process of word choice.; There are two general probabilistic method to study decision making process: one is based on classical probabilistic theory and another is based on quantum probabilitic theory.
