默认上下文2.0:二元随机变量系统

Contextuality-by-Default 2.0: Systems with Binary Random Variables

Ehtibar N. Dzhafarov, Janne V. Kujala

摘要:

本文概述了应用于二元随机变量有限系统的缺省上下文理论的新发展。原始理论的逻辑和原则保持不变,但随机变量系统的上下文性的定义现在基于在不同上下文中测量相同属性的变量的多重极大而不是最大耦合:如果这些多重极大耦合与共享上下文的随机变量的分布相容,则系统被认为是非上下文的。多重最大耦合是耦合的随机变量的任何子集(等价地,任何对)的最大耦合。论证了为什么这个修改后的理论是一个优越的推广传统的理解上下文量子力学。在循环系统的重要情况下,修改后的理论与以前的版本相吻合,其中包括在量子物理和行为科学中最深入研究的系统。

英文摘要:

The paper outlines a new development in the Contextuality-by-Default theory as applied to finite systems of binary random variables. The logic and principles of the original theory remain unchanged, but the definition of contextuality of a system of random variables is now based on multimaximal rather than maximal couplings of the variables that measure the same property in different contexts: a system is considered noncontextual if these multimaximal couplings are compatible with the distributions of the random variables sharing contexts. A multimaximal coupling is one that is a maximal coupling of any subset (equivalently, of any pair) of the random variables being coupled. Arguments are presented for why this modified theory is a superior generalization of the traditional understanding of contextuality in quantum mechanics. The modified theory coincides with the previous version in the important case of cyclic systems, which include the systems whose contextuality was most intensively studied in quantum physics and behavioral sciences.
