Quantum measurement theory is applied to quantum-like modeling of coherent generation of perceptions and emotions and generally for emotional coloring of conscious experiences. In quantum theory, a system should be separated from an observer. The brain performs self-measurements. To model them, we split the brain into two subsystems, unconsciousness and consciousness. They correspond to a system and an observer. The states of perceptions and emotions are described through the tensor product decomposition of the unconscious state space; similarly, there are two classes of observables, for conscious experiencing of perceptions and emotions, respectively. Emotional coloring is coupled to quantum contextuality: emotional observables determine contexts. Such contextualization reduces degeneration of unconscious states. The quantum-like approach should be distinguished from consideration of the genuine quantum physical processes in the brain (cf. Penrose and Hameroff). In our approach the brain is a macroscopic system which information processing can be described by the formalism of quantum theory. The paper is concluded with experimental test of contextual emotional coloring of conscious experiences based on Bell type inequalities which are treated in the contextual framework.
量子测量理论被应用于感知和情绪的相干产生的量子类似建模，以及一般的意识体验的情感色彩化。在量子理论中，系统应该与观察者分离。大脑进行自我测量。为了对其进行建模，我们将大脑分为两个子系统，无意识和意识。它们分别对应于系统和观察者。感知和情绪的状态通过无意识状态空间的张量积分解来描述；类似地，有两类可观察量，分别用于感知和情绪的意识体验。情感色彩化与量子语境相关联：情感可观察量决定语境。这种语境化减少了无意识状态的退化。这种类量子方法应该与考虑大脑中的真正量子物理过程（参见彭罗斯和哈梅罗夫）区分开来。在我们的方法中，大脑是一个可以用量子理论形式体系描述其信息处理的宏观系统。本文最后基于贝尔型不等式，对基于上下文的意识体验的情感色彩化进行了实验测试，这些不等式在上下文框架中进行了处理。
