Theories of consciousness explore how and why we experience awareness and subjective thoughts. One prominent theory is the Global Workspace Theory, which suggests that consciousness arises when information is broadcasted to various cognitive processes, allowing for integration and decision-making. Another significant perspective is the Integrated Information Theory, which posits that consciousness corresponds to the level of information integration within a system. According to this theory, a system with high integration can generate richer conscious experiences, while simpler systems have limited awareness. These theories aim to explain the complex nature of human consciousness.
