Consciousness is not reality itself but a mechanism for subjective experience (Perceptual Reality Monitoring).
A centrist view integrating extreme local and global approaches is needed for understanding consciousness.
Challenging the global workspace theory, Perceptual Reality Monitoring offers a centralized perspective on conscious experience.
Deep dives
Low's Proposal on Consciousness and Reality Monitoring
Low proposes that reality monitoring is the mechanism by which subjective experience is obtained, emphasizing that consciousness is not reality itself, but the mechanism through which subjective experience is obtained. He suggests that the brain's mechanistic process responsible for subjective experience turns out to be the circuit for reality monitoring, introducing the Perceptual Reality Monitoring theory.
Critique of Existing Consciousness Theories
Low criticizes the abundance of consciousness theories, targeting the inflating importance of certain theories championed by established figures. He contrasts extreme local and global approaches to consciousness, highlighting the need for a more centrist view that integrates both perspectives. Low's Perceptual Reality Monitoring theory stands as an example of a higher-order theory that involves hierarchical information processing.
Challenges with Global Workspace Theory
Low challenges the global workspace theory, stating that it fails to account for all experimental data and presents a more centralized view through the Perceptual Reality Monitoring theory. He suggests that the theory's inability to explain the qualitative nature of conscious experience limits its comprehensive understanding.
Critical Examination of Experimental Confounds
Low highlights the significance of recognizing and addressing experimental confounders in consciousness studies, emphasizing the need for converging evidence from various experimental approaches. He presents real-life examples to illustrate the impact of confounders on scientific interpretations.
Functionality and Embodied Cognition Concerns
Low's functionalist approach to consciousness raises questions regarding the role of embodied cognition and emotions in subjective experience. He acknowledges the need for a broader integration of findings from outside the specific field of consciousness studies to enrich theories and understandings of consciousness.
This month's episode of Brain Science is an interview with Hakwan Lau, author of In Consciousness we Trust: The Cognitive Neuroscience of Subjective Experience. Lau talks about shortcomings in current theories about how the brain generates consciousness, but he also introduces something he calls perceptual reality monitoring.
Although this is a somewhat technical discussion it is accessible to listeners who are new to the neuroscience of consciousness.
