The exclusionary approach to consciousness

Area of Science:

• Neuroscience
• Philosophy of Mind
• Cognitive Science

Background:

• The standard method for identifying neural correlates of consciousness (NCCs) compares brain activity during conscious versus unconscious trials.
• This standard approach faces challenges due to difficulties in defining and measuring consciousness consistently.
• Lack of consensus hinders the establishment of definitive criteria for consciousness theories.

Purpose of the Study:

• To propose an alternative methodology for NCC research: the exclusionary approach.
• To leverage reliable subjective reports under normal conditions to refine NCC identification.
• To offer a less contentious method for establishing hard criteria for consciousness theories.

Main Methods:

• The exclusionary approach assesses consciousness stability across trials while varying other factors (reports, tasks, attention).
• It contrasts neural activity under stable consciousness conditions to exclude non-NCCs.
• This method can utilize existing research, particularly studies on confounding factors.

Main Results:

• The exclusionary approach yields less contentious results compared to the standard identification method.
• It provides a framework for excluding neural activity not associated with consciousness.
• This method establishes more robust criteria for evaluating theories of consciousness.

Conclusions:

• The exclusionary approach offers a complementary strategy to the standard identification of NCCs.
• It enhances the rigor of consciousness research by providing exclusionary criteria.
• This methodology can be integrated with existing paradigms to advance the field.
