Overview #
This article examines how mind-body medicine—especially biofeedback and neurofeedback—offers a practical framework for understanding the long-standing philosophical “mind-body problem.” Frederick argues that physiological monitoring and self-regulation training provide an evidence-based pathway to study how conscious and subconscious processes interact.
Foundations of the Mind-Body Problem #
The paper outlines traditional approaches to mind-body dualism and highlights why correlation, sufficiency, and necessity in neuroscience still fail to fully explain subjective experience (“qualia”).
The author notes that even if specific EEG patterns correlate with perceptual experiences such as “yellow,” this does not clarify why neural activity produces qualitative experience.
Biofeedback as a Framework for Mind-Body Research #
Frederick emphasizes the Psychophysiological Principle (Green & Green, 1977): changes in physiological state correspond with changes in mental-emotional state, and vice versa. Biofeedback, by enabling voluntary control of internal states, provides a research method to study this bidirectional relationship.
The article proposes that mapping which physiological processes are consciously discriminable or voluntarily controllable may illuminate the “boundary conditions” between conscious and subconscious systems. Frederick describes this as a possible “mind-brain barrier.”
Qualia, Consciousness, and Cognitive Constraints #
Drawing on theories from Ramachandran & Hirstein and Baars, Frederick outlines three properties of qualia—irrevocability, flexible output, and maintenance in short-term memory—and connects these to the limited capacity and serial nature of conscious processing.
He argues that these constraints create evolutionary pressures that shape what information becomes consciously accessible.
EEG State Discrimination Research #
The article summarizes Frederick’s own empirical work on EEG alpha-state discrimination, expanding on Kamiya’s foundational research:
-
Participants: 22 adults (ages 18–55).
-
Method: Participants identified “high” versus “low” alpha states using tones triggered by EEG alpha power percentile thresholds.
-
Findings:
-
11 subjects exceeded discrimination criterion (p < .01).
-
Performance improved across sessions (R² = 0.736).
-
Higher accuracy occurred for extreme (“very low” and “very high”) alpha percentiles (ANOVA F=3.99; p=.004).
-
Longer intervals improved accuracy (71% for 4-second intervals vs. 63% for 1-second).
-
-
Implication: Results suggest the existence of a measurable introspective sensory modality for perceiving brain electrical states.
Implications for Future Mind-Body Research #
Frederick proposes expanded psychophysics studies on other EEG constructs (coherence, phase, ERPs, frequency peaks). These would help clarify how discrimination and volitional control interact—potentially informing more targeted clinical interventions.
