Audio Entrainment Effects Upon Executive Function

Abstract

The scientific study of perceptual consciousness, as the emergent property of cognitive processes, out of the ‘dynamic unconscious’ of neurological functions has undergone significant development in the realm of cognitive neuroscience over the past three decades [12]. Whereas our conscious experience of perception was once thought inaccessible to the empirical sciences, contemporary neuropsychological research conceptualises it as a structured, organised, dynamic, and mechanistically causated phenomenon grounded in coordinated neural synaptic system feedback loop oscillations organising themselves into a mental representation of our conscious physical experience.

Modern theories in neuroscience, such as Global Workspace Theory, Integrated Information Theory, and hierarchical predictive-processing architectures, together state that conscious experience arises not from the isolated function of localised neural activity, but from temporally organised, large-scale patterns of coherent cognitive association distributed across the central nervous system linking intracausal node-networks intercausally across the whole brain. These systems engineering models contend that the brain’s oscillatory electromagnetic feedback loop rhythms form the coherence of a temporal scaffolding across which perception, cognition, and self awareness are intertwined. As such, psychological therapeutic interventions which are capable of modulating synaptic oscillatory coherence and unity offer psychological scientists a unique gateway through which to experimentally investigate the alignments of our cognitive neural information processing architecture underlying our emergent epiphenomenal conscious state.

Within this neurocognitive psychophysiological context, auditory entrainment of two divergent frequency stimuli following their transduction into electrochemical energy into a recombined synthesised frequency as an auditory perception, specifically engendered through sound-engineered binaural beat meditation commercial audio productions, is now receiving increasing scientific interest by the mainstream psychological community. When two different frequencies of divergent frequencies are presented dichotically, the brain generates a perceptual experienced wavelength “beat” which is equal to the frequency difference. This phenomenon of experienced perceptual consciousness was first described by Gerald Oster (1973); it reflected the neural computations processed in the superior olivary complex that produces frequency-following neurological responses that are detectable across thalamocortical circuits higher up in the neural information processing architecture of the human brain.

Contemporary research as such appears to demonstrate that binaural beats can modify the brainwave oscillatory power, coherence, and phase synchronisation in specific targeted frequency bands within the rhinal cortex, medial temporal lobes, and hippocampus [11]. These findings therefore indicate that auditory entrainment constitutes a non-invasive method of investigating consciousness, perception, and state-of-mind dynamics through influencing the higher-order temporal areas of neural information processing structural architecture [21].

However, the foundations of the empirical research into binaural beat phenomena still remain largely fragmented, with significant variability in the obtained results due to inconsistent methodological protocols or experimental control over interactive factor variables (Orozco-Perez, Dumas and Saporta, 2020). Many studies also appear to lack sufficient theoretical grounding to make significant advances to the field, or fail to incorporate autonomic arousal markers, such as heart rate variability and perspiration, that are essential to evaluating changes from the baseline cognitive performance and physiological arousal [32].
