Summary
Virtual Reality (VR) offers a safe avenue to explore psychedelic-like effects, significantly boosting Cognitive Flexibility crucial for Creativity. This Cognitive Psychology approach suggests VR-induced changes in Perception and sensory input—relevant to Olfactory and Sensory Function Studies—can optimize how our Cognition balances expectations. Enhancing Cognitive Flexibility and Executive functions through such Psychedelics and Drug Studies-inspired methods could be vital for maintaining robust brain health, particularly in aging, preventing declines seen in conditions like Mild Cognitive Impairment, and potentially enriching Aesthetic Perception and Analysis.
Abstract
Recent research has investigated the potential of psychedelic substances in treating various neurological and psychiatric disorders. In particular, there has been a growth in studies concerning the intersection of psychedelics, Virtual Reality (VR), and Cognitive Flexibility (CF). Indeed, the use of immersive technology allows the simulation of the perceptual and cognitive effects of psychedelic substances without the potential risks associated with them. CF is strongly associated with creative cognition, a complex cognitive mechanism involved in creative thinking and associated with the prefrontal cortex and the neural networks supporting executive functions, memory, attention, and spontaneous modes of thought. The Bayesian brain approach, which is rooted in predictive coding, has emerged as a promising framework for understanding the effects of psychedelic hallucinations on cognitive functioning. Psychedelic substances may enhance creativity by inducing a state of CF, allowing for a wider range of associations and possibilities to be explored and increasing openness to experience. A decline in cognitive abilities, including creative processing and divergent thinking, is observed during the aging process. In particular, studies on Mild Cognitive Impairment (MCI) show poorer performance in executive functions, including CF. The present paper suggests that psychedelic hallucinations induced by VR may help optimize the balance between top-down expectations and bottom-up sensory information. Therefore, enhanced CF and creativity may be crucial during the aging process for maintaining cognitive functions and preventing pathological conditions.
