Y_4_15 — Sensory Overload and Information Flooding: Excess as Altered State
Sensory overload — the state that arises when sensory input exceeds the brain's capacity for orderly processing — represents the mirror image of sensory deprivation as a pathway to altered consciousness. While deprivatio
Y_4_12 — Psychosomatic Phenomena and the Placebo Effect
