===Psychedelic effects can be produced by sensory overload in about 40% of normal subjects. Subjects tend to experience time as "speeded up" in sensory overload and "slowed down" in sensory deprivation as compared to the normal control condition===

"The potential for SD[sensory deprivation] to produce alterations in consciousness (eg, greater visual imagery, hallucinations, time distortion, etc) is well recognized, but to date little is experimentally known about the ability for SO to do likewise. So far, with the experimental paradigm employed, we have found in fact that SO[sensory overload] may produce mild to profound distortions in reality testing or "psychedelic" effects in about 40% of the normal subjects. For purposes of illustration, several verbatim excerpts from interviews conducted immediately after exposure to SO are presented."<ref>Ludwig, A. M. (1971).
