Recently, neuroscientific interest in altered states of consciousness (ASCs) has experienced a renaissance. In addition to pharmacological induction methods (IMs), there are numerous non-pharmacological IMs that can induce profound alterations in perception and thinking. Taxonomizing various IMs can offer a valuable framework for systematic investigations into the phenomenological, psychological,
... [Show full abstract] and physiological aspects of various ASCs. Most previous studies have dealt with only one IM and its correspondingly induced ASC. However, many ASC phenomena (e.g., out of body experiences) can be induced by multiple IMs. Comparing the different ASC phenomena induced by various IMs will help identify which conditions must be met to gain particular subjective experiences. The present work explores the benefits of using a big-data approach to taxonomize and visualize experimental IMs based on the induced ASCs.
