Experimental Psychology

Experimental psychology studies mental processes, perception, memory, reasoning and emotional response, through controlled laboratory measurement rather than introspection or philosophical argument alone. Wilhelm Wundt founded the discipline in 1879 by establishing the first laboratory dedicated to psychological experimentation at the University of Leipzig, where he and his students used reaction time measurement and controlled sensory stimuli to study mental processes as something that could be timed and manipulated like any other measurable phenomenon, rather than only described.

The discipline's methods have since been turned directly on religious experience itself, on the neurological and psychological correlates of prayer, meditation and reported mystical states, and on the cognitive mechanisms that make supernatural belief easy to form and hard to dislodge. That work does not settle whether a reported religious experience corresponds to anything beyond the mind that had it, a question outside experimental psychology's competence, but it does give the atlas a controlled, replicable account of what is measurably happening in a believer's mind and body during practices that traditions themselves describe only in devotional or doctrinal language.
