A Double-Slit Diffraction Experiment to Investigate Claims of Consciousness-Related Anomalies

An experiment in which participants were asked to reduce the fringe contrast in a Young's double-slit interference pattern has been conducted independently at two laboratories using the same apparatus. Participants at York University were explicitly invited to exert their intentionality either to direct the photon flux preferentially through one path or the other, or to obtain spatial information about the division of the flux. Participants at Princeton University were invited simply to reduce the fringe contrast by any strategy they wished. Results from both laboratories (Z = -0.481 and Z = 1.654 respectively) are discussed along with a description of earlier efforts to frame this experiment as a test of an extra-sensory channel for the acquisition of information.
