The causal influence of conscious engagement on photonic behavior: A review of the mind-matter interaction.

The well-known, quantum physics "double-slit" experiment was the first demonstration of wave-particle duality of light-photons naturally behave like waves, but once they are registered by a conscious observer they switch to behaving like particles. In recent years, a new avenue of research has reported a psychophysical interaction occurring when focused attention was employed in the double-slit experiment. In this context, the act of focusing attention to photons passing through the double-slit appears to collapse their wave function thus causing a shift toward particle-like behavior reflected in a decreased intensity of wave interference.
