Parapsychology

Derived from the term 'paranormal', parapsychology is the science that lies beside or beyond psychology; the field of psychology which studies those unique experiences and unknown capabilities of the human mind that suggest consciousness is capable of interacting with the physical world in ways not yet recognized by science, but not beyond science's ability to investigate.  


Two types of parapsychological phenomena have been described.   The first and less common is pyschokinesis (PK) which is the direct influence of the human mind on the environment.   In rare cases, this may involve obvious movement of objects, however most contemporary research studies PK influences on atomic or electronic processes.
