This paper reviews studies that have explored methods that might enhance the operation of psychokinesis. The studies are di­vided into six main categories: (a) hypnosis, (b) yoga and meditation, (c) relaxation, (d) feedback, (e) negative reinforcement and punish­ment, and (f) visual imagery. A distinction is made between training studies and studies conducted to explore the effectiveness of certain methods. Most of the studies investigated methods that might facilitate the operation of PK on a single occasion. The designs of the studies are described, and their results are presented and discussed. Several improvements and suggestions are considered for future re­search into methods of enhancing and potentially training PK
