This study is investigating the effects of hetero-hypnosis and psychological skills according to how they compare when measured in terms of performance in a computer game called the Stroop task. The study is being conducted as part of my (Adam Eason) Bournemouth University research and it is hoped that the findings will be published and as a consequence help to contribute to potential clinical applications of hypnosis, as well as adding to our growing knowledge of both hypnosis and self-hypnosis.
