Hypnotizability refers to "An individual's ability to experience suggested alterations in physiology, sensations, emotions, thoughts, or behavior during hypnosis" (Elkins, Barabasz, Council, & Spiegel, 2015). Research has demonstrated that most people are hypnotizable and that individual differences in hypnotizability exist. In recent years, there have been important advances on perspectives and new, well-validated scales for measurement that seek to improve on older measurement instruments. Emerging research has sought to address questions such as: Is hypnotizability a natural human ability independent from formal hypnotic inductions?; Are multi-component theories most accurate to account for differences in hypnotizability?; What can we learn from a critical review of older measures of hypnotic susceptibility?; Can hypnotizability assessment be accomplished by phone?; What is being found from current study of the Hypnotic Induction Profile?; Can assessment of hypnotizability have therapeutic benefits?; Does comparison of older and newer measures of hypnotizability such as the Elkins Hypnotizability Scale point to a new "gold standard" based on contemporary research? This special issue of the IJCEH provides insights into these important questions.
