“…Although the PCI-HAP does not include a measure of hypnotizability like the total scale scores from the HGSHS or the SHSS:C, it does generate a self-report measure of hypnotic depth, the selfreported Hypnotic Depth (srHD) score. This score has been found to correlate with total HGSHS scores (Barnes, Lynn, & Pekala, 2009;Pekala & Kumar, 1984, 1987 and the SHSS:C (Hand, Pekala, & Kumar, 1995).…”

This preliminary study explored the relationship between imagery vividness before and during a hypnotic phenomenological assessment procedure, the Phenomenology of Consciousness Inventory-Hypnotic Assessment Procedure (PCI-HAP), while also assessing trance (hypnoidal) state effects and several other variables. The PCI-HAP allows the assessment of trance state effects associated with hypnotism to be quantified and statistically assessed. The 102 subjects completed the PCI-HAP along with several other questionnaire items. Correlational and regression analyses suggested that imagery vividness during hypnotism (hypnotic imagoic suggestibility) was predicted by combined imagery vividness before hypnotism and trance (altered) state effects during hypnotism. When measuring several additional variables, imagery vividness during hypnotism was found to be a function of self-reported hypnotic depth and additional other variables. The usefulness of these results for better understanding imagery vividness before and during hypnotism is discussed.

“…For example, research measuring involuntariness during response to suggestions in a standardized scale showed that as many as 20% of responses are executed in a completely voluntary manner (Bowers, Laurence, & Hart, 1988). Thus, hypnotic suggestibility scales probably index a mixture of involuntary and compliant responses that cannot be reliably distinguished solely on the basis of behavioral indices (see also Balthazard & Woody, 1992;Barnes, Lynn, & Pekala, 2009;Kirsch, Silva, Comey, & Reed, 1995). Second, only minimal attention has been devoted to experiential responses to hypnotic suggestions in the wake of an induction.…”

Nuances and Uncertainties Regarding Hypnotic Inductions: Toward a Theoretically Informed Praxis

Although most definitions of hypnosis consider inductions as the initial stage in a hypnosis protocol, knowledge of inductions remains poor and uninformed by recent developments in theory and research. It is frequently argued that inductions play a critical role in hypnotic responding or, by contrast, are largely interchangeable and unimportant. Drawing on the literature on suggestibility, spontaneous phenomenology, neurophysiology, and cognition, this article argues that the value of inductions, as well as the potential value of inductions, is more nuanced and uncertain. Certain components of standard inductions appear to be efficacious in enhancing suggestibility, whereas others do not have any clear benefits. The impact of inductions on suggestibility seems to vary across suggestions and modes of assessment with the sources of this variability being unknown. Considering these effects, and the broader impact of inductions on spontaneous conscious states and cognition, through the lens of heterogeneity in high hypnotic suggestibility and componential models of hypnotic suggestibility may offer novel research avenues in this area. The article concludes by arguing for the practical and theory-driven optimization of inductions.
