The two-factor model of hypnotic responding posits that ability or trait variables are more important than contextual variables in producing responses to difficult hypnotic suggestions, whereas contextual variables such as attitudes and expectancies are more important than trait variables in predicting responses to easier suggestions. In three separate data sets, responses to suggestions of varying difficulty were correlated with absorption, fantasy proneness, dissociation, attitudes toward hypnosis, and hypnotic response expectancy. Although the results of these analyses were not consistent across data sets, all significant findings were in the opposite direction of that predicted by twofactor theorists. In general, expectancy was the strongest correlate of hypnotic response, especially for highly responsive participants and for difficult suggestions. It is concluded that despite the attractiveness of the two-factor model, repeated attempts to replicate its empirical base have been unsuccessful.
Students were given 1 of 2 versions of the Carleton University Responsiveness to Suggestion Scale (CURSS): (a) the original version, which contains instructions to intentionally imagine goal-directed fantasies, and (b) a modified version, in which instructions for suggestion-related imagery were deleted. Participants were asked to report their goal-directed fantasies and to indicate whether these occurred spontaneously or were generated intentionally. They were also asked whether they had tried intentionally to generate the suggested experience and to indicate whether they had believed that the suggested states of affairs were real (e.g., whether they thought a hallucinated cat really existed). The deletion of instructions for goal-related imagery significantly increased responsiveness to CURSS suggestions. Spontaneous goal-directed imagery was significantly correlated with behavioral response, but intentional imagery was not. Most successful responders tried to generate suggested experiences intentionally, indicated that they could have resisted challenge suggestions if they really wanted to, and reported believing in the reality of suggested ideomotor and challenge experiences but not of cognitive suggestions. Voluntary attempts to generate suggested experiences were correlated with subjective responding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
