Schweiger Gallo, I., Pfau, F.,& Gollwitzer, P. M. (2012). Furnishing hypnotic instructions with implementation intentions enhances hypnotic responsiveness. Consciousness and Cognition, 21, 1023-1030.
Forming implementation intentions has been consistently shown to be a powerful selfregulatory strategy. As the self-regulation of thoughts is important for the experience of involuntariness in the hypnotic context, investigating the effectiveness of implementation intentions on the suppression of thoughts was the focus of the present study. Participants were randomly assigned to one of four conditions (hypnotic instruction plus implementation intention, hypnotic instruction, implementation intention, and control condition). Results showed that participants who received information included in the ‘‘Carleton Skill Training Program’’ and in addition formed implementation intentions improved their hypnotic responsiveness as compared to all of the other three groups on measures of objective responding and involuntary responding. Thus, in line with the nonstate or cognitive social– psychological view of hypnosis stating that an individual’s hypnotic suggestibility is not dispositional but modifiable, our results suggest that hypnotic responsiveness can be heightened by furnishing hypnotic instructions withad hocimplementation intentions.
