"This experiment occurred during the context of an orgasm study. All participants described themselves as being “consistently highly orgasmic” during study enrollment. As there has been support in the literature for a correlation between orgasm reliability and higher hypnotic suggestibility(Bridges, et al., 1985), and imagery ability (Harris et al., 1980), the degree of suggestibility of these participants may potentially have biased the results toward more robust imagery activations than expected. This may have contributed to the lack of robustness of the brain response to the physical stimulation conditions by having the explicit modeling be too suggestive of the actual physical stimulation."
