I. Kirsch et al., A SPECTRAL-ANALYSIS OF COGNITIVE AND PERSONALITY-VARIABLES IN HYPNOSIS - EMPIRICAL DISCONFIRMATION OF THE 2-FACTOR MODEL OF HYPNOTIC RESPONDING, Journal of personality and social psychology, 69(1), 1995, pp. 167-175
The two-factor model of hypnotic responding posits that ability or tra
it variables are more important than contextual variables in producing
responses to difficult hypnotic suggestions, whereas contextual varia
bles such as attitudes and expectancies are more important than trait
variables in predicting responses to easier suggestions. In three sepa
rate data sets, responses to suggestions of varying difficulty were co
rrelated with absorption, fantasy proneness, dissociation, attitudes t
oward hypnosis, and hypnotic response expectancy. Although the results
of these analyses were not consistent across data sets, all significa
nt findings were in the opposite direction of that predicted by two-fa
ctor theorists. In general, expectancy was the strongest correlate of
hypnotic response, especially for highly responsive participants and f
or difficult suggestions. It is concluded that despite the attractiven
ess of the two-factor model, repeated attempts to replicate its empiri
cal base have been unsuccessful.
