Penile tumescence and subjective sexual arousal were measured while 36
men viewed an erotic film segment and soon afterwards reproduced imag
inally the sexual events that had been depicted in the film. Film elic
ited higher levels of physiological and subjective sexual arousal than
was found for fantasy involving similar sexual content. Levels of sex
ual arousal during film and fantasy were more closely associated with
the extent the subjects had felt absorbed during erotic stimulation th
an with imagery scores on the Betts Questionnaire Upon Mental Imagery,
the Tellegen Absorption Scale, and the Imaginal Processes Inventory.
The subjects reported being more absorbed while watching the film than
during imaginal representation of the film content, and film remained
more sexually arousing than fantasy even when allowance was made for
differences in level of absorption between the two modalities. Further
directions for studying the basis for differences in sexual arousal b
etween film and fantasy are outlined.
