Eight adult male subjects participated in a counterbalanced, repeated-measures design to determine the relative efficacy of color and black-and-white visual sexual stimuli in eliciting sexual arousal, as objectively measured by a mercury-in-rubber strain gauge transducer. There were no consistent or significant differences in either the intensity or the pattern of penile responding during color and black-and-white presentations of the same film.
