Forty-eight adult male volunteers attempted to suppress sexual arousal while viewing a sexually explicit videotape and generate an arousal response while viewing a neutral videotape. Attendance to the stimuli was assured by requiring subjects to provide an ongoing verbal description of the videotape they were viewing. While significant effects in controlling arousal were obtained, the degree of subject success varied as a function of the criteria used for evaluating outcome. The most conservative analysis, a simultaneous discriminant analysis procedure comparing subjects penile plethysmographic responses across the entire 3 min of each condition, revealed that in no case was a subject able to produce a pattern of sexual response that was misclassified as the condition he was attempting to emulate. Results support the value of requiring attendance to experimental stimuli and of analyzing trends/patterns of arousal across an entire experimental period in identifying attempts to "fake" sexual preferences. Theoretical and clinical implications of these findings are discussed.
48名成年男性志愿者在观看色情录像带时试图抑制性唤起，并在观看中性录像带时产生唤起反应。通过要求受试者对正在观看的录像带进行持续的口头描述来确保他们对刺激的关注。虽然在控制唤起方面取得了显著效果，但受试者的成功程度因用于评估结果的标准而异。最保守的分析是一种同时判别分析程序，比较每个条件下整个3分钟内受试者的阴茎体积描记反应，结果显示，在任何情况下，受试者都无法产生一种被误分类为他试图模仿的条件的性反应模式。结果支持了在识别“伪装”性偏好的尝试时，要求关注实验刺激以及分析整个实验期间唤起趋势/模式的价值。讨论了这些发现的理论和临床意义。
