The cognitive processing of sexual and non-sexual pictorial stimuli was examined to see whether picture rating and recognition tasks have potential utility as a means of assessing levels of sexual desire. Previous research has revealed slower responding to sexual compared to neutral semantic cues in persons with lower self-reported sexual desire. The present study investigated whether sexual pictorial cues evoked a similarly slower responding in people reporting low sexual desire compared to other individuals. A total of 136 participants completed two self-report measures of sexual desire (the Hurlbert Index of Sexual Desire and the Sexual Desire Inventory) before carrying out tasks involving affective ratings and recognition memory for pictorial stimuli. Participants were classified into relatively low, average, and higher groups on the basis of their scores on the desire measures. The stimuli were selected from the International Affective Picture System, and the tasks included (1) rating the valence, arousal, and sense of dominance or control for each picture, (2) recognition of previously seen images, and (3) a second rating of pictures viewed earlier. Level of sexual desire did not influence responding in the male participants. Female participants with lower sexual desire rated sexual images less pleasant and less arousing than the other participants, and completed picture recognition tasks more quickly. Sexual desire levels significantly influenced the interest ratings women gave to sexual pictures. We also found sexual content induced delays. These delays were not significantly different among desire groups. The variation in responding linked to levels of sexual desire in women suggests that more investigation of this methodology in a clinically diagnosed population might contribute to an understanding of low desire, and help design interventions addressing distress due to lack of sexual desire.
研究人员对性和非性图片刺激的认知加工进行了考察,以探究图片评分和识别任务作为评估性欲水平手段的潜在效用。先前的研究表明,自我报告性欲较低的人对性语义线索的反应比对中性语义线索的反应更慢。本研究调查了与其他人相比,性图片线索是否会在报告低性欲的人群中引发类似的较慢反应。共有136名参与者在进行涉及对图片刺激的情感评分和识别记忆的任务之前,完成了两项性欲的自我报告测量(赫尔伯特性欲指数和性欲量表)。根据他们在性欲测量中的得分,参与者被分为相对较低、中等和较高组。刺激材料选自国际情感图片系统,任务包括:(1)对每张图片的效价、唤醒度以及支配感或控制感进行评分;(2)识别之前看过的图像;(3)对之前看过的图片进行第二次评分。性欲水平并未影响男性参与者的反应。性欲较低的女性参与者对性图像的评价不如其他参与者愉快和有唤醒感,并且完成图片识别任务的速度更快。性欲水平显著影响了女性对性图片的兴趣评分。我们还发现性内容会导致延迟。这些延迟在不同性欲组之间没有显著差异。女性中与性欲水平相关的反应差异表明,在临床诊断人群中对这种方法进行更多研究可能有助于理解低性欲,并有助于设计针对因性欲缺乏而产生困扰的干预措施。
