情色意象是一种非常突出的情感信号，在日常生活中无处不在。然而，性刺激对人类决策的影响却很少被研究。本研究考察了性刺激对风险下财务决策的影响。在每次试验中，在赌博任务之前，在图片分类任务中呈现的要么是色情图像，要么是中性图像。34名男性在做出赌博决定的同时，用皮肤电导反应（SCRs）记录下他们的生理兴奋程度。从行为上看，在两性形象和中性形象的实验中，赌博决定的比例没有差异。从生理学上讲，与中性图像试验相比，参与者在性图像试验中的损失和收益之间的觉醒差异较小（以每美元的微先令计算）。此外，参与者对损失相对于收益的scr预测了中性形象试验中赌博决策的比例，但在性形象试验中却没有。结果与假设一致，即情感上突出的性图像的存在减少了对赌博损失的注意力和唤醒相关反应。我们的研究结果与注意力丧失理论相一致，该理论涉及对损失的认知投资比对收益的认知投资增加。这些发现对于我们理解性图像在日常生活中人类财务决策中的具体作用也有潜在的实际意义，比如在赌场的赌博行为。
Erotic imagery is one highly salient emotional signal that exists everywhere in daily life. The impact of sexual stimuli on human decision-making, however, has rarely been investigated. This study examines the impact of sexual stimuli on financial decision-making under risk. In each trial, either a sexual or neutral image was presented in a picture categorization task before a gambling task. Thirty-four men made gambling decisions while their physiological arousal, measured by skin conductance responses (SCRs), was recorded. Behaviorally, the proportion of gambling decisions did not differ between the sexual and neutral image trials. Physiologically, participants had smaller arousal differences, measured in micro-siemen per dollar, between losses and gains in the sexual rather than in the neutral image trials. Moreover, participants’ SCRs to losses relative to gains predicted the proportion of gambling decisions in the neutral image trials but not in the sexual image trials. The results were consistent with the hypothesis that the presence of emotionally salient sexual images reduces attentional and arousal-related responses to gambling losses. Our results are consistent with the theory of loss attention involving increased cognitive investment in losses compared to gains. The findings also have potential practical implications for our understanding of the specific roles of sexual images in human financial decision making in everyday life, such as gambling behaviors in the casino.
