The sexual response includes an emotional component, but it is not clear whether this component is specific to sex and whether it is best explained by dimensional or discrete emotion theories. To determine whether the emotional component of the sexual response is distinct from other emotions, participants (n = 1099) rated 1450 sexual and non-sexual words according to dimensional theories of emotion (using scales of valence, arousal, and dominance) and according to theories of basic emotion (using scales of happiness, anger, sadness, fear, and disgust). In addition, ratings were provided for newly developed scales of sexual valence, arousal, and energy. A factor analysis produced four factors, together accounting for 91.5% of the variance in participant ratings. Using logistic regression analysis, we found that one word category or factor, labeled "sexual," was predicted only by the new sexual arousal and energy scales. The remaining three factors, labeled "disgusting," "happy," and "basic aversive" were best predicted by basic (or discrete) emotion ratings. Dimensional ratings of valence, sexual valence, and arousal were not predictive of any of the four categories. These results suggest that the addition of sexually specific emotions to basic emotion theories is justified and needed to account fully for emotional responses to sexual stimuli. In addition, the findings provide initial validation for the Indiana Sexual and Affective Words Set (ISAWS), supporting its use in future studies.
性反应包括情感成分，但尚不清楚该成分是否特定于性，以及它是否最好通过维度或离散情感理论来解释。为了确定性反应的情感成分是否与其他情感不同，参与者（n=1099）根据情感的维度理论（使用效价、唤醒和支配的量表）和基本情感理论（使用幸福、愤怒、悲伤、恐惧和厌恶的量表）对 1450 个性和非性词汇进行了评分。此外，还对新开发的性效价、唤醒和能量量表进行了评分。因子分析产生了四个因素，共解释了参与者评分方差的 91.5%。使用逻辑回归分析，我们发现一个词类或因素，标记为“性”，仅由新的性唤醒和能量量表预测。其余三个因素，标记为“恶心”、“快乐”和“基本厌恶”，由基本（或离散）情感评分预测最佳。效价、性效价和唤醒的维度评分不能预测四个类别中的任何一个。这些结果表明，将特定于性的情感添加到基本情感理论中是合理的，并且需要充分解释对性刺激的情感反应。此外，这些发现为印第安纳性和情感词汇集（ISAWS）提供了初步验证，支持其在未来研究中的使用。
