Abstract

We examined the stability of same-sex and other-sex attractions among 294 heterosexual, lesbian, gay, and bisexual men and women between the ages of 18 and 40 years. Participants used online daily diaries to report the intensity of each day's strongest same-sex and other-sex attraction, and they also reported on changes they recalled experiencing in their attractions since adolescence. We used multilevel dynamical systems models to examine individual differences in the stability of daily attractions (stability, in these models, denotes the tendency for attractions to "self-correct" toward a person-specific setpoint over time). Women's attractions showed less day-to-day stability than men's, consistent with the notion of female sexual fluidity (i.e., heightened erotic sensitivity to situational and contextual influences). Yet, women did not recollect larger post-adolescent changes in sexual attractions than did men, and larger recollected post-adolescent changes did not predict lower day-to-day stability in the sample as a whole. Bisexually attracted individuals recollected larger post-adolescent changes in their attractions, and they showed lower day-to-day stability in attractions to their "less-preferred" gender, compared to individuals with exclusive same-sex or exclusive other-sex attractions. Our results suggest that both gender and bisexuality have independent influences on sexual fluidity, but these influences vary across short versus long timescales, and they also differ for attractions to one's "more-preferred" versus "less-preferred" gender.

摘要

我们研究了294名年龄在18至40岁之间的异性恋、女同性恋、男同性恋和双性恋男性与女性中同性和异性吸引力的稳定性。参与者使用在线日常日记来报告每天最强的同性和异性吸引力的强度,他们还报告了自青春期以来回忆起的自身吸引力的变化。我们使用多层次动态系统模型来研究日常吸引力稳定性的个体差异(在这些模型中,稳定性表示吸引力随着时间推移朝着个人特定的设定点“自我校正”的趋势)。女性的吸引力比男性表现出更小的日常稳定性,这与女性性流动性的概念一致(即对情境和背景影响的性敏感增强)。然而,女性回忆起的青春期后性吸引力变化并不比男性大,而且在整个样本中,回忆起的青春期后较大变化并不能预测较低的日常稳定性。与具有排他性同性或排他性异性吸引力的个体相比,双性恋吸引的个体回忆起青春期后其吸引力有更大变化,并且他们对“较不喜欢”性别的吸引力表现出更低的日常稳定性。我们的结果表明,性别和双性恋对性流动性都有独立影响,但这些影响在短期和长期时间尺度上有所不同,而且对一个人“更喜欢”和“较不喜欢”性别的吸引力也有所不同。
