A commonplace observation in humans is that close genetic relatives tend to avoid one another as sexual partners. Despite the growing psychological research on how antierotic attitudes develop toward relatives, few studies have focused on actual behavior. One prediction, stemming from parental investment theory, is that women should be more vigilant of reproduction-compromising behaviors, such as inbreeding, during times of peak fertility than during times of low fertility. Indeed, females of… Expand

No evidence that inbreeding avoidance is up-regulated during the ovulatory phase of the menstrual cycle
TLDR
A longitudinal design was used to investigate the relationship between changes in women’s steroid hormone levels and their perceptions of faces experimentally manipulated to possess kinship cues and found no evidence that women reported spending less time in the company of male kin or thought about male kin less often during the fertile phase of the menstrual cycle. Expand
No evidence that inbreeding avoidance is up-regulated during the ovulatory phase of the menstrual cycle - Study 1
TLDR
A longitudinal design was used to investigate the relationship between changes in women’s steroid hormone levels and their perceptions of faces experimentally manipulated to possess kinship cues and found no evidence that women reported spending less time in the company of male kin or thought about male kin less often during the fertile phase of the menstrual cycle.

Cycling on the fast track: Ovulatory shifts in sexual motivation as a proximate mechanism for regulating life history strategies
Abstract In an ancestral world without modern contraception, how did women regulate their fertility? We argue that fertility may be regulated by context-dependent changes in sexual motivation thatExpand
Human Sexuality and Inbreeding Avoidance
In this chapter, we discuss the logic driving the evolution of inbreeding avoidance systems. In addition, we review literature regarding the negative effects of inbreeding, discuss how disparateExpand
Hormonal regulation of women′s prosocial, but not sexual, responses to kinship cues
TLDR
The proposal that women′s hormonal status influences attitudes to kin because of benefits associated with increased kin affiliation during pregnancy supports the inbreeding-avoidance hypothesis. Expand
The ovulatory shift: proceptive and receptive mating behaviours across the menstrual cycle
TLDR
This dissertation provides rationale and preliminary support for the reliability and validity of the PARMSS and provides further evidence that women’s sociosexuality is associated with differential shifts in proceptive mating behaviour across the menstrual cycle. Expand
The Self-Regulation Effect of Fertility Status on Inbreeding Aversion: When Fertile, Disgust Increases more in Response to Descriptions of One's Own than of Others' Inbreeding
TLDR
The ovulatory shift was stronger in descriptions where women themselves were described as engaging in inbreeding, and the latter effect was explained as due to self-reflection. Expand
Intergenerational incest aversion: self-reported sexual arousal and disgust to hypothetical sexual contact with family members
Abstract The biological costs of inbreeding are expected to have shaped human incest aversion. These costs depend on biological sex, relatedness, and age. Whereas previous studies have focused onExpand
Strangers With Benefits
TLDR
Working from an evolutionary framework, a unique pattern of outgroup attraction is identified, such that attraction to outgroup men increases as fertility increases across the cycle in naturally cycling women. Expand
Human ovulation cues
In most mammals, cues of impending ovulation — including changes in appearance and sexual behavior — mark the fertile phase within the ovulatory cycle. Such cues were long thought to have beenExpand

Can Men Detect Ovulation?
In contrast to our closest cousin, the chimpanzee, humans appear at first to lack cues of impending ovulation that would mark the fertile period in which a female can become pregnant. Consequently,Expand
Women's Sexual Strategies: The Evolution of Long-Term Bonds and Extrapair Sex
TLDR
It is argued that the evidence poses a challenge to some existing theories of human mating and adds to the understanding of the subtlety of women's sexual strategies. Expand
Female transfer and inbreeding avoidance in social mammals
TLDR
It is shown that in polygynous mammals where females commonly remain to breed in their natal group, the average age at first conception typically exceeds the average period of residence of adult males in breeding groups. Expand
Human oestrus
TLDR
It is proposed that the term oestrus appropriately applies to this phase of female sexuality occurring near ovulation, and ways that fertile-phase sexuality in women has been shaped to partly function in the context of extra-pair mating are suggested. Expand
The Proximate Mechanisms of Natal Dispersal in Female Horses
TLDR
The results of this study do not support the hypothesis that a function of natal dispersal is to reduce intrasexual competition, and as predicted by the inbreeding avoidance hypothesis, the primary cause of dispersal appeared to be sexual attraction to unfamiliar males. Expand
Conditional expression of women's desires and men's mate guarding across the ovulatory cycle
TLDR
These findings demonstrate ovulation-contingent shifts in desires and behaviors that are sensitive to varying fitness payoffs, and they provide support for the good genes hypothesis of human female extra-pair mating. Expand
Women's Preferences for Male Behavioral Displays Change Across the Menstrual Cycle
TLDR
Women's preference for men who displayed social presence and direct intrasexual competitiveness increased on high-fertility days relative to low-f fertility days, but only in a short-term, not a long-term mating context, adding to the growing literature indicating that women's mate preferences systematically vary across the reproductive cycle.

FEMALE CONTROL OF PATERNITY DURING COPULATION: INBREEDING AVOIDANCE IN FERAL CATS
TLDR
The hypothesis that female cats control paternity of their offspring during copulation is supported, and female receptivity to male attempts among the eight females is compared and how female traits affect their receptivity is tested. Expand
Familiarity and Inbreeding Avoidance in the Gray-Tailed Vole (Microtus canicaudus)
TLDR
In the held, familiarity of voles may increase in low density populations and reproductive behavior may decline as a result, and familiarity, kin recognition, and inbreeding avoidance may play important roles in vole population cycles. Expand
Menstrual cycle variation in women's preferences for the scent of symmetrical men

  • Psychology, Medicine
  • Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 1998
TLDR
Normally cycling women near the peak fertility of their cycle tended to prefer the scent of shirts worn by symmetrical men, while normally ovulating women at low fertility within their cycle, and women using a contraceptive pill showed no significant preference for either symmetrical or asymmetrical men's scent.
