Experimental activation of anti-cuckoldry mechanisms responsive to female sexual infidelity

Recent research indicates that men may have evolved mechanisms dedicated to detecting and responding to the risk of partner infidelity. Because activation of these “anti-cuckoldry” mechanisms depends on partner infidelity, or the perception of partner infidelity, existing evidence for such mechanisms relies on correlational data. The current study tests several predictions regarding men’s anti-cuckoldry mechanisms in an experimental design. As predicted, the results demonstrated: (1a) experimental activation of men’s anti-cuckoldry mechanisms by presenting them with a vignette depicting a female partner’s sexual infidelity; (1b) no activation of men’s anti-cuckoldry mechanisms by presenting them with a vignette depicting a sexual encounter without female infidelity; (2) experimental activation of men’s anti-cuckoldry mechanisms was influenced by their perceived risk of partner infidelity; and (3) women were not influenced by the partner infidelity manipulation.     

Fatherhood today: variations on a theme

Freud explored the concept of the unconscious in some detail in one of his papers on 'metapsychology' in 1915. But this concept is crucial to the birth of psychoanalysis more than twenty years earlier. If we look closely at one of the early cases Freud described in his 1895 book with Breuer, Studies on Hysteria, we can see how that concept was also being born. This paper focuses on the case of Elisabeth von R, to show how the distinctive psychoanalytic understanding of the unconscious was starting to be used there to make sense of her hysterical symptoms. Freud's account and the words he chooses to frame it raise a number of questions about theory and practice in psychoanalysis, which we examine here in relation to unconscious love.     

Donor,Dad, or…? Young Adults with Lesbian Parents’ Experiences with Known Donors

In this exploratory qualitative study of 11 young adults, ages 19–29 years, we examine how young people who were raised by lesbian parents make meaning out of and construct their relationships with known donors. In‐depth interviews were conducted to examine how participants defined their family composition, how they perceived the role of their donors in their lives, and how they negotiated their relationships with their donors. Findings indicate that mothers typically chose known donors who were family friends, that the majority of participants always knew who their donors were, and that their contact with donors ranged from minimal to involved. Further, participants perceived their donors in one of three ways: as strictly donors and not members of their family; as extended family members but not as parents; and as fathers. The more limited role of donors in participants' construction of family relationships sheds light on how children raised in lesbian, gay, and bisexual families are contributing to the redefinition and reconstruction of complex kinship arrangements. Our findings hold implications for clinicians who work with lesbian‐mother families, and suggest that young adulthood is an important developmental phase during which interest in and contact with the donor may shift, warranting a transfer of responsibility from mother to offspring in terms of managing the donor‐child relationship.

Perception of intensity of sperm competition on the part of males

Preferences for certain pornographic themes are hypothesized to have been influenced by our evolutionary history, where sperm competition could play a significant role. The mating system in our australopithecine ancestors, as well as in modern human societies, however, suggests that polygyny (characterized by low risk of sperm competition) has predominated over multi-male multi-female mating systems where high sperm competition is expected. In this study, a sample of men (N = 96) was investigated for their preferences for sexually explicit material showing low (sexual interaction with three women), moderate (one man and one woman) and high intensity of sperm competition (one woman and two men). The participants showed a strong and highly consistent preference for pictures showing moderate and low intensity of sperm competition. These preferences were not influenced by sociosexuality, pornography consumption or attitudes toward pornography. It is suggested that these preferences may mirror psychological adaptations for sperm competition which are activated when the risk of cuckoldry is high. Certain circumstances, where preferences for cues associated with high intensity of sperm competition would be adaptive, are discussed.
