Victim, perpetrator, and offense characteristics in filicide and filicide-suicide

The purpose of this paper is to provide a critical review of most recent studies of parental and stepparental filicide. A detailed review of the literature revealed the importance of certain demographic, environmental, and psychosocial factors in the commission of child homicide. Our findings indicate that filicides perpetrated by genetic parents and stepparents differ considerably in terms of underlying motivational factors. Data in the literature suggest that biological parents are more likely to choose methods of killing which produce quick and painless death, whereas stepparents frequently kill their wards by beating. Research results demonstrate the victims of maternal filicides to be significantly younger than the victims of paternal filicides. Additionally, filicide–suicide is most often associated with parental psychopathology. Genetic fathers are at the greatest risk of death by suicide after the commission of familicide. These findings are discussed in relation to theoretical frameworks explaining the occurrence of child murder. Further, limitations of reviewed studies and directions for future research are presented

Mate Value Both Positively and Negatively Predicts Intentions to Commit an Infidelity

As a socially monogamous species, humans generally have one committed romantic partner at a time, but sometimes engage in infidelity. Previous research has related infidelity to individual difference traits, including global assessments of “mate value” (relative value as a romantic partner on the “mating market”). We explored the extent to which one\u27s intention to commit an infidelity is uniquely predicted by different components of mate value. The results confirm a negative relationship between one\u27s overall mate value and one\u27s intention to commit an infidelity, and also identify four distinct mate value components (agreeableness/commitment, surgency, emotional stability, and physical attractiveness) that uniquely predict infidelity intention. Two of these factors, surgency (for women) and agreeableness/commitment (for men), positively predict anticipated infidelity. Additionally, the results indicate that men\u27s but not women\u27s infidelity intention is better predicted by the combination of their own and their partner\u27s mate value. Discussion includes interpretations of the results in terms of potential social or personal advancement

Do Women Pretend Orgasm to Retain a Mate?

The current study tested the hypothesis that women pretend orgasm as part of a broader strategy of mate retention. We obtained self-report data from 453 heterosexual women (M age, 21.8 years) in a long-term relationship (M length, 32.8 months) drawn from universities and surrounding communities in the southeastern United States. The results indicated that (1) women who perceived higher risk of partner infidelity were more likely to report pretending orgasm, (2) women who reported greater likelihood of pretending orgasm also reported performing more mate retention behaviors, and (3) women’s perceptions of partner infidelity risk mediated the relationship between pretending orgasm and the performance of cost-inflicting mate retention behaviors, such as Intersexual Negative Inducements (“Flirted with some one infront of my partner”) and Intrasexual Negative Inducements (“Yelled at a woman who looked at my partner”). Thus, pretending orgasm may be part of a broader strategy of mate retention performed by women who perceive higher risk of partner infidelity
