There is increasing evidence that the use of elec-tronic communication technology (ECT) is being integrated into romantic relationships, which can be used as a medium to control a romantic partner. Most research focuses on the vic-tims of cyber dating abuse, however, we focused on the factors that predict perpetration of cyber dating abuse. We explored whether aggression (verbal aggression, physical aggression, anger and hostility), romantic jealousy (emotional, cognitive and behavioral jealousy), and gender predicted perpetration of cyber dating abuse (n = 189). We found that hostility, behav-ioral jealousy and gender significantly predicted perpetration of cyber dating abuse. The findings of this study contribute to our understanding of the psychological factors that drive cyber dating abuse in romantic relationships.
Research suggests that individual differences in attachment style predict the perpetration of digital dating abuse. In addition to attachment style, no research, to our knowledge, has explored the role of mate value in the perpetration of digital dating abuse. In this paper, we argue that digital dating abuse is a contemporary cost-inflicting mate retention behaviour, where larger mate value discrepancies between partners are associated with higher levels of digital dating abuse (n = 167). As expected, high mate value discrepancy and attachment anxiety were associated with high levels of digital dating abuse. We provide novel support for the relationship between mate value discrepancy and digital dating abuse. Our findings provide support for additional, unexplored factors which lead to the perpetration of digital dating abuse.
Several studies find that male individuals are more altruistic toward attractive women, suggesting altruism may serve as a courtship display. Many studies exploring this phenomenon have used vignettes and facial images. We tested the sexual selection hypothesis as an explanation for altruistic behavior, where players played the dictator game with “live” participants. Two studies were conducted (Study 1, n = 212; Study 2, n = 188) where we manipulated stakes and anonymity between participants to explore the relationship between the dictator’s allocations and their perceived attractiveness of the recipient. We found no relationship between attractiveness and altruism. Dictators were consistently fair when allocating stakes, irrespective of the recipients’ attractiveness
Explaining cooperative tendencies through an evolutionary lens has been problematic for theorists. Traditional explanations derive from theories of reciprocity, biological markets, and more recently via partner choice and sexual selection. The sexual selection hypothesis has been tested within game-theoretic frameworks gaining empirical sup- port in explaining the evolution of altruism. Males have been found to be more altruistic towards attractive females. However, previous research has predominantly adopted a design where participants are not engaging with ‘real people’. Instead, participants make decisions when viewing images or hypothetical scenarios without visual cues. The present study aimed to investigate the sexual selection hypothesis using a face-to-face game theoretic framework. One hundred and thirty-eight participants played a 2-round ultimatum game with chocolate coins as the monetary incentive. We find, that physical attractiveness had no influence on generosity and cooperation when participants play a face-to-face ultimatum game. Instead, proposers were fair when allocating stakes, offering an average of half the endowment to responders. This study refutes the link between the sexual selection hypothesis and generosity when playing economic games with real people. Fairness appeared to drive generosity and cooperation
The role of prosocial behaviour in female mate choice has been extensively explored, focusing on the desirability of altruism in potential mates, as well as altruism being a mating signal.However, little research has focused on the desirability of heroism and altruism in potential partners. Furthermore, the synergistic effect of attractiveness on the desirability of prosocial behavior has only recently been explored, and to our knowledge, has not explored in relation to the desirability of heroism in a romantic partner. We explored the effect of prosociality and attractiveness on female desirability ratings (n=198), and whether desirability was influenced by whether women were seeking a short-term or long-term relationship. We find that women are attracted to men who display heroism and altruism, and this preference is higher when the male is attractive compared to unattractive. Furthermore, preferences for prosocial traits were higher when seeking a long-term compared to a short-term partner. Our findings add to the literature on prosocial behaviour and mate choice.

Explaining altruism through an evolutionary lens has been a challenge for evolutionary theorists. Where altruism towards kin is well understood through kin selection, altruism towards non-kin is an evolutionary puzzle. Contemporary research has found that, through a game-theoretic framework, sexual selection could be an explanation for the evolution of altruism. Research suggests that males are more altruistic towards females they are interested in engaging with, sexually or romantically when distributing stakes in economic games. This study, adopting a between-groups design, tested the sexual selection explanation for altruism by asking participants to self-report altruistic and cooperative intention when reading moral scenarios accompanied by attractive or unattractive images. We find that participants, particularly males, report being more altruistic and cooperative when viewing an attractive image of a female. This study replicates the sexual selection hypothesis in explaining altruism through an alternative experimental framework to game theory.
