Publication Evidence of the active participation of women in the intergroup conflict based on the use of aggression and cooperation(2023) Muñoz Reyes, José Antonio; Torrico-Bazoberry, Daniel; Polo Rodrigo, Pablo; Figueroa, Oriana; Guzmán-Lavín, Eugenio; Fajardo, Gabriela; Valenzuela-Martinez, Nohelia T.; Belinchón, Montserrat; Rodriguez-Sickert, Carlos; Pita, MiguelIntergroup conflict has been a persistent aspect of human societies since the emergence of our species. Various researchers have proposed that competition between groups has acted as a key selective force throughout human evolutionary history. Such intergroup competition for limited resources exacerbated the expression of intergroup aggression and intragroup cooperation. Furthermore, it would have a sexual dimorphism, with men demonstrating increased sensitivity to conflict threats—in order to maximize reproductive opportunities—, while women generally reject from active engagement in intergroup conflict. In the present study, we conducted behavioral experiments under controlled laboratory conditions to measure cooperation and aggression from using virtual games, specifically the Public Good Games and the Point Subtraction Aggression Paradigm, in a sample of 541 participants. We created control and experimental intergroup competition scenarios, where aggression and cooperation were necessary to increase monetary rewards. Our results shows that men modulate aggression and cooperation in the presence of intergroup conflict. In addition, our data also reveals that women cooperate more than men and display heightened levels of cooperation and aggression when confronted with intergroup conflict. These findings prompt a reevaluation of current functional theoretical models concerning the role of women in intergroup conflict and suggest that the dynamics of human aggression and cooperation may be more nuanced than previously believed.Publication Linking physical violence to women’s mobility in Chile(2023) Contreras, Hugo; Candia Vallejos, Cristian; Troncoso, Rodrigo; Ferres, Leo; Bravo, Loreto; Rodriguez-Sickert, CarlosDespite increased global attention on violence against women, understanding the factors that lead to women becoming victims remains a critical challenge. Notably, the impact of domestic violence on women’s mobility—a critical determinant of their social and economic independence—has remained largely unexplored. This study bridges this gap, employing police records to quantify physical and psychological domestic violence, while leveraging mobile phone data to proxy women’s mobility. Our analyses reveal a negative correlation between physical violence and female mobility, an association that withstands robustness checks, including controls for economic independence variables like education, employment, and occupational segregation, bootstrapping of the data set, and applying a generalized propensity score matching identification strategy. The study emphasizes the potential causal role of physical violence on decreased female mobility, asserting the value of interdisciplinary research in exploring such multifaceted social phenomena to open avenues for preventive measures. The implications of this research extend into the realm of public policy and intervention development, offering new strategies to combat and ultimately eradicate domestic violence against women, thereby contributing to wider efforts toward gender equity.Publication The lexical divide: propositive modes and non agentic attitudes define the progressive left in Chile(2024) raveau, maria; Couyoumdjian, Juan Pablo; Fuentes-Bravo, Claudio; Rodriguez-Sickert, Carlos; Candia Vallejos, CristianInternal factors-such as psychological traits or individual attitudes-relate to and explain political cleavages. Yet, little is known about how locus of control, agency, and modal atti tudes impact political ideology. Utilizing textual analysis within the context of the Chilean 2015 constituent process, we go beyond traditional survey methods to explore community clusters in “Values” and “Rights” networks built upon the deliberation of 106,000 people. Our findings reveal distinct attitudinal patterns across political orientations: the progressive left generally exhibits a more propositive and non-agentic attitude, the traditional left adopts an evaluative stance towards values, and the right-wing community leans towards a factual attitude but shifts to an evaluative stance when discussing rights. These results underscore the role of psychological constructs in shaping political ideologies and introduce textual analysis as a robust tool for psychological and political inquiry. The study offers a compre hensive understanding of the complexities of political behavior and provides a new lens through which to examine the psychology of political ideology.Publication The effect of intergroup competition outcome on ingroup cooperation: insights from the male warrior hypothesis(2024) Belinchón, Montserrat; Polo Rodrigo, Pablo; Rodriguez-Sickert, Carlos; Figueroa, Oriana; Valenzuela-Martinez, Nohelia T.; Pavez, Paula; Muñoz Reyes, José AntonioIntroduction: The Male Warrior Hypothesis (MWH) proposes that sex-specific elective pressures have promoted male cooperation with the ingroup members to outcompete rival groups. However, intergroup conflicts do not occur in isolation and the outcomes of previous competitions may influence group cooperativeness. Since this phenomenon is not well understood, we aimed to shed light on the effect of previous competition outcome on later cooperative behavior under intergroup conflicts. Based on the MWH, we hypothesized that repeated contests between groups could enhance ingroup cooperation, regardless of the outcome of the previous contest because status is at risk, but when competition is not present, participants would move to the symmetric equilibria. Methods: To test this hypothesis, we recruited 246 individuals organized in groups of 6 and measured cooperation using a threshold public good game over two rounds, manipulating the outcome in the first round to create groups of winners and losers. Results: Our results show that intergroup conflict scenarios promoted cooperation in both victory and defeat conditions, whereas, in the control scenario only losers increased their cooperation. Discussion: We argue that winners under the presence of an external threat may enhance in-group cooperation in order to assure their status; whereas, losers may be attempting to regain it.
