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 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.
