“…Most research conducted in this area has involved public displays of altruism involving financial resources (Iredale, van Vugt & Dunbar, 2008;van Vugt & Iredale, 2013), and/or altruistic behaviors in experimental economic games such as the ultimatum, dictator, and prisoner's dilemma games using financial sources (Bhogal, Galbraith & Manktelow, 2016b, 2017Farrelly et al, 2007;Saad & Gill, 2001). However, several authors argue that researchers should explore altruistic behavior using a variety of measurements and experimental frameworks, suggesting much of the literature exploring the evolution of altruism using economic games (particularly those which only utilize financial endowments) in conditions of low ecological validity can only explain financial altruism, not alternate forms of altruism which we see in everyday life (Farrelly & Bennett, 2018;Farrelly, Moan & White, 2015). As a result, this conceptual replication study explores whether men and women use altruistic behavior with potential romantic partners that is based on costs relevant to their lives that relate to time rather than finances available.…”
