  • How far would you go for love and sex? (Western Sydney University) - The dating world has changed for better or worse with the advent of GPS-based dating applications like Tinder, Match, Bumble, and more. For the first time, people have the ability to search for partners out of their normal social networks and daily travels. This has introduced a relatively new factor to consider when trying to choose a date: the distance a person is from you. We are conceptualizing this distance as an individual difference that may be influenced by personality and situational factors and there may be sex differences as well. In this study, we ask you to help us in this groundbreaking research to better understand the trials and tribulations of modern daters. This 5-minute study is completely voluntary and partaking in it will set you up to win a $50 USD gift card for Amazon. [Added August 2, 2016]
