The gene-culture coevolution of group identities: the role of similarity in social-learning

People tend to coordinate their actions with those from the same cultural group. Signals of cultural group membership can be hidden or subtle, however. This is the first study to investigate how the reliability of our similarity-information to others affects whether we use a social-learning strategy to learn from said others. This study investigates social-learning on both an asocial (best-choice) and social (coordination game) task.

Sex on the mind? Using the conjunction fallacy to test for the sexual overperception bias

The sexual overperception bias is the hypothesised tendency for men to over-infer the sexual interest of women. We test whether this cognitive bias exists using a conjunction fallacy task. Men may make a conjunction fallacy by rating the conjunction of women wanting to chat and being sexually interested as more likely than a woman just wanting to chat. This error would offer support for the overperception bias. This study will also design conjunction fallacy tasks to assess a different bias in women, commitment scepticism. It is predicted that women will make conjunction fallacies by rating it more likely that men want to have sex but not a committed relationship than choosing sex only
