Gender differences in animal cognition science

Women's representation in science is increasing steadily, with some fields closing gender parity in terms of participation and scientific output. Animal cognition appears to fall into that category. Our current analysis of gender author balance (women versus men) in 600 animal cognition papers supported parity in many aspects, but also revealed some remaining disparities. Women animal cognition scientists often held first authorship positions (58% of the studies), received similar numbers of citations, and published in equally high impact factor journals as men. Women were still under represented in last-author position, which often reflects seniority status (37% of last authors were women). There were interesting results when we considered the gender of teams (of two or more authors): all-women author teams were the minority in our dataset and received on average fewer citations than all men or mixed author teams, regardless of the quality of the journal (as measured by the journal's impact factor). Women more often focussed on mammals, whereas men more often focussed on fish, both as first authors and as same-gender teams. Men, as first author or in men-only teams, restricted their research more often to organisms of a single sex, compared to women, as first author and as members of a team. Our study suggests that there are many indices of the significant contribution of both women and men scientists in animal cognition, although some gender biases may remain.
