Experts in action: why we need an embodied social brain hypothesis (2021)
Journal Article
Barrett, L., Henzi, S. P., & Barton, R. A. (2022). Experts in action: why we need an embodied social brain hypothesis. Philosophical Transactions of the Royal Society B: Biological Sciences, 377(1844), https://doi.org/10.1098/rstb.2020.0533

The anthropoid primates are known for their intense sociality and large brain size. The idea that these might be causally related has given rise to a large body of work testing the ‘social brain hypothesis'. Here, the emphasis has been placed on the...

Social learning strategies and cooperative behaviour: Evidence of payoff bias, but not prestige or conformity, in a social dilemma game (2021)
Journal Article
Watson, R., Morgan, T. J., Kendal, R. L., Van de Vyver, J., & Kendal, J. (2021). Social learning strategies and cooperative behaviour: Evidence of payoff bias, but not prestige or conformity, in a social dilemma game. Games, 12(4), Article 89. https://doi.org/10.3390/g12040089

Human cooperation, occurring without reciprocation and between unrelated individuals in large populations, represents an evolutionary puzzle. One potential explanation is that cooperative behaviour may be transmitted between individuals via social le...

The role of population size in folk tune complexity (preprint) (2021)
Journal Article
Street, S., Eerola, T., & Kendal, J. The role of population size in folk tune complexity (preprint). https://doi.org/10.31234/osf.io/2he8k. Manuscript submitted for publication

A positive correlation between population size and cultural complexity is perhaps one of the most consistent findings in the field of cultural evolution. However, previous findings are largely based on studies of technology and are not necessarily ge... Read More about The role of population size in folk tune complexity (preprint).

Definition and interpretation effects: How different vigilance definitions can produce varied results (2021)
Journal Article

Animals use vigilance to detect or monitor threats. While numerous aspects of vigilance have been studied across a wide range of species, little work has explored the methodological variation that has emerged across these studies. Different approache... Read More about Definition and interpretation effects: How different vigilance definitions can produce varied results.

Testing Mate Choice Hypotheses in a Transitional Small Scale Population (2021)
Journal Article
Boothroyd, L., Jucker, J., Thornborrow, T., Tovee, M., Batres, C., & Penton-Voak, I. (2021). Testing Mate Choice Hypotheses in a Transitional Small Scale Population. Adaptive Human Behavior and Physiology, 7(3), 220-244. https://doi.org/10.1007/s40750-021-00173-5

Objective Tests of theories of mate choice often rely on data gathered in White, industrialised samples and this is especially the case for studies of facial attraction. Our understanding of preferences for sexual dimorphism is currently in flux and... Read More about Testing Mate Choice Hypotheses in a Transitional Small Scale Population.

Conformity to Bergmann's rule in birds depends on nest design and migration (2021)
Journal Article

Ecogeographical rules attempt to explain large-scale spatial patterns in biological traits. One of the most enduring examples is Bergmann's rule, which states that species should be larger in colder climates due to the thermoregulatory advantages of...
