  • Chen et al. construct a model of the neural bases of semantic representation that unifies domain-specific (distinct systems represent different kinds of things) and domain-general (knowledge for all kinds is encoded in a single network) accounts.

  • Pah et al. analyse gun violence incidents at US schools for the period 1990–2013 and find heightened rates in the period 2007–2013. Indicators of economic distress significantly correlate with increases in the rate of gun violence.

  • By analysing the supermarket purchases of more than 280,000 people over several years, Riefer et al. show that people’s preferences follow their choices, rather than the other way around.

  • Using whole-genome data for single-nucleotide polymorphism and results from genome-wide association studies, the authors show that people’s preference for pairing with those with similar phenotypic traits has genetic causes and consequences.

  • Gomez-Lievano and colleagues develop a new theory of scaling in cities — how the prevalence of phenomena such as education and crime changes with population size — by unifying models of economic complexity and cultural evolution.

  • He and colleagues show that attention plays a key role in anchoring visual orientation in 3D space. The effect of attention was contingent on the ground being visible, suggesting our terrestrial visual system is best served by its ecological niche.

  • The authors asked human participants to listen to and imitate randomly generated drumming sequences from each other. Participants turned initially random sequences into rhythmically structured patterns that are characterized by all six statistical universals found in world music.

  • Every time we make a choice, we maintain an explicit representation of our confidence in that choice. Using eye-tracking and behavioural measures, the authors show that tracking decision uncertainty is helpful in guiding future behaviour.

  • Faces are positioned in a statistical distribution of faces extracted from the environment. Social inferences from faces (for example, trustworthiness) arise from the statistical position of faces in this learned distribution.
