In a common-pool resource experiment, Koomen and Herrmann show that six-year-old children are collectively able to avoid collapsing a shared resource and use similar strategies to adults.
A model of minority–majority group interactions shows that minority cultural practices can be preserved from cultural homogenization where a group boundary allows free movement of minority members, but excludes members of the more powerful majority.
Using an imagery-perception paradigm, the authors find that imagined speech affects the perceived loudness of sound. They also show that early neural responses correlate with the loudness ratings, even without external stimulation.
Glaze et al. show that individual variability in learning from noisy evidence involves a bias–variance trade-off that is best explained by a model using a sampling algorithm that approximates optimal inference.
Waniek and colleagues show that individuals and communities can disguise themselves from detection online by standard social network analysis tools through simple changes to their social network connections.
Strimling and colleagues develop and empirically test a mathematical model of the 'civilizing process', that is, the tendency of social norms about violence and hygiene to become increasingly strict over time.
Steinbeis and colleagues show that chimpanzees and six-year-old children will pay a cost to see the punishment of an antisocial agent when it is deserved, suggesting that both are motivated to see just punishment enacted.
Intracranial recordings from epileptic patients during a number of different behavioural tasks reveal, in impressive spatiotemporal detail, that the human brain links perception and action through persistent neural activity in the prefrontal cortex and functionally linked brain regions.
The authors used graph signal processing to examine whether fMRI signals correspond to underlying anatomical networks. They found that alignment between functional signals and anatomical structure was associated with greater cognitive flexibility.
In a series of 11 experiments, the authors show that what has traditionally been considered 'pitch perception' is mediated by several different mechanisms.
Using magnetic resonance imaging and electroencephalography during a face-discrimination task, the authors show face-processing lateralization in infants in the first postnatal semester, despite a corpus callosum mature enough to transfer visual information across hemispheres.
Over four functional MRI experiments, Axelrod et al. show that several cognitive processes function simultaneously during self-generated mental activity.
Just et al. develop a highly accurate biological classification method for identifying suicidal ideators by applying machine learning to neural representations of death- and life-related concepts.
Direct-to-consumer advertising of pharmaceutical drugs requires mention of severe side effects, along with the most frequent. Sivanathan and Kakkar show that this practice dilutes consumers’ judgements of the overall severity of side effects
Women often behave more prosocially than men. Soutschek et al. use pharmacology and neuroimaging to show that the neural reward system appears to be more sensitive to prosocial rewards in women than men, providing a neurobiological account for this gender difference.
Haruno et al. combine functional magnetic resonance imaging, an economic game and depression self-reports to show that brain activity in the amygdala and hippocampus induced by inequity can predict present and future depression indices.
Pedroni et al. show that risk preferences vary across behavioural elicitation methods, challenging the view that risk preferences can be consistently captured by a single method.
Using behavioural experiments and computational modelling, Navajas and colleagues provide a systematic characterization of individual differences in human confidence.
