    The complex research, policy and industrial challenges of the twenty-first century require collaborative problem solving. Assessments suggest that, globally, many graduates lack necessary competencies.

    Lindström and Tobler find that ostracism of individuals can emerge incidentally, based on initial group structure, and is propagated by a simple reinforcement learning mechanism. The same mechanism can be used to reduce incidental ostracism.

    Analytis et al. study social learning strategies for matters of taste and test their performance on a large-scale dataset. They show why a strategy’s success depends both on people’s level of experience and how their tastes relate to those of others.

    High arousal enables young people to better detect salient stimuli. In older people, arousal leads to increased processing of all stimuli. This difference can be explained by age-related changes in how the locus coeruleus–noradrenaline system interacts with cortical attention networks.
