PhD project title: Behavioural and brain mechanisms of social learning and motivation
University of Registration:University of Birmingham
Humans are highly social creatures, spending much of their lives thinking about and making decisions that affect other people. However, whilst the capacity to successfully engage in social interactions is critical, we still lack a clear characterisation of the mechanisms of social decision-making and its brain and behavioural basis (Lockwood et al., 2020).
Recent advances in cognitive neuroscience have allowed the combination of measures of behaviour, computational models of decision-making, neuroimaging and self-report which can get us closer to understanding why there are differences in social decision-making between people, and the fundamental mechanisms (Ruff & Fehr, 2014; Wittmann, Lockwood & Rushworth, 2018; Lockwood & Klein-Flugge, 2021). Moreover, such models can bridge levels of explanation from neuroscience to psychology.
Objectives and methods
The proposed project will use these novel approaches to examine the behavioural and neural basis of social learning – how we learn which of our actions help and avoid harming others – and social motivation – how willing we are to put in effort to help. First we will collect big-data samples online from novel computerised tasks measuring social learning and motivation, combined with computational modelling. Next there will be an opportunity to use functional magnetic resonance imaging (fMRI) and Magnetoencephalography (MEG). fMRI has excellent spatial resolution and MEG has excellent temporal resolution. We will use these approaches with data analysis techniques that can combine them together.
Training and outcomes
Students will receive advanced training in methods from psychology, cognitive neuroscience, neuroimaging, and computational modelling. The findings will have important implications for healthy development across the lifespan and potential interventions to reduce antisocial behaviour.
