Project Description

The Social Decision Neuroscience lab (www.sdn-lab.org) led by Dr. Patricia Lockwood and Motivation and Social Neuroscience lab (www.msn-lab.org) led by Dr. Matthew Apps, are offering a competitively funded project examining the fundamental behavioural, computational and neural mechanisms of social decision-making in humans.

Background

Humans are highly social creatures, spending much of their lives thinking about and making decisions that affect other people. Two crucial processes that underpin our social behaviour are how we learn about which of our actions help and avoid harming others and how motivated we are to engage with others. However, currently, there is a limited understanding of the behavioural, computational and neural mechanisms that underpin social decision-making.

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 behaviour between people, and the fundamental mechanisms (Apps et al., 2016; Wittmann, Lockwood & Rushworth, 2018). Moreover, such models can bridge levels of explanation from neuroscience to psychology. Models of reinforcement learning can be applied to understand social learning and models of effort-based decision-making, that quantify how we weigh up the costs of putting in effort against the benefit of gaining rewards, will be applied to understand social motivation.

Projects are being solicited from highly motivated students interested in using these novel approaches to examine the behavioural and neural basis of social learning and social motivation. Asking questions about how altruistic people are, what the mechanisms in the brain are that guide altruistic and selfish behaviours, and in what contexts are people more or less prosocial. Such approaches can be used to understand a range of social behaviours, from charitable behaviour, atypical social motivation (apathy) and disordered social cognition.

Students will receive advanced training in methods from psychology, cognitive neuroscience, neuroimaging, and computational modelling. The findings will have important implications for everyday decision-making with potential applications to disorders of social behaviour.

Research techniques and training

• Advanced techniques in computational modelling (model fitting, model simulation, model generation)
• Analysis of brain imaging data (functional MRI, structural MRI, connectivity analyses)
• Programming of behavioural tasks (Matlab, Presentation)
• Advanced statistical analysis (Matlab, R)
