The influence of reward and punishment on motor learning and retention

Motor learning (the ability of the brain to learn and update how an action is executed) is a fundamental process which influences many aspects of our lives such as learning to walk during childhood; the day-to-day behavioural adjustments required as an adult or in healthy ageing; and the rehabilitation process following an illness or injury. Despite the impact to society, it has proved extremely difficult to develop interventions that significantly enhance human motor learning. Therefore, devising protocols which optimise motor learning is a state-of-the-art research question that promises to deliver scientific, clinical and societal impact.

Seeking reward and avoiding punishment are powerful factors in motivating humans to alter behaviour during cognition-based learning (selecting which action to perform), with sensitivity to reward and punishment being biased by the availability of dopamine in the brain. Intriguingly, reward and punishment are also known to affect generic motor learning (deciding how an action is executed) tasks which involve multiple underlying mechanisms. However to establish their potential for optimizing motor learning, we must understand how explicit reward- and punishment-based motivational feedback impact motor learning systems with unique computational and anatomical features.

Using a combination of behavioural analysis, computational modelling, genetics and brain imaging, this PhD project will contribute to the first systems-based account of how reward, punishment and dopamine influence motor learning. Specifically, the successful candidate will investigate how motor memories are consolidated across multiple days and the influence reward has on this process.
It will further examine whether memory retention can be enhanced through reward-based implicit cues and if this process can be captured with EEG.
