Maia Armstrong awarded BUCNI PhD Honours Training Programme
Maia Armstrong has been selected for the BUCNI PhD Honours Training Programme (2026), a competitive initiative supporting fMRI training and research at UCL and Birkbeck.
The Brain in Action Lab is a research group based in London at Birkbeck, University of London. We study how the brain generates, selects, and evaluates action, and how these processes shape decision-making, memory, and conscious experience across the lifespan.
Our central focus is counterfactual thinking, the brain's ability to construct alternative realities. We investigate how representing what could have been shapes what we do next, how we evaluate our choices, and how we remember the past. This work shows that the mechanisms that support flexible, goal-directed behaviour can also blur the boundary between imagined and performed actions, giving rise to false memories of actions that were never carried out.
Alongside this, we investigate related aspects of human cognition, including voluntary action, the sense of agency, and time perception. Together, these lines of work allow us to understand how actions are generated, experienced, and evaluated, and how these processes unfold across development.
We take an integrative and interdisciplinary approach, combining perspectives from cognitive neuroscience, psychology, and computational modelling. Using behavioural paradigms alongside neuroimaging methods such as EEG and fMRI, we examine how actions are initiated and structured, identify neural markers of voluntary action, and investigate these processes across adult and developmental populations.

Silvia Seghezzi presented 'The Cost of What Might Have Been: False memories for counterfactual actions', and Maia Armstrong presented 'Counterfactual representations and false memories' at the EPS Conference in January 2026.
We show that representing alternative actions can systematically distort memory, giving rise to false recollections of actions that were never executed.
