Philippa Johnson is postdoctoral researcher within the CoCoSys Lab in the unit of Cognitive Psychology, under the supervision of Prof. Anne Urai and Prof. Sander Nieuwenhuis. She is currently investigating the effects of fluctuations in internal state on decision making behaviour and neural coding.

Research on decision making
Johnson's PhD research investigated processing of moving objects, using EEG to probe neural representations during the first 200ms after presentation of a stimulus. In her postdoc, she is considering behavioural fluctuations at a much longer timescale, by looking at how different engagement states impact behavioural performance and neural processing.
Short CV
Johnson completed a Bachelor's degree in Psychology at the University of Bath in the UK, followed by a Master's in Clinical and Cognitive Neuropsychology at the Vrije Universiteit, Amsterdam.
Her PhD was supervised by Prof. Hinze Hogendoorn and Prof. Stefan Bode, and was based at the University of Melbourne and the University of Amsterdam. During her PhD, she investigated how the brain compensates for the time required for neural transmission and processing during motion perception, using a combination of electroencephalography (EEG) and behavioural experiments.
