My research focuses on the study of perception and emotion. In my experiments I use behavioural measures, EEG (electroencephalography, i.e., recording brain electrical activity) and eye-tracking.
One line of my research aims to further our understanding of how the brain processes emotional stimuli. In particular, I investigate how expectations and uncertainty influence emotion processing, and how emotion regulation techniques modify neural activity.
Another line of my research is experimental aesthetics. In a project conducted at TATE Liverpool, we analysed eye movements by viewers in the gallery, and how these are influenced by their personality. I investigate aesthetic evaluations of nature, for example the effects of connectedness to nature and mindfulness on aesthetic experiences. I also conduct research on drawing, in particular the types of errors people commonly make when they draw portraits and objects.
In another line of research I investigate the control of prosthetic limbs, and how prosthetic hand control can be optimised through gaze training.
My teaching covers the following main areas: Cognitive Neuroscience (Year 3 option) and experiment building (using PsychoPy). I supervise undergraduate and postgraduate dissertations, and am very willing to discuss potential projects.@DrNHarrison
