Academic and research interests

Image perception and visual search

In the North West for the last 20 years there has been a network of academics (Psychology, Computer Science & Medical Imaging), from the University of Cumbria, Lancaster University and Edge Hill University, researching Medical Image Perception. Most of the research uses eye tracking to gain an insight into medical image interpretation, the type of errors made, and the development of expertise. The rationale being that for some radiological tasks such as lung nodule detection and breast screening, error rates are typically 30% and have not changed for the last 60 years.  The underpinning ethos of the group is to apply the rigour of experimental psychology methods to help understand medical image perception and decision making. This has led to the use and adaptation of experimental psychology paradigms to enhance our understanding of observer performance.  Participant populations have been psychology students as naive observers, radiography students, clinical radiographers reporting on medical images and consultant radiologists. We are now starting to understand how clinicians adapt the perceptual skills we all have to the radiological task, and this is enabling us to refine current models of medical image perception.

Cochrane Systematic Reviews

Systematic review and meta-analysis plays a vital role in critically appraising evidence to inform evidence-based healthcare. I have a role as author and co-author contributing to reviews as part of Cochrane Airways. Systematic review techniques inform my delivery of BSc and MSc research modules.

Fetal eye movements

The use of 4D/2D ultrasound to measure fetal eye movements in response to visual stimuli.

Research supervision

Current Research Students

Frances Sapsford - The effects of stroke in hand laterality judgement

Margot McBride - Cushing's syndrome and Cushing's disease, patient perspective.
