Profile

I joined the University of Surrey as a mature student and read for a BSc in Applied Psychology. In my 3rd year I was introduced to visual psychophysics by Mark Bradshaw who supervised my undergraduate project. Following my degree I worked for a year as a Research Assistant and then completed a PhD in Mark’s laboratory where my thesis investigated spatial coordinate frameworks of selective attention. I then moved to a postdoctoral research position at Southampton University’s Visual Cognition Unit where I worked with Kyle Cave Nick Donnelly and Tammy Menneer on a project investigating visual search in real-world situations. In 2003 I was awarded an MRC Career Development Fellowship at the MRC’s Institute of Hearing Research where I learned about auditory science and Magnetic Resonance Imaging (fMRI) under the supervision of Deb Hall. My first lectureship was at Nottingham Trent University and I moved to the University of Leicester in 2009. I have maintained my interests in visual and auditory cognition and my research focusses on interactions between selective attention and short-term memory across the life-span in neurologically normal and clinical populations.

Research

Our ability to process and act on information in the environment is limited. This reflects constraints imposed by perceptual mechanisms as well as post-perceptual processes such as short-term memory. To deal with these constraints, individuals must select, encode, retain and act upon sensory information in response to changing task demands. Psychologists and neuroscientists use the term “attention” to describe the cognitive and neural processes involved in the selection or “prioritisation” of sensory information in the pursuit of goals and intentions. My research interests focus on the cognitive processes that prioritise sensory information during visual sampling, encoding and maintenance in short-term memory.

Supervision

I am interested in projects investigating aspects of perception visual attention and short-term memory.

Current PhD students are working on:

1) Interactions between perception and cognition in age-related changes in visual search

2) The impact of training on physiological and psychological responses to stress among police firearms officers

Other areas of research include:

1) Investigating the use of pupillometry as an index of mental load in normal and clinical populations (i.e. tinnitus dementia & ME)

2) The impact of prior knowledge and experience on eye movements during everyday visual tasks

3) Cognitive strategies to optimise visual and auditory discrimination in response to age-related changes in visual and auditory acuity (i.e. presbyopia and sensorineural hearing loss) 

Teaching

Postgraduate:

I teach on the MRes Research Methods courses in Psychology Neuroscience and Animal Behaviour. These share statistics and Professional Development modules and include subject-specific seminars and workshops from staff across the Schools of Psychology and Biology. Students complete an empirical dissertation in the 2nd semester, where they’re encouraged to develop professional research skills with a supervisor from staff at the Department of Neuroscience Psychology and Behaviour.

Undergraduate:

I teach Selective Attention on the 1st year course, "Introduction to Sensation Perception and Cognition." My teaching on the 2nd year course "Information Processing and Cognition" builds on my first-year courses and introduces the concepts of cognitive models using Signal Detection and Bayesian theories. I lead a 3rd year "Advanced Cognitive Neuroscience" course, which focusses on the use of methods such as neuroimaging, lesion studies, EEG and single-cell physiology in contemporary Psychology and Cognitive Neuroscience research. 

Press and media

I can be contacted to discuss questions relating to my research interests in perception and cognition.

Activities

I am a member of the Experimental Psychology and Psychonomic Societies.

Conferences

I have presented talks at international conferences including:

1) European Conference on Eye Movements (Spain 2019)

2) European Conference on Visual Perception (Italy 2018)

3) Vision Sciences Society (Florida 2016)
