Visual perception and action

Visual perception and action

The brain takes the pattern of light falling on the retina and carries out the staggeringly complex processing required to support the wide range of behaviours needed in everyday life.

Our research investigates the processing of information from the eye to perceive important properties of the outside world such as colour, location, shape, motion and time of day.

We consider how this visual information determines what we attend to and guides the movement of our eyes and body, and how it is integrated with information from the other senses.

Research in our group addresses fundamental science, as well as having practical applications such as the design of software, optical devices and lighting. 

Our research also addresses how visual perception is affected by ageing and conditions such as age-related macular degeneration, Autism and Parkinson’s disease, with implications for understanding symptoms as well as developing interventions and adaptations.

We use the following methodologies:

  • Visual psychophysics
  • Reaction times
  • Computational modelling
  • Eye, head and limb tracking
  • Pupillometry
  • Immersive virtual reality
  • EEG and Visual Evoked Potentials
  • Functional and structural Magnetic Resonance Imaging (MRI)
  • Multielectrode recording
  • Dark adaptometry
  • ElectroretinogramsOpto- and chemogenetics
  • Engineering approaches
  • Image processing
