About Us

The Perception, Action and Cognition Research Group (PAC) is a collection of researchers in the at the University of Lincoln, who undertake research on a broad range of issues, including:

  •  Inferential processes in vision
  • The functions of the frontal cortex
  • Control of human eye movements
  • Visual motion processing
  • Perception of visual art
  • Visual attention in social cognition
  • 3-D vision and action
  • Emotion and memory
  • The role of sleep in memory
  • Visual processing in dyslexic, autistic and neurological populations


We have extensive internal and external collaborations with researchers in social psychology, forensic psychology, neuroscience, animal science, computer science and media studies. We have successfully attracted external funding from Leverhulme Trust, EPSRC, ESRC, Nuffield Foundation, Royal Society, Home Office and NHS. The Perception, Action and Cognition Research Group has several dedicated laboratories and a range of state-of-art specialised equipment.

Psychophysics labs

The psychophysics labs are equipped with:

  • Two Cambridge Research Systems (CRS) ViSaGe visual stimulators
  • A CRS Bits# system
  • A ViewPixx Lite/3D system
  • Devices for light measurement and display calibration, such as a Jeti spectroradiometer and Minolta photometer

Eye Tracker Labs

The eye tracker labs house a number of eye movement monitoring and recording systems, including:

  • Tobii 2 and Positive Science head-mounted portable eye trackers
  • An Eyelink 1000 eye tracker
  • A Fourward Technologies Generation 5.5 Dual Purkinje Image eye-tracker plus control system
  • A CRS High-Speed Video Eyetracker Toolbox
  • An Eye Tribe tracker

EEG & TMS Labs

The EEG and TMS labs are equipped with:

  • A 64-channel ActiveTwo EEG set-up with BrainVision Analyzer
  • a Medtronic MagPro X100 high-performance magnetic stimulator that is used in conjunction with a Zebris guidance system

Psychophysiological Recording Lab

The psychophysiological recording lab houses BIOPAC equipment for the measurement of skin conductance and heart rate.

Ultrasonography Lab

The functional Transcranial Doppler (fTCD) ultrasonography lab houses the DWL Doppler-Box TM X system, complete with Doppler M-Mode recording and bi-lateral insonation capabilities for neuroimaging the cerebral vascular system in real-time during cognitive tasks.

Sleep Lab

The sleep and cognition lab is equipped with a 32-channel Embla N7000 polysomnography system and two Actiwatch 2 actigraphy systems for measuring sleep structure.

General / Mobile

The School has a mirror stereoscope for stereovision experiments etc (e.g. disparity, motion in depth, binocular rivalry, continuous flash suppression).
