Cognitive Neuroscience

Our lab studies the relationship between human behaviour and its underlying cognitive processes/neural mechanisms, using a variety of approaches including computational modeling and cognitive neuroscience (with behavioral, eye movement, and EEG/ERP measures).

Research Topics

Our current research topics include (but not limited to) visual perception and cognition and psycholinguistics, as listed below:

  • Eye Movement analysis with Hidden Markov Models, EMHMM toolbox available! (In collaboration with Dr. Antoni Chan at City University of Hong Kong)
  • Deep Neural Network + Hidden Markov Model (DNN+HMM) for modeling eye movements in visual cognition
  • Face and visual word recognition
  • Eye movements in audiovisual information processing
  • Learning changes in perceptual expertise acquisition
  • Music notation reading expertise
  • Asymmetries in visual perception
  • Eye movements in reading


The department of Psychology currently has an Eyelink 1000 eye tracker, a Tobii eye tracker, and a 64-channel ANT EEG system. In addition, our lab has a portable SMI Red-n eye tracker.
