Kognitive Psychologie, Wahrnehmung und Methodenlehre


Research Interests

  • embodied cognition
  • mental representation of numbers, space and time
  • relationship between cognitive processes and eye movements (incl. microsaccades and pupil size)
  • self-motion and vestibular perception
  • how to improve cognitive performance
  • neglect and pseudoneglect
