Computational Psychology

This area combines experimental psychology with advanced data analysis, computer simulation, and mathematical modeling. On the basis of well-defined theoretical concepts, computational approaches can provide a unifying language and methodology that can be used across disciplines ranging from neurobiology to cognitive science, systems biology, and information technology. Research in this area focuses on the computational basis of vision in particular. A central interest concerns computer vision and the computational modelling of vision using neurobiological principles. Cutting-edge research in this area has thus far examined dynamic modelling of human faces, with applications in object tracking and people detection (such as detection of abnormal behaviour), human gesture recognition, computer modelling of colour vision in insects, the development of intelligent imaging systems, semantic modelling of human movement, and the development of spatial vision models.
