Brief description of research activities

At the Center for Visual Cognition, visual cognition is investigated by a combination of different methods: experimental techniques from cognitive psychology and psychophysics, mathematical modeling and computer simulation, and analysis of brain activation during performance of visual tasks (functional imaging by use of EEG and related techniques). Researchers at the Center have invented an influential mathematical model for visual attention (Theory of Visual Attention, TVA) and interpreted the model as a neurophysiological theory (a Neural Theory of Visual Attention, NTVA). The model is used for investigating basic attentional deficits associated with conditions such as depression, schizophrenia, and ADHD.

Key words: Vision, Cognition, Attention, Neuropsychological assessment

Research tools and techniques

Psychological experiments, measurement of reaction times and error rates, mathematical modeling, computer simulation, EEG.
