معرفی
Thorsten Hansen is a Professor in the Department of General Psychology at Justus Liebig University Giessen, Germany. His research focuses on human color vision using psychophysical methods, computational modeling, and natural scene statistics to understand the principles of color processing and visual perception.
Dr. Hansen received his Ph.D. in Computer Science from the University of Ulm in 2002 and a Diploma in Computer Science with distinction from the Technical University of Braunschweig in 1997. His academic journey bridges computer science and psychology, creating a unique interdisciplinary approach to vision science.
Hansen's research centers on color vision mechanisms, particularly how color contributes to edge detection, contour integration, and object recognition in natural scenes. His work explores higher-order color mechanisms, color constancy, and the influence of memory on color appearance. He has demonstrated that memory significantly modulates color perception, famously showing that even black-and-white bananas still appear yellow due to our memory of their typical color. His research combines experimental psychophysics with computational modeling to understand both early and higher-level visual processing.
Analysis of Hansen's publication record reveals a consistent focus on color vision mechanisms with increasing emphasis on natural scene statistics and real-world applications. His work spans from fundamental neural mechanisms to applied perception research, with a strong emphasis on how color processing contributes to object recognition and scene understanding. Recent publications show continued innovation in understanding the relationship between color, form, and object knowledge in visual perception.

Hansen has supervised numerous doctoral, diploma, and bachelor students, with research topics spanning color constancy, visual illusions, chromatic discrimination, and neural models of vision. His teaching includes courses on visual perception, color vision, and psychophysical methods. As a reviewer, he contributes to major vision science journals and the Deutsche Forschungsgemeinschaft (DFG). Hansen has organized symposia on color vision and presented his work internationally, demonstrating his active engagement with the global vision science community.
His laboratory combines psychophysical experimentation with computational modeling to investigate the principles of early and higher-order mechanisms of color processing. Research focuses on understanding the number and nature of higher-order color mechanisms and how they contribute to visual perception in natural environments.
