In 1846, Ernst Heinrich Weber described the linear relationship between stimulus intensity and the perceived stimulus change. Assuming that this linear relationship is independent of the stimulus intensity, Gustav Theodor Fechner characterized the sensation of a stimulus with the aid of a logarithmic relationship between intensity strength and absolute threshold. Thereby Fechner regarded as the founder of psychophysics, which includes the sensory modalities of the absolute threshold, sensory intensity, stimulus identification and attraction scaling.
We use classical and modern methods of psychophysics for the characterization of perception and possible changes in tactile and visual Stimuli.
Our labs can be found in rooms NB 3/17, NB 3/88, and NB 3/90.
The Institut für Neuroinformatik (INI) is a central research unit of the Ruhr-Universität Bochum. We aim to understand the fundamental principles through which organisms generate behavior and cognition while linked to their environments through sensory systems and while acting in those environments through effector systems. Inspired by our insights into such natural cognitive systems, we seek new solutions to problems of information processing in artificial cognitive systems. We draw from a variety of disciplines that include experimental approaches from psychology and neurophysiology as well as theoretical approaches from physics, mathematics, electrical engineering and applied computer science, in particular machine learning, artificial intelligence, and computer vision.
