Perception and cognition laboratory

The laboratory focuses on various aspects of human perception and cognition. We investigate how the brain analyzes and interprets complex auditory and visual stimuli that our senses extract from the surrounding environment. In our research, we use behavioral experiments, computational modeling, and neural imaging. The basic science that we perform has many applications in fields such as hearing aids, auditory displays, human-computer interaction, virtual environments, and machine perception.

Research infrastructure

The laboratory is equipped with sound attenuating booth and with various devices for presentation and recording of auditory stimuli (audio processor, multichannel soundcards and amplifiers, set of 24 loudspeakers, variety of headphones and microphones), with systems for tracking human behavior (eye-tracker, electromagnetic position tracker), for measuring brain activity (64-channel EEG system) and with PCs and laptops with software for preparation and performing behavioral experiments and for data collection and analysis.
