Predictive processes in motor-sensory interactions

The world we perceive is an active interpretation of the information that arrives at our senses. A key factor in this interpretative process is prediction. We are interested in understanding the neural mechanisms that support predictive processing, and how they influence perception. A particularly special kind of sensory predictions arise from our own motor behavior. This is because efficient sensory processing necessarily needs to take into account the sensory consequences of the organisms’ motor actions. Therefore, motor commands are a powerful source of sensory predictions. In our research, we ask participants to deliver auditory stimuli to themselves to study self-generation effects: the altered neural and perceptual processing of self-generated stimuli related to action execution. We are interested in understanding how self-performed actions modulate perceptual processing and sensory responses, and how this modulation influences other functions such as the sense of agency, attention or memory.
