Topic: perceptual biases

Magnitude estimation and stimulus discrimination tasks are affected by perceptual biases that cause the stimulus parameter to be perceived as shifted toward the mean of its distribution. These biases have been extensively studied in psychophysics and, more recently and to a lesser extent, with neural activity recordings. New computational techniques allow us to train spiking recurrent neural networks on the tasks used in the experiments. This provides us with another valuable tool with which to investigate the network mechanisms responsible for the biases and how behavior could be modeled. As

The sensory content and temporal structure of stimuli consistently bias the percept of duration. Previous studies revealed that intervals filled with continuous sensory input are perceived as longer compared to stimuli only marked at their onset and offset, a phenomenon referred to as 'filled duration illusion'. It remains unclear whether these distinct stimulus formats are measured by a common timing mechanism. In our study, we aimed to examine potential differences in the EEG correlates of temporal processing for filled, flanked and empty stimuli. We tested participants in a temporal reprodu
