The processing of spatial frequencies through time in visual word recognition
Clémence Bertrand Pilon, Martin Arguin · FENS Forum 2024
Spatial frequencies (SF) optimal for word recognition are well established. However, other classes of stimuli demonstrate a rapid temporal evolution of SFs most useful for visual recognition. (Bar,2003,JcogNeurosci) This study aims to assess the time course of SF processing in visual word recognition. Word images were filtered like so: 1.2, 2.4, 4.8, and 9.6 cycles per degree, with 200 ms exposure duration and variyng signal-to-noise ratio (SNR; signal=image; noise=white noise) according to a random sampling function integrating sine waves with 5-55 Hz frequencies in steps of 5 Hz.
