The sound localization paradigm with auditory spatial processing occurred during the presentation of the 3-s “Bat-ears” sound. For each trial, an auditory cue was presented for 750 ms to indicate the task type: the localization task trial was indicated by a high-tone (peaked at 2,000 Hz) and the differentiation control trial was indicated by a low-tone (peaked at 500 Hz). After 1,750 ms delay, the 3-s auditory stimulus was presented and followed by a 500-ms cue to indicate the preparation for response. Finally, the left time was for the joystick response
