In stamnosslin/alexis108: Data from Experiment on Discrimination Suppression

This is data from an experiment with one participant (male, 53 year old male). The listener was tested totally 60 days, 13 sessions each day, to test if it is possible to improve the ability to lateralize lag clicks based on inter-aural determine i each on a separate day, measuring level (ILD) differences. The lag clicks were preceded by a lead click with no ILD. The time separation of lead and lag clicks varied between 0 and 18 ms. The lag-click always had an inter-aural level difference of 10 dB and no inter-aural-time difference. For details, see vignette.
