Our unisensory training was designed with the same timing structure as the multisensory training in this study but contained only visual stimuli (visual flashes), which had to be judged regarding their synchronicity. Visual stimuli (4 deg. of visual angle) were presented 4 deg. of visual angel underneath and above the fixation mark. There were 120 trials presented pseudorandomly in the training phase (60 times SOA 0 ms condition and 10 times each other SOA condition).
Considering the findings of Powers et al. (2009) (link) as well as Stevenson et al. (2013) (link), who demonstrated the necessity of feedback for inducing long-lasting changes in the TBW, we decided to use feedback for our subjects regarding the synchronicity of the stimuli within the SJT training units. Both, the unisensory and multisensory training had duration of approximately four to 5 min depending on the response times of the participants.
All stimuli were presented binaural via loudspeakers placed beside of a high refresh rate monitor (Sony Multiscan G520, 120 Hz) placed in a quiet room approximately 60 cm in front of the subjects. All auditory stimuli were presented at individual subjective level of good audibility. Presentation software (Neurobehavioral Systems, Inc., Albany, CA, United States, version 14.9) was used to control all experiments and collect data.
