| Abstract(in English) | Order threshold (OT) represents a minimum time interval that is necessary for subject to be able to indicate the correct temporal order between two stimuli. Most interesting is the result for the regime 3ms<Δt<30ms. Here, two individual different events can be discriminated, but their temporal sequence cannot be assigned correctly: a so-called order threshold. In this paper, it is experimentally investigated whether the sensitivities of OT by visual (flicker, 10ms), bone-conducted ultrasound (40kHz, 10ms), auditory (2kHz, 10ms) and tactile (200Hz, 10ms) are influenced by a change heart beating, or not. From the results, it can be said that the sensitivities of visual is affected by blood flow rate, but auditory and tactile are not. |
