Measurement of Order Threshold by Two-Pulse Stimuli synchronized by Earlobe Photoplethysmogram with Senses Fatigue Measurement Device
Sho Arai, Kenji Furihata (Shinshu Univ.) EA2009-64
Abstract (in Japanese) (See Japanese page) 
(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 3 ms < &#8710;t < 30 ms. 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, 10 ms), bone-conducted ultrasound (40 kHz, 10 ms), auditory (2 kHz, 10 ms) and tactile (200Hz, 10 ms) 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.
