| Abstract(in English) | When we step in stopped escalator, we strongly feel odd sensation called "IWAKAN" in Japanese. Previous study argued that one could not suppress the motor program for "moving escalator" regardless of full awareness of escalator condition (i.e. escalator is stopped) and that the discrepancy between predicted and actual sensory feedback triggered an odd sensation. Furthermore, some could argue that structural nonuniformity of stopped escalator (i.e. the first step is shorter than other steps) caused clumsiness, and this clumsiness induced IWAKAN. We examined these possibilities by comparing the performance to stopped escalator with those to moving escalator and to the wooden stairs which duplicated the structure of stopped escalator. Our results did not support these possibilities. Specifically we correctly recognized the state of the escalator and adequately performed our action before stepping in stopped escalator. Once stepped in stopped escalator, drastic posture forward sway was observed. This sway was not observed in the performance to wooden stairs. These results suggested a new possibility which implied the motor program for moving escalator subconsciously emerge only after we stepped in stopped escalator. We also analyzed the participants' report of IWAKAN after stepping stopped escalator and wooden stairs. Participants felt no IWAKAN after stepped in wooden stairs. On the contrary, when stepped in stopped escalator, they felt IWAKAN, and we identified the kinematic index correlated with participants' report of IWAKAN. |
