title: Free physical movements during waiting while standing and sitting.
abstract: Man's habitual physical movements in a daily life situation while waiting for someone in front of a railway station in either a standing or sitting posture were studied. The free movements of 113 male and 171 female standing subjects and 236 male and 67 female sitting subjects were recorded for a period of three minutes by commentary using a tape recorder. The mean frequency of spontaneous movements was 13.8/min during standing and 14.3/min during sitting, the neck and lower limb movements being frequent in the former and the neck and upper limb movements in the latter. Males smoked, yawned, and crossed their legs more often than females. Any physical movement was most frequently followed by cessation of movements. Kinds of movements following a preceding motion proved almost independent from the type of the preceding one. Most of such movements ended within 2.5 sec, scarcely lasting for longer than 30 sec, while about 90% of the periods of being still were shorter than 15 sec. It is suggested that most of spontaneous physical movements in waiting occurred independently and were intercalated between short pure rest periods.
