An Observation on Psychological Effects of Meteorological Elements

Abstract

As the measure of mental laxness the ratio of the number of articles left in the city-ears to that of the total passengers was calculated for each day. From January to December 1933, the daily passengers amounted to about one million and a half, white the daily number of articles left was some two hundred in Tokyo. The correlations of the ratio with the meteorological elements were studied and the relative humidity was found to be the most effective. The coefficient of correlation was computed: in Tokyo r=0.64 and w=0.027 (January-December, 1933) and in Yokohama, r=0.42 and w=0.030 (April 1932-March 1933) where
In addition, it was ascertained that the sudden increase of humidity and the decrease of the atmospheric pressure generally precede the increase of the above-mentioned ratio. The data from the city of Osaka were also brought under the discussion.
