Publisher's Synopsis
Excerpt from A Plethysmographic Study of Attention
The following observers shared in the experiments: Drs. Bentley and Baird, Miss Jenkins and Miss Andrus, Messrs. Sa bine and Galloway. Mr. Galloway began to observe with Exp. 57. Miss Andrus did not Observe after Exp. 36. The normal curves of Dr. Baird', Miss Andrus, Miss Jenkins and Mr. Sabine were recorded for a period of several months prior to the experiments with reactions. The average rates of pulse and respiration, with the mean variation of each, are given in a table. The numbers which enter into these averages were obtained by measuring the number of pulses and respirations for each 10 seconds of each record. The average rate for each record is found by taking the average of the 10 second values. The final average for each observer is made by taking the aver age oi all the records. The mean variation is the average deviation of the average of each record from the average of all the records. The number of records of both pulse and respira tion is also given.
