Journal Of Experimental Psychology Vol 5 Classic Reprint

Excerpt from Journal of Experimental Psychology, Vol. 5 Records were made during the first year upon a kymograph with the Jaquet marker registering time in one-second periods. During the second year a foot-pierson telegraph recorder was substituted for the kymograph and a pendulum with electric contacts was used, in place of the Jaquet. It also registered in one-second periods. In reading the records the right and wrong reactions were first grouped into five-second, periods for analysis. As it is impractical to give the actual records, two Specimens for eight minutes' work are given in Chart I. These were selected from the work of subject G who showed a greater variation in his reactions than any other subject. Four items are of importance in every record: the averages for the right and the wrong reactions and the variation from these averages. Chart I. Illustrates these features. The average Of right reactions per five-second period on the eighth day is as compared with for the fourth, while the average for wrong reactions has risen on the fourth day to 8 5 from that of 33 for the eighth day. Moreover the variations from the averages has noticeably increased in the records of the fourth day. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
