Publisher's Synopsis
Excerpt from A Study in Reaction Time and Movement
Since the question of reaction time is only subsidiary to our real problem, it will not be necessary to give in this paper an account of its rather extensive literature. References, however, to the various accounts of the literature of reaction time will be given in the bibliography. The motor discharge by which the reaction is made has been studied but little. Most of the pre vious investigations in this field of research have been concerned separately with one or the other of the two phenomena into whose relation we now inquire. Movement has been given a great deal of attention in studies of fatigue. The perception of movement and its accuracy have also been the subject of much research.
In a paper communicated to the Royal Society of Lon don,1 Dr. William R. Jack presented a study of the velocity of various finger movements for people of different pursuits and ages. No comparison of the velocity of movement with the time of reaction was made. Only the speed of movement was studied and its variation according to the age and ordinary life of the subject.
