Tests of Quickness.

The tests of reaction time and quickness in sparring made by Dr. Fitz last year in the physiological laboratory will be continued this year. In addition to these, a "Visual location apparatus for testing manual quickness and accuracy" has been devised. The machine consists of a moving carriage which is placed in different positions behind a screen. The screen is suddenly dropped and the subject strikes as quickly and accurately as possible a white spot in the centre of the carriage. The time from the dropping of the screen to the hitting of the dot is measured in hundredths of seconds by a pendulum chronometer and the error of the blow to the right or left of the center, is registered automatically. This apparatus makes it possible to test two qualifications most necessary for a good boxer, fencer, football or tennis player, that is, quickness of sight and accuracy of motor response.

A large number of tests on these pieces of apparatus are desired, both of men practiced in the various athletic sports and of those who have no special aptitude for, or training in them. It is hoped that a sufficient number of men may respond to make a comparison on basis of practice and ability possible. These tests will be carried on in the Physiological Laboratory of the Lawrence Scientific School, from 2.30 to 4.30, on Mondays, Wednesdays, Thursdays and Fridays in January.
