Here is the data:

A Bassin Timer is a device that measures an individual's ability to estimate the speed of a moving light and anticipate its arrival at a designated point. The Bassin timer is a ten foot long row of lights that is controlled by a variable speed potentiometer. In the experiment, the sequence of lights travelled down the track at a rate of five miles per hour. The subject was instructed to anticipate the arrival of the light at the end of the track and swing a plastic bat across a light beam that was aligned with the end of the track to record his or her time. An automatic timing device measured the difference between the time of arrival of the light and the time the light beam was broken. A negative sign denoted that the bat broke the light beam before the light actually arrived, and a positive sign denoted the bat broke the light beam after the light arrived. After the first trial some subjects were randomly selected to receive training that it was thought would improve the tracking. A second trial was then recorded for all subjects.
