title: Do scores on a tachistoscope test correlate with baseball batting averages?
abstract: BACKGROUND
  Millions of dollars are spent each year by individuals seeking to improve their athletic performance. One area of visual training is the use of the tachistoscope, which measures inspection time or visual recognition time. Although the potential of the tachistoscope as a training tool has received some research attention, its use as a means of measurement or predictor of athletic ability in sports has not been explored. The purpose of this pilot study is to assess the potential of the tachistoscope as a measurement instrument by determining if a baseball player's ability to identify a tachistoscopically presented picture of a pitch is correlated with hitting performance as measured by batting average.
  
  
  METHODS
  Using sport-specific slides, 20 subjects-all non-pitching members of the Pacific University Baseball Team-were administered a tachistoscopic test. The test consisted of identifying the type of pitch illustrated in 30 randomly ordered slides depicting a pitcher throwing four different baseball pitches. Each slide was presented for 0.2 sec. The results of the test were compared with the athlete's previous season's batting average.
  
  
  RESULTS
  A positive correlation was found between an athlete's ability to correctly identify a picture of a pitch presented tachistoscopically and batting average (r=0.648; P<0.01). These results suggest that a superior ability to recognize pitches presented via tachistoscope may correlate with a higher skill level in batting.
  
  
  CONCLUSIONS
  Tachistoscopic test scores correlated positively with batting averages. The tachistoscope may be an acceptable tool to help in assessing batting performance. Additional testing with players from different sports, different levels of ability, and different tachistoscopic times should be performed to determine if the tachistoscope is a valid measure of athletic ability. Implications may also be drawn in other areas such as military and police work.
