At the Olympic-level of competition, even the smallest factors can make the difference between winning and losing. For example, Pelton (1983) has shown that Olympic markspersons shoot much better if they fire between heartbeats, rather than squeezing the trigger during a heartbeat. The small vibration caused by a heartbeat seems to be sufficient to affect aim. A sample of n=12 Olympic markspersons fires a series of rounds while a researcher records heartbeats. For each marksperson, a scores is recorded for...
