https://matteocampagna.com/en/registry/technique/clicker-reaction-time Changes to this claim in Matteo Campagna's evidence registry: its status, its year-by-year history, revisions of the page. en-gb https://matteocampagna.com/en/registry/technique/clicker-reaction-timeAcross skill levels the picture is clear: after the clicker drops, elite archers release sooner than beginners, and beginners sooner than people who have never shot. Inside a group of archers who are already strong, the same rule is hard to see. In the largest sample, thirty-nine elite archers at a World Cup, a shorter reaction goes with higher scores, but the gap between the quickest and the slowest in the group is worth half a point. In eight high-level French archers, arrows scoring eight or less come after a longer reaction than tens, and the same study adds the limitation that changes everything: the difference is there when you look at the group and appears in none of the eight archers taken on their own. Two laboratories, eleven people between them, find no link with score at all, and two reviews conclude that among the elite what predicts performance is not the length of the reaction but how steady it stays from arrow to arrow. Nobody has tried shortening it through training to see what happens to the points.claim:reazione-rapida-clicker:revision:2026-10-08:2Thu, 08 Oct 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaThe doctoral thesis that contains that study adds the comparison between levels on the same measurement set-up, with fifteen archers: between elite and intermediate archers clicker reaction time makes no difference, while within the archer tens come after a quicker reaction than arrows scoring eight or less. Counting the evidence on archers, the supporting results now outnumber the contrary ones, and the two heaviest contrary results come from samples of four and seven people measured before 2013 that nobody has repeated: the status returns to reported. It returns by a narrow margin, and the within-archer part is the same sample as in 2025.claim:reazione-rapida-clicker:history_entry:2026-09-22:2026Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaFor the first time the link is looked for inside a group of elite archers only, and the same study both finds it and takes it apart. In eight high-level French recurve archers, arrows scoring eight or less have a longer clicker reaction time than tens, but the difference appears when looking at the group and emerges in none of the eight archers taken on their own. A result that contradicts itself leaves the status contested.claim:reazione-rapida-clicker:history_entry:2026-09-22:2025Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaSix elite and seven sub-elite archers filmed with a high-speed camera at seventy metres give 146 thousandths of a second against 156: the difference between levels turns up again with a different method and in a new laboratory. It is a group description and does not relate the time to the score of each arrow, so it does not resolve the disagreement and the status holds.claim:reazione-rapida-clicker:history_entry:2026-09-22:2023Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaTwo reviews from the same year line up what exists and correct it at the same time. Four studies agree that a quicker reaction goes with better performance, with typical elite times around one hundred and fifty thousandths of a second. Inside an elite group, though, what predicts the score is not the mean time but how steady it stays from arrow to arrow. The reviews photograph the disagreement without adding new samples, so the status does not move.claim:reazione-rapida-clicker:history_entry:2026-09-22:2022Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaTwo new measurements, both weak, leave the status where it is. A skilled archer measured on force plates reacts in 161 thousandths of a second with his habitual draw, matching elite values, and in 304 with a straight draw: reaction time changes with the technique used, not only with the archer's level. In ten boys aged fifteen to seventeen, reaction time measured in a laboratory relates to score in one of the eight combinations measured, which is what chance alone would give.claim:reazione-rapida-clicker:history_entry:2026-09-22:2020Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaThe sample changes scale: thirty-nine elite archers from four countries at a World Cup, and a quicker clicker reaction enters the score predictors alongside draw force and sway speed. It is the first supporting evidence measured inside a group of elite archers only, but the effect is worth half a point between the quickest and the slowest, and the two contrary results from 2010 and 2012 still stand with nobody having repeated them. The status stays contested.claim:reazione-rapida-clicker:history_entry:2026-09-22:2017Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaA third group, on fifteen archers of mixed level with thirty shots each, repeats the same thing from inside the single archer: the predictors of distance from the centre include each shot's deviation from that archer's usual clicker-to-release time, not the length of the time. The status stays contested and the question is reframed: not how quick the reaction is, but how closely it repeats.claim:reazione-rapida-clicker:history_entry:2026-09-22:2016Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaThe contrary result becomes independent: seven archers from the German national squads measured with an acoustic system show that the mean time between clicker and release, between 144 and 176 thousandths of a second, does not explain their mean score. Only its steadiness enters the model. The status stays contested, but the weight shifts, because among archers who are already expert, quickness does not seem to count.claim:reazione-rapida-clicker:history_entry:2026-09-22:2012Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaThe second publication of the same experiment reports the same 108 shots with figures identical to the decimal, so it counts once: it is not an independent confirmation and the status does not change. Up to here the contrary results come from a single sample of four people, published twice.claim:reazione-rapida-clicker:history_entry:2026-09-22:2011Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaThe first measurement within a single archer arrives, and it goes the other way: in four elite women archers the clicker reaction time is identical on arrows scoring eight, nine and ten, 143 thousandths of a second against 142. In one of them the reaction really is quicker on the better arrows, but the comparison does not survive the test. With the supporting evidence from 2003 and this contrary result, the studies on archers no longer point the same way: contested.claim:reazione-rapida-clicker:history_entry:2026-09-22:2010Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-time#storiaIn twenty archers from the Turkish national squad the clicker reaction measured in the field averages under two tenths of a second, but ranges from a tenth to half a second from archer to archer. The figure says how long the interval is and how much it varies, without relating it to the score: the status stays reported.claim:reazione-rapida-clicker:history_entry:2026-09-22:2005Tue, 22 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/clicker-reaction-timeclaim:reazione-rapida-clicker:new_claim:2026-08-31:riportatoMon, 31 Aug 2026 08:00:00 GMT
