The avalanche of complaints about that missed call and
others during the largest soccer tournament in the world raised the
philosophical question of whether instant-replay technology improves games or
turns them into soulless events run by a bank of blinking lights.
Scientists who study the human brain say it is surprising
that bad calls do not happen more often.
"Despite all of the apparent surprise that the
referees would be blowing calls, especially at crucial points, from a
psychological standpoint this is what we would expect," said David Meyer,
director of the University of Michigan's Brain, Cognition and Action
Laboratory.
"It's like every once in a while you draw the ace of
spades," the psychology professor added. "It's going to happen."
Questions about the capacity of the human brain to judge action on the sports
field are not limited to conversations at the local bar, but are examined by
neurobiologists and psychologists using such measures as "relay
latency," "perceptual fluency" and "speed-accuracy trade-off
curve."
While it is easy for fans to throw up their hands in
disgust at a missed call and curse the referee, they need to realize that
officials are weighing up actions, which happen in fractions of a second,
experts say.
"Human beings are never going to be perfect at
making calls," said Gary Marcus, a professor of psychology at New York
University. "Our memories just aren't cut out to allow us to be perfect
referees.
"Our eyes work a lot like cameras but our memories
don't work anything like an SD (secure digital) card," Marcus, author of
the book "Kluge: the Haphazard Construction of the Human Mind," said,
referring to memory cards used in digital cameras.
"We can't literally play back what we just
saw."
Making it tougher was the fleeting nature of moves in
sport, said Emilio Salinas, an assistant professor of neurobiology at Wake
Forest University Baptist Medical Center who helped to write a paper entitled
"Perceptual decision making in less than 30 milliseconds."
Salinas and fellow authors found that as little as 30
milliseconds of extra viewing time was the difference between a correct and an
incorrect judgment about whether a flashed light had turned red or green.
"Thirty milliseconds is sort of an upper bound on
how fast you can do that kind of discrimination," he said.
Then there is the fact that referees simply cannot see
everything.
University of Michigan's Meyer said the maximum number of
players any one person could carefully track was four, meaning something would
be missed even with multiple referees watching.
When referees do miss a crucial piece of evidence, their
brain will fill in the gaps using past experiences to help them make the call.
"Filling in is really a deeply embedded part of
human consciousness," New York University's Marcus said.
Just as a driver's brain would tell him a car was in his
blind spot even though he could not see it, referees' brains would fill in what
was missing, he said.
Obstructed views or bad angles are supplemented by the
official's past experiences, something that may have happened when a botched
call in early June cost Detroit Tigers pitcher Armando Galarraga a perfect game
in Major League Baseball (MLB).
Scientists and even referees understand that the accuracy
of calls increases with experience. However, additional practice does not
always make perfect.
"You can train your eyes all day long to see as
quick as possible, but we're talking about 300 milliseconds to see a
95-mile-an-hour fastball coming from a professional pitcher's rubber to home
plate," said Kevin Gee, director of the Sports Vision Performance Center
at the University of Houston College of Optometry.
Given the challenges for the human brain, even some
staunch critics of technology to aid referees have changed their minds.
"I don't know if we can get any better at doing what
we do," said retired MLB umpire Don Denkinger, who is remembered for an
incorrect call in the 1985 World Series. "There's no super umpire sitting
out there.
"You have plays that are going to pop up that are
called wrong and if you don't want to use instant replay, you just have to
accept them," added Denkinger, who no longer opposes the use of instant
replays.
After Lampard's no-goal in June, FIFA president Sepp
Blatter apologized for refereeing mistakes at the World Cup and said soccer's
governing body would reopen the debate on goalline technology.
Even the scientists, however, recognize the appeal of the
drama offered by human error.
"In real life, most of the time we do not have the
possibility of engaging in instant replay in order to correct mistakes,"
Meyer said. "By keeping the technology out of play, we make the sport more
traditionally lifelike and in some ways that can enhance the drama."
