Think the ump made the wrong call? Think again

Just like sound delay with fireworks, you might see a play before you hear it.
October 24, 2018

New ASU research shows that in baseball, viewing distance from a play is critical —and fans in the stands aren't as accurate as umps

The game of baseball unfolds slowly, over nine innings and over the course of three hours or more — and yet it can reach a critical junction in a blink of an eye. A player’s foot hits the base just as the ball is heard hitting a mitt. The ump yells “Yer out!” And fans in the stands begin to question the ump's judgement.

Can it be that he simply didn’t see the play? Or is his judgment clouded by the roar of the crowd? Is he biased because that same player challenged a previous call? Or is he really as blind as they say he is?

New research from Arizona State University is showing that when it comes to the bang-bang plays in baseball, viewing distance from the play is critical for judging what actually happened. In other words, the umpire being much closer to the action is in a better position to make the right call compared with a fan in the stands 100 or 200 feet away. Especially when observers are juggling two sensory-perception tasks simultaneously — in this case seeing a foot touch the bag and hearing the ball strike the mitt.

“The speed of sound is actually quite slow compared to that of light,” said Michael McBeath, an ASU professor of psychology and perception researcher who developed a way to study how distant you sit from the action can affect how you “sense” or experience a big play.

“This is a multi-sensory, often split-second judgement can make a huge difference in the momentum and eventual outcome of the game,” McBeath added. “Considering the big-stage dynamics and closeness of some calls, it’s not surprising that umpires occasionally make mistakes, but this still doesn't explain why they appear to routinely favor calling outs in those close base-runner situations.”

This can be explained simply as a perception illusion based on distance.

McBeath noted that the speed of sound travels only about 1,125 feet per second, “so for a fan sitting 100 or 200 feet away from the action, a sound will be delayed by one- or two-tenths of a second, long enough to clearly change the order in which sights and sounds are experienced.”

McBeath and ASU student R. Chandler Krynen present their results in the early online edition of the Journal of Experimental Psychology: Human Perception and Performance. In “Baseball Sight Audition Fairness Effect (Safe) When Umpiring Baserunners: Judging Precedence of Competing Visual Versus Auditory Events,” McBeath and Krynen explain that the reason why a close play usually looks like the player is out can be explained through the experience of lightning and fireworks.

“Many of us experience a delay when observing a lightning storm or fireworks — we see the flash before we hear the sound,” McBeath explained. “So we wondered if, in fact, the fans in the stands are experiencing a perceptual illusion to favor base runners due to the delay of sound from our vantage.”

To test this, McBeath and Krynen enlisted scores of volunteers to witness runners reaching first base in a close call. They projected life-size images onto a gymnasium wall with observers standing 100 feet and 200 feet away. In addition to varying viewing distance and actual time difference between auditory and visual events, they also varied visual salience of the ball hitting the mitt and they ran several different experiments with stimuli ranging from cartoon shapes to actual baseball videos.

The results confirmed that viewing distance does systematically bias observers to experience the ball as arriving later, moderated by how clearly one sees the ball-mitt collision.

The tests are a practical example of confirming that two observers (here, the close umpire and the distant fan) systematically perceive the same event differently.

“This can serve as a valuable reminder to maintain humility when we disagree with others, knowing that vantage can fundamentally alter how we experience events,” McBeath said. “In this case, the majority of observers are likely to be the distant fans. The research confirms that close observers, like umpires, are more accurate at making multisensory, temporal judgements like safe versus out at first base.”

ASU Library archivists make marginalized history accessible to all

Community members' participation in archiving history is vital.
Latinos make up 30% of AZ's population but appear in less than 2% of archives.
October 24, 2018

Over the next two years, large portions of four of the library's unique archives — putting farmworkers, civil rights and LGBT history in the spotlight — will become available online to anyone, anywhere

In a small office on the third floor of the Music Building — ASU Library archives’ temporary home during the Hayden renovation — a small desktop scanner whirs quietly as beams of bright light wash over the photo enclosed beneath its lid.

While this is happening, Alana Varner enters information about the photo into an Excel spreadsheet: width and height, the date it was taken, where it was taken, who’s in it.

When all the information is entered and the scanning is complete, she lifts the lid, gently extracts the photo with a gloved hand and places it back in its protective Mylar casing. The photo goes back into a folder containing roughly 10 to 15 more like it, which goes back into a box containing 20 to 25 more folders like it, which goes back onto the shelves that line the walls of the room and contain roughly 70 more boxes like it.

Then it’s on to the next box.

Each photo can take up to five minutes to scan. With anywhere from 14,000 to 26,250 photos in the collection she's working on, it's a significant time investment.

Tedious though it may be, this operation is part of a significant three-year project titled “Engaging, Educating, and Empowering: Developing Community-Driven Archival Collections.” Supported by a $450,000 grant from the Andrew W. Mellon Foundation, the project has the goal of giving voice to historically marginalized communities by preserving and improving Arizona’s community archives.

Thanks to the efforts of head project archivist Varner and her team, a large portion of the Bj Bud Memorial Archives, the largest LGBT collection in Arizona, will soon be accessible online, to anyone, anywhere. 

Over the next two years, the grant will also allow for three more of the library's other unique and most consistently utilized archives to be accessed online. They are: the Maricopa County Organizing Project (MCOP) Records, detailing local farmworker and civil rights history from 1960-1990; the League of United Latin American Citizens (LULAC) Collection, which tells the story of the oldest active Latino civil rights organization in the U.S.; and the Alianza Hispano Americana Records, which tells the story of the oldest Latino mutual aid society.

A selection of periodicals and photographs from the Bj Bud Memorial Archives will be on display at an event from 6 to 8 p.m. Thursday, at the Tempe Transportation Center at 200 E. 5th St. The event is free and open to the public.

Historically, Varner said, archivists haven’t done a great job of including the stories of minority communities.

“The goal of this project is both to show these communities that their histories are valuable and worth saving, and to show people in our profession that these communities have been ignored for too long and we need to work with them and make amends for that and build trust,” she said.

As an undergrad at the University of Arizona, Varner had a job in the library’s special collections. That was around the same time the state started seeing proposals to ban ethnic studies and the passage of SB 1070, an anti-illegal immigration measure widely criticized as racial profiling.

It made her wonder how much of what she was witnessing would make it into the annals of recorded history. So she committed to becoming an archivist.

A few years later, while working for Densho, a nonprofit organization in Seattle that collects oral histories and documents related to Japanese-American internment during World War II, Varner met ASU Library archivist Nancy Godoy at a conference for the Society of American Archivists.

Godoy, who grew up in the border town of Yuma, has been an unceasing force for growing ASU Library’s minority-themed archives and community outreach efforts. The pair recognized each other as kindred spirits, and when Godoy got news of the Mellon grant later that year, Varner jumped at the chance to work with her.

In addition to digitizing archival materials to make them more accessible, the grant also supports the formation of a community advisory board, as well as “Archives and Preservation Workshops” and “Digitization and Oral History Days.”

Both Varner and Godoy agree that including the community in the archival process is vital.

“This won’t work if the community isn’t part of it,” Godoy said. “If we don’t do this together, that’s how communities get erased.”

“The whole point is to create community archivists who can do this all themselves.”

Not only are there gaps in information — such as names and places — that community members who were there may be able fill in, they may have their own invaluable pieces to add to the archive. All of that helps to tell a more accurate, inclusive story.

Though the Bj Bud archive is notable because of its size and subject, it mostly tells the story of gay, white males.

“We hope other minority groups — people of color, trans people — within [the LGBT group] will participate and contribute to this archive as well, because we need to widen the scope of perspectives,” Godoy said. “We don’t want to further marginalize people.”

The team is marketing community workshops toward Latinos, African-Americans, LGBT and Asian-Americans based on research that found those ethnic groups to be in need of more historical documentation. At the workshops, participants learn such skills as interviewing techniques, how to record oral histories and photo scanning.

“The whole point is to create community archivists who can do this all themselves,” Godoy said.

Documenting the past can also change the future. Because the archives are now accessible to the public, the project team hopes to see them used in curriculum from K–12 to the college level.

Textbooks are exclusive and therefore biased, they said. The archives consist of primary resources that can be observed and considered objectively.

“This project, for me, just resonates so strongly,” Varner said. “I think it’s something that Arizona really needs. It just seems to be so powerful and meaningful for people to have access to this information.”
