Research suggests severe weather will continue, be more variable

More tornadoes will be commonplace by 2080 as a result of a changing climate, according to a new study from UGA geography researchers.

Sound investment

A sold-out house at the Georgia Theatre greeted UGA senior Katie Black in early January as she walked onstage with Gregg Allman. Her job was simple—introduce the legendary rock and blues musician prior to a performance in Athens and thank him for establishing a scholarship that will help fund the remainder of her time at UGA.

$1.44M grant to fund study on link between epigenetics, cancer

A UGA statistics researcher has been awarded a $1.44 million grant from the National Institutes of Health to develop statistical models that one day may be used to predict cancer and other diseases.

$2M NSF grant aims to help attract, train math students

UGA has received a $2 million grant from the National Science Foundation to continue its efforts to educate math majors at both the undergraduate and graduate levels. The grant will be administered over a five-year period.

Retired professor’s art on display at ACC Library

Drivers traveling past the Athens-Clarke County Library on Baxter Street will notice a new, large, colorful structure just near the road. Red, white and blue, this 15-foot sculpture is the latest public artwork by retired UGA Emeritus Professor of Art Robert Clements.

Chemistry researchers develop new drug formulation for cancer treatment

Health forums were abuzz in 2007 with news that a simple, inexpensive chemical may serve as a viable treatment to many forms of cancer. The drug dichloroacetate, or DCA, was touted as a cure-all, but after years of work, scientists still are searching for ways to make the unique treatment as effective as possible.

Symposium to look at medicine with historical lens

"Ancient Medicine and the Modern Physician," a two-day symposium sponsored by the classics department of the Franklin College of Arts and Sciences in collaboration with the Georgia Regents University/UGA Medical Partnership, aims to find relevant historical practices that are useful to modern-day physicians.

New psychology research shows promise for earlier, better dementia diagnosis

Nearly 36 million people worldwide are estimated to currently have dementia. That number is expected to almost double every 20 years. Researchers are working diligently to find better, more accurate methods for earlier diagnosis.

Psychology researchers extend knowledge of visual misperception

Using abstract images instead of real photographs, UGA researchers are one step closer to understanding visual misperceptions and discovering why people experience a phenomenon known as boundary extension.

Boundary extension happens when someone takes a look at a scene, glances away and remembers seeing a more wide-angle view than was actually present. In just a few short seconds, the human brain helps most people extend the scene beyond what actually is seen.

Scientists at the University of Delaware discovered this concept in 1989 when they showed study participants real photographs of 20 scenes for
15 seconds and then had participants draw a picture of what they’d viewed. Ninety-five percent of the drawings included information that wasn’t physically present but would have been just outside the camera’s field of view. This phenomenon consistently has been demonstrated since that time, but researchers have not been able to explain why it occurs.

James Brown, an associate professor in the Franklin College of Arts and Sciences psychology department, and graduate students Benjamin McDunn and Aisha Siddiqui decided to study whether the use of an abstract image—instead of a photograph—would produce different results.

They found that showing subjects geometrical images on random-dot or white backgrounds had similar results. The study was published recently in Psychonomic Bulletin & Review.

Familiarity with an environment or an object may have much less of an effect than previously was thought on whether or not people remember viewing things through a wide-angle lens.

McDunn and Brown now are examining spatial perception by constructing a study in which participants view scenes depicting the real world—with similar object features such as size and spatial attributes—to see if the phenomenon exhibits with the same pattern.

“Spatial vision in general is somewhat enigmatic and difficult to study in isolation,” McDunn said. “Boundary extension may provide a means of determining what characteristics of a stimulus cause us to perceive it as depicting space.”

While researching spatial vision is difficult, Brown said, it’s important to understand more about how people see the world.

 

“Boundary extension,” he said, “seems to be strongly tied to our perception of a continuous spatial expanse around us, knowing a given view depicts a truncated portion of the world, a characteristic that is common to all scenes in the real world.”

Students conduct research as part of NASA program

Ten students from UGA spent the summer using NASA's observational data to explore Georgia's salt marshes, the ecosystem of bearded capuchin monkeys, the effects of debris from fire burning and the impact of a non-native insect on Eastern hemlock trees.
