Cell phones dangerous for child pedestrians, UAB study finds

BIRMINGHAM, Ala. – Children who talk on cell phones while crossing streets are at a higher risk for injuries or death in a pedestrian accident, said psychologists at the University of Alabama at Birmingham (UAB) in a new study that will appear in the February issue of Pediatrics.

"Cell phones clearly offer convenience and safeguards to families, but they also may pose risk," they said, "particularly when children attempt to multitask while conversing on the cell phone and have reduced cognitive capacity to devote to potentially dangerous activities such as crossing streets."

For the study, researchers used a virtual reality software program and three screens to display an actual Birmingham-area crosswalk with simulated vehicles of different sizes traveling on the virtual street. The psychologists found that all of the children – even those who were experienced with talking on cell phones, crossing streets or rated as highly attentive – were more likely to exhibit risky behaviors when they crossed the virtual street while talking on a cell phone.

Specifically, it took the children who were on a cell phone 20 percent longer to begin crossing the street, and they were 43 percent more likely to be hit by a vehicle or have a close call in the virtual environment. In addition, the children looked both ways 20 percent fewer times before crossing the street and gave themselves 8 percent less time to cross safely in front of oncoming traffic when they were on the cell phone.

The study was published by UAB doctoral student Despina Stavrinos, M.S., under the direction of UAB psychologist David Schwebel, Ph.D. UAB graduate student Katherine Byington also contributed to the study.

In this study, 77 children, aged 10-11, completed simulated street crossings in the virtual environment. They were asked to cross the virtual street six times without a cell phone and six times while talking on a cell phone with an unfamiliar research assistant.

The UAB researchers asked the children to cross the virtual street when they believed it was safe. The children stepped from the "curb," onto a pad with a pressure switch electronically connected to a computer, and the system registered the precise moment they entered the "street."

Cell phones are quickly becoming ubiquitous among American schoolchildren, the UAB psychologists wrote. "Commercial interests actively market cell phones for children, and marketing research firms estimate that 54 percent of children 8-12 will have cell phones by the end of [this year,] double the 2006 rate."

Just as drivers should limit cell phone use while driving, pedestrians, and especially child pedestrians, should avoid using cell phone while crossing streets, the UAB researchers said.

More research is needed to determine the impact that texting, listening to mp3 players and talking to peers has on children's ability cross streets safely, they said.

The study was partially supported by the UAB Injury Control Research Center through a grant from the Centers for Disease Control and Prevention and a cooperative agreement with the Federal Highway Administration.

Is technology producing a decline in critical thinking and analysis?

Studies shed light on multi-tasking, video games and learning

As technology has played a bigger role in our lives, our skills in critical thinking and analysis have declined, while our visual skills have improved, according to research by Patricia Greenfield, UCLA distinguished professor of psychology and director of the Children's Digital Media Center, Los Angeles.

Learners have changed as a result of their exposure to technology, says Greenfield, who analyzed more than 50 studies on learning and technology, including research on multi-tasking and the use of computers, the Internet and video games. Her research was published this month in the journal Science.

Reading for pleasure, which has declined among young people in recent decades, enhances thinking and engages the imagination in a way that visual media such as video games and television do not, Greenfield said.

How much should schools use new media, versus older techniques such as reading and classroom discussion?

"No one medium is good for everything," Greenfield said. "If we want to develop a variety of skills, we need a balanced media diet. Each medium has costs and benefits in terms of what skills each develops."

Schools should make more effort to test students using visual media, she said, by asking them to prepare PowerPoint presentations, for example.

"As students spend more time with visual media and less time with print, evaluation methods that include visual media will give a better picture of what they actually know," said Greenfield, who has been using films in her classes since the 1970s.

"By using more visual media, students will process information better," she said. "However, most visual media are real-time media that do not allow time for reflection, analysis or imagination — those do not get developed by real-time media such as television or video games. Technology is not a panacea in education, because of the skills that are being lost.

"Studies show that reading develops imagination, induction, reflection and critical thinking, as well as vocabulary," Greenfield said. "Reading for pleasure is the key to developing these skills. Students today have more visual literacy and less print literacy. Many students do not read for pleasure and have not for decades."

Parents should encourage their children to read and should read to their young children, she said.

Among the studies Greenfield analyzed was a classroom study showing that students who were given access to the Internet during class and were encouraged to use it during lectures did not process what the speaker said as well as students who did not have Internet access. When students were tested after class lectures, those who did not have Internet access performed better than those who did.

"Wiring classrooms for Internet access does not enhance learning," Greenfield said.

Another study Greenfield analyzed found that college students who watched "CNN Headline News" with just the news anchor on screen and without the "news crawl" across the bottom of the screen remembered significantly more facts from the televised broadcast than those who watched it with the distraction of the crawling text and with additional stock market and weather information on the screen.

These and other studies show that multi-tasking "prevents people from getting a deeper understanding of information," Greenfield said.

Yet, for certain tasks, divided attention is important, she added.

"If you're a pilot, you need to be able to monitor multiple instruments at the same time. If you're a cab driver, you need to pay attention to multiple events at the same time. If you're in the military, you need to multi-task too," she said. "On the other hand, if you're trying to solve a complex problem, you need sustained concentration. If you are doing a task that requires deep and sustained thought, multi-tasking is detrimental."

Do video games strengthen skill in multi-tasking?

New Zealand researcher Paul Kearney measured multi-tasking and found that people who played a realistic video game before engaging in a military computer simulation showed a significant improvement in their ability to multi-task, compared with people in a control group who did not play the video game. In the simulation, the player operates a weapons console, locates targets and reacts quickly to events.

Greenfield wonders, however, whether the tasks in the simulation could have been performed better if done alone.

More than 85 percent of video games contain violence, one study found, and multiple studies of violent media games have shown that they can produce many negative effects, including aggressive behavior and desensitization to real-life violence, Greenfield said in summarizing the findings.

In another study, video game skills were a better predictor of surgeons' success in performing laparoscopic surgery than actual laparoscopic surgery experience. In laparoscopic surgery, a surgeon makes a small incision in a patient and inserts a viewing tube with a small camera. The surgeon examines internal organs on a video monitor connected to the tube and can use the viewing tube to guide the surgery.

"Video game skill predicted laparoscopic surgery skills," Greenfield said. "The best video game players made 47 percent fewer errors and performed 39 percent faster in laparoscopic tasks than the worst video game players."

Visual intelligence has been rising globally for 50 years, Greenfield said. In 1942, people's visual performance, as measured by a visual intelligence test known as Raven's Progressive Matrices, went steadily down with age and declined substantially from age 25 to 65. By 1992, there was a much less significant age-related disparity in visual intelligence, Greenfield said.

"In a 1992 study, visual IQ stayed almost flat from age 25 to 65," she said.

Greenfield believes much of this change is related to our increased use of technology, as well as other factors, including increased levels of formal education, improved nutrition, smaller families and increased societal complexity.
