“Depending on how familiar people are with these songs, it could lead to an even worse impairment in their cognitive performance,” she said. Thus, people who use popular songs as a personal ringtone may be increasing the odds their cell phone rings will be more distracting.
“It slowed down their decision-making performance for a longer time than even a standard ringtone.” “When we played the fight song as part of our lab experiments, the distraction factor lasted longer,” Shelton said. The song also became a popular cell phone ringtone. The song, an instrumental version of the LSU fight song, was then being played incessantly around campus as LSU football made its fall 2007 run to the national college championship. In this phase of the experiment, students in a laboratory were tested on simple word-recognition tasks while exposed to a range of auditory distractions, including irrelevant tones, standard cell phone rings and parts of a song very familiar to most LSU students. Perhaps most surprising, the study found that unexpected exposure to snippets of a popular song, such as those often used as ringtones, can have an even-longer-lasting negative impact on attention. The study explores cognitive differences in how we respond to auditory distractions, specifically whether we process these interruptions using a voluntary, top-down, executive-level shift in attention or as a more reflexive, automatic and involuntary reorientation of attention. Her co-authors in the LSU psychology department include Emily Elliott, Sharon Eaves and Amanda Exner. Titled “The distracting effects of a ringing cell phone: An investigation of the laboratory and the classroom setting,” the study was conducted at Louisiana State University, where Shelton received her doctoral degree. “These seemingly innocuous events are not only a distraction, but they have a real influence on learning.” “Many of us consider a cell phone ringing in a public place to be an annoying disruption, but this study confirms that these nuisance noises also have real-life impacts,” Shelton said. Students scored even worse when Shelton added to the disturbance by frantically searching her handbag as if attempting to find and silence her ringing phone. Students tested later scored about 25 percent worse for recall of course content presented during the distraction, even though the same information was covered by the professor just prior to the phone ring and projected as text in a slide show shown throughout the distraction. Students exposed to a briefly ringing cell phone scored 25 percent worse on a test of material presented before the distraction. The study includes an experiment in which Shelton poses as a student seated in the middle of a crowded undergraduate psychology lecture and allows a cell phone in her handbag to continue ringing loudly for about 30 seconds. “In any setting where people are trying to acquire knowledge and trying to retain that information in some way, a distraction that may just seem like a common annoyance to people may have a really disruptive effect on their later retention of that information,” said the study’s lead author, Jill Shelton, a postdoctoral psychology fellow in Arts & Sciences at Washington University in St. Now, a new study in the Journal of Environmental Psychology finds that just the ring of a cell phone may be equally distracting, especially when it comes in a classroom setting or includes a familiar song as a ringtone.
PHONE RINGTONES DRIVERS
A flurry of recent research has documented that talking on a cell phone poses a dangerous distraction for drivers and others whose attention should be focused elsewhere.
