How common is teen sexting?Last week we reported on a new study of more thanfifteen hundred Internet users age ten to seventeen.It found that only two and a half percent of themhad sexted in the past year.It also found that only one percent of the imagesmight violate child pornography laws.That study came from the University of New Hampshire.But another new report suggests much higher rates.Both studies defined "sexting" only to meansending or receiving naked pictures.Psychologist Jeff Temple is an assistant professorat the University of Texas Medical Branch in Galveston.JEFF TEMPLE: "We found actuallyabout twenty eight percent of teens had sexted."Mr. Temple says reports from medical officesand school officials support that finding.JEFF TEMPLE: "One of the authors that will be on our paper with our data is a pediatrician.And he certainly sees this in his office.And from talking to school personnel and teens themselves,it certainly seems like it's happeningquite a bit more frequent than the one percentreported in the New Hampshire study,and more in line with what we found in terms ofabout one in four kids have sent a sext."And he says the behavior was the same for boys and girls.JEFF TEMPLE: "We found that about a third of girlshad sent a naked picture of themselves to another teenand about a third of boys had senta naked picture of themselves to another teen."Sexting is not the only issue involving teens and technology.A recent "Online Family Report"from computer security company Nortoncalled attention to "cyberbaiting" in classrooms.Marian Merritt is the company's Internet safety advocate.MARIAN MERRITT: "Kids may engage in purposely taunting,or teasing, or harassing the teacher,in order to get the teacher to have some kind of reactionor response that they then hope to captureon a cellphone camera, a video,and post online where people can view it.Now this can be incredibly embarrassing and humiliatingand damaging to the reputation of a teacher."Ms. Merritt says Norton surveyed more thantwo thousand three hundred teachers in twenty-four countries.MARIAN MERRITT: "What we were surprised to learnis that one in five teachers globally knows somebodythat it's happened to or has had it happen to themselves."She also did a little research of her own.MARIAN MERRITT: "Just typing in phraseslike 'teacher loses it' and that sort of thing,because the term 'cyberbait' is still relatively unknown.But I was surprised to findthere are lots of these videos out there."The online survey also foundthat seventy percent of young people reportedhaving had a negative experience online.Forty percent rated the experience as serious,including cyberbullying, cybercrimeor being contacted by strangers.And that's the VOA Special English Technology Report,written by June Simms.Tell us if you or someone you knowhas experienced cyberbaiting.Share your comments at 51voa.com,where you can also find part one of this report.Transcripts, MP3s and podcasts of our reportsare also available on our website.
