Small study found they tended to do better at

WEDNESDAY, May 1 (HealthDay News) -- Using a kid-friendly robot during behavioral therapy sessions may help some children with autism gain better social skills, a preliminary study suggests.

The study, of 19 children with autism spectrum disorders (ASDs), found that kids tended to do better when their visit with a therapist included a robot "co-therapist." On average, they made bigger gains in social skills such as asking "appropriate" questions, answering questions and making conversational comments.

So-called humanoid robots are already being marketed for this purpose, but there has been little research to back it up.

"Going into this study, we were skeptical," said lead researcher Joshua Diehl, an assistant professor of psychology at the University of Notre Dame in Indiana, who said he has no financial interest in the technology.

"We found that, to our surprise, the kids did better when the robot was added," he said.

There are still plenty of caveats, however, said Diehl, who is presenting his team's findings Saturday at the International Meeting for Autism Research (IMFAR) in San Sebastian, Spain.

For one, the study was small. And it's not clear that the results seen in a controlled research setting would be the same in the real world of therapists' offices, according to Diehl.

"I'd say this is not yet ready for prime time," he said.

ASDs are a group of developmental disorders that affect a person's ability to communicate and interact socially. The severity of those effects range widely: Some people have mild problems socializing, but have normal to above-normal intelligence; some people have profound difficulties relating to others, and may have intellectual impairment as well.

Experts have become interested in using technology -- from robots to iPads -- along with standard ASD therapies because it may help bridge some of the communication issues kids have.

Human communication is complex and unpredictable, with body language, facial expressions and other subtle cues coming into the mix, explained Geraldine Dawson, chief science officer for the advocacy group Autism Speaks.

A robot or a computer game, on the other hand, can be programmed to be simple and predictable, and that may help kids with ASDs better process the information they are being given, Dawson said.

"Broadly speaking," she said, "we are very excited about the potential role for technology in diagnosing and treating ASDs." But she also agreed with Diehl that the findings are "very preliminary," and that researchers have a lot more to learn about how technology -- robots or otherwise -- fits into ASD therapies.

For the study, Diehl's team used a humanoid robot manufactured by Aldebaran Robotics, which markets the NAO robot for use in education, including special education for kids with ASDs. The robot, which stands at about 2 feet tall, looks like a toy but it's priced more like a small car, Diehl noted.
