Xinhua News Agency, Washington, January 20 (Reporter Zhou Zhou) Statistics show that up to 20% of children will experience anxiety and depression, but these psychological problems are often difficult to be discovered in time, so that the best intervention opportunity is missed. American researchers have used artificial intelligence to develop a child behavior screening tool that can quickly and accurately identify such problems.
Researchers at the University of Vermont and the University of Michigan introduced in the new issue of the journal Science Public Library·Integration that they use wearable motion sensors to collect child behavior data and then use machine algorithms for assessment screening.
During the test, 63 children were led into a darkroom. The researchers first prompted them to see something, be careful not to wake them up, then they quickly uncovered the cloth on a glass container and pulled out a fake snake. These kids are playing.
Often, researchers will diagnose whether they have psychological problems by watching process videos, assessing children's behavior and language. In this test, the researchers also collected sensor monitoring data and used machine algorithms to analyze children with anxiety and depression, resulting in an accuracy rate of 81%, which is superior to the commonly used parent questionnaire. .
The algorithm found that children are critically aware of potential signs before they see snakes. Children with anxiety or depression are more anxious than other children in the face of potential uncertainties, and are more inclined to avoid, while sensors and algorithms can help Come to a conclusion.
Alan McGinnis, a clinical psychologist at the University of Vermont, says tasks that used to be trained for weeks and analyzed for months can now be completed in a matter of minutes. After obtaining the first-stage behavioral data of the child's test, the machine algorithm can determine whether the child has psychological problems such as anxiety or depression in only 20 seconds.
Researchers say early intervention in psychological problems is critical because children's brains are highly malleable and respond well to treatment. Without timely intervention, these children are at higher risk of drug abuse and suicide in adulthood.
