Researchers at University of Miami revealed that they are looking to develop new ways to predict the occurrence of Autism Spectrum Disorder (ASD) early in children who have a high risk of the condition in order to allow the possibility of early intervention that could lead to better outcomes in future.
Their findings are published in the journal Infancy. The study is one of the first to show that measures of non-verbal communication in children, as young as eight months of age, predict autism symptoms that become evident by the third year of life. The results suggest that identifying children, who are having difficulties early enough, can enhance the effects of interventions. "For children at risk of developing an ASD, specific communication-oriented interventions during the first years of life can lessen the severity of autism's impact," says Daniel Messinger, professor of Psychology in the College of Arts and Sciences at UM and principal investigator of the study.Before children learn to talk, they communicate non-verbally by using eye contact and gestures. These abilities are called referential communication and are in development by eight months of age. However, "impairments in non-verbal referential communication are characteristic of older children with ASD," says Caroline Grantz a doctoral candidate in the Department of Psychology at UM and co-author of the paper.In the study, a team of researchers tested two groups of children. One group was at high-risk for ASD and the second group was at low-risk. The evaluations took place during 15 to 20 minutes sessions, at 8, 10, 12, 15 and 18 months of life. The team measured the development of three forms of non-verbal communication:
- Initiating Joint Attention (IJA) - the way an infant shows interest in an object or event to a partner. For example, making eye contact and pointing to show a toy.
- Initiating Behavioral Requests (IBR)-the manner in which an infant requests help from a partner, by making eye contact to request a toy, reaching toward, pointing to, or giving the examiner a desired toy.
- Responding to Joint Attention (RJA)-the way infants respond and follow the behavior of a partner. For example, when the examiner points to something and the child follows the experimenter's gaze to look at that an object.The results show that lower levels of IJA and IBR growth between eight and 18 months predicted the severity of ASD symptoms for children that had a sibling with Autism.
