Parent coaching sparks major communication growth in infants with social and communication delays
New research shows social communication improves when support starts before age 1
2025-05-06
(Press-News.org) BALTIMORE, May 6, 2025— A newly published trial from Kennedy Krieger Institute reveals a promising path forward for infants showing early signs of social communication delays.
The study found that targeted coaching for caregivers of infants as young as 8 months significantly enhances babies’ communication and cognitive development. Caregivers in the trial received 16 in-home sessions with a trained developmental psychologist. Strategies included narrating an infant’s actions, such as saying “you rolled the ball,” and choosing toys that support language, attention, and engagement.
This is one of the first trials to evaluate parent-led interventions for infants under 12 months with social delays. Dr. Rebecca Landa, executive director of the Center for Autism Services, Science and Innovation (CASSI) and study lead author, says this model empowers families by helping them to learn strategies to increase their infant’s engagement and communication.
“We know early development sets the stage for lifelong outcomes,” said Dr. Landa. “This study shows we don’t have to wait for a diagnosis to act. Parents can make meaningful progress with their babies through an effective set of strategies.”
Key findings from the study include:
Caregivers who received coaching in use of child engagement strategies were more effective during interactions with their babies than those who received general education alone.
Infants in the coaching group showed greater gains in face-to-face social engagement and nonverbal learning.
Joint attention, such as looking between a toy and a person, nearly doubled in the intervention group.
Caregiver use of targeted strategies increased by 20% after the trial.
Improvements lasted at least eight weeks post-intervention.
Social communication delays are early indicators of disorders such as autism, but interventions often don’t begin until age 2 or 3 years. This study presents a strong case for starting support in the first year of life when the brain is most adaptable.
“This research shows that starting intervention before children are expected to talk could have a major impact on communication development,” said Dr. Landa. “Instead of waiting and watching, we can start supporting families when concerns arise and potentially prevent more significant delays from taking hold.”

CHAMPAIGN, Ill. — When picturing a “typical” alcoholic, people tend to imagine a person drinking at home alone. But that focus overlooks the social origins of many serious alcohol problems, say the authors of a new review paper in the journal Current Directions in Psychological Science.
“Evidence for the centrality of social motives in problem drinking surround us,” write the authors, Catharine Fairbairn, a professor of psychology at the University of Illinois Urbana-Champaign, and Dahyeon Kang, of the University of Washington. “While solitary drinking might serve as a useful early indicator of alcohol use disorder risk … ...

Researchers at the Indian Institute of Technology (IIT) Jodhpur have developed a new low-cost mobile tool to detect arsenic contamination in water sources, addressing a critical threat to human health and the environment.
Published in IOP Publishing’s academic journal Nanotechnology the new tool offers a low-cost, onsite solution for monitoring water quality, especially useful in low-income regions where access to safe drinking water is a major challenge. The sensor is the first to provide on-site, accurate and repeatable results without the need for complex lab equipment ...

Birmingham scientists have identified essential genetic code for a method called plasmid curing, which aims to ‘displace’ antibiotic resistance genes from bacteria.
Plasmids, which are small, circular strands of DNA, play a crucial role in allowing bacteria to share beneficial genes rapidly in a changing environment, most concerningly when they carry genes conferring resistance to antibiotics.
Professor Chris Thomas from Birmingham’s School of Biosciences has investigated plasmid curing ...

“Hic sunt leones,” remarks Stefano Liberati, one of the authors of the paper and director of IFPU. The phrase refers to the hypothetical singularity predicted at the center of standard black holes — those described by solutions to Einstein’s field equations. To understand what this means, a brief historical recap is helpful.
In 1915, Einstein published his seminal work on general relativity. Just a year later, German physicist Karl Schwarzschild found an exact solution to those equations, which implied the existence of extreme objects now known as black holes. These are objects with mass so concentrated that nothing — not even light — ...

Growing communities and extensive agriculture throughout the Western United States rely on meltwater that spills out of snow-capped mountains every spring. The models for predicting the amount of this streamflow available each year have long assumed that a small fraction of snowmelt each year enters shallow soil, with the remainder rapidly exiting in rivers and creeks.
New research from University of Utah hydrologists, however, suggests that streamflow generation is much more complicated. Most spring runoff heading to reservoirs is actually several years old, indicating ...
