Children grow and develop rapidly, showing remarkable changes in basic skills such as language during their first years of life. Many children with delays or deficits can be identified rather easily, but the vast majority of children who will eventually show differences are difficult to diagnose early in life. Why? In this talk, Dr. Aslin described the basic techniques that have been developed over the past 50 years to assess the cognitive, social, and language development of young children, especially at ages when they do not yet have the ability to speak using sophisticated language. Exploring the limitations of these techniques, as well as some solutions, he presented findings on the use of brain imaging to detect problems before they manifest themselves in behavior, thereby allowing for even earlier interventions. Armed with new assessment methods, as well as sophisticated data-analysis techniques, there are exciting new prospects for altering the trajectory of development to enable children to achieve their full potential.
Richard Aslin is a Distinguished Research Scientist at Haskins Laboratories in New Haven, CT. Prior to joining Haskins in 2017 he was on the faculty at the University of Rochester for 33 years, where he established the Rochester BabyLab. Dr. Aslin has published widely in several sub-areas of infant development, including perceptual and motor systems, language acquisition, and a rapid form of learning that is based on keeping track of moment-to-moment details in the environment.
In the past decade, Dr. Aslin has focused on extending his studies of infants from using measures of their behavior (such as their eye movements) to gathering measures of brain function with small sensors attached to a baby-friendly cap (such as EEG). His work has shown that the infant brain deploys predictive signals to encode expected events and that patterns of signals from an array of sensors can be used to “decode” which word is heard on a trial-by-trial basis. With these cutting-edge methods he has also shown how infants organize their earliest words based on their sounds and their meanings. These sensitive measures, which can be used with infants before they speak their first words, provide an early window on development, which in turn helps inform further research on children with learning difficulties for early diagnosis.
Dr. Aslin has been the recipient of several major awards, including the APA Distinguished Scientific Contributions Award (2014) and the APS Mentor Award for Lifetime Achievement (2015), and several honors, including election to the American Academy of Arts and Sciences (2006) and the National Academy of Sciences (2013).
