Typical Development | Overview
Healthy Baby Study
The purpose of this study is to reduce the prevalence of lifelong health impairments that may be caused by stressful experiences in the early years of life. To learn about this we look at the range of experiences that babies have when they are very young, within their first years of life, and see how those experiences affect the way their brain and body develops.
Eligibility for Participation
- families who have a new baby that is a patient at Children’s Hospital Primary Care Center
- families whose newborn was delivered at 32 to 36 6/7 weeks gestation and admitted to the NICU following delivery
- families whose newborn did not have any major complications during NICU admissions

This study involves five visits to our lab, when babies are 2 months, 6 months, 9 months, 12 months, and 24 months old. All of the visits are timed so they coincide with your baby’s primary care visit to help make it very convenient for you to come in. During the visits we ask you to fill out a few questionnaires and we will show your baby some videos while we record their eye movements. We’ll also use a special, non-invasive cap that lets us see their brain activity while they watch the videos. If it’s ok with you we will also collect small saliva and urine samples from your baby and a blood sample from you at each visit. We offer $50 to you per session, so up to $250 in total, as a thank you for participating, as well as a free toy for your baby. We can also provide free parking or transportation and free childcare for siblings.
It is natural for every family to have a huge range of life experiences (both stressful and non-stressful). For some babies, early stressful experiences have been found to increase risk for health problems later in life. In the current study we aim to understand the range of experiences that babies have, and to determine how different babies respond to those experiences in different ways. To do this we will collect some information from questionnaires, measure a baby’s eye-movements, and record their brain response while they sit on their mom’s lap and watch some fun videos. We will also look at markers in urine and saliva samples from babies and blood samples from moms to see how their bodies respond to the experiences they have had at different points in time.
By using varied methods and following the same babies over their first years, we aim to create a comprehensive picture of risk and resilience during the earliest stages of development. By learning more about how babies respond to the experiences they encounter, we aim to better understand the effects of stress and improve our understanding of which babies are most at risk for health problems later in life. By improving techniques for earlier identification, we aim to create interventions that are best suited to help individual children and their families have the best possible outcomes.
Emotion Processing in Infancy and Early Childhood
The purpose of this study is to investigate the development of emotion processing. Specifically, we are interested in how emotion processing changes from infancy to childhood and how it may be related to other cognitive domains, temperament, physiology, and mental health in children.
Eligibility for Participation
We are no longer recruiting participants for this study. The study team has finished infant and three-year follow-up data collection. We are running five and seven-year follow-ups with families who enrolled at infancy. This study involves one visit to the lab at each time point (when children turn 3, 5, and 7 years). Sessions typically last anywhere from one-and-a-half to three hours. While we contact families at each time point, the follow up visits to the lab are completely optional. Additionally, if families have left the Boston area, there are options for remote participation.

The ability to read emotions in facial expressions is a critical skill that helps us to navigate our social world. In the current study, we aim to understand how this ability emerges and evolves in infancy and throughout childhood. To do this, we measure the brain’s response to a range of emotional faces using electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS). We utilize a variety of behavioral, cognitive, genetic, and clinical measures to help us create a comprehensive picture that charts the developmental course of emotion processing throughout infancy and childhood. We also administer a short temperament assessment, a battery of tests to measure ability in different cognitive domains, and an assessment of physiological responses.
