At the Child Emotion Center, researchers explore early biological and environmental risk and protective factors for later mental and physical health of children. Under the direction of the center's founder Professor Kathryn Lemery-Chalfant, graduate and undergraduate students use twin studies to understand how genes and environments work together to influence development. Our methods include measures from multiple levels of analysis, such as genetic, physiological, and behavioral— in order to better understand mechanisms of development and brain-behavior relationships. The overarching goal of the Child Emotion Center is to identify pathways to resilience, or the ability to bounce back from stress and adversity and thrive in life.
CURRENT RESEARCH PROJECTS
Arizona Twin Project
The Arizona Twin Project is a longitudinal research study focused on understanding the influence of genetic and environmental factors on physical health, emotional development and the development of resilience in a sample of twins. Further, our geographical location makes us especially interested in examining these factors among Hispanic families. Having an ethnically diverse sample allows us to consider the interplay between culture and genetics.
Within the Arizona Twin Project, Dr. Kathryn Lemery-Chalfant, Dr. Leah Doane, and Dr. Mary Davis, along with many collaborators, are conducting two overarching studies. One focuses on the genetic and environmental influences on sleep and other biological factors, while the second focuses on physical health and the intergenerational transmission of pain. Utilizing a twin sample allows researchers to disentangle the genetic and environmental contributions on a particular trait. Further, having a highly diverse sample affords us the opportunity to consider the impact of acculturation, as well as the interplay between culture and genetics.
Undergraduate research assistants are needed for the two projects by assisting with participant recruitment, interviewing families with twins, data entry, coding, and becoming exposed to data analysis. This experience will be extremely beneficial for students who plan to apply to graduate school.
Wisconsin Twin Project
The goal of the Wisconsin Twin Project is to uncover characteristics of children and their environment that influence the development of childhood disorders. The disorders we focus on include internalizing disorders such as depression, generalized anxiety, and separation anxiety, and externalizing disorders such as oppositional defiant disorder, conduct disorder, and attention deficit hyperactivity disorder (ADHD). By understanding the development of childhood disorders we hope to reveal ways to prevent these problems and help children develop in healthy ways. The longitudinal study is comprised of young twins born in the state of Wisconsin, and includes numerous environmental, physiological, and biological measures.
Early Steps Multisite Study
Early Steps sample was screened and recruited from Women, Infants, and Children’s nutritional supplement centers when children were 2 years old (N= 731 ethnically-diverse families) and families were selected as at risk on multiple domains. The families were randomly assigned to the Family Check-Up (FCU) preventative intervention, or a control group, and intensively assessed in the homes at ages 3, 4, 5, 7, 8, 9, 10, 14, and 16 (ongoing). The Principal Investigators of the study are Professors Thomas Dishion, Daniel Shaw, and Melvin Wilson. Professor Lemery-Chalfant joined the team in 2014 to genotype the participants and study how genes and environments work together to influence risk and resilience for psychopathology and drug use in adolescence.
