Research

My research is on socio-emotional development in infants, toddlers, and preschool children with an emphasis on the development of, and individual differences in, infant emotional reactivity and the ability to regulate emotion in infancy and early childhood. Specifically, I have been investigating how the infant’s temperament, physiological make-up, and parenting environment, each contribute to the emergence of the self-regulation of the emotions of anger and fear. More recently, I have become interested in the application of temperament and emotion regulation to physical health. I am collaborating with others to examine the impact of temperament and parental soothing strategies on childhood obesity. In addition, we are studying how positive affect can reduce the effects of stress on children’s immune system. Below are descriptions of two studies for which data collection is completed but coding and analysis continue.

Emotional Beginnings Project. As children develop they are increasingly asked to control their emotions and behavior. Waiting for food, walking but not running, and refraining from touching interesting objects, are just a few of the prohibitions that children face. One particular developmental task is the tolerance of frustration. Being asked to stop playing and come inside to do a chore requires the child to inhibit feelings of anger about having to stop an enjoyable activity. This ability to control one's emotions is often referred to as emotion regulation. The development of the ability to regulate one's emotion is believed to be a product of the child's temperament and environmental influences, specifically parental socialization. One of the primary purposes of the Emotional Beginnings Project of the Infant and Child Temperament Laboratory is to investigate how infants and toddlers come to regulate their emotions. To accomplish our goals we conducted a longitudinal study that was funded by the National Institutes for Mental Health. In this study children and their parents were seen several times from when the child was 2 weeks of age to 6 years of age. We used home visits, inoculation visits, and laboratory visits to gather our data. We also collected heart rate data as a marker of regulation. In addition, questionnaires and infant cry diaries were completed by parents. At the inception, 150 families had joined the project.

To date, we have published a number of papers on the Emotional Beginnings Project data that focused on parent regulation of infant crying, the psychophysiology of early social behavior, the impact of excessive crying on emotion regulation, the stability of temperament types, the socialization of emotion, and the relations among behavioral, emotional and cognitive forms of regulation. Most recently, we published a paper that demonstrated that exuberant children who were unable to regulate their disappointment were at greater risk for behavior problems than inhibited and low reactive children. We are continuing to work on papers that based on the rich, complex data of the Emotional Beginnings Project. In addition, doctoral and honors students are continuing to use these data set for their theses.

Family Life Project. The Family Life Project was five-year collaboration between researchers at Penn State University and the University of North Carolina at Chapel Hill, designed to study children and families living in rural poverty. The primary goal of the project was to develop an understanding of the unique ways community, employment, family economic resources, parent-child relationships, and individual differences among children influence development and competencies in children during their first three years of life. Our lab has been involved in Project 1 which is concerned with the characteristics of infants and children growing up in rural poverty. We have been focusing on the child’s temperament and physiology including heart rate and cortisol reactivity. We recently published a study comparing the assessments of parents, our home visitors, and behavioral coders on the infants’ negative and positive reactivity. Students are also actively involved in writing papers and theses from this unique data set.
