LUBBOCK – Newsweek Magazine’s article “Reading Your Baby’s Mind” has brought attention
to the dramatic research that is being done on the brain activity of infants and toddlers.
Texas Tech University associate professor Dr. Sybil Hart, author of the book “Preventing
Sibling Rivalry,” was featured in that story.
Hart’s research establishes that children are capable of experiencing this complex
emotion as young as six months of age and that it is particularly well-developed in
infants of highly-involved and caring mothers. This goes against conventional views
of jealousy as a character flaw that emerges only later in development as the brain
establishes more sophisticated cognitive functions and mother-child relationships
are disrupted. Her findings also point to the controversial position that jealousy
has an inborn biologically-based foundation.
Hart studies the importance of exclusivity in relationships by observing interactions
in which a child is ignored in favor of another baby. During testing, she instructs
the mothers to disregard their own child while cooing over a realistic baby doll.
The children, ranging from six-months to one-and-a-half years old, typically display
signs of discomfort that include staring, thrashing, flushing and coughing. Children
typically become angry or sad. These behaviors and emotions indicate that children
are capable of experiencing and communicating feelings of jealousy. Often, however,
these emotions are either missed or misunderstood by parents.
“There isn’t a facial expression with ‘jealousy’ written on it,” she said. “The expressions
can be subtle and it is hard to attribute them to jealousy. If you were looking for
jealousy, what would you be looking for? We look at a child’s response to loss of
exclusivity and contrast it with responses which are displayed in other situations
which involve maternal unresponsiveness.”
Hart is associate dean of research for Texas Tech’s College of Human Sciences and
an associate professor in the Department of Human Development and Family Studies.
