Many parents of premature babies fear that their child will have later difficulties in school, but research shows that most babies born prematurely are ready for kindergarten on time and achieve similar academic outcomes to full-term babies.
Adolescent drinking may lead to difficulties adapting to stress as an adult, at least in rats.
Babies exposed to tobacco products in utero, or shortly after birth, have an increased risk of behavior problems.
Researchers in Oslo have used modeling to construct images of how newborn infants see people around them.
New research suggests that young infants can already distinguish between different kinds of touch on the skin.
Infant-directed song may have evolved as a way for adults to signal to infants that their needs are being met.
Toddlers in noisy environments may have more difficulty learning new words.
Regularly reading out loud to children, beginning in infancy, can increase vocabulary and reading skills even before they enter school.
Even brief exposure to a language in infancy affects how the brain is wired for language.
Children with low levels of language stimulation in the first three years of life have a higher risk of childhood depression.
What does toddlers’ use of “a” and “the” tell us about their language development?
Researchers have confirmed that reading to children before they enter kindergarten changes the way the brain processes stories, and may predict later reading success.
Studying a second language, even for a short period of time, improves attention skills.
New brain wave studies show that sounding out words increases activity in parts of the brain wired for reading.
People who stutter have less blood flow to Broca’s area, which controls productive language in the brain.
A new study shows that connections between the brain’s left and right hemispheres strengthen during sleep.
Learn how concussions affect the brain.
This TED talk explains how sugar affects the brain, and why sugar tends to be so addictive for many people.
Preschoolers with better fine and gross motor skills perform better on kindergarten readiness measures.
Activities that require balance, such as climbing trees and balancing on a beam, can improve working memory.
Children with poorer-quality sleep tend to have higher body mass index than children who sleep better.
Age-appropriate bedtimes and regular sleep may be important for children to maintain healthy body weight in adolescence.
Sleep-deprived adolescents are more likely to engage in risky behavior.
Researchers have discovered that many infants begin eating complementary foods too soon. Current recommendations suggest introducing solid foods to infants at 6 months of age.
Attachment and Relationships
Research suggests that both older and younger siblings contribute to the development of empathy in each other.
Research suggests that infants learn prosocial behavior through imitation. When they observe helping behavior, they are more likely to be helpful.
This working paper, released by the National Scientific Council on the Developing Child, summarizes research on early relationships and childn development.
