A child's background and home life can impact their cognitive and emotional well-being. Children learn from lessons, but also from the example and observation of others. Therefore, what they see in their parents, regarding actions and words, could be what they will eventually do and say in their own lives. Children with stable homes and lasting relationships are more likely to have better cognitive and social-emotional development than those who move from house to house or live in an unstable home environment. Most of the time, children in foster care are removed from unstable homes, but they cannot stay in a foster home for their entire childhood. Young children in foster care are very likely to lag behind in their cognitive development and social-emotional functioning compared to children living in a stable home environment. The article Cognitive Development and Social and Emotional Functioning in Young Children in Foster Care: A 2-3 Year Follow-up Study is about a study conducted to determine whether young children in foster care have cognitive development and slower social and emotional functioning than their same-age peers living in their biological parents' home. The researchers' hypothesis was that if children were removed from their biological homes and placed in foster care at a young age, they would fall behind their peers in cognitive development and social-emotional functioning. . Volunteer participants were 36 boys and 24 girls from foster care aged 22 to 25 months, 21 boys and 21 girls from control children aged 22 to 24 months. Four foster families (3 girls and one boy) and two control families (two boys) abandoned...... middle of article...... lmas, AN, Degnan, KA, Nelson, CA , & Zeanah, CH (2011).
