Werner conducted a longitudinal study of children on the island of Kauai (the Garden Island) in Hawaii. This study had two objectives: to investigate the long-term effects of prenatal or perinatal stress and to record the effects of early educational adversities on a child's physical, cognitive, and psychosocial development. She used a sample of 698 infants out of 1963 live births to carry out this study. The study included these infants aged one, two, 10, 18, 31 and 32 years old. She asked community members to take a census of women around the garden aged 12 or older to find out the number of pregnant women. women and ask non-pregnant women to send a message when they have become pregnant. She obtained information about the mothers' postpartum period when the children were between one and ten years old from nurses and social workers. Nurses were responsible for observing women during each trimester of pregnancy if any difficulties were encountered, such as physical or emotional stress. Doctors monitored any difficulties encountered during the prenatal phase, labor, delivery and neonatal phase. She brought in pediatricians and psychologists to examine the children's physical, intellectual and social development while documenting whether any of them suffered from disabilities or behavioral problems. She and her colleagues also administered several tests such as aptitude, personality, etc. at primary and secondary levels. Finally, they interviewed the children aged 18, 31 and 32 to find out their outlook on life. In 1955, some children died from exposure to prenatal or perinatal stress between birth and age two. 116 children were diagnosed with physical or mental difficulties at the age of two and 142 children were left middle of paper......what their lives were like. They found that 86% of resilient children appeared to do well as adults and, compared to non-vulnerable children, reported being happier. However, they recorded a large number of health problems such as dizziness, back problems for men and pregnancy and childbirth for women. Additionally, other children in the vulnerable group reported significantly better outcomes compared to their adolescents, for example returning to school, finding employment, etc. The study proves that children can grow up to become competent members of society even if they are born in impoverished environments and stressful situations provided there is a balance between environment, stress and support . it suggests early intervention programs and nurturing environments for children in vulnerable situations to improve child development in the future..
