Young Children's Ability to Climb Fences
通过三项实验评估了24至54个月幼儿攀爬常见围栏的能力，发现普通链环围栏即使两岁幼儿也能轻易攀爬，而其他类型围栏对低龄儿童有更好的阻隔效果。
Three studies were performed to evaluate the fence-climbing abilities of children who are in the high-risk age group for drowning in residential pools. Study 1 examined the ability of children in the age range of 24 to 54 months to climb commonly used fences (common chain link, small chain link, picket, iron, and stockade) at a 4-ft (1.22-m) height. Study 2 examined children's abilities to climb fences retrofitted with features that would potentially make them more difficult to climb. Study 3 examined children's abilities to climb 5-ft (1.52-m) fences. Results of the three studies show that the common chain-link fence is easy to climb even by two-year-old toddlers. Other fence types offered more effective barriers, especially for younger children.
