can listen attentively during library story hour and participate in the craft activity that follows it, but his 3-year-old sister, Anna, is more interested in walking around and exploring various sections of the library.
What will be an ideal response?
Answer: Growth of the frontal lobe allows Jamil to plan and organize, skills that will help him make an art project. The reticular formation is experiencing rapid myelination, which leads to an increase in attention span. This explains why Jamil can focus on the story, whereas Anna moves from one stimulus to another.
