Cognitive flexibility has been measured as a unique characteristic in adult brains. However, scientists have less tools to assess cognitive flexibility during early infancy. A recent study has shown that whole-brain neural flexibility significantly increased with age, and they have demonstrated that more flexible brain function emerged in fifty-two typically developing children during the first 2 years of life.
