There are many things we take for granted, but when something goes wrong we see how important they were all along. The mighty cerebellum is essential for many aspects of 'automatic' learning - playing the piano or typing fast, or returning a serve on the tennis court faster than you can think to 'swing'.
The "little voice in your head" under the cerebellum's command. Many of us need that "little voice" to keep information in mind when we're hearing too much at once...as we repeat it back to ourselves it gets embedded more deeply into our memory. Sometimes improving a child's speech articulation can also improve what she remembers because "the little voice" in her head becomes more automatic, and she can use as a back-up memory system.
Many children with individual wiring difficulties or symptoms of 'sensory processing' problems may have cerebellar problems that seem mild, but they may be still bad enough to make it difficult to balance on a bike, write by hand, or carry a tray across a crowded lunchroom. These children may try to compensate cognitively (it's not automatic), but they are often memory overloaded and they become exhausted over the course of the day.
