This appears like a vestibular system check, I don't see the connection with cognitive processes.
I'm no expert, but I'm told by several medical practitioners that a decline in the vestibular functions, as demonstrated by declining ability in performing these "tests", is a fairly reliable marker for the onset of neurological problems.
