It is, in fact, not a 'normal' behaviour for this age, apart from how common it is for kids in our society to be tremendously stressed, and to have a great deal of difficulty getting enough positive attention.
Since positive attention alleviates both the unmeet need for attention and eases stress, the very last thing that will 'work' is ignoring her. Anything punative will just add to her stress.
She is indicating, through her behaviour, that she is working with a deficit in attention, so the trick for you is to pay more attention to her long before she starts to do it, and to not respond at all when she does. The behaviour will fade as it ceases to be how she has to behave to get attention when she's stressed.
