Any kind of scratching noises attract them because it sounds like a mouse. 

Getting low to the ground makes you less threatening and smaller - notice how they run away when you stand up at your full height.

Holding your fingers out makes you less threatening because they can come close and smell you to learn your scent, and by staying at the limit of your reach they're safe from being picked up suddenly.
