Adsense Ready Theme – Personalising

I am using Adsense Ready WordPress Theme 01 and it looks great. But how do I know that the adverts are personalised to my own AdSense account? I’m a complete newbie to WP and AdSense so I’m sorry if this is a really basic question but I’ve searched around and can’t seem to find a simple explanation or instructions to do this?
Many thanks for your help.
