Ambient occlusion options & raytraced shadows not showing?

So I am following thistutorial, and am finding that some of the options are not available.

Both thisand this, are currently not showing, even though they should be. Image attached.

I’m using cycles render and the latest version of blender (2.72), so just wondering if these have anything to do with it.

Thanks in advance!



Tutorial is for Blender Render, the Internal renderer - you are using Cycles, so some stuff might not look the same as far as layout
