Just tested it. Mobs cannot spawn on half-slabs ever. I made two buildings. One with full blocks, and one with slabs on the upper half of standard blocks. They had no light and were the same dimensions (8 x 8 x 3). I moved away for about one minute. When I went back, the room with standard blocks was full of mobs, and the one with slabs was completely empty. Hope this helped.
Yeah I added the new top-half slabs to the interior of my cathedral because I didnt want to have torches in the center,
Did a few tests beforehand and found that mobs will not spawn as long as you dont combine them to make a whole block
It was a pain covering such a large area, digging out room below and laying backing down up above, but it was well worth it in the end

What? You tested it? What the hell is wrong with you? Don't you know you're supposed to post something you think you heard once in a youtube video from version 1.0, and then have a glorious flame war over it?
Sheesh. You kids don't understand the internet at all.
Mobs won't spawn on bottom half-slabs, but that's not the issue here. The issue is "high" half-slabs, also known as "top-half" or "upside-down" half-slabs. I don't know if this was true or not when this thread was originally posted, more than a year ago at this point, but mobs can spawn on these "top" or "upside-down" half-slabs as of now in 1.6.2, and at least as far back as 1.4.2 in last October. Example: the shifting-floor witch farm that many of us have built, designed by Pommes Peter.
Can mobs spawn on half slabs if they are on the top half, with air underneath?
I know half slabs stop spawning if they are on the lower half,but double slabs still let things spawn,right?
Basically, do standard slabs stop spawning because of the half-height or because they are not a full block or what?
Thank you in advance for any help!

What do you mean?
If you have a 2 block space beneath it mobs will spawn, also if you have a 1X2 Spiders will,
just put some torches under
Ohh okay, thanks dude!
