Listing manuscripts in preparation on CV for graduate applications

I am applying to PhD programs in Clinical Psych and was wondering whether or not it would be appropriate to list manuscripts in preparation on my CV when I apply. I am also considering mentioning that I am 'writing the results up for publication' when I describe my research experiences instead of listing the papers under their own header. Curious to hear everyone's thoughts!
