According to the APA Publication Manual (Section 8.03 Page numbers and running heads)

...Pages occasionally are separated during the editorial process, so identify each manuscript page with the running head along with the page number...  Use the automatic functions of your word-processing program to generate headers and page numbers for your file.  (Do not type these manuscript page headers repeatedly fin your word-processing file).

The running head is an abbreviated form of the title of the paper, not to exceed 50 characters, counting apaces and puctuation, in all caps, and flush left in the same line as the page number.
