For within subjects factors, the single df test results are given in a separate table by default. The contrast estimates are also printed (along with the confidence intervals). If you're talking about contrasts on a between subjects factor, you'd need to use LMATRIX rather than CONTRAST, using a separate LMATRIX subcommand for each contrast; then you'll get an F-test for each one. When you use CONTRAST, you get an omnibus test for the set.
