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.
