Sorry, one final question!  I'm trying to use these contrasts on a model
with a binomial error distribution - the only way I can get it to work is
to set the contrasts manually using options(contrasts=c('contr.**sum',
'contr.poly')) as suggested above.  Are the outputted statistics using this
method adjusted using the Kenward-Rogers approximation as in afex, or is it
something different?

Many thanks again!

Sarah
