The answer entirely depends on how many items there are for each type of trial.
/ trials = [1=instructions; 2-85=noreplace(ldtcategory, ldtneutral, ldtnonword)]
You are running a total of 84 trials here, and you have instructed the script to run ldtcategory, ldtneutral, and ldtnonword in *equal* proportions: There will be 28 ldtcategory trials, 28 ldtneutral trials, and 28 ldtnonword trials.
If, for example, you have twice as many ldtnonword items (42) as ldtcategory and ldtneutral items (21 each), that needs to be reflected in the proportions you enter:
/ trials = [1=instructions; 2-85=noreplace(ldtcategory, ldtneutral, ldtnonword, ldtnonword)]
will result in 21 ldtcategory trials, 21 ldtneutral trials, and twice as many -- 42 -- ldtnonword trials, a 1:1:2 ratio.
You will find this covered in the documentation for the <block> element's /trials attribute.
