I would like to add some text between repeats to let them know that they will be repeating the block - how can I do this? The trials in the block also branch to error trials meaning that when I include block feedback, the percentage correct calculated includes these trials. Is there a way to calculate and report percentage correct for a subset of trials? This is one of my block scripts: <block Test1> /trials = [1-4=noreplace(indiv_test_T1, cat_test_T1)] /onblockend = [list.indiv_face_1_T1.reset();list.cat_face_1_T1.reset()] /correcttarget=(percentcorrect, 100, 3) /blockfeedback=(correct) </block> You can set up a <page> element that displays a message that the block will be repeated and display that <page> per the <block>'s /postinstructions As for excluding the the error trials from any calculations, you can do that by using performance metric functions and /branch insteat of /correcttarget. https://www.millisecond.com/support/docs/v4/html/language/expressions/functions.htm percentcorrect(trial.indiv_test_T1, trial.cat_test_T1) Thanks for your help
