Group: Forum Members Posts: 3, Visits: 22	Hi there, I have a block of trials that repeats until the participant reaches 100%. 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>
