 Author Message justcheck1 Respected Member Group: Forum Members Posts: 2, Visits: 18 HiI would like to present a stimuli randomly at one of a series of specific  positions on the screen ("30,20", "50,20", "70,20", "20,50", "40,50","60,50", "80,50", "30,80", "50,80", "70,80")I can randomly select horizontal AND veritcal positions/ items = whites/ size = (20%, 20%)/ resetinterval = 1/ hposition = counter.vertical.selectedvalue/ vposition = counter.horizontal.selectedvalue/ select = whitescounter/ items = (30%, 50%, 70%, 20%, 40%,60%,80%,30%,50%,70%)/ select = noreplace/ selectionrate = always/items =(20%, 20%, 20%, 50%, 50%,50%,50%,80%,80%, 80%)/ select = noreplace/ selectionrate = alwaysHowever, I want to present the stimuli randomly at one of 10 FIXED positions (combinations of vposition and hpositions) on the screen.I tried the following which did not work:/ items = whites/ size = (20%, 20%)/ resetinterval = 1/position = counter.positions.selectedvalue/ select = whitescounter/ items = ("30,20", "50,20", "70,20", "20,50", "40,50","60,50", "80,50", "30,80", "50,80", "70,80")/ select = sequence/ selectionrate = alwaysIt would be really great to get help on this! Thanks in advance Dave Supreme Being Group: Administrators Posts: 9.8K, Visits: 46K All you need to do is have the selection in the vertical counter depend on the selection in the horizontal counter./ items = whites/ size = (20%, 20%)/ resetinterval = 1/ hposition = counter.horizontal.selectedvalue/ vposition = counter.vertical.selectedvalue/ select = whitescounter/ items = (30%, 50%, 70%, 20%, 40%,60%,80%,30%,50%,70%)/ select = noreplace/ selectionrate = always/items =(20%, 20%, 20%, 50%, 50%,50%,50%,80%,80%, 80%)/ select = current(horizontal)/ selectionrate = always justcheck1 Respected Member Group: Forum Members Posts: 2, Visits: 18 Oh, great!
