Group: Administrators Posts: 13K, Visits: 107K	+x Em - Thursday, September 20, 2018 Dear experts, I've tried looking up the answer in other threads, but can't seem to fit the pieces of the puzzle together. I am showing my respondents 6 images, which are randomized horizontally. In a separate question underneath the pictures, respondent need to indicate which 1 picture out of 6 they choose. To be able to know what picture respondents chose, I need to know at what horizontal position each picture was displayed for every respondent. However, I can't seem to store that data. I tried using the <data> command to store "stimulushpos", but it just gives the same percentage for all 6 stimuli. It would be great if you could help me out! <block ChoosePictureLukas> / trials = [1 = ChoosePicLukas] </block> <surveypage ChoosePicLukas> / stimulusframes = [1=Lukasfem50, Lukasfem30, Lukasfem10, Lukasmas10, Lukasmas30, Lukasmas50] / questions = [1 = possiblenumber; 2 = ChoosepicQ1] </surveypage> <picture Lukasfem50> / select = noreplace / items = ("Lukasfem50.png") /size = (60%,30%) / vposition = 40% / hposition = counter.picpos2.selectedvalue </picture> <picture Lukasfem30> / select = noreplace / items = ("Lukasfem30.png") /size = (60%,30%) / vposition = 40% / hposition = counter.picpos2.selectedvalue </picture> (etc) <counter picpos2> / items = (10%,25%,40%,55%,70%,85%) / select = noreplace / selectionrate = always </counter> The best way is to use values to store the horizontal positions and then log those values to the data file. I.e. <block ChoosePictureLukas> / trials = [1 = ChoosePicLukas] </block> <values> / fem50_xpos = 0% / fem30_xpos = 0% / fem10_xpos = 0% / mas50_xpos = 0% / mas30_xpos = 0% / mas10_xpos = 0% </values> <surveypage ChoosePicLukas> / ontrialbegin = [ values.fem50_xpos = counter.picpos2.selectedvalue; values.fem30_xpos = counter.picpos2.selectedvalue; values.fem10_xpos = counter.picpos2.selectedvalue; values.mas50_xpos = counter.picpos2.selectedvalue; values.mas30_xpos = counter.picpos2.selectedvalue; values.mas10_xpos = counter.picpos2.selectedvalue; ] / stimulusframes = [1=Lukasfem50, Lukasfem30, Lukasfem10, Lukasmas10, Lukasmas30, Lukasmas50] / questions = [1 = possiblenumber; 2 = ChoosepicQ1] </surveypage> <picture Lukasfem50> / select = noreplace / items = ("Lukasfem50.png") /size = (60%,30%) / vposition = 40% / hposition = values.fem50_xpos </picture> <picture Lukasfem30> / select = noreplace / items = ("Lukasfem30.png") /size = (60%,30%) / vposition = 40% / hposition = values.fem30_xpos </picture> (etc) <counter picpos2> / items = (10%,25%,40%,55%,70%,85%) / select = noreplace / selectionrate = always </counter> with <data> / columns = (..., values.fem50_xpos, values.fem30_xpos, values.fem10_xpos, values.mas50_xpos, values.mas30_xpos, values.mas10_xpos, ...) ... </data>
