Stimulus during same frames with insertstimulusframes

Group: Forum Members Posts: 2, Visits: 7	Hi, I have a problem with insertstimulusframe - I have different SOA, and one SOA (9 frames) requires the target ("picture.righttarget") to be drawn on the exact same frame (70) the cue ends ("rightsquare_out, rightsquare_in" whereby rightsquare_in is the black interior of a white square ("rightsqaure_out"), like so: Unfortunately, insertstimulusframe seems to draw the target before the squares, which leads to the target not appearing at all when currentsoa = 9. Is there any way to specify the order several things are drawn during one frame with insertstimulusframes? My code is <trial same_late_right> /ontrialbegin = [trial.same_late_right.insertstimulusframe(picture.righttarget, (61 + values.currentsoa))] /stimulusframes = [1 = fixation; 31=centersquare_out, centersquare_in, leftsquare_out, leftsquare_in, rightsquare_out, rightsquare_in; 61 = rightsquare_out_bright, rightsquare_in; 70 = rightsquare_out, rightsquare_in; 91 = centersquare_out_bright, centersquare_in; 100 = centersquare_out, centersquare_in] ... </trial> Tags insertstimulusframes same frame SOA

Actually that is not how insertstimulusframe() is supposed to behave (and it doesn't behave like that for me). The target is (supposed to be) inserted after the stimuli that are already present in the frame (the outer and inner squares). Here's a simplified script for testing purposes <block myblock> / trials = [1-4=example] </block> <trial example> /ontrialbegin = [trial.example.insertstimulusframe(text.target, (61 + values.currentsoa))] / ontrialend = [trial.example.resetstimulusframes(); ] /stimulusframes = [1 = fixation; 70 = square_out, square_in; 91 = blank] / validresponse = (57) </trial> <values> / currentsoa = 9 </values> <text fixation> / items = ("+") </text> <shape square_out> / shape = rectangle / color = orangered / size = (210px, 210px) </shape> <shape square_in> / shape = rectangle / color = black / size = (200px, 200px) </shape> <text target> / items = ("TARGET") / txcolor = yellow </text> <shape blank> / shape = rectangle / color = white / size = (100%, 100%) </shape> and a screenshot of the result. I'm running this under the most recent Inquisit 4 release. Does the target stimulus show up on your system when running the above example script?
