Group: Forum Members Posts: 6, Visits: 43	Hi, I have a series of picture elements with 2 kinds of animations. I want to randomize between these two animations, so that each picture will randomly have either a circle animation or a path animation. I couldn't find a function that could do this, so I tried hard coding it like so: <trial panda> / stimulusframes = [1=noreplace(picture.pandapath, picture.pandacircle), video.panda_audio; 200=next1] / inputdevice = mouse / validresponse = (next1) / beginresponsetime = 2000 / recorddata = false </trial> <picture pandapath> / items = ("distractor23.jpg") / size = (900, 900) / animation = path(2000, 1, 45, 50, 55, 50, 50, 50) </picture> <picture pandacircle> / items = ("distractor23.jpg") / size = (900, 900) / animation = circle(2000, 1, 0, 600, 375, 50) </picture> (This is just an example of one of the pictures, but I have more). But when I do this, the panda_audio won't play during the trial, so there's silence when there should be (the same) audio file playing each time the trial is played, no matter if it's a path or circle animation. Any idea of how I could randomize between these two animations while also playing audio? Thanks!

The problem is that you can't have a selection mode (here: noreplace() for the two picture elements) AND a static stimulus (here: the video) in the same frame specified in /stimulusframes. You can either (1) use the /inserstimulusframe() function instead to achieve the equivalent result <block exampleblock> / trials = [1-10 = panda] </block> <trial panda> / ontrialbegin = [ trial.panda.insertstimulusframe(list.pandaanims.nextvalue, 1); ] / ontrialend = [ trial.panda.resetstimulusframes(); ] / stimulusframes = [1=video.panda_audio; 200=next1] / inputdevice = mouse / validresponse = (next1) / beginresponsetime = 2000 / recorddata = false </trial> <list pandaanims> / items = (picture.pandapath, picture.pandacircle) / selectionmode = random / replace = false / poolsize = 10 </list> OR (2) you can separate things out into two adjacent frames: <trial panda> / stimulusframes = [1=noreplace(picture.pandapath, picture.pandacircle); 2=video.panda_audio; 200=next1] / inputdevice = mouse / validresponse = (next1) / beginresponsetime = 2000 / recorddata = false </trial> Edited 5 Years Ago by Dave
