Hi Jeremy,
Thank you for creating and maintaining PCIbex! I’ve found it super useful! I’m wondering whether it’s possible to randomize the order by which multiple audios are played in a single trial. Here’s a link to the experiment. I’m building a word learning experiment where at each training trial, participants will see multiple objects and hear multiples non-sense words, and they will need to learn the word-object mapping. As shown in the code below, the order of the three audios at each trial is fixed, and I wonder if they can be randomized? Thanks!
// Trainings trials Template("training.csv", row => newTrial("training", newTimer("break", 1000) .start() .wait() , newImage("image1", row.image1) .size(200, 200) , newImage("image2", row.image2) .size(200, 200) , newImage("image3", row.image3) .size(200, 200) , newCanvas("side-by-side", 700,200) .add( 0, 0, getImage("image1")) .add(250, 0, getImage("image2")) .add(500, 0, getImage("image3")) .center() .print() , newSelector("selection") .add(getImage("image1"), getImage("image2"), getImage("image3")) .disableClicks() .shuffle() , newAudio("audio1", row.audio1) .play() .wait() , newTimer("break2", 1000) .start() .wait() , newAudio("audio2", row.audio2) .play() .wait() , newTimer("break3", 1000) .start() .wait() , newAudio("audio3", row.audio3) .play() , newTimer("break4", 1000) .start() .wait() , getAudio("audio3") .wait("first") ) .log("group", row.group) .log("item", row.item) .log("condition", row.condition) )Hi,
Yes, you can use plain javascript to randomize the order of the audios. Here’s how I would go about it:
Template("training.csv", row => newTrial("training", audios = [row.audio1,row.audio2,row.audio3].sort(v=>0.5-Math.random()), newTimer("break", 1000) .start() .wait() , newImage("image1", row.image1) .size(200, 200) , newImage("image2", row.image2) .size(200, 200) , newImage("image3", row.image3) .size(200, 200) , newCanvas("side-by-side", 700,200) .add( 0, 0, getImage("image1")) .add(250, 0, getImage("image2")) .add(500, 0, getImage("image3")) .center() .print() , newSelector("selection") .add(getImage("image1"), getImage("image2"), getImage("image3")) .disableClicks() .shuffle() , newAudio("audio1", audios[0]) .play() .wait() , newTimer("break2", 1000) .start() .wait() , newAudio("audio2", audios[1]) .play() .wait() , newTimer("break3", 1000) .start() .wait() , newAudio("audio3", audios[2]) .play() , newTimer("break4", 1000) .start() .wait() , getAudio("audio3") .wait("first") ) .log("group", row.group) .log("item", row.item) .log("condition", row.condition) .log("audio1", audios[0]) .log("audio2", audios[1]) .log("audio3", audios[2]) )Jeremy
