Hi,
You can reference the keys set1
, set2
, set3
and set4
in an array and shuffle it using Ibex’s fisherYates
:
Template("speecherrors.csv", row => newTrial("repetition", defaultText .css("p") .center() .print() , newText("Please repeat the following sets of words as fast as you can when they appear on the screen. Press start to display them.") .css("p") , newButton("Start") .log() .center() .print() .wait() .remove() , newTimer("wait", 1000) .log() .start() .wait() , newMediaRecorder("speech_set1", "audio") .log() .record() , newText( "blank line" ) .hidden() , row.sets = ["set1","set2","set3","set4"], // array of keys fisherYates(row.sets) // shuffle the array , newText("set1", row[row.sets[0]]) // use the first (shuffled) key .log() , newTimer("wait", 3000) .log() .callback(getMediaRecorder("speech_set1").stop()) .start() .wait() , getText("set1") .remove() , newTimer("wait", 1000) .log() .start() .wait() , newMediaRecorder("speech_set2", "audio") .log() .record() , newText("set2", row[row.sets[1]]) // use the second (shuffled) key .log() , newTimer("wait", 3000) .log() .callback(getMediaRecorder("speech_set2").stop()) .start() .wait() , getText("set2") .remove() , newTimer("wait", 1000) .log() .start() .wait() , newMediaRecorder("speech_set3", "audio") .log() .record() , newText("set3", row[row.sets[2]]) // use the third (shuffled) key .log() , newTimer("wait", 3000) .log() .callback(getMediaRecorder("speech_set3").stop()) .start() .wait() , getText("set3") .remove() , newTimer("wait", 1000) .log() .start() .wait() , newMediaRecorder("speech_set4", "audio") .log() .record() , newText("set4", row[row.sets[3]]) // use the fourth (shuffled) key .log() , newTimer("wait", 3000) .log() .callback(getMediaRecorder("speech_set4").stop()) .start() .wait() , getText("set4") .remove() , newTimer("wait", 1000) .log() .start() .wait() , newMediaRecorder("speech_target", "audio") .log() .record() , newText("target", row.target) .log() , newTimer("wait", 3000) .log() .callback(getMediaRecorder("speech_target").stop()) .start() .wait() , getText("target") .remove() ) .log("first", row[row.sets[0]]) // log the first shuffled key .log("second", row[row.sets[1]]) // log the second shuffled key .log("third", row[row.sets[2]]) // log the third shuffled key .log("fourth", row[row.sets[3]]) // log the fourth shuffled key .log("target", row.target) // log the target word too )
