Hi all,

I am having a bit of trouble getting Pavlovia to recognize jsPsych 7.1.2 as the software platform and I can’t seem to pinpoint if my error is stemming from a simple pathway issue, something I am misunderstanding about the jspsych-7-pavlovia-2022.1.1.js plug-in (given the recent migration to jsPsych 7.0), or if there’s something else that I am not seeing.

To try to figure out what the problem may be, I created a simple “welcome” task that should just launch a “Welcome” message. I’ll attach the code below. In case it helps, my Pavlovia directory structure is:

jspsych folder with the relevant plug-ins
the welcome.html file
the welcome.js file

Any suggestions on what I may be misunderstanding about how Pavlovia integrates with jsPsych v7.0 would be especially appreciated. Thanks so much!

Here is the welcome.html file

<!DOCTYPE html>
<html>
  <head>
    <title>Pavlovia Study</title> 

    <script src = "jspsych/jspsych.js" ></script>
    <script src = "jspsych/plugin-html-keyboard-response.js" ></script>
    <link href = "jspsych/jspsych.css" rel= "stylesheet" type= "text/css">
    <script type="text/javascript" src= "jspsych/plugin-pavlovia-2022.1.1.js"></script>
    <script src = "welcome.js"></script>
    <style>
        body {
background-color: black;
       } 
 .jspsych-display-element {
     font-size: 30px;
     line-height: 2em;
 }
</style>
</head>
<body></body>
<script>

//Run timeline
jsPsych.run(timeline);

</script>


</html>

Here is the welcome.js file

    /* initialize jsPsych */
    var jsPsych = initJsPsych({
        on_finish: function () {
          jsPsych.data.displayData();
        }
      });
  

//Create timeline
var timeline = [];


    /* init connection with pavlovia.org */
    var pavlovia_init = {
        type: jsPsychPavlovia,
        command: "init"
    };
    timeline.push(pavlovia_init);


    /* define welcome message trial */
    var welcome = {
        type: jsPsychHtmlKeyboardResponse,
        stimulus: "Welcome to the experiment. Press any key to begin."
      };
      timeline.push(welcome);


  		/* finish connection with pavlovia.org */
          var pavlovia_finish = {
			type: jsPsychPavlovia,
			command: "finish",
			participantId: "JSPSYCH-DEMO"
		};
		timeline.push(pavlovia_finish);
