Randomly selecting one of four word then displaying it on four questions without selecting a word twice!

@FritzBreithaupt 

Add this Java code in a Text/Graphic question at the begining of your survey.

Qualtrics.SurveyEngine.addOnload(function() {
    var words = ['cat', 'car', 'mountain', 'ocean'];

    function shuffleArray(array) {
        for (var i = array.length - 1; i > 0; i--) {
            var j = Math.floor(Math.random() * (i + 1));
            var temp = array[i];
            array[i] = array[j];
            array[j] = temp;
        }
    }
    shuffleArray(words);

    Qualtrics.SurveyEngine.setEmbeddedData('PastEventWord1', words[0]);
    Qualtrics.SurveyEngine.setEmbeddedData('PastEventWord2', words[1]);
    Qualtrics.SurveyEngine.setEmbeddedData('FutureEventWord1', words[2]);
    Qualtrics.SurveyEngine.setEmbeddedData('FutureEventWord2', words[3]);
});

This will give you 4 embedded data with 4 word and no duplication

Then display the embedded data to you recall/imagine question with pip-text (for example 1- recall a past event with word ${e://Field/PastEventWord1})

Note: Add page brake between the Text/Graphic question with Javascript and the Recall/Imagine question or put them on different block. Let the embedded data space to get set value.
Let me know if this helps
