Hello, everyone!I came across a tricky question when implementing an experiment in Qualtrics and could use your help. I searched in the forums, but I could not find the answer to the question anywhere, so I am assuming it has not been answered yet; in any case, if it has been addressed before, please do not hesitate to send the post my way.I want to run an experiment in which participants go through a set of faces in order to build a lineup. These faces are grouped by similarity relative to one suspect (very high, high, low, very low). These subsets are randomized and saved as embedded data fields. The presentation of stimuli follows a specific order - very high_1, high_1, low_1, very low_1, very high_2, high_2, low_2, very low_2, etc... So, each participant is bound to see one face belonging to each category in this specific order, though the order within each category is specific to the individual (i.e., very high_1 can be the 5th picture in the original array for one individual, but
Hello, Javascript Newbie here!I am programming an experiment where people see stimuli and have to decide if they are the same or different - and for this they press 1 and 2, respectively. Participants see the stimuli for a set of time and then are presented a multiple choice with the two options; I specifically want them to use the keys, instead of just using the mouse. I want the next trial to start whenever one of the two keys is pressed. In the end, I want the database to have their answers recorded - that is what I am struggling with! The field for the answers always comes out empty.Through foruns here and there, I put together the following code. Can you help me out? What should I change so that when I download the data I can see whether participants pressed 1 or 2?Qualtrics.SurveyEngine.addOnload(function(){this.hideNextButton(); //Blocks from advancingthis.hidePreviousButton(); //Blocks from retreatingvar that = this;Event.observe(document, 'keydown', function keydownCallback(e)
