While you could access the entire data, for this particular use case for simplicity it would be easier to get data from the last trial (which is the multi-select) and iterate through that data scoring the answers. Replicating the code and experiment you had above, I could correctly score the experiments by changing the debrief block as shown below. When you implement this in your experiment you should adjust the correct answers to include the correct answers in your case. I would be happy to send my entire HTML experiment file if this isn't working for you.
`
var debrief_block = {
type: jsPsychHtmlKeyboardResponse,
stimulus: function() {
var answersHTML = jsPsych.data.getLastTrialData().values()[0]['response']['Q0'];
const correctAnswers = ["آهن"];
var answers = [];
const total = 32;
var correct = total - correctAnswers.length;
// Iterate through each element in the input array
for (const answer of answersHTML) {
// Use regex to extract (number) ArabicCharacter pattern
var match = answer.match(/\((\d+)\)\s*(\S+)/)[2];
match = match.replace("</p>", ""); // removes final header
answers.push(match); // match[2] contains the answer character
}
// scores correct and incorrect items
for (const answer of answers) {
if (correctAnswers.includes(answer)) correct++; // scores correct
else correct --; // scores incorrect
}
return `<p>You responded correctly on ${100
* (correct/total)}% of the trials.</p>`;
},
choices: "NO_KEYS",
trial_duration: 4000
};`

Dear all, I want to both give feedback to respondents and save the data for the number of correct responses when the participant chooses the correct response from a multi-select survey, but I do not know how. Can anybody help? Thanks in advance. `<!DOCTYPE html>
