How to save RTs

[valentinavellani]

Hi All,
I have the following trial and I would need to save reactions times.
I suppose I would have a line in on_finish but I am not sure about how it should be

var info_questions_time3 = {
    type: 'survey-likert',
    questions: [
        {prompt: '<span style="font-size:25px; "> Do you think this information is true or false?</span>', labels: scale_accuracy, required: true}
        ],
    scale_width: 1400,
    on_finish: function(data) {
        accuracy_time3 = JSON.parse(jsPsych.data.getLastTrialData().values()[0].responses).Q0+1
        rt_acc = jsPsych.data.getLastTrialData().values()[0].rt
     }} 

Thank you all!

the correct one is actually
JSON.parse(jsPsych.data.getLastTrialData().values()[0].rt)

If you are trying to get the RT from the current trial in its on_finish function, then the data parameter that is passed to on_finish has this information:

var info_questions_time3 = {
    type: 'survey-likert',
    questions: [
        {
		prompt: '<span style="font-size:25px; "> Do you think this information is true or false?</span>', 
		labels: scale_accuracy, 
		required: true
	}
    ],
    scale_width: 1400,
    on_finish: function(data) {
        rt_acc = data.rt
     }
}
