I am a newbie to jsPsych and am trying to build a language switching experiment using Becky Gilbert's image audio response plugin: https://github.com/becky-gilbert/jsPsych/blob/audio-response/docs/plugins/jspsych-image-audio-response.md I don't know how to get an accurate reaction time for each of my stimuli as the rt function in this plugin defines rt as the time between when the stimulus appears on screen to when the trial ends (rather than rt for each individual stimulus) .

When I run this example (with multiple stimuli), https://github.com/becky-gilbert/jsPsych/blob/audio-response/examples/jspsych-image-audio-response.html. The reaction time is the same for each stimulus even when I say nothing. I really don't know what to do :(
