Multiple keypress responses?

[bashorkl]

Hi, I'm new to the jsPsych online experiment builder and need some help. How do I record multiple keypress responses per trial (i.e. a double digit response per trial)? Thank you in advance!

Hi @bashorkl,

At the moment none of the built-in plugins allow you to do this. There are a few options:

1. You can use two consecutive -keyboard-response trials to capture the input. If you make the stimulus the same then the participant won't notice that the trial has "switched."
2. I believe that @kurokida's psychophysics plugin allows for this. See here.
3. You could modify a plugin file to allow for multiple keypresses.
4. You could use the survey-text plugin if you don't mind responses being typed into a form element.
