Generating triggers with key press in a text input form


I am preparing an experiment where participants are asked to type words individually (and press ENTER after each word) in a text input form. I would like to send a trigger as participants press the first key for each word. So far, I haven't managed to do this, as my key log/trigger always waits for an input, which is then not taken into account in the form (so you need to type the first letter twice).

Any help is greatly appreciated.




  • Hi,

    THis is not possible within the same text input field. Is it not an option, to use two sequential text input fields? In this case, you can add an inline_script after each form, that includes the trigger sending procedure.
