    Where is keypress output stored for vocal responses?

    In the help for Direct RT it tells you how (see below) to specifiy valid key codes so the experimenter can code via the keyboard participant vocal responses, and says these keyboard responses are stored with the audio data. Where exactly are they stored? When I check the log file it just shows -1 for a vocal response under the response column.

    Thanks.

    Advanced Hint
    Note that you can specify valid key codes prior to the audio functions to allow a keypress to be stored with the audio data. This is especially useful if an experimenter wants to code responses via the keyboard after each of the subject's vocal responses. An example:
    rt:any,aud,rec,-1500,clear-1
    This example will take an audio RT, clear the stimulus from the screen at the RT, record the response for 1500ms beyond the RT and will allow any keypress to be coded during that time.

    Can you post your input file and a sample log data file? Will be happy to take a look.

    Here you go. The sample log file only contains a trials, but I clicked left or right mouse button for each one, and I don't see the codes for those showing up in the log.

    Thanks!

    The data file you attached looks like the short form data file. Did you happen to also check the log version from the data "log" subfolder?

    Yes, I did, sorry, I posted the wrong file. Here's the log file.

    Try using key press responses instead of mouse click responses and see if that works. I'm not sure if the code allows for mouse input with this particular function.
