Registering response times to audio stimulus 'on top of' video file (case 34358)

[Gert Vercauteren]

Hi Jason,

I just found a way to insert the sound files in the existing video clip. So all I would need is a way to register mouseclicks or key strokes in response to those sounds. It would require some more work afterwards since I would have to calculate the difference between the onset of the sound and the moment of the response time (I guess), but if that is easier to realize in the .csv-file, I would be happy to use that option too ;-)

Kind regards,

Gert

Gert,

I'm glad to hear that you got the sound clips to work. To get a keypress for each of these soundclips, you could insert a blank stim cell (by putting just ~ in the stim cell) next to each of the soundclips and then use a fixed response window in conjuciton with the MinMax field of your styles.drt file (see here in the DirectRT manual for more information: http://empirisoft.com/directrt/help/..._rt_limits.htm)
