Hi all,
I'm trying to program a dual task paradigm...
1. Firstly, i have a auditory task - a word list that is being presented via SoundOut object.
Responses for this portion of the study will be done via the SRBox VoiceKey. A word will be presented randomly from the word list. Response onset will be logged via the VoiceKey, and an ISI of 2500msec separates the subsequent word presentation. If the subject does not respond within the 2500msec, the next word will be presented.
2. Secondly, i have a visual task that will be presenting numbers randomly to subjects. The presentation of these numbers are separated by a mask..
e.g. 4 "Mask" 7 "Mask" 9 "Mask".
The numbers will be up for 250msec, and the mask for 900msec
Response to this task will be logged with subjects pressing the Spacebar. It doesn't matter which point the subjects respond i.e. Number or Mask - so long as we are logging their responses.
The auditory task will keep going till the end of the entire study - Until the "Goodbye and Thank You" screen.
My problem is that i can't seem to have E-prime simultaneously. If i use a Slide object, the presentation of the sound or the visual stimuli is dependent on the duration of the Slide Object.
Furthermore, i would like to have both responses logged. Voice Key and Spacebar.
Your help would be much appreciated!
Mark

I don't know if this addresses what you mean, but it might help to give it a try:
On the main Slide properties, set End Action to none.
On the sound/video SubObject properties, set End Action to Terminate/Jump.
The duration of the Slide will now be equivalent to the duration of the sound/video file.
