hey everybody,
we have two questions:
1. we are trying to create a trial element with the following properties:
we have a text element (instructions) which should be presented for 10 minutes. during the presentation, participants should have the opportunity to press the 't'-key in order to listen to a sound stimulus as often as they like. the text element should be visible the whole time, no matter if they press the key (once/more than once) or not. we want the frequency (number of times participants press the key) to be recorded.
2. for another experiment, we want a block with the following properties:
every time a specific sound stimulus appears, a surverypage should be presented. we want the sound+surverypage (the same every time) to appear three times within 15 minutes, the rest of the time the screen should be all black. the sound+surveypage should appear at three random points of time within the 15 minutes, but there should be at least three minutes in between (at least three minutes black screen) each sound+surveypage.
does anyone have an idea? thank you for helping!
