Hi,
I'm trying to program a task where a person has to continuously rate their heartrate speed as they are watching a video.
This means that there is no defined # of responses (a person can give unlimited responses). This means that there has to be a scale that appears underneath the video and the responses don't interrupt the playing of the video.
Is this possible using Inquisit?
Thanks!

Yes, this should be possible.
Play back the video via a <block>'s /bgstim. Set the <block>'s /timeout to the length of the video. Then, simply run a rating trial in an infinite loop. In a nutshell:
<block myblock>
/ bgstim = (myvideo)
/ timeout = 30000
/ trials = [1=ratingtrial]
</block>
<video myvideo>
/ items = ("example.mpg")
/ size = (50%, 50%)
</video>
<likert ratingtrial>
/ anchors = [1="slow"; 5="fast"]
/ position = (50%, 90%)
/ numpoints = 5
/ anchorwidth = 5%
/ branch = [likert.ratingtrial]
</likert>
