audio feedback for mouse click

[Becky Clements]

Hi Paul,

The experiment is a bit convoluted due to there being many contingency
elements during the practice phase of each of the tasks. I am working
on tidying it up but as a novice getting it to work is my current
priority as I learn more I hope I will be able to streamline things.
One thing I forgot to mention in my initial post which is probably
quite important is that each of the slides has a unique audio file
that is either instructions or feedback to the participant it is in
addition to these audio files, which must be there, that I need there
to be a beep when participants touch the screen. I was wondering if
you knew anyway of having in the user script, which would cover all of
the task with in the experiment I am designing, code to have a 'beep'
when participants make a mouse response. Thanks for helping.

Cheers,

Becky
