Giacomo,

* The tapping task in PEBL 2.0 should save as a .csv file based on the
subject code.  If you use subect 100, there should be a 100\ folder in
data\ and in there will be tapping-100.csv.

I have used this task every year in a research methods class, so I'm not
completely sure what you mean by pressing repeatedly or just once.  The
way the task works, I know that the version for 0.14 won't work correctly
with 2.0 PEBL, so that might explain the problem.

Some background for the task:
- the goal is to get a stable measurement of tapping speed.  Participants
should be instructed to tap with the heel of their hand pressed on the
table. In this mode, I have found that I consistently get values around 60
taps/period, +/- 2. My experience is that undergraduate students will
typically be a bit faster than that, but sometimes slower.  With enough
motivation and experimentation, they can sometimes get values 100+, but
not if they keep the heel of their hand pinned on the desk.

The task will continue for 4 or more rounds, until they have produced
consistent responses, with some maximum number of rounds--maybe 8 at most.
 You can select dominant/non-dominant hand tapping options using
parameters, if you only care about one hand.
I hope this helps!
