Cumulative RT for Two Events

[Jordan Schoenherr]

Hi All,

As my subject indicates, I'm interested in obtaining the RT for two
successive events individually and cumulatively. The latter will be
used for feedback but have accuracy ONLY for the first event. Now,
from what I can tell, the experiment 'NestingXRT' provides an example
of how this can be accomplished.

In the second event, 'time audit only' is selected in the duration/
input window data logging and 'cumulative' is selected in the data
audit window. From what I can tell, this would seem to mean that this
event retains information from the previous two ('stimulus 1' and
'stimulus 2'), however, I'm more concerned about where the
accumulation process starts and how this is specified.

In short,

1) I want to record each event individually;
2) I want to have a way to obtain the cumulative RT for events 1 and 2
(but not fixation or anything else that precedes the stims);
3) Present RT feedback based on cumulative RT (but accuracy only for
the first event).

Any help would be of great assistance!

Cheers,

Jordan
