Summation across blocks

[Morgan]

Hello all,

I just posted this to the group:

I'm attempting to program an n-back task in E-Prime and am currently
trying to figure out how to have the task generate a performance
summary to be displayed at the completion of the task, which would
include % of correct responses, % of incorrect responses, reaction for
correct responses, reaction for incorrect responses, and the number of
omitted trials across the entire task (in other words, not after each
trial or each block, but at the end of all of the trials/blocks).
Would any of you know how to do this?

Based on this thread, I was wondering if any of you might have an idea
about this question.

Thanks so much!
