probe detection task

[Naomi Koerner]

Hi E-Prime Users,

I am constructing a probe detection paradigm using E-prime. Basically, I will a present
a pair of words together on the screen for a few milliseconds. When the word pair
disappears, a probe (a dot or other symbol) appears in the location previously occupied
by one of the words and participants are required to press a button as fast as possible
to indicate the location of the probe (top or bottom of screen). It is a simple
attentional  task, very common. I was hoping someone might have a script for a task
similar to this that I could look at to see whether I've constructed mine properly. If
anyone has a script for a probe detection paradigm of any kind that they could send me, 
I would be so appreciative. I've been working on this for some time and no one in our
dept. has used E-prime for this purpose.

Thanks,

Best Wishes,

Naomi Koerner
