Subject:      can anyone help me?
Content-type: text/plain; charset=US-ASCII

Hello,

Since there where no responses, I would like to try again if anyone
can help me with this.

I've taken reactions (time) from persons.
they got 200 stimuli (1 after another) and had to respond to each
stimuli as quickly as possible.
195 stimuli are expected, and 5 stimuli (spaced within the 200
stimuli) are unexpected, so the reactiontime of these 5 are usually
longer.

I want to test if the reactiontime of the unexpected stimuli differs from
the reactiontime of the expected stimuli.

What is the best way to deal with this kind of data?

thanks in advance,
anja
