Hi All,

I'm new to e-prime and am currently programming the first study for my PhD. I have managed to get everything working (eventually!) and have one final issue I wonder if anyone can help me with.

In the task, two letters on the keyboard are assigned as 'correct' or 'incorrect' responses (z and m). Is there any way to set it so that responses are captured, whether caps lock is on or not? I ran a few pilot trials and in a couple, participants accidentally hit the caps lock button at some point, without realising, and therefore all of their responses from that point were not recorded (i.e. data output said they had not answered).

I tried adding two 'correct response' columns (i.e. both Z and z) but this seemed to be make it so that a correct response has to include both buttons (Zz).

Any help would be gratefully received!

Thanks,
Lizzie

on the slide's properties, on the duration/input tab, set the 'duration' to infinite' and set 'allowable' to zZmM and the end action to Terminate

Lizzie,

I can confirm that JACanterbury's advice works. It seems that the
ACC scoring mechanism is case-insenstive, so for Correct an entry of
either "z" or "Z" will match a response of either "z" or "Z" (I don't
know that this is documented anywhere). I tested this with EP1.2
(which I much prefer for exploratory exercises), I assume the same
holds for EP2.

Of course, there is always the low-tech solution documented at
http://groups.google.com/group/e-prime/browse_thread/thread/6ff76d4d7b9575f8
three years ago: Just yank out the offending key, and if necessary,
back that up with a healthy dose of epoxy. No one needs a Caps Lock
key anyway, and spare/replacement keyboards are cheap if you ever do
need the Caps Lock.

Thank-you both for your help, that's brilliant.

Happy Christmas!
