Do the data bear this out? There are no entries for notaskproc; it
never launches? Have you tried, during testing, prematurely hitting the
key that moves the slide on to see what happens? In my experience, if
there is an unexpected way to proceed through the experiment, subjects
will find it (& that's probably a good thing, because it leads to
refinement).<br>
<br>
The key that moves the slide on should only be an allowable response in
notaskproc, therefore hitting it prematurely should do nothing. Is this
the case?<br>

I'm running an experiment where I have divided a list into four blocks,
that is, the list consists of 160 trials and after 40 trials it leaves
the list to run another procedure which consists of one slide where
participants are told whether or not to generate random numbers during
the next block (actually one of 3 procedures: 'taskproc' 'notaskproc',
'endproc'). It's all been running fine. But I have found that for some
participants it occasionally skips this step and they therefore end up
doing one big block (consisting of 80 trials). Has anyone experienced
this kind of thing before and do you have any suggestions as to what it
might be? Could it be a hardware problem (e.g. the keyboard)?
<br>
<br>
Any suggestions would be much appreciated as I just can't figure out
why it's doing it. When I run through the experiment myself it's always
fine. It's also not possible that participants are accidentally hitting
the key that moves the slide on as I deliberately chose a key away from
the keys they are using to respond to the trials (and I don't tell them
which key it is).

Thank you,
