Hi everyone,
I am running a learning task in Inquisit 4
where each Trial is followed by a correctmessage or a errormessage
respectively. These messages are a
stimulus-pool consisting of 6 images each, which are drawn “noreplace”.
However, if I look at the data files, the
critical information which stimulus-picture was acutally shown as
correct-/errormessage is missing. A frame on our monitors lasts 16.6ms and so
17ms should be no problem for Inquisit
to record, as the pictures are only around 100kB in size. Paradoxically,
in another condition where the exposure duration is 32ms the corresponding
information is included in the result-file.
Is there any way to fix this? The missing
information is critical to my research and out of methodical considerations I
cannot increase exposure duration in the 17ms-condition.
Thanks and best regards,
Martin

The pictures are coded as follows:
<picture anger>
/ items = angerfaces
/ select = noreplace
/ size = (100%, 100%)
</picture>
<item angerfaces>
/1 = "vp0204s25maxend.jpg"
/2 = "vp0506s25maxend.jpg"
/3 = "vp0901s25maxend.jpg"
/4 = "vp1002s25maxend.jpg"
/5 = "vp1105s25maxend.jpg"
/6 = "vp1204s25maxend.jpg"
</item>

A normal trial looks like that:
<trial cdot1arew>
/ stimulustimes = [0=mask; 0=circle1, circle2,
circle3, circle4; 283=cdot1a]
/ inputdevice = xid4
/ correctresponse = (240)
/ validresponse = (240, 112, 208, 16)
/ correctmessage = true(surprise, 17)
/ errormessage = true(anger, 17)
</trial>
