Data Logging Problem

[David Vinson]

Hi Ariene,

My first thought is that your response object is ending before a 
response is made (ie, RT > Duration) but this is a vague guess as I am 
not exactly sure what your problem is.

Can you clarify some details about your experiment:  what is the 
sequence of events and what is the participant meant to do (in very 
basic terms).
And then for the problem responses, what has a value of zero?   For 
example ResponseSlide.RESP = 0?  or ResponseSlide.RT = 0? or 
ResponseSlide.ACC = 0?

all the best,
DavidV

Having run the experiment again a few times, I've found that there is a lack of consistency with regard to which stimulus clip response is not logged, so I don't think the problem can be attributed to the video files themselves (which are in .wmv format - I converted some of the files which were .avi, as I was originally concerned that the different file types may have contributed to the problem, or that the .avi files might've been too large to process smoothly)
