Responses missing from output (case 12271)

[sandraob]

Hello,

I am trying to run a DirectRT file (v2008.2.103.1115) where a number appears for 313ms, followed by a mask for 1126ms. Participants must press the spacebar when any number except 3 shows up; for 3 they must withhold a response. I need to record the RT of the response (if any) if it occurs at any point during either the 313ms or the 1126ms, so I set up two separate points that an RT can be taken.

I created two styles (10 and 11 in the attached .drt file) to do this, but when I look at the output file, any stimulus for which a response was withheld is missing from the file, instead of "no response" being logged.

I'm sure I've probably just omitted or misprogrammed something silly, so any help on this matter would be greatly appreciated! I've attached the input file, styles and some of the .bmp images. I'll post the others in a reply as I can only include 5 attachments here.

Many thanks,
Sandra
