Hello,
I'm using a RSVP paradigm to create a psychological refractory period experiment.
I present a sequence of letters, each presented for 30ms with 70ms of empty screen in between the letters. I need to measure RT for a first target letter and then RT for the second letter with comes at an SOA of 100, 200, 400 or 900ms.
I would like to readkey for the first target letter for 2000ms and readkey for the second target letter for 2500ms.
My problem is that I cannot figure out how to be still reading key for target 1 and at the same time have the following stimuli keep going.
I have read as few similar thread and the lesson "Let a stimulus disappear while keep waiting for response" which talks about this issue, but I still don't know how to do it since I don't only have dead waiting time following my target stimulus.
Any help with this would be much appreciated.
Emma
