How to measure latency of too slow responses

Group: Forum Members Posts: 2, Visits: 1	Hi everyone, I'm currently programming my own version of the Flanker task and I'm having a question about how to record the response latency for too slow responses. Right now I'm having the response time out after 500 ms which should then terminate the trail. Responses that are made after these 500 ms are recorded as incorrect with a response latency of 500. Here is the code for one trial that does this: <trial congruentleft> / pretrialpause= rand(800, 1000) / stimulustimes = [0=fixationcross;500=primeleft;1000=targetcongruentleft;1500=blank] /responsetime = 1000 / response = timeout(500) /validresponse = ("1", "0") /correctresponse = ("1") </trial> I'm wondering if it would be possible to keep everything as is in terms of how the trial appears on the screen, but also record the latency of responses that come in after 500ms have passed. Any advice would be greatly appreciated! Thanks! Jennifer Tags inquisit-4
