Response time and average response time

Group: Forum Members Posts: 38, Visits: 173	Hello, I need a bit of help on how to find response time and average response time. That is, after presenting the stimuli, I would like to know how long time subject took to response and after all stimuli presentations would like know average response time. A small caveat is that if subject do mistakes, I display a message (using /branch) which consumes about 800ms. To show average response, I would like not to count the time consumed (due to mistake) into my average response time. What script I need to add into my trial (may be in /ontrialend?) Would appreciate any help. Thank you in advance.

As a general matter, the latency property of the trial in which the response occured reflects response time in the current trial. (That you may /branch to some other trial after that does not matter). To calculate average response time, you can add the latency to a <list> /ontrialend and the list's mean property gives you the average of all latencies that were added to it.

Thank you Dave – that’s a good idea, I have implemented it by adding the latency and after end of block I will display the result to the subject. I will post a question along with the implementation on the script that you supported earlier. Have a great day.
