Response times values 0-1
I've created a Go/NoGo task using the version 3.3.1 of open sesame for Mac OS. In this test, the subject is instructed to provide a response to each visual stimulus appearing in the screen (several geometric shapes) except for one (a circle) pressing the spacebar. Since subjects have to be as accurate and quick as possible, response times measurement is crucial. Yet, the last versions of my script fail to measure the response times! Namely, the value is always 0 or 1. Strangely, the previous version of my script did measure RTs, but I did not change anything in the items concerning keyboard responses recording. So, how can I solve this problem?
Here is my script, if anyone would like to have a look.
