Hi,
I am currently trying to program an experiment that records the verbal response provided by the participants. I used the /inputdevice = voice record one and it does record the response and also stores recordings. However, i am not sure about the latency it provides (in my case all of the trials have same latency). I want the response time (saved as latency if possible) to be time between the stimulus onset (presentation of faces) and the first utterance by the participants. I am a beginner in Inquisit and i am not sure what can be done for this. Could you please help me with this?
