Detecting voice onset via a Serial Response (SR) box
In a picture naming task, I am measuring the the reaction time it takes between the onset of the picture and the onset of the experimental subject's voice. This works fine by simply pluging a microphone into the computer and using Sebastiaan's Voice_Key script in forum.cogsci.nl/index.php?p=/discussion/1772/
But I need to implement this in a 5-button SR Box (by Psychology Software Tools, Model 200A). The microphone is connected to the SR box. The SR box is detected by Open Sesame but I am having trouble in making OS recognise the microphone. In the SR box widget, I have tried with 'allowed responses = 6', but to no avail ('6' is the 'button' number used in E-Prime for the microphone).
Any tips on how to get OS recognise the microphone as a voice key in the SR box?
