Time reaction by vocal key on coder

Coding
1

Hey everyone,

I want to registrate the time reaction of the initiation of a vocal key on stimuli response.

Here’s my code with the key response ‘m’: break + registration of time reactions (rts)
The stimulis are separated with a fixation cross

I don’t want to record the response, only the latency between the stimuli presentation and the vocal response and to register it but I don’t find the answer.

Can someone help me please?

Thank you,

Anastassia
