I have the stimulus as ( ~My partner IS... ) and the time column as ( rt:57,aud, rec, 10000 ). The task is to complete the statement by vocal response. We are recording the response, using spacebar as stop key to move on, and limiting their response window to 10 seconds.

My question is about the reaction time in the data. Does it time the first sound input (ie the "s" in smart), the spacebar, or something else? We are recording their answers to code for the type of response but we also need to know how long it takes them to respond.
