I have an experiment in which a cue word is presented and participants write a short answer response. I want to record repsonse time from the first keystroke of psrticipants' responses. I have used the parameter k1 as shown in the manual, I also have a duration parameter of d60 for the item. However, I'm not sure what the data represents. On a test tun I waited around 10 seconds before responding, the reaction time data is -7371144, not sure what this means. I know reaction time is milliseconds.
