[open] Start Response Interval-checkbox missing in sketchpad
I'm starting to use OpenSesame 0.27.3.
While implementing a visual stimuli with a sketchpad I noticed that the 'Start response Interval'-checkbox is not there anymore? Is there a special reason for this?
I would like to measure a persons responsetime from the start of a stimulus.
Now I (manually) have to correct the response-time afterwards.
This is getting very complex because the stimulus-time can be variable.
Is there an other way to measure responsetime from the start of a stimulus?
