i’m using superlab 2.03 with a serial response box from psychology software tools. we’re measuring latency of response to auditory stimuli. the problem is that for each subject utterance we get multiple voice key responses - some 10 or 20. lowering the mike sensitivity reduces this, but then misses some of the subject responses. is this a problem with the response box? can the software be programmed to ignore voice key responses for a second or so after the first one?
