trouble with subliminal presentation times

[baruche]

[edited by moderator]
i have just completed running an experiment that involves subliminal priming. when reviewing the log files i found that, for about 30% of the participants, some stimuli were presented for more then 10 times the requested time. i am attaching the log file of one such particpant. as the file shows, most of the time dRT did present the stimuli for the requested time (35ms), but sometimes (unexpectedly) for 200ms and even 400ms. i have no idea if ps were aware of these presentation when the occured as i debrief them only 40min later. do you have other reports of this phenomenon?
