Subject: Re: Instruction for subjects From: Pierre Divenyi <pdivenyi(at)EBIRE.ORG> Date: Tue, 25 Oct 2005 11:32:39 -0700Fatima, Is there a gap/noise burst in both stimuli of the trial? If yes, I would ask the question "Were the breaks in the glide identical?" If only one of them had the break, tell them "One of the glides have a break -- ignore it and just decide if the two glides were the same or not".
