Re: Instruction for subjects
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".

I am running some pilot behavioral studies of auditory continuity illusion
(aka temporal induction).
The sounds are FM sweeps with gaps or noise-inserted gaps.
For various reasons I am running them as "same/different" trials,
wth the first sound of the trial being a regular FM sweep and the
second one being
the modified FM sweep.
When I ask the subjects, "Is the second sound as continuous as the
first sound?" they become confused.
Even FM sweeps with much-louder noise inserted in the gap are
considered by some subjects to be not very continuous. (contrary to literature)
How do I change my instructions (basically, the confusion is around the
word 'continuous')? Or change the task?
