Dear List

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?

Any ideas?

Thanks
