The multiple looks model
holds that all of the nerve fibers have similar integration times, but that
at some point in the brain, a kind of memory operates. The outputs of the
nerve fibers (the buckets) are stored for 200 or 300 ms, while the listener
scans their contents. If you are trying to detect a sound, you add up the
contents of all the buckets. If you are trying to detect a gap, you look in
the bucket where the gap was supposed to have occurred to so if there is less of a response in it.The buckets in
our analogy are referred to as ÒlooksÓ.
