comparison of vision and auditory system

I find this point interesting because this is also true in the auditory
system. The frequency JND is very small, but the acuity of temporal events
is suprisingly bad. I have always assumed that in the auditory system this
was by design, because of the degrading effects of echos and reverberation,
for example.

If the temporal acuity is quantitatively similar (is it?) in the two system,
then this might be saying something about how the CNS functions.
For example, for the auditory case, it seems likely that the reason for the
poor temporal acuity across frequency is that the information is being
merged after many "layers" or stages of processing. This follows from
the old observation that temporal acuity necessarily decreases for deeper

Does this make sense to anybody, or is this just the sound of soft wind?
