Depending on who made the diagnosis, it could mean one thing or the
other, but given that most dyslexia is based on a developmental
language weakness (the old idea of perceptual problems may hoold true
for a small subgroup, but even here may be based on a misinterpretation
of putatively visual perceptual errors). Poor "decoding" of auditory
information is at least an aspect of this, and perhaps the core of it.
Paula Tallal, for example, would consider it as the core defect, and
her research suggests it is based on poor temporal resolution of speech
sounds--for example, detecting the difference between the "b" in "bat"
and the "c" in "cat" depends on ability to discriminate between two
different rapidly changing sounds across a duration of about 30-40
milliseconds.
One of my speakers at the NYNG conference May 5 will be describing a
remediation technique based on this research. For full program, see:

Last time I mentioned this in this newsgropup, someone cited a critique
of Tallal's work by Studdert-Kennedy, but did not give specific
reference. Lit search turned up one article by him which controverted
the idea that dyslexia involves a sequencing problem, but Paula
controverted this by other means much earlier; don't know if this was
the intended reference (if you're out there, post exact ref, please).
