Everyone seems to have overlooked one interesting aspect of "accomodation"
and "adaptation" in the rush to define them.  That is they are in essence
habituation-like processes.  They represent a common dynamic behavioral
process that is recurrent on many levels of organization in organisms from
desensitization in receptors to habituation of orienting responses.  Dr. Arnold
Mandell has written an extensive review of the subject.
