I recall reading a paper decades ago in what was then called the
"Bell System Technical Journal" (BSTJ) in which they reported on
human response times for a (member x memorized-word-list)) task.
[BSTJ used to publish a lot of human engineering & perception research
in those days.] The fascinating thing about the results they got
was that the response time was linearly proportional to the length
of the memorized word list, but *not* to the position of the test
word in the list!
