The following is the abstract of a forthcoming article on which BBS
[Behavioral and Brain Sciences -- An international, interdisciplinary
Journal of Open Peer Commentary, published by Cambridge University Press]
invites self-nominations by potential commentators.
(Please note that the editorial office must exercise selectivity among the
nominations received so as to ensure a strong and balanced cross-specialty
spectrum of eligible commentators. The procedure is explained after
the abstract.)

On the Proper Treatment of Connectionism
Paul Smolensky
Institute of Cognitive Science

A set of hypotheses is formulated for a connectionist
approach to cognitive modeling. These hypotheses are
shown to be incompatible with the hypotheses embodied
in traditional cognitive models. The connectionist
models considered are massively parallel numerical com-
putational systems that are a kind of continuous dynam-
ical system. The numerical values in the system
correspond semantically to fine-grained features below
the level of the concepts used to describe the task
domain. The level of analysis is intermediate between
that of symbolic cognitive models and neural models.
The explanations of behavior provided are like those in
traditional physical sciences, unlike the explanations
provided by symbolic models.
Higher-level analyses of these connectionist models
reveal subtle relations to symbolic models. Fundamen-
tally parallel connectionist memory and linguistic
processes are hypothesized to give rise to processes
that are describable at a higher level as sequential
rule application. At the lower level, computation has
the character of massively parallel satisfaction of
numerical constraints; at the higher level this can
lead to competence characterizable by hard rules. Per-
formance will typically deviate from competence since
behavior is achieved not by interpreting hard rules but
by satisfying soft constraints. The result is a picture
in which traditional and connectionist theoretical con-
structs collaborate intimately to provide an under-
standing of cognition.

This is an experiment in using the Net to find eligible commentators
for articles in the Behavioral and Brain Sciences (BBS), an
international, interdisciplinary journal of "open peer commentary,"
published by Cambridge University Press, with its editorial office in
Princeton NJ.
The journal publishes important and controversial interdisciplinary
articles in psychology, neuroscience, behavioral biology, cognitive science,
artificial intelligence, linguistics and philosophy. Articles are
rigorously refereed and, if accepted, are circulated to a large number
of potential commentators around the world in the various specialties
on which the article impinges. Their 1000-word commentaries are then
co-published with the target article as well as the author's response
to each. The commentaries consist of analyses, elaborations,
complementary and supplementary data and theory, criticisms and
cross-specialty syntheses.
Commentators are selected by the following means: (1) BBS maintains a
computerized file of over 3000 BBS Associates; the size of this group
is increased annually as authors, referees, commentators and nominees
of current Associates become eligible to become Associates. Many
commentators are selected from this list. (2) The BBS editorial office
does informal as well as formal computerized literature searches on
the topic of the target articles to find additional potential commentators
from across specialties and around the world who are not yet BBS Associates.
(3) The referees recommend potential commentators. (4) The author recommends
potential commentators.
We now propose to add the following source for selecting potential
commentators: The abstract of the target article will be posted in the
relevant newsgroups on the net. Eligible individuals who judge that they
would have a relevant commentary to contribute should contact the editor at
the e-mail address indicated at the bottom of this message, or should
write by normal mail to:

"Eligibility" usually means being an academically trained professional
contributor to one of the disciplines mentioned earlier, or to related
academic disciplines. The letter should indicate the candidate's
general qualifications as well as their basis for wishing to serve as
commentator for the particular target article in question. It is
preferable also to enclose a Curriculum Vitae. (This self-nomination
format may also be used by those who wish to become BBS Associates,
but they must also specify a current Associate who knows their work
and is prepared to nominate them; where no current Associate is known
by the candidate, the editorial office will send the Vita to
approporiate Associates to ask whether they would be prepared to
nominate the candidate.)
BBS has rapidly become a widely read read and highly influential forum in the
biobehavioral and cognitive sciences. A recent recalculation of BBS's
"impact factor" (ratio of citations to number of articles) in the
American Psychologist [41(3) 1986] reports that already in its fifth year of
publication (1982) BBS's impact factor had risen to become the highest of
all psychology journals indexed as well as 3rd highest of all 1300 journals
indexed in the Social Sciences Citation Index and 50th of all 3900 journals
indexed in the Science Citation index, which indexes all the scientific
disciplines.
Potential commentators should send their names, addresses, a description of
their general qualifications and their basis for seeking to comment on
this target article in particular to the address indicated earlier or
to the following e-mail address:
