Does the duck-billed platypus dream?
- by Bernard J. Baars
You can see a dog dreaming: it twitches and whines, and its eyes move in
“rapid eye movement” (REM) sleep. In fact, dreaming in dogs and cats is
quite similar to human dreaming. But a recent study of dream patterns in the
duck-billed platypus, the odd-looking Australian marsupial, reveals an
interesting surprise.

Workshop on
Cognitive Modeling of Agents and Multi-Agent Interactions
August 9, 2003. Acapulco, Mexico
(at IJCAI'2003)
Computational models of cognitive agents that incorporate a wide
range of cognitive functionalities (such as a variety of
memory/representation, various types of learning, and sensory motor
capabilities) have been developed in both AI and cognitive science.
In AI, they appear under the rubric of intelligent agents and
multi-agent systems. In cognitive science, they are often known as
cognitive architectures. These strands of research provide useful
paradigms for addressing some fundamental questions in AI and
Cognitive Science.
Artificial intelligence started out with the goal of designing functioning
intelligent agents. However, faced with the enormous difficulty of
the task, the focus has largely been on modeling specific aspects of
intelligence, often in highly restricted domains. Nevertheless, some
researchers have focused on putting the pieces together with the goal
of designing autonomous agents. More important, there is a growing interest in
multi-agent interactions that addresses issues of coordination and cooperation
among cognitive agents.
On the other side, traditionally, the main focus of research in cognitive
science has been on specific components of cognition (e.g., perception,
memory, learning, language). Recent developments in computational modeling
of cognitive architectures provide new avenues for precisely specifying
complex cognitive processes in tangible ways, thereby addressing foundational
questions in cognitive science. Such developments need to be extended to
multi-agent interactions and there are promising developments in this regard
(see e.g. recent papers in this area in the journal Cognitive Systems Research).
Against this background, this workshop seeks to bring together cognitive
scientists and AI researchers, with a wide range of background and expertise,
to discuss research problems in understanding cognition at the individual
level as well as at the collective level.

CEU Philosophy Department and ELTE cordially invite you to a public lecture by
Harry Frankfurt
Monday, 28 April, 5.30 PM- Popper room (Nador str. 9./room 102)
"Some Mysteries of Love"
Love, in which the will is constrained to a disinterested concern for the good of the beloved, is not necessarily a response to reasons or to value. It is a creator of reasons and of value: things become valuable to us because we love them, and our love means that we have reason to perform the actions that sustaining and promoting their good requires. The ultimate ground of practical normativity and practical reason lies, then, in the contingent necessities of love. These volitional necessities, far from impairing our freedom, are in fact themselves liberating.
Harry Frankfurt is Professor Emeritus at Princeton University, a past president of the American Philosophical Association and a Fellow of the American Academy of Arts and Sciences. He specializes in ethics and the history of philosophy, with particular emphasis on the problem of free will. His publications include the articles "Freedom of the Will and the Concept of a Person,", "Alternate possibilities and moral responsibility" and the books Demons, Dreamers and Madmen: The Defense of Reason in Descartes' Meditations; The Importance of What We Care About and Necessity, Volition and Love.
***************************************************************************************************************************
CEU Philosophy Department and the Humanities Center cordially invite you to a public lecture by
Hilary Putnam
9. May, 5.00 PM - Popper Room
"Ethics Without Metaphysics"
Hilary Putnam, one of America's most distinguished philosophers, surveys an astonishingly wide range of issues and proposes a new, clear-cut approach to philosophical questions -- a renewal of philosophy. He contests the view that only science offers an appropriate model for philosophical inquiry. His discussion of topics from artificial intelligence to natural selection, and of reductive philosophical views derived from these models, identifies the insuperable problems encountered when philosophy ignores the normative or attempts to reduce it to something else.

The emulation theory of representation: motor control, imagery, and perception
Rick Grush
Department of Philosophy
UCSD
La Jolla, CA
ABSTRACT: The 'emulation theory of representation', is developed and
explored as a framework that can revealingly synthesize a wide variety of
representational functions of the brain. The framework is based on
constructs from control theory (forward models) and signal processing
(Kalman filters). The idea is that in addition to simply engaging with the
body and environment, the brain constructs neural circuits that act as
models of the body and environment. During overt sensorimotor engagement,
these models are driven by efference copies, in parallel with the body and
environment, in order to provide expectations of the sensory feedback, and
to enhance and process sensory information. These models can also be run
off-line in order to produce imagery, estimate outcomes of different
actions, and evaluate and develop motor plans. The framework is initially
developed within the context of motor control, where it has been shown that
inner models running in parallel with the body can reduce the effects of
feedback delay problems. The same mechanisms can account for motor imagery
as the off-line driving of the emulator via efference copies. The framework
is extended to account for visual imagery as the off-line driving of an
emulator of the motor-visual loop. I also show how such systems can provide
for amodal spatial imagery. Perception, including visual perception, results
from such models being used to form expectations of, and to interpret,
sensory input. I close by briefly outlining other cognitive functions that
can might also be synthesized within this framework, including reasoning,
theory of mind phenomena, and language.
KEYWORDS: efference copies, emulation theory of representation, forward
models, Kalman filters, motor control, motor imagery, perception, visual
imagery.

*** SUPPLEMENTARY ANNOUNCEMENT ***
(1) Call for Book Nominations for BBS Multiple Book Review
In the past, Behavioral and Brain Sciences (BBS) had only been able
to do 1-2 BBS multiple book treatments per year, because of our
limited annual page quota. BBS's new expanded page quota will make
it possible for us to increase the number of books we treat per
year, so this is an excellent time for BBS Associates and
biobehavioral/cognitive scientists in general to nominate books you
would like to see accorded BBS multiple book review.
(Authors may self-nominate, but books can only be selected on the
basis of multiple nominations.) It would be very helpful if you
indicated in what way a BBS Multiple Book Review of the book(s) you
nominate would be useful to the field (and of course a rich list of
potential reviewers would be the best evidence of its potential
impact!).

THE PHILOSOPHY AND THEORY OF CONSCIOUSNESS - NEW SECTION ON TESTABLE IDEAS
ON CONSCIOUSNESS
A Nagelian Neurology of Consciousness?
- by Chris Nunn
"The aim of this paper is to explore the possibility that Nagel's well-known
account has implications for understanding the neural basis of
consciousness. In a world assumed to be non-dualistic, it is argued that
Nagel's view (i.e. that consciousness is what an organism possesses when
there is something that it is like to be itself) implies that consciousness
is an attribute of some system in the brain that maps patterns of spike
train activity. Various considerations suggest that any such system is
likely to operate on analog principles."
