Our department was fortunate to be able to invite Prof. James Hurford of the University of Edinburgh to speak in the Linguistics department colloquium series. Prof. Hurford is an expert in many areas of Linguistics and in the last 10 years has become one of the foremost linguists working in the areas of the origins and evolution of human language.
Ling 320 benefited doubly from Prof. Hurford's visit. He offered the department an extra talk on the subject of the relation of human and animal cognition, and I jumped at the chance to have it in our class, since the topic was so apropos.
Due to Prof. Hurford's schedule, the lecture was on the first day of class, which was somewhat disadvantageous from an organizational standpoint, but in other ways was a very enlightening and useful way to begin the course. Many of the main questions and themes of the class were touched on and we will refer back to them.
Prof. Hurford graciously offered to let us post both his Powerpoints. The first one in particular will be extremely useful to refer to as we move through the topics in the first part of the course.
Proto-human cognition in non-human animals
ABSTRACT
I will sketchily review a range of evidence from the comparative
psychology literature for animal characteristics that seem to
prefigure aspects of human language in some way. Topics touched upon
will include object permanence, metacognition, episodic memory,
competence with abstract relations, transitive inference, subitizing,
`frame-of-reference' systems, the where/what-dorsal/ventral
separation, and global and local attention.

Jim's colloquium talk in the department
was also about animal cognition, although from a more linguistic
standpoint.
In the talk he proposed a way of
modifying the predicate logic system that many logicians and
philosophers assume is the basic 'language of thought', so that it can
usefully represent the kind of simple predicates that animals seem to
be able to conceptualize.
It makes sense to think that in the course
of human evolution, humans went through a stage in which they shared
a simpler system (simpler than the full-blown semantic
representation of modern humans, that is) with non-human animals.
This proposal is not just arm-chair theorizing, but as Jim showed,
actually conforms to what is known about animal neurological structure
and function.
The colloquium talk corresponds to one section of the paper Hurford
presented at Evolang 6, April 2006, in Rome. That paper is uploaded to
our class's Owlspace site under Resources/Extra Readings. It can also
be accessed as a downloadable .pdf at

April 15 (2006), Session A7, and linking to the title
"Proto-propositions" in James Hurford's talk slot on the schedule.
A parsimonious Begriffsschrift [concept notation] for animals
ABSTRACT
Much of our human thought is not in a fully explicit public language,
with all its paraphernalia of phonological form and grammatical
structure markers. Non-human animals are capable of some degree of
structured thought, but obviously not in a human language. Human
language was built upon, and in its turn modified, pre-existing
structures in animal minds for the representation of the external
world. What are such non-linguistic, but nevertheless semantic,
representations like? This talk works from two ends of the problem:
(1) desiderata for representing the most basic meanings expressible in
human languages; and (2) what we know about human and non-human neural
processes.
A simple 'box' notation is proposed for representing
predicate-argument structure in such a way that it eliminates many of
the separate traditional categories of conventional predicate logic
and linguistic semantics. The most fundamental moves are the
reduction of both individual constants and role markers (e.g. AGENT,
PATIENT) to predicates, and a reduction of all predicates to
one-place. Such moves have precedents in the semantic literature, but
have never been combined in a single approach. The implicit
psychological claims are justified by two main classes of
psychological findings, relating to the distinction between global and
local attention, and internal 'frame-of-reference' systems.
