Dear colleagues,

the Trieste Symposium on Perception and Cognition and the 25th Kanizsa
Lecture will take place at the University of Trieste, November 17, 2017,
starting in the morning.

Traditionally, the Symposium is open to all perspectives and approaches,
has no registration fee, and runs on an informal, relaxed pace.

This year the Kanizsa Lecture will be delivered by prof. Tim Shallice
(University College London) on Friday 17 November, starting at 4.30 pm.

The 25th Kanizsa Lecture

How disorders of supervisory processing relate to the overall organisation
of mind

Tim Shallice
Emeritus Professor
University College London

The lecture will be concerned with what one can learn about the
organisation of supervisory or executive processes from studies of the
cognitive problems of patients with frontal lobe lesions. But what type of
basic process can studies of lesion patients uncover? When cognitive
neuropsychology began in the late 60s and 70s the emphasis was on
individual patients showing strong or classical dissociations between their
performance on different tasks. This was held to provide evidence on the
functions of specific damaged subsystems. However in the 90s it became
clear that some neuropsychological disorders could be explained in terms of
damage to connectionist networks. This led to some theorists, such as
Patterson & Plaut to argue against the utility of studying individual
patients in detail and theoretically to reject the concept of functional
subsystems in favour of connectionist networks composed of sets of ‘hidden
units’. And this approach resonates with the emphasis on networks rather
than individual subsystems coming from resting-state fMRI. I shall take a
half-way house position arguing for the use of a range of
neuropsychological methodologies and theoretically for regions of cortex
having their own specific modifications of basic cortical distributed
processing. I will illustrate this by considering disorders of writing.
The main part of the lecture will be concerned with using this perspective
to understand the disorders arising from damage to different regions of
prefrontal cortex. Before the break, I will briefly discuss disorders of
medial frontal cortex in terms of ‘energisation’ processes and of
frontopolar ones in terms of their role in setting up and realising
intentions. However, the emphasis will be on the contrasting roles of the
left and right lateral prefrontal cortices. Often, a superficial
interpretation of fMRI findings suggests that functions are bilaterally
organised. But lesion data suggests a much greater degree of lateralisation
of function. Moreover, this contrast in function is not adequately captured
by the difference between processing of verbal versus visuo-spatial
material. In addition, I see the left as having specific roles in the
construction of hierarchical representations and in certain type
problem-solving in small well-structured problem-spaces. The right lateral
region will be held to have key roles in active monitoring and, following
Goel, in problem-solving in ill-structured problem-spaces. The left lateral
prefrontal cortex will be held – following Hagoort – to have a
microstructure that facilitates ‘unification’. In addition it will be
speculated that the left lateral prefrontal cortex has a greater degree of
internal inhibition between candidate solutions than the right leading to
winner-takes-all rather than parallel processing.

Besides the KL the Symposium will include workshops and talks on Friday, as
well as a poster session during/after lunch.

If you wish to contribute a presentation, please submit your proposal by
electronic mail to trieste.symposium at gmail.com (specifying whether you
prefer a talk or poster). Each proposal should be submitted as an abstract
(250-400 words). Proposal will be evaluated by a scientific committee.


EXTENDED DEADLINE FOR SUBMISSIONS: SUNDAY 5 NOVEMBER, 2017.

More information about the program will be available on the website:

GUIDELINES FOR THE AUTHORS:

Talk (in English):
15-20 minutes for each presentation (details will be communicated in the
final program).

Posters (in English):
Posters will be grouped thematically and displayed for two hours. A surface
extending 100 cm horizontally and 140 cm vertically will be available for
