Уважаемые коллеги!

Настало время для нашего семинара возобновить свою работу после
каникул. Однако в этот раз в начале октября вместо привычного сбора в
начале семестра мы предлагаем всем вместе отправиться на лекции Патрика
Каванаха (Harvard University, USA; Dartmouth College, USA; Université
Paris Descartes, France), посвященные зрительному восприятию, а
также отображению законов зрительного восприятия в изобразительном
искусстве.

Лекции пройдут в ВШЭ, однако по разным адресам. Все лекции состоятся на
английском языке, будет доступен резюмирующий перевод на русский язык.
Последняя лекция (9 октября) состоится в рамках ежегодного семинара
"Великая иллюзия сознания".

Зарегистрироваться на лекции можно по ссылке:

Тем, у кого нет пропуска ВШЭ, при входе необходимо иметь с собой
паспорт.

The artist as a neuroscientist

A piece of art can trigger many emotions and impressions, many of them
just as the artist intended. However, the same painting may also
reveal, unintentionally, much about the workings of the brain: how the
brain recovers the light and space and surfaces that we see. Painters
often stray from photorealistic styles, taking liberties with the rules
of physics to achieve a more effective painting. Critically, some of
these transgressions of physics such as impossible shadows, shapes, or
reflections go unnoticed by viewers – these undetected errors are the
ones that tell us which rules of physics actually count for visual
perception. As artists find the rules they can break without penalty,
they act as research neuroscientists and we have only to look at their
paintings to uncover and appreciate their discoveries. Which means that
40,000 years of art also counts as 40,000 years of documented,
neuroscience research, a record unmatched in any other discipline. We
will survey art from cave paintings to the modern era and show how to
do “science by looking”, unlocking the discoveries in art every time
you give it a painting a second, knowing look.

Predictive spatial coding

The descriptions of surfaces, objects, and events computed by visual
processes are not solely for use in the visual system but are also
passed on to other brain centers to inform them about the surrounding
visual world. Clearly, the description of the visual scene cannot be
sent in its entirety, like a picture or a movie, or each brain module
receiving the description would require some mini-visual system of its
own to interpret it. Some very compressed, language-like version must
be constructed that can be passed on in a format that other centers –
memory, language, planning – can understand. If this is a “visual”
language, what is its grammar? In a simple first pass, we see, among
other things, differences in processing of visual “nouns” and visual
“verbs”. The difference rests on the level of visual attention required
to construct the descriptions for these two categories. The possibility
of a visual language also raises the question of the acquisition of its
grammar from the visual environment and the possibility that this
acquisition process was borrowed and adapted for spoken language.

The language of vision

How do we know where things are? It cannot be just where they land on
the retina, even after correcting for movements of our eyes and head.
Perceived location can deviate dramatically from retinal location.
Interestingly, these deviations often arise when the visual system
predicts where targets should be and in this case we may see the target
where it will be next, even before it gets there. We have found
behavioral evidence of attention benefits at these predicted locations
and we argue that when targets are moving, they are seen ahead of their
actual retinal location to provide accurate targeting if we want to
look at them. Evidence suggests that underlying both the attention and
position representations are saccade maps acting as the “master map of
locations” – for eye movements, for attention, and for perception.
Interestingly, if the saccade system specifies perceived location, it
reverses the usual assumption that action is guided by perception and
suggests instead that perception is doctored in the service of action.
