Dear all,
This is to remind you that the next talk in the CEU Cognitive Science
seminar series will by given by:
*Gerry Altmann* *(The **University of York)*
Date: Wednesday, January 15, 2013, 5 PM
Location: Cognitive Development Center, Hattyú u. 14, 3rd floor
*Title:* Representing objects across time: eye movement and fMRI studies of
language-mediated event representation.
Language is often used to describe the changes that occur around us –
changes in either state (“I cracked the glass…”) or location (“I moved the
glass onto the table…”). To fully comprehend such events requires that we
represent the ‘before’ and ‘after’ states of the object. But how do we
represent these mutually exclusive states of a single object at the same
time? I shall summarise a series of studies, primarily from fMRI, which
show that we do represent such alternative states, and that these
alternative states compete with one another in much the same way as
alternative interpretations of an ambiguous word might compete. These
studies also show that whereas the representations of distinct but similar
objects (e.g. a glass and a cup) interfere with one another in proportion
to their similarity, representations of the distinct states of the same
object interfere in proportion to their dissimilarity. This interference,
or competition, manifests in a part of the brain that has been implicated
in resolving competition. Furthermore, activity in this area is predicted
by the dissimilarity, elsewhere in the brain, between sensorimotor
instantiations of the described object’s distinct states. I shall end with
new data (still too hot to touch) whose interpretation is a first step
towards a brain mechanism for distinguishing between object types, tokens,
and token-states.
PLEASE NOTE: Our seminar room has a limited capacity. Please arrive early
to ensure you get a seat. The talk will begin promptly at 5.
