Consciousness Research at UNICOG
An organized bibliography of our research and main
publications in the domain of conscious versus non-conscious processing
Since
about 1995, with a large number of collaborators, Stanislas Dehaene has been studying
access to consciousness. The research has both empirical and theoretical sides.
With Lionel Naccache,
Claire Sergent, Raphaël Gaillard, Laurent Cohen
Sid Kouider, Jérôme
Sackur, and many
others, a variety of behavioral
and neuroimaging
experiments have been performed to study the contrast between subliminal versus
conscious processing of masked words and digits. With Jean-Pierre Changeux,
Stanislas Dehaene has been
developing a global neuronal workspace theory of conscious access,
including detailed neuronal network simulations.

Experiments on subliminal
processing
Over the years, we have used
subliminal priming with masked numbers and words as a major tool to study
non-conscious processing using both psychological and brain-imaging methods. We
continue to use subliminal processing to infer the depth of non-conscious
processing and thus to obtain a “mirror image”, as it were, of the cognitive
operations that require consciousness.
Results up to 2003 were summarized

Modelling
The
following paper first introduced, in a formal model, the “global neuronal
workspace” model of conscious access:
Stanislas Dehaene, M. Kergsberg, and J. P. Changeux. A neuronal
model of a global workspace in effortful cognitive tasks. {Proceedings of the National Academy of Sciences USA},
95:14529--14534, 1998. [PDF ]
Two
other more recent paper explored how this model could explain basic data on
conscious data, particularly during the attentional
blink and inattentional blindness:
Stanislas Dehaene and Jean-Pierre
Changeux. Ongoing spontaneous
activity controls access to consciousness: a neuronal model for inattentional blindness.. PLoS Biol,
3(5):e141, May 2005. [WWW]

Changeux. A neuronal network model linking subjective
reports and objective physiological data during conscious perception. {Proceedings of the
National Academy of Sciences
USA},
100:8520--8525, 2003. [PDF ]
The
workspace model can be seen as the outcome of a long-term modelling project in collaboration
between Stanislas
Dehaene and Jean-Pierre Changeux, aiming at a better
understanding of the contribution of prefrontal cortex to various cognitive
tasks. The general principles guiding this work have been described a long time
ago in :

33:63--109, 1989.
