Higher Cognition III Flashcards
(10 cards)
consciousness
early account: awareness of ourselves and our environment
modern account: cognitive control, linked to conscious access
metacognition + patient
the ability to know and use our cognitive functions
Clive Wearing, only lived in present
Global Workspace theory
Baars (1989)
Conscious Cognitive Content (lol) is globally available for lots of dif processes (attention, memory, etc)
Resembles working memory
Deheane (2006) taxonomy detail
subliminal (unattended)
- little activation (decays after 1-2 seconds)
- no reportability
subliminal (attended) (top down)
- feedforward activation
- no reportability
pre-conscious
- intense activation, but confined to sensori-motor processors
- no reportability
conscious (top down)
- intense activation, this time in frontal-parietal too, global synchrony
- conscious reportability
Deheane (2006) overall
extended.supported the global workspace model to a “neuronal global workspace”, with a testable taxonomy of conscious access
“The transition between preconscious and conscious is sharp, due to this self-amplified non-linear system”
Pros and cons to GWM
pros:
- good computational models
- accounts for the serial nature of conscious experience
cons:
-does not explain nature of consciousness
Del Cul et al. (2007)
Provided very convincing evidence for the model
- Used latency ERP components
- Considered these the best correlate of conscious perception
- has advanced research
What are the 8 functions of consciousness?
- selective attention
- Manipulating information in WM
- Task switching
- response inhibition
- represent contextual information
- Planning
- Metacognition
What is similar/different about these 8 functions?
Similar
- affected by frontal lesions
- show frontal parietal pattern generally
Difference
-the kinds of networks they use
Hugdahl et al. (2015) thing
There is a generalized task-related cortical network for any task that contains general non-specific resources
