Paller and Suzuki (2007) Flashcards
two meanings of consciousness
- the subjective experience of the world, resulting from brain activity
- the state or a process of an individaul
elements of consciousness
- subjective point of view; our unique view of the world
- qualia: individual experiences; what things are like for that person
- metacognition: reflect upon thoughts and draw judgement upon them
- inner speech: our verbal narrative of the reasons for and reflections on our behavior
- volition: making and sticking to decisions
dualism
mental (our consciousness) and physical are different substances
reductionism or reductionist views
mental phenomena can be explained via descriptions of physical phenomena
brain region responsible for body awareness
- thalamus
- cortical regions
-angular gyrus
Neuronal Correlates of consciousness theory
-measures the least amount of neural (brain) activity we can look at
social neuroscience theory…consciousness
- to allow us to predict what people are going to do
- predict our own behavior
supramodel integration theory
–connects systems together and allows communication between brain regions that would not be able to communicate with one another on their own
-allows us to overrides some automatic systems or the dominant response
global neuronal workspace model…. consciousness
- arises from when brain regions/ circuits are active
- subjectively experienced brain activity
- different areas responsible for conscious awareness of different types of information
brain regions responsible for consciousness according to GNW
- prefrontal
- inferior parietal cortices
GNW evidence
- Hemineglect patients are unaware of part of the visual
- Patients are unaware of their left visual field, but live their lives normal and sometimes don’t even realize they cant see objects on their left visual field
information integration theory
- proposes shared information itself constitutes consciousness
- we are conscious of many things, but experience all the information as a whole
What is the relationship between the richness of consciousness and the structure of shared information?
-consciousness is highly structured, highly differentiated (informationally rich), and highly integrated
brain regions responsible for consciousness according to ITT
- cortex
- thalamus
ITT evidence
Anesthesia like propofol and xenon disrupt brain’s ability to integrate information by altering neurotransmitter levels
