Study Notes

Consciousness: Examples

Demonstrates feelings like pain, tasting, and sadness.
Illustrates the feeling of thinking.
Shows the feeling of thinking about oneself.

Materialism and its Alternatives

Materialism: Mind/Body are the same, and mind is product of physical processes.
Problems for Materialism: The explanatory gap, The knowledge argument.
Liebniz Monadology: Perception is inexpicable by physical processes.
Mary's knowledge argument: Mary knows all the physical facts, but upon leaving the room, she learns a new fact about consciousness. Thus, there are facts about consciousness which are not physical facts.

Alternatives to Materialism

Dualism: Mind/Body are distinct and separate. Both can cause action in the other.
Epiphenomenalism: The mind is caused by the body, but the mind never causes any action on the body.
Russellian Monism: The mind and the body are the same thing. There is no separate mind or body, only one underlying reality.

Testing for Consciousness

Consciousness without report: Change blindness (seeing something and not noticing a change), visual neglect (ignoring stimuli from the side of the body that is affected by a neurological problem).
Behavior without consciousness: Blindsight (acting upon stimuli that you are not consciously aware of), subliminal priming (acting on subliminal stimuli).
There are cases of behavior without report, like blindsight and change blindness.

Scientific Theories of Consciousness

Higher-order theory (HOT): Consciousness involves a high-order representation of lower-order mental states. Global Workspace Theory:
- Conscious thought arises from a broadcast of information to neurons, causing the brain to work together.
- This occurs in a global workspace, a network in the brain.
- Ignition of the global workspace, where local processors' activity becomes mobilized.
- The global workspace theory is one of many theories on consciousness.
Integrated Information Theory: Concepts like integrated structure, complex neuron networks, and posterior cortical hot zones.
Re-entry and Predictive Processing: Prediction, top-down, and bottom-up predictions.

Hard Cases: Split Brain

Hard questions:
- Are each hemisphere conscious?
- Which hemisphere is conscious, if not both?
- If both are conscious, do they represent different persons?
- If not, how can the person have two streams of consciousness?
Questions on integrating our unified idea of consciousness.

Consciousness and Free Will

Introspection and consciousness
Libet's experiment: The brain prepares for action before awareness of intention, making free will problematic.
