Psychology of Consciousness

Study Notes

Consciousness refers to the state of being aware of one's surroundings, thoughts, and feelings.
It is the quality or state of being aware of something within oneself or in the external environment.

Integrated Information Theory (IIT): Consciousness arises from the integrated information generated by the causal interactions within a system.
- Proposed by neuroscientist Giulio Tononi
- Suggests that consciousness is a product of the integrated information generated by the brain
Global Workspace Theory (GWT): Consciousness arises from the global workspace of the brain, which integrates information from various sensory and cognitive systems.
- Proposed by psychologist Bernard Baars
- Suggests that consciousness involves the global broadcasting of information throughout the brain
The Binding Problem: The problem of explaining how the various features of a stimulus are integrated into a unified conscious experience.
- For example, how do we bind together the color, shape, and location of an object into a single conscious experience?

Neural Correlates of Consciousness (NCCs): The specific brain regions and processes involved in generating conscious experience.
- Include regions such as the prefrontal cortex, parietal lobe, and thalamus
- Involve processes such as neural oscillations, synchronization, and integration
Anesthesia and Altered States: Studying altered states of consciousness, such as those induced by anesthesia, can provide insights into the neural mechanisms of consciousness.
- For example, research has shown that anesthesia reduces neural activity in the prefrontal cortex and disrupts neural integration

The Hard Problem of Consciousness: The problem of explaining why we have subjective experiences at all.
- For example, why do we experience the sensation of redness when we see a red apple?
- This problem is considered "hard" because it is difficult to explain why we have subjective experiences in the first place
Dualism vs. Materialism: The debate over whether consciousness arises from a non-physical substance (dualism) or can be fully explained by physical processes in the brain (materialism).
- Dualism posits the existence of a non-physical mind or soul that interacts with the brain
- Materialism posits that consciousness can be fully explained by physical processes in the brain

Dualism and materialism are two opposing views on the nature of consciousness
