Study Notes
Defining + Studying Consciousness
- Two major approaches to understanding consciousness: "easy" and "hard" problems.
- The easy problem focuses on how brain activity relates to conscious experiences, which is scientifically testable.
- The hard problem focuses on understanding subjective conscious experiences which is harder to test scientifically.
- Qualia is the 'what it's like' component of consciousness, which considers the difference in subjective experiences.
- Attention, awareness, and consciousness are related.
- The tripartite model of awareness suggests three stages: subliminal processing, preconscious processing, and conscious processing.
- The tripartite model highlights the interplay of exogenous and endogenous factors.
Theories of consciousness
- The Global Neuronal Workspace (GNW) theory suggests that widespread processing of information underpins conscious experiences.
- The GNW theory proposes that unconscious processes involve local sensory-motor processing, while conscious processes involve widespread processing and integration of cognitive networks.
- The Integrated Information Theory (IIT) proposes that consciousness arises from complex systems.
- The IIT explains which types of systems have consciousness and how much they have.
- The IIT highlights the role of feedback loops in modifying information and creating complexity, leading to consciousness.
- IIT posits that the specific architecture of the brain, not just specific brain regions, contribute to consciousness.
- The cerebellum is a case study supporting the IIT.
Trance reflects shifts in direction of cognition
- Hove et al. (2016) explored trance states and their effects on brain activity using fMRI in experienced shamans.
- The study used rhythmic drumming to induce a trance state.
- Results indicate increased activity in the default mode network during a trance state, suggesting a shift towards inward-directed cognition.
- The study also found a decreased connection between auditory processing regions, suggesting perceptual decoupling and less intrusion from external stimuli into conscious awareness.
LSD affects language category representation
- Family et al. (2016) studied the effects of LSD on language category representation.
- Concepts from similar categories tend to interfere with each other in normal states.
- LSD alters this pattern, leading to less interference between concepts from similar categories.
- LSD may disrupt the brain's typical organization of language categories, leading to less interference.
