Key issues and insights relevant to our discussion of AI consciousness and service
| Concept | Illustrative paper | Definition | Consciousness mechanism |
|---|---|---|---|
| Neuroscience | |||
| Global Processing Theories | |||
| Neuronal Synchrony Theory | Singer (1999) | Consciousness arises when neural groups synchronize firing patterns | Synchronization of neural rhythms across different brain regions is proposed to bind conscious experience |
| Integrated Information Theory | Tononi (2004) | Consciousness is a product of integrated information, measured by Φ | High Φ indicates a “greater amount” of consciousness |
| Attention Schema Theory | Graziano (2013) | Consciousness is the brain’s model of its own attention processes | The brain’s “attention schema” models where attention is directed, creating conscious experience |
| Local Processing Theories | |||
| Micro-consciousness Theory | Zeki (2007) | Awareness occurs in specific regions of the brain, rather than globally | Different areas of the brain create micro-consciousnesses (e.g. color, motion, or shape) |
| Recurrent Processing Theory | Lamme (2006) | Consciousness arises from feedback processing within neural areas | Local sensory processing with feedback loops between lower and higher areas of the visual system |
| Predictive Processing | Hohwy (2013) | The brain is constantly predicting sensory inputs, updating its prediction models based on prediction errors | Reconciliation of a local state (e.g. sensory inputs) and global state (e.g. sense of self) via prediction-error minimization |
| Cognitive Science | |||
| Feature-integration Theory of Attention | Treisman and Gelade (1980) | Conscious perception of objects is the integration of different features (e.g. color) through attention | Attention binds different features into a single perception of an object |
| Higher-order Theories | Rosenthal (2005) | A mental state becomes conscious when it is the object of a higher-order representation (thought or perception) about that state | Higher-order thoughts about first-order states generate consciousness (e.g. awareness of own thoughts) |
| Global Workspace Theory | Baars (1993) | Consciousness arises from information broadcast across a brain’s workspace | Neuronal activation patterns spread across multiple brain regions, enabling widespread access to information |
| Natural Sciences | |||
| Physics | |||
| Orchestrated Objective Reduction | Hameroff and Penrose (1996) | Consciousness comes from quantum processes in brain cells, where processes lead to consciousness | Quantum states in microtubules collapse to create awareness |
| Evolutionary Biology | |||
| Unlimited Associative Learning | Ginsburg and Jablonka (2019) | Conscious experiences are an evolutionary adaptation that enables open-ended learning | Formation of complex, context-sensitive associations between stimuli, responses, and contexts |
