Abstract
This paper introduces the Type 1 / Type 2 consciousness framework, a theoretical distinction grounded in a sustained phenomenological case study of over seven years. The framework proposes two fundamental modes of conscious experience, differentiated primarily by the involvement of the Default Mode Network (DMN). Type 1 consciousness is characterized as pre-narrative awareness with minimal DMN activity: whole-field perception without object segmentation, self-referential processing, or temporal experience. Type 2 consciousness represents the typical adult human mode, mediated by the DMN, featuring spontaneous self-referential thought, mental time travel, linguistic categorization, and narrative identity construction.
This framework is applied as a new interpretive lens to ten major unresolved questions in consciousness studies: the Hard Problem, the Binding Problem, Neural Correlates of Consciousness, Qualia, Free Will, the Self, Memory and Consciousness, Time and Consciousness, Unity of Consciousness, and Attention and Consciousness. For each question, the paper describes how the Type 1 perspective generates novel hypotheses and reframes existing assumptions. An eleventh question regarding animal consciousness and DMN evolution is also introduced.
The paper does not claim to resolve these questions definitively. Rather, it offers first-person phenomenological observations from a rare and sustained altered state of consciousness that may complement existing neuroscientific and philosophical approaches. The hypotheses generated here are intended to stimulate empirical investigation and interdisciplinary dialogue.
