Evidence having the most direct bearing on this is "contrastive analysis"—a set of Can we make progress exploring consciousness? Or is it forever beyond human reach? In science we never know the ultimate outcome of the journey. Far from being some free-floating cloud around our heads, sensory consciousness is profoundly embedded in biology, anatomy, physiology, and above all, in adaptive brain functions that serve us in every second of waking life.

Global workspace architecture can be described informally as a "working theatre," where focal consciousness acts as a "bright spot" on the stage, directed by the selective "spotlight" of attention. GWT proposes that information in the brain becomes conscious when broadcast across a "global workspace.   While integrated information theory focuses more on identifying whether an organism is conscious, the global workspace theory offers a much broader approach to understanding how consciousness works. Mar 5, 2024 · The global workspace theory (GWT) 58 describes the processing steps that give rise to conscious experience as a dynamic interaction between local processors and a global workspace that integrates information and broadcasts it to other processors for further processing. Consciousness in its entirety, they argued, was too broad and Sep 7, 2020 · The Global Neuronal Workspace Theory (GWT) is a cognitive theory of consciousness with neuronal correlates, according to which the latter is tantamount to global information availability (Dehaene and Naccache 2001).

Global Workspace Dynamics of conscious experience is supported by brain evidence, particularly the role of the cortex and thalamus. A Brief Overview. Bernard J. Any theory of conscious processing should enable specific predictions regarding pharmacological, pathological, and physiological states in which the level of consciousness is disrupted.
