Higher Order Theories are a prominent class of scientific frameworks that attempt to explain the nature and mechanisms of consciousness, as evidenced by their inclusion in major academic reviews [1], [2], and [3]. These theories specifically propose that consciousness arises from metacognitive representations of lower-order mental states [4], and they are frequently compared to other models like Global Workspace Theory to evaluate their evolutionary plausibility and neural requirements [5], [6].

Fame in the Brain—Global Workspace Theories of Consciousness psychologytoday.com 2 facts
referenceHigher-Order Theories (HOT) and Global Neuronal Workspace Theory (GNWT) both posit that the prefrontal cortex (PFC) plays a central role in consciousness. However, HOT posits that the PFC's role is to generate a second-order, metacognitive representation of a first-order state (such as one generated by the primary sensory cortex), making the PFC the ultimate source of consciousness. In contrast, GNWT associates consciousness with the function of global broadcasting, whereas HOT does not assign a clear function to consciousness.
referenceMajor theories of consciousness, including Higher-Order Theories (HOT), Global Neuronal Workspace Theory (GNWT), Integrated Information Theory (IIT), and Recurrent Processing Theory (RPT), suggest that neural feedback or recurrent processing mechanisms are necessary for consciousness. These mechanisms originate from different areas depending on the theory: higher-order areas for HOT, the global workspace for GNWT, the posterior hot zone for IIT, and local sensory areas for RPT.
Global workspace theory: consciousness as brain wide information ... selfawarepatterns.com 2 facts
claimGlobal Workspace Theories account for brain injury scenarios where large parts of the cortex are destroyed, suggesting that while the workspace would be reduced, consciousness would persist in a reduced form, unlike higher-order theories which are often dependent on the prefrontal cortex.
claimGlobal Workspace Theories avoid computational redundancies implicit in Higher-Order Theories of consciousness, which the author suggests are unlikely from an evolutionary perspective.
