Definition

Memory coherence or connectivity is the degree of meaningful connectedness of knowledge. If you visualize knowledge as a semantic network, coherence will reflect the quality of connectedness between proximal nodes of the network. Concepts such as cat and dog are semantically close. Reversely, cat and algebra are usually remotely connected. High knowledge coherence improves memory via consolidation in sleep. It reduces knowledge interference and favors memory consistency.

Free learning

Coherent knowledge enables fast thinking. Reliance on the learn drive leads to learning based on high coherence due to the instantaneous evaluation of prior knowledge. Reliance on schooling leads to knowledge of low coherence. Free learning is the simplest and cheapest way to ensure high coherence. Coercion in learning leads to low coherence for it violates the Fundamental law of learning. For an advanced student, the best approach to free learning with high coherence is incremental reading.

Sleep and creativity

Coherent learning is facilitated by short semantic distances in the concept network, and axonal-dendritic overlap in network topology.

Coherent knowledge facilitates creativity. A stable coherent framework of knowledge can be used to attach rich pieces of new knowledge, and to form local and remote associations between different concepts.

In the Neurostatistical Model of Memory, coherence affects the buildup of memory stability in waking and in sleep (see: Two-component model of memory stability).

Memory: Coherence vs. Consistency
Memory: Coherence vs. Consistency

Figure: Coherence and consistency of memory can easily be confused. Coherent memories show high connectedness. Meaningful memories with a short semantic distance are highly coherent. Consistency of memory indicates low degree of memory conflict. In coherent networks, consistency is well preserved, however, reasoning may lead to a conflict that will result in changes (e.g. forgetting by interference). Both coherence and consistency are gradually improved by knowledge darwinism. Both improve knowledge stability and lead to high quality long-term memories
