Behavioral Investment Theory
A Theory of the Mind-Brain-Animal Behavior Relation
Behavioral Investment Theory (BIT) is the third key idea in the Unified Theory Of Knowledge. It is a theory of the mind-brain-behavior relation, and it provides the metatheoretical framework for the evolution of Mind, the third plane of existence on the ToK System. It gives rise to a neurocognitive functionalist view of mental behavior and a model of the cognitive architecture of the human mind in four levels (reactive, operant, imaginative, linguistic).
