According to Augustinavičiūtė, humans can be classified in terms of types of information processing, or "information metabolism". Psychological features such as attention, interests, memory and motivation are components of this theory of information metabolism. This theory of information metabolism is built upon an analogy to energy metabolism. According to this analogy, information that arrives as signals from outside an organism are available for information metabolism just as food is available for energy metabolism. The brain is the key information metabolism system. The brain and information metabolism deal with a two-way flow of signals: metabolism of input signals results in the production of output. Just as enzymes can constructively interact only with structurally specific substrate molecules, brains can only constructively metabolize information that is correctly "tuned" to the brain. By assigning "energy values" to the various psychological components of information metabolism, Augustinavičiūtė created a mathematical theory of thinking.
