Functional systems theory and the activity-specific approach in psychological taxonomies

This brief opinion contribution reflects on the application of Anokhin's functional systems theory in the development of models of temperament in Russian differential psychophysiology. It points to the benefits of using an activity-specific approach in temperament theory. This approach suggests separating traits related to physical, communicative and mental aspects of behaviour.
