In philosophy, there are two main types of functionalism: psychological functionalism, which focuses on the mind and mental states as functions that can be understood through their role in cognitive processes; and biological functionalism, which examines the functions of biological systems and processes in living organisms. Both types emphasize the importance of understanding how systems work rather than their physical properties.
