The stance of functionalism is to study psychological events and those past and current stimuli that evoke them. In other words, functionalism studies the way in which psychological events are programmed.
In other words functionalism says we can't work without society and identity theory says sometimes person thinks about themselves, this phenomena depends on circumstances.
Functionalism sees mental states as constituted by their functions, while (type) identity theory (aka “reductive materialism”) generally sees mental states as identical with brain states. So, identity theory is an expressly physicalist view and functionalism is not.
