William James, John Dewey, and Charles Sanders Peirce founded functionalism, heavily influenced by Darwin's theory of evolution by natural selection. James envisioned psychology's role as investigating how behavior functions in the world. This evolutionary perspective shaped functionalism's focus on understanding why the mind works in certain ways rather than simply describing its components.

Functionalism focuses on the mind's overall operation and adaptive purposes, while structuralism emphasizes the components of the mind. Functionalists ask 'why' questions about mental activities' roles in survival and adaptation, whereas structuralists ask 'what' questions about mental parts. James promoted introspection to understand the continually changing stream of consciousness, rejecting structuralist methods.

Adaptation is central to functionalism, meaning traits enhance an individual's chances of survival and reproduction. Functionalists apply Darwin's natural selection theory to psychological traits, positing that thoughts, feelings, and behaviors evolved for survival benefits. They investigate how mental activities enable individuals to adapt to their environments, identifying the adaptive functions these psychological characteristics serve.

Functionalists study memory as a mental process crucial for survival and adaptation. Memory aids survival by enabling individuals to recall locations of stored food and water when hungry and thirsty. By understanding how memory functions to support basic survival needs, functionalists demonstrate the adaptive purpose of this cognitive ability in diverse environments.

Functionalists examine emotions like fear as adaptive responses that alert individuals to danger signs and prompt appropriate survival instincts. Rather than studying emotion as an isolated component, they focus on its functional role in protecting individuals from threats. This perspective reveals how emotional responses have evolved to enhance survival chances in threatening situations.

Functionalists study language as a mental ability that fosters communication, cooperation, and social bonding—all crucial for individual survival within groups. Language enables humans to share information, coordinate activities, and build relationships necessary for group living. By examining language's functional role in social adaptation, functionalists demonstrate how this ability supports both individual and collective survival.

Functionalism established by James, Dewey, and Peirce remains foundational to contemporary psychology, which continues exploring how mental processes enable adaptation. The functionalist emphasis on understanding psychological traits' adaptive purposes and studying the mind holistically influences modern approaches. Contemporary psychology builds on functionalism's evolutionary perspective, investigating how behaviors and mental activities serve survival and adaptation functions.
