機能主義
ウィリアム・ジェームズ、ジョン・デューイ、チャールズ・サンダース・パースは、ダーウィンの自然淘汰による進化論に大きく影響を受けた機能心理学の創始者です。この理論は、行動を含む個体の特性が自然選択を通じて環境に適応することを示唆しています。機能主義の中心にある概念は適応であり、これは特性が個体の生存と…
機能主義は、ウィリアム・ジェームズによって導入された考え方の学派であり、ダーウィンの自然選択による進化論の影響を受けています。
機能主義者は、記憶、感情への反応、言語能力など、精神的プロセスのさまざまな側面を研究して、多様な環境での個人の生存と適応におけるそれらの役割を理解します。
例えば、機能主義者は、空腹や喉が渇いたときに貯蔵された食物や水の場所を思い出すことで、個人の記憶が生存にどのように役立つかを探ります。
同様に、彼らは、恐怖の感情が個人に危険の兆候を警告し、適切な生存本能を使用するように促す方法を調べます。
さらに、機能主義者は、言語がコミュニケーション、協力、社会的絆をどのように育むかを研究します。これらはすべて、グループ内での個人の生存に不可欠です。
心が特定の方法で「なぜ」働くのかに焦点を当てることで、機能主義者は、その思考と行動の背後にある理由と目標を理解することを目指し、心を部分的にではなく全体として研究することを好みます。

Q1: Who founded functionalism and what influenced its development?
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.
Q2: How does functionalism differ from structuralism in studying the mind?
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.
Q3: What role does adaptation play in functionalist psychology?
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.
Q4: How do functionalists explain the survival value of memory?
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.
Q5: Why do functionalists consider emotion important for human survival?
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.
Q6: What adaptive functions does language serve according to functionalism?
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.
Q7: How does functionalism relate to contemporary psychology?
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.
