PROBLEM TO BE SOLVED: To provide an emotion recognition device, an emotion recognition method, and an emotion recognition program capable of discriminatingly recognizing aggressiveness of anger from discomfort of anger.SOLUTION: An emotion recognition device 10 includes: a first detection part 11 that detects a central nervous system reaction (brain waves of the left brain and brain waves of the right brain) of a user； a second detection part 13 that detects an autonomic nervous system reaction (heartbeat) of the user； and a recognition part 15 that recognizes aggressiveness (intensity of state aggressiveness) of the user's anger on the basis of a central nervous system reaction (a ratio between an &alpha； power value of the left brain and an &alpha； power value of the right brain) and an autonomic nervous system reaction (the number of heart beats).【課題】怒りの攻撃性を、怒りの不快感と区別して認識することができる情動認識装置、情動認識方法、及び情動認識プログラムを提供する。【解決手段】情動認識装置１０は、ユーザの中枢神経系反応（左脳の脳波、及び、右脳の脳波）を検出する第１検出部１１と、ユーザの自律神経系反応（心拍）を検出する第２検出部１３と、中枢神経系反応（左脳のαパワー値と、右脳のαパワー値との比）及び自律神経系反応（心拍の数）に基づいて、ユーザの怒りの攻撃性（状態攻撃性強度）を認識する認識部１５と、を備える。【選択図】図１
