Valence–arousal plane

效价–唤醒度平面（Valence–Arousal Plane），由 valence（情感正负性）与 arousal（生理激活程度）两轴构成的二维空间，用于表征和比较情绪状态。

English Definition

"The two-dimensional continuous space defined by valence (positivity/negativity of affect) and arousal (physiological activation level), used to represent and compare emotion states."

用法说明 · 针对中文母语者

基于 circumplex model of affect；agent 系统常把用户和 agent 的情绪映射到该平面上计算距离或同步关系。中文文献中也直接称「VA 平面」。

常见错误

·arousal 不是「唤醒」的情绪，而是生理激活/警觉维度，不要译为「激动度」
