Actors appeared to pose expressions that changed incrementally along three progressions: neutral‐to‐fear, neutral‐to‐anger, and fear‐to‐anger. Across all three morph types, adults displayed more sensitivity to subtle changes in emotional expression than children and adolescents. Fear morphs and fear‐to‐anger blends showed a linear developmental trajectory, whereas anger morphs showed a quadratic trend, increasing sharply from adolescents to adults …
