Magda Blondiau Arnold (born Magda Barta-Blondau; December 22, 1903 – October 5, 2002)[2] was a Canadian psychologist who was the first contemporary theorist to develop appraisal theory of emotions, which moved away from "feeling" theories (e.g. James-Lange theory) and "behaviorist" theories (e.g. Cannon-Bard theory) toward the cognitive approach.[3][4] She also created a new method of scoring the Thematic Apperception Test called Story Sequence Analysis.
She was a 1957 Guggenheim Fellow.[5]
