Feedback seeking is a critical learning process wherein students elicit information from GenAI or human sources. Guided by self-determination theory, this study explores how students’ feedback seeking experiences shape their diverse motivation development. Interviews with university students reveal how interactions with GenAI, teachers, and peers influence subsequent intrinsic motivation, extrinsic motivation, and amotivation to seek feedback. The findings suggest insights to support students’ autonomous motivation and feedback seeking skills from both GenAI and humans.
