Using Psychophysiological Data to Facilitate Reflective Conversations with Children about their P...
summary
Lab sessions collect psychophysiological signals (webcam facial expressions, eye tracker, ear‑clip PPG heart rate, forearm GSR) while 68 participants aged 7–13 play Rocket League and LEGO Builder’s Journey, then 35 are interviewed with a synchronized biofeedback replay of gameplay, webcam and signals. Biofeedback prompts produce concrete reflections: challenge followed by success yields pride and joy, failure yields frustration, responses range from single words to detailed self‑talk, and children interpret facial > heart rate > GSR cues most easily.
