TPR

Asher observed that children learn their first language by physically responding to speech long before producing it themselves.

Three hypotheses drive TPR: the brain is predisposed to learn language by listening first (speech should emerge naturally, never be forced); language learning engages the right hemisphere via physical movement; and learning should be stress-free, since stress and negative emotion inhibit acquisition.

TPR is a "comprehension approach": grammar is acquired by induction from input, not taught directly.

Asher's "believability" claim: comprehensible input with high believability produces long-term memory, compared to short-term memory for low-believability input — TPR works because it creates intimate, personal experiences.

Oflaz (2019) found TPR significantly reduced learner anxiety and increased willingness to speak.

Spokn's story-generation prompt explicitly instructs: "Follow Total Physical Response principles — emphasise what characters DO physically... If a character is nervous, describe their hands."

The app's "act out with your body" guidance tells learners to gesture, move, and use their face while listening and speaking — applying TPR directly, by the learner, at home.

Spokn applies TPR's principles in a self-study audio format — it is not classroom TPR with a teacher giving live physical commands. Standard criticism of TPR: it's most useful at beginner level and can lean heavily on imperatives.
