A desirable difficulty is a learning task that requires a considerable but desirable amount of effort, thereby improving long-term performance. It is also described as a learning level achieved through a sequence of l...
Difficulties that require more effort from learners may impede short-term learning but are ultimately beneficial for long-term learning and are therefore termed DesirableDifficulties.
Jun 6, 2025 · Effortless learning isn't learning. Real expertise needs the right kind of struggle: what cognitive scientists call “desirabledifficulties.” Learn how to apply them.
Nov 3, 2025 · They discovered what they call “desirabledifficulties”—specific challenges that make learning feel harder during training but dramatically improve retention and transfer afterward.
Desirable difficulties are learning conditions that require extra mental effort and may temporarily reduce performance, but lead to better retention and understanding over time.
Many difficulties are undesirable during instruction and forever after. Desirabledifficulties, versus the array of undesirable difficulties, are desirable because they trigger encoding and retrieval processes that sup...
Mar 14, 2026 · A difficulty is only “desirable” if the learner can actually engage with it productively. When the material is already overwhelming, with many new concepts that all interact with each other, adding more...
Feb 19, 2026 · Desirable difficulties are learning conditions that make the initial study process feel harder but lead to better retention over the long term. Coined by Robert Bjork, these include strategies like spac...
Sep 11, 2023 · But what counts as a “desirabledifficulty” versus plain difficult? The Bjorks list spaced learning among strategies that introduce desirabledifficulty: it disrupts the flow of learning, allowing pupils ...
Dec 1, 2020 · For example, the notion of desirabledifficulties (e.g., Bjork & Bjork, 2020) reflects the idea that requiring effort during learning better supports learning than more passive approaches.
