Practice the same skill in different physical and social contexts
Vary the environment, time of day, or social setting of your practice so the skill is not bound to a single context.
Why it works
Context-dependent memory is a well-established phenomenon: skills and knowledge encoded in a specific context are more easily retrieved in that same context. When a skill is only practiced in one setting, it becomes partially context-bound — accessible when the cues match, but less available when they don’t. Varied-context practice prevents this over-fitting by reducing the weight of any single contextual cue in the retrieval pathway.
How to do it
- Identify the contexts in which you currently always practice (same desk, same time, same tools).
- Deliberately move at least some practice sessions to a different location, time, or format.
- Practice the skill in the kind of contexts where you’ll actually need it (e.g., in front of others if the skill is social).
- Over time, accumulate practice across enough varied contexts that no single context becomes necessary for access.
Evidence
Context-dependent memory effects are well documented in the learning literature (Godden & Baddeley, 1975 is a classic underwater study). Varying study/practice context has been shown to reduce context-specificity and improve transfer. Smith, Glenberg, and Bjork (1978) extended this to ordinary rooms — showing that studying the same material across two different environments raised later recall over studying twice in one, which is the direct basis for practicing across varied settings.

The practical implication of varied-context practice is well supported; the precise quantification of how much variation is optimal is less established.

Common mistake
Assuming that a skill practiced deeply in one context will fully transfer to different contexts automatically — the transfer depends on having practiced across contexts.

More practices for Contextual Interference: Why Varied Practice Beats Blocked Repetition
- Switch to a new variation before mastering the current one
Move to a different variation or task before you feel fully comfortable — the premature switch is what drives deeper encoding.
- Interleave practice across different skill types within a single session
Mix practice across multiple distinct skills in a session rather than completing all repetitions of one skill before moving to another.
- Schedule random practice for retention goals, blocked practice only for initial acquisition
Use blocked repetition to learn a new movement or concept, then immediately shift to random practice once the basics are present.
- Calibrate practice difficulty so it is challenging but not overwhelming
Aim for 60–85% success rates in practice — not perfection, and not near-failure.
- Distribute practice sessions across days rather than massing them
Four 30-minute sessions across a week produce more durable skill than one 2-hour session, even at equal total time.
