Does this sound like the set of challenges you might be facing?
- I’ve got the basics of this down and I’m still drilling it in tidy repetitive blocks because that’s comfortable
- I finish all my reps of one skill before I touch the next, so when they show up jumbled together in real life I freeze
- I drill one topic until it feels easy and move on, and it goes smoothly the whole time
- I drill one topic over and over until it feels totally locked in before moving to the next, and by the end of the block I’m breezing through it
- I can execute the move flawlessly when I know it’s coming and drill it on its own, but in the real situation, where I have to recognize the moment and pick it out of everything else, I freeze on which thing to even reach for.
Practices that may help
- 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.
Contextual Interference: Why Varied Practice Beats Blocked Repetition - 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.
Contextual Interference: Why Varied Practice Beats Blocked Repetition - Convert blocked practice into interleaved practice
Instead of doing all of topic A then all of topic B, shuffle A, B, and C together.
Interleaving: Mix It Up to Learn It Better - Contextual Interference: Why Varied Practice Beats Blocked Repetition
Contextual interference is the performance disruption that occurs when practice conditions are varied or interleaved rather than blocked. Robert Bjork and colleagues showed that despite producing lower performance during acquisition, high-contextual-interference practice (varied, interleaved) consistently produces better retention and transfer on delayed tests than low-interference blocked practice. The difficulty is the mechanism, not the obstacle. - Interleaving topics to disrupt fluency
Mix different topics within a session to prevent the false fluency that blocked practice produces.
The Fluency Illusion: Why Easy Reading Fools You Into Thinking You’ve Learned - Shift from blocked overlearning to interleaved maintenance
After overlearning a skill in isolation, embed it in mixed practice to transfer it to real use.
Overlearning: When Practicing Past Mastery Pays Off - Interleaved pattern practice
Mix multiple pattern types in a single session to sharpen discrimination between chunks.
Chunking: How Experts See What Beginners Miss - 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.
Contextual Interference: Why Varied Practice Beats Blocked Repetition - Interleave different topics during study or work
Mix related but distinct material rather than blocking all of one topic before moving to the next.
Focused vs Diffuse Thinking - Interleave topics within a session
Mix related topics in one session instead of doing all of one before the next.
