Log whether the task was completed or needs another sprint.
The Evidence
Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.
The Effect of Task Interruption on Working Memory Performance↗
Task interruptions impaired performance and created measurable resumption costs.

Measurable Outcomes
Related Protocols
Dopamine Management
Reduce baseline dopamine drains (social media, constant novelty) to maintain motivation and focus capacity. Strategic boredom rebuilds dopamine sensitivity.
40Hz Binaural Beats for Focus
Listen to 40Hz binaural beats through stereo headphones during work. Gamma-frequency entrainment is associated with improved attention, working memory, and neural synchrony.
Notification Shutdown Block
Disable non-essential notifications during one protected focus block to reduce interruption costs.
Mindfulness Attention Primer
Use 5 minutes of breath-focused mindfulness before cognitively demanding work.
