## Items

- [Biological Prime Time](https://timetrack.works/th/items/biological-prime-time) — Productivity concept of identifying your personal peak performance hours through energy tracking, then scheduling most important work during these high-energy periods for 20-40% productivity boost.
- [Context Switching Cost](https://timetrack.works/th/items/context-switching-cost) — The productivity loss and mental fatigue incurred when switching between different tasks, projects, or applications. Research shows 23-minute recovery time per switch and up to $450 billion annual economic cost.
- [Attention Residue Effect](https://timetrack.works/th/items/attention-residue-effect) — Cognitive phenomenon identified by researcher Sophie Leroy in 2009 where part of our attention remains focused on a previous task even after switching to a new one. This residue impairs performance on the current task, with studies showing it takes an average of 23 minutes to fully regain focus after distractions. The ready-to-resume plan technique can mitigate this effect.
- [Shallow Work Concept](https://timetrack.works/th/items/shallow-work-concept) — Non-cognitively demanding, logistical tasks performed in a state of distraction, as defined by Cal Newport. Shallow work includes activities like answering emails, attending meetings, and administrative duties that don't create significant new value or require deep concentration. Understanding shallow vs deep work helps optimize time allocation for maximum productivity.
- [Time Confetti Phenomenon](https://timetrack.works/th/items/time-confetti-phenomenon) — Term coined by author Brigid Schulte describing fragmented bits of time scattered throughout the day that are difficult to use productively. Time confetti results from constant interruptions, notifications, and multitasking that shred workdays into unproductive start-stop patterns. Research shows it takes 23 minutes to return to original tasks after interruptions.
- [Time Confetti](https://timetrack.works/th/items/time-confetti) — Concept by Brigid Schulte describing fragmented moments lost to unproductive multitasking, where interruptions taking 23 minutes to recover from reduce productivity and increase burnout.
- [Cognitive Tax 2026 - Attention Fragmentation](https://timetrack.works/th/items/cognitive-tax-2026-attention-fragmentation) — The substantial mental burden modern workers face from constant digital interruptions every few minutes, representing an attention economy challenge that predecessors never encountered.
