A plain glossary of focus
The vocabulary that gets used around attention and procrastination, defined without the mysticism — including where each idea came from and which parts of the popular version the evidence does not support.
Every entry names its source and carries a caveat, because a surprising amount of what circulates in this area is a real finding that has been stretched, or a memorable study that later failed to replicate. Where that is the case, the entry says so rather than repeating the confident version.
- Executive dysfunctionDifficulty with the set of mental processes that carry you from intention to action: holding a goal in mind, planning the steps, starting, switching, and stopping.
- Task initiationThe executive function that converts a decision into a first action — the step between knowing what to do and beginning it.
- Attention residueThe portion of attention that remains on a previous task after switching to a new one, degrading performance on the new task.
- Context switchingMoving between tasks that require different mental context, paying the cost of unloading one and reloading another.
- Deep workProfessional activity performed in a state of distraction-free concentration that pushes cognitive capability toward its limit.
- Flow stateA state of complete absorption in an activity, in which attention holds itself, self-consciousness recedes, and the sense of time distorts.
- HyperfocusIntense and prolonged absorption in a single activity, difficult to interrupt or redirect, often on something that was not the priority.
- Time blockingAssigning specific work to specific hours in advance, so the day is decided before it is lived rather than negotiated as it goes.
- Decision fatigueThe proposal that the quality of decisions declines over a long sequence of them, as a limited capacity for self-control is used up.
- Analysis paralysisOver-analysing a decision to the point that no choice is made, and the cost of delay exceeds the difference between the options.
- Task paralysisBeing unable to start despite knowing what the task is, how to do it and that it matters. It is a freeze at the threshold rather than a lack of ability or intent.
- Attention spanHow long attention can be sustained on one thing — a figure that varies enormously with the task, the person, and how interesting the thing is.
- Working memoryThe system that holds and manipulates a small amount of information in mind while you use it — the desk you work on, not the cabinet you store things in.
- Cognitive loadThe demand a task places on working memory — split between what the material inherently requires and what the way it is presented adds on top.
- Implementation intentionsA plan in the form "when situation X arises, I will do Y" — deciding in advance exactly when and where a behaviour happens rather than leaving it to the moment.
- Social facilitationThe finding that the presence of others improves performance on simple or well-practised tasks and can worsen it on complex or unfamiliar ones.
- Parkinson's LawThe observation that work expands so as to fill the time available for its completion.
- Zeigarnik effectThe proposal that interrupted or unfinished tasks are recalled better than completed ones, because the mind keeps them active.
- ProcrastinationVoluntarily delaying an intended action despite expecting to be worse off for the delay.
- Pomodoro TechniqueA time-boxing method: twenty-five minutes of single-tasking, a five-minute break, and a longer break every fourth round.
- MonotaskingDeliberately doing one thing at a time, with the alternatives closed rather than merely resisted.
- Rejection sensitive dysphoriaAn intense, often physically felt emotional reaction to perceived or actual rejection, criticism, or falling short of one’s own standards.
- Dopamine menuA prepared list of activities to reach for when you need stimulation or a break, written in advance so the choice is not made in the moment.
- Eat the frogA method of giving an important, often avoided task an early protected place in the day.
- Habit stackingAttaching a new behaviour to an existing reliable one, so the old habit becomes the cue for the new: after X, I will do Y.
- TimeboxingAllocating a fixed period to a task and stopping when it expires, whether or not the task is complete.
- Ultradian rhythmA biological cycle shorter than a day. In productivity writing it usually means a proposed ninety-minute cycle of alertness and fatigue during waking hours.
- Interest-based nervous systemThe idea that attention and motivation are driven by interest, novelty, challenge and urgency rather than by a task’s importance or consequences.
- Attention restorationA theory that exposure to natural environments can help restore aspects of directed attention after mental effort.
- Shut up and writeA group writing session in which people work silently on their own writing for a fixed period, with a short check-in before and after.
- Brain fogA non-medical term for slowed or unclear thinking: difficulty concentrating, finding words, holding something in mind, or feeling mentally present.
- Time blindnessAn informal description of difficulty noticing elapsed time or estimating how long an activity will take.
