Main evidence and numbers
| Result | Wetin dem measure | Why e different |
|---|---|---|
| Time before person return to task | E include other work and choices wey happen in between | No be continuous time wey person no fit focus |
| Time to resume | Time to start again after interruption end | E depend on the task and memory of wetin person wan do |
| Attention residue | Wetin remain from the task wey person do before | E fit affect performance, but no fixed timer dey |
The field study look how people organize work; e no show one universal body reset time. Person fit do other tasks before e return to the one wey interruption stop. If you treat all that time as time wey person no fit concentrate, you don change wetin dem measure. Mark et al., 2005
Wetin laboratory research on resuming task show?
Trafton and the other researchers compare interruption wey happen sharp-sharp with one warning condition wey give people eight seconds before the interruption start. People wey get warning prepare more and resume quicker. This support the idea say planning ahead and remembering the first goal fit help; e no show one recovery time wey always be the same. Trafton et al., 2003
Altmann and Trafton model explain how making a goal active and remembering am fit affect restarting. Leroy experiment look attention residue when people leave unfinished work to do another thing. These explanations concern processes wey connect but no be the same, so no join their measurements into one universal minute estimate. Altmann et al., 2002 Leroy, 2009
Person fit make up for interruptions?
For the experiment by Mark and the other researchers, people wey dem interrupt finish tasks quicker, and the quality no change, but dem report more stress, vex, time pressure and effort. So finishing quicker no prove say interruption no cause harm. This show again why one measure of productivity no tell the whole story. Mark et al., 2008
Wetin dey affect am?
Every break dey the same as interruption?
No. Planned rest break and unexpected request to do another task fit get different purpose and demand. The microbreak meta-analysis find small benefits for energy and tiredness, but the average effect on performance no clear. E no prove say every interruption help person recover or say every break cost the same to switch tasks. Albulescu et al., 2022
Sustained attention dey change over time too. Research on these changes no describe person as either fully focused or unable to work for one fixed period. The task itself and the result wey dem measure still matter. Esterman et al., 2013
Wetin you fit really change?
When the situation allow am, keep clear reminder of the next step; this agree with research on resuming task. The specific experiment evidence concern preparation around an interruption; e no guarantee say writing one note go remove every real-life cost of switching. Make the conclusion no strong pass wetin the evidence support. Trafton et al., 2003 Altmann et al., 2002
If you dey observe yourself, separate time wey you spend away from task from time wey e take you to start again. Write down the kind of interruption, whether the first task never finish, and the result wey matter to you. If you no do this, you fit mistake long time gap as long brain recovery, even when you don finish other work. Mark et al., 2005 Leroy, 2009
Wetin switching game fit tell you?
One controlled switching task fit show the cost of changing rules. E no fit turn small difference from short laboratory-style task into minutes of workplace productivity wey person lose. Research on reliability warn too say make person no treat small score difference as fixed trait of one person. Hedge et al., 2017
The evidence support taking the situation around interruption seriously. E no support adding automatic 23-minute cost to every notification, conversation or planned pause, no matter wetin the person do next. Mark et al., 2005 Trafton et al., 2003
Try the free test wey connect to this one
Test for switching between tasks
Try the test for switching between tasks to experience how you dey alternate between rules. E measure how you perform for that task; e no measure how many minutes you lose after work interruption. Remember the difference when you compare the game with your day.
Common questions
The 23-minute number na fact wey apply to everybody?
No. Returning to task, starting am again and recovering one particular performance measure na different results. Mark et al., 2005 Trafton et al., 2003
Preparation before interruption fit help?
One controlled study find say people resume quicker after an eight-second warning wey give dem chance to prepare. Nobody guarantee how much this go help for real life. Trafton et al., 2003
Planned breaks dey bad for focus?
Evidence about microbreaks find small benefits for tiredness and energy, but the general benefit to performance no certain. Make we no treat planned breaks as the same thing as every interruption. Albulescu et al., 2022
