Key evidence an nummers
| Outcome | Whit's measured | Why it's different |
|---|---|---|
| Time afore gettin back tae a task | Includes wark an choices in atween | No continuous time spent no bein able tae focus |
| Resumption lag | Time tae stert again efter an interruption ends | Depends on the task an mindin the goals |
| Attention residue | Carry-ower fae a bygan task | Can affect performance athoot a fixed clock |
The field study looks at how wark is organised, no at a universal physiological reset. A body can wark on ither tasks afore gettin back tae ane that wis interrupted. Takkin that elapsed time tae mean bein unable tae concentrate the hale time changes whit wis measured. Mark et al., 2005
Whit does laboratory resumption research shaw?
Trafton an colleagues compared an immediate interruption wi a warnin condition that gied fowk aicht seconds afore the interruption stertit. Participants wi a warnin got mair prepared an stertit again quicker. This backs the role o thinkin ahead an mindin the original goal, no ane unvaryin recovery time. Trafton et al., 2003
Altmann an Trafton's model describes hou goal activation an retrieval can influence stertin again. Leroy's experiments look at attention residue whan fowk switch awa fae unfinished wark. Thir accounts concern related but distinct processes, sae their measures shouldnae be pitten thegither intae ae universal meenit estimate. Altmann et al., 2002 Leroy, 2009
Can fowk mak up for interruptions?
In Mark an colleagues' experiment, interrupted participants finished tasks quicker athoot a difference in quality, but reported mair stress, frustration, time pressure an effort. Quicker completion therefore didnae prove that interruptions were harmless. This is anither example o why ae productivity measure isnae eneuch. Mark et al., 2008
Whit affects it?
Are aw breaks the same as interruptions?
Naw. A planned rest break an an unexpected demand tae dae a different task can hae different purposes an demands. The microbreak meta-analysis finds sma benefits for vigor an fatigue, wi an uncertain average effect on performance. It disnae prove that ilka interruption is restorative or that ilka break brings the same cost o switchin. Albulescu et al., 2022
Sustained attention fluctuates ower time an aw. Research on thir fluctuations disnae describe a body as either fully focused or aye unavailable for ae fixed period. The actual task an the performance outcome still matter. Esterman et al., 2013
Whit can ye realistically change?
Whan the situation lets ye, keepin a clear cue for the neist step fits wi the resumption research. The specific experimental evidence concerns gettin prepared afore an interruption; it disnae guarantee that writin ae note gets rid o aw real-warl switchin costs. The inference should stay modest. Trafton et al., 2003 Altmann et al., 2002
For yer ain observations, tell the difference atween time awa fae a task an time needed tae stert it again. Note the kind o interruption, whether the original task wis unfinished, an whit outcome ye care aboot. Itherwise, a lang gap can be mistak for a lang cognitive recovery, even whan ither wark got done. Mark et al., 2005 Leroy, 2009
Whit can a switchin gemme tell ye?
A controlled switchin task can shaw the cost o changin rules. It cannae turn a brief laboratory-style difference intae meenits o lost workplace productivity. Reliability research warns an aw against treatin a short difference score as a fixed personal trait. Hedge et al., 2017
The evidence backs takkin the context o an interruption seriously. It disnae back applyin an automatic 23-meenit cost tae ilka notification, blether or planned pause, nae matter whit the body actually daes neist. Mark et al., 2005 Trafton et al., 2003
Gie the related free test a try
Task switchin test
Try the task switchin test tae experience swappin atween rules. It measures yer ain performance on the task, no hou mony meenits ye lose efter an interruption at wark. Mind that difference whan ye compare the gemme wi yer day.
Common questions
Is the 23-meenit figure aye true?
Naw. Gettin back tae a task, stertin it again an recoverin a particular performance measure are different outcomes. Mark et al., 2005 Trafton et al., 2003
Can gettin ready afore an interruption help?
A controlled study fand quicker resumption efter an aicht-seicont warnin that let fowk prepare. The size o a real-warl benefit isnae guaranteed. Trafton et al., 2003
Are planned breaks bad for focus?
The microbreak evidence finds sma benefits for fatigue an vigor, wi less certain benefits for performance overall. Planned breaks shouldnae be equated wi ilka interruption. Albulescu et al., 2022
