Why paying attention to a wait can make it feel shorter for one person and longer for another — and why the direction depends on the same forewarning distinction Week 1 introduced.
Two entries from the same log, both waits of roughly the same clock length, can carry judged durations that don’t agree even a little. The easy explanation — “the short one felt short because I was busy” — is exactly the kind of move Week 1 warned you against making from a single pair: it’s a candidate, not a conclusion, and this week is about what it takes to treat it as more than that.
A field you already have#
You didn’t need a new log field for this. Every entry from Week 1 already records what you were attending to during the wait, and what information you had about how long it would be. This week just asks a new question of those same two fields: does how much attention a wait demanded, and whether you were actively monitoring it, help explain why one entry’s judged duration sat close to its clock duration and another’s didn’t.
Occupied and unoccupied, carefully#
The practitioner literature on service queues has a standard proposition, usually credited to Maister: unoccupied time feels longer than occupied time of the same length. It’s a useful rule of thumb for anyone designing a waiting room or a queue — give people something to do or look at, and the wait reads as shorter. Treat it as exactly that: a working heuristic drawn from observing real queues, not a settled finding from controlled research, and not a law that holds the same way in every circumstance.
What actually happens under load#
The controlled research tells a more specific story. Block, Hancock and Zakay’s meta-analytic review pooled 117 experiments that varied how attentionally or cognitively demanding a wait’s task was — what they call cognitive load — and asked what that load did to duration judgements in each of the two paradigms Week 1 established (Block, Hancock & Zakay, 2010). The direction of the effect depended on which paradigm was in play: under higher demand, prospective judgements came out shorter relative to the wait’s actual length, while retrospective judgements of an equally demanding wait came out longer relative to it. The same increase in demand pushed the two paradigms’ estimates in opposite directions, not the same one.
That’s broadly consistent with the two accounts Week 1 introduced. One attentional account of the prospective side holds that someone forewarned and occupied by a demanding task has less attention left over to track time passing, so whatever internal sense of duration they’re building runs behind — judged shorter. One memory-based account of the retrospective side holds that a more demanding interval leaves more contextual information to be retrieved when the duration is judged afterwards, which can contribute to a longer retrospective estimate. Both are theoretical interpretations of the finding, not findings in their own right; neither claims occupation shortens a wait outright, both make its effect depend on which paradigm the judgement came from, and the size of either effect varies across the pooled studies rather than landing on one number.
Reading Maister against the finding#
Maister’s proposition is a useful practitioner starting point, but it does not capture the full pattern found in controlled research. “Occupied time feels shorter” tracks the prospective side of the finding reasonably well — someone forewarned and kept busy plausibly does judge the wait as shorter. It doesn’t obviously extend to a retrospective wait, where being occupied can make the same interval loom larger once you look back on it, not smaller. A rule of thumb built by watching queues from the outside has no reason to have separated these two cases; the research asking people to make the judgement themselves does.
Why this matters#
This is the first mechanism the course puts a name to: attention and occupation, as one candidate explanation for why judged duration and clock duration come apart. It won’t be the last — expectation and information are next — but it’s the one that shows most clearly why a mechanism’s effect has to be read against the paradigm it’s operating in, not assumed to point the same way regardless. That’s still the course’s one thesis at work: waiting is an experience, not merely a duration, and “how occupied was I” is one of several things that experience depends on.
What you’re doing this week#
The session takes this back to your own log: rereading entries you already have, asking whether attention plausibly explains a difference between two of them, and adding one more entry from an ordinary wait that naturally differs in what occupied your attention. One mechanism, checked against a handful of personal entries, still can’t prove anything — it can only tell you whether attention is consistent with what you’ve already recorded, which is exactly what Week 3 will ask you to check again once expectation is on the table too.
