VR Time Perception: What a Five-Minute Maze Study Found

A felt duration and a clock reading answer different questions

VR time perception research asks how a duration feels compared with the time a clock records. Those measurements can disagree without the clock changing speed. The distinction matters when a headline says players lost track of time: what did the experiment actually ask them to estimate?

Consider a hypothetical player asked to stop when five minutes seem to have passed. If the player stops after six real minutes, the produced interval exceeds the target. That is a different observation from voluntarily choosing a longer session, completing more objectives or remembering yesterday's session as short.

The 2021 experiment asked players to produce five minutes

Grayson Mullen and Nicolas Davidenko recruited 41 undergraduates; 39 remained after excluding two extreme outliers. Participants played a maze game in VR and on a conventional monitor, with display order counterbalanced. Without visible clocks, they indicated when five minutes felt complete. This was a 2021 study, revisited here rather than newly announced research.

The target was fixed, but actual playing time was measured. That design makes the stopping response the important event. Reading the task this way helps avoid an easy misinterpretation: the researchers did not simply run identical five-minute sessions and then ask everyone how long they remembered playing.

Read the first-block difference against the right comparison

In the first block, mean produced intervals were 327.4 seconds in VR and 254.8 seconds on the monitor: a 72.6-second difference. Its reported 95% confidence interval was 4.6–140.6 seconds.

The comparison group matters. Subtracting the five-minute target, 300 seconds, from the VR mean gives 27.4 seconds. Subtracting the monitor mean instead gives 72.6 seconds. Both calculations use the reported means, but they answer different questions. The larger number is the gap between conditions, not the amount by which the VR group exceeded five real minutes.

The second block prevents a simple universal headline

After participants switched displays, the pattern depended strongly on starting condition. The authors limited their remaining analyses to first-block responses and discussed anchoring and novelty as possible explanations for the order effect.

An illustrative comparison makes the concern clearer. Imagine estimating a duration, then immediately doing a similar task again. Your first attempt may become a reference for the second. That possibility does not explain every result automatically; it shows why a repeated comparison needs more interpretation than treating the two attempts as interchangeable fresh observations.

An explanation needs evidence beyond the observed difference

Reduced bodily awareness was proposed as a possible mechanism, not established by a direct test of that mechanism in this experiment.

Keep two questions apart when reading the result: did the measured responses differ, and why might they differ? Evidence for the first does not settle the second. Calling the finding proof that immersion always changes an internal clock would add a general mechanism that the comparison cannot establish. A useful explanation should identify what evidence could distinguish it from alternatives.

Keep the task and sample attached to the finding

The analyzed participants were 18–26-year-old undergraduates. The study used one maze-game context, a five-minute target and a periodic reminder of the timing task.

A brief laboratory comparison therefore does not supply a conversion rule for every headset, game or long evening of play. When reading another time-perception claim, identify the target interval, the response method, the comparison condition and whether order changed the result. Those details preserve the interesting finding while leaving its reach open to further research. The university report linked below describes this same study, not an independent replication.
