Self-regulation
Do tidy or messy spaces help self-control and creativity?

A tidy room helped only low-self-control students persist longer at holding their breath, while a messy scene boosted creativity only for high-self-control students.
Study at a glance
- Design
- Human experiment — Two 2 (orderly vs disorderly environment, randomised) x 2 (high vs low trait self-control, median split) between-subjects experiments: a real tidy/messy room with a breath-holding task, then tidy/messy desk pictures with the Alternative Uses Test
- N
- N=274 · Separate samples: 152 analysed in Experiment 1 (room manipulation, breath-holding) and 122 analysed in Experiment 2 (picture priming, AUT)
- Population
- Chinese college students (mostly women) pre-screened on the Brief Self-Control Scale
- Outcome
- Experiment 1: change in breath-holding time from before to after exposure; Experiment 2: rated creativity of uses for a tire (average score, number of highly creative ideas, top-2 score)

Key findings
In Experiment 1, the tidy room produced more improvement in breath-holding overall, but the order-by-trait interaction was only marginal; the tidy-room advantage was clear for low-self-control students and absent for high-self-control students. In Experiment 2, the messy picture raised average creativity and top-2 creativity for high-self-control students, with no effect for low-self-control students, and no overall main effect of messiness. Mood and everyday tidiness habits did not differ across conditions.
Methodology
Students first completed a trait self-control questionnaire and were split at the median into high and low groups. In Experiment 1, they held their breath twice, waited a minute in either a neatly arranged or a cluttered room, and held their breath twice more; improvement in holding time indexed state self-control. In Experiment 2, a new sample looked at and described a picture of a tidy or messy desk, then listed creative uses for a tire, which blind raters scored for creativity.
Limitations
The key moderation in Experiment 1 was only marginally significant and the effects were small, and splitting a continuous trait at the median discards information and inflates the risk of spurious subgroup effects. The two experiments used different manipulations (a real room versus a picture) and different outcomes, so they cannot be directly compared, and the authors acknowledge limited sample sizes and reliance on self-report for trait self-control. The proposed mechanism, 'available self-control resources', was not measured directly, and it rests on the resource (ego-depletion) model, which is itself debated.
