Air high quality within the workplace could have an effect on our stage of creativity at work, scientists at Nanyang Technological College, Singapore (NTU Singapore) have discovered.
Working with the worldwide air filter producer Camfil on a shared analysis mission, the NTU Singapore scientists present in a examine that prime ranges of unstable natural compounds – gases launched from merchandise reminiscent of detergents, pesticides, perfumes, aerosol sprays and paint – affected the examine contributors’ creativity after they have been requested to construct 3D fashions with LEGO bricks.
Utilizing a statistical evaluation, the NTU workforce estimated that lowering complete unstable natural compounds (TVOC) by 72 per cent may enhance a scholar’s artistic potential by 12 per cent.
TVOC is an indicator that refers back to the quantity of unstable natural compounds within the air. Indoor VOCs are emitted from inside ornament sources reminiscent of paints and carpets and family merchandise reminiscent of detergents and air fresheners.
This examine, carried out on the NTU Good Campus, is a part of a partnership between the College and Camfil to research the influence of indoor air high quality on the cognitive efficiency of adults, take a look at numerous air filter applied sciences in tropical climate situations, and ship modern clear air options mixed with optimised power effectivity.
The findings detailed within the examine, revealed in Scientific Experiences in September, make clear the significance of indoor air high quality on our artistic cognition, mentioned the analysis workforce led by Assistant Professor Ng Bing Feng and Affiliate Professor Wan Man Pun, Cluster Administrators for Good & Sustainable Constructing Applied sciences on the Vitality Analysis Institute @ NTU (ERI@N).
Asst Prof Ng mentioned: “Whereas most individuals would appropriately affiliate indoor air high quality with results on the lungs, particularly since we simply emerged from a pandemic, our examine reveals that it may additionally have an effect on the thoughts and inventive cognition, or the flexibility to make use of information in an unconventional manner. Our findings recommend that comparatively low TVOC ranges, even when effectively throughout the accepted threshold, may influence a person’s artistic potential.”
This might have severe penalties for industries that depend on creativity for the majority of their work. As an example, artists usually use paints and thinners that launch excessive ranges of unstable natural compounds and will not know they want satisfactory air flow to clear them from their office. The findings additionally level to how making minor changes within the workplace, reminiscent of lowering using aroma diffusers or making certain satisfactory air flow, may positively influence workers and their productiveness.”

The examine additionally aligns with the Well being & Society and Mind & Studying analysis clusters underneath the analysis pillar of NTU 2025, the College’s five-year strategic plan.
The opposite scientists on the analysis workforce have been NTU PhD graduate Dr Shmitha Arikrishnan, former NTU senior analysis fellow Dr Adam Charles Robert, who’s at present a postdoctoral researcher at Singapore-ETH Centre, and NTU graduate Lau Wee Siang.
Assessing creativity by LEGO 3D fashions
To quantifiably assess artistic potential on this examine, the NTU workforce developed the Critical Brick Play methodology, which is essentially tailored from the LEGO Critical Play framework. This instrument entails expressing ideas and concepts utilizing 3D fashions constructed with LEGO bricks.
A typical LEGO Critical Play session entails a facilitator who introduces a problem, to which contributors reply by constructing a mannequin utilizing LEGO bricks. Contributors then focus on their fashions and replicate on the constructing course of, prompted by the facilitator.
Within the Critical Brick Play methodology designed by the NTU workforce, contributors don’t focus on their fashions and share their reflections in a bunch. As an alternative, they supply written descriptions of their LEGO fashions. These written descriptions and LEGO fashions are then scored by a panel of judges for creativity.
Asst Prof Ng defined: “Whereas the LEGO Critical Play framework has been utilized in numerous settings to unleash artistic considering and has even been used to assist dementia sufferers, it doesn’t have a quantitative evaluation part and can’t systematically assess creativity. This is the reason we added a part to attain contributors on their creativity.”
The scoring tips for the contributors’ LEGO fashions have been developed primarily based on the Artistic Product Evaluation Matrix mannequin, which is used to grade creativity and has been validated in earlier research, he added.
The NTU researchers examined the scoring tips to measure the diploma of consistency among the many completely different judges after they independently assessed the LEGO fashions, and concluded that the scoring tips supplied have been dependable.
The researchers additionally examined the Critical Brick Play methodology’s capacity to measure what it was designed for by statistical analyses and located that the strategy was capable of cowl the important thing elements of the Various Makes use of Process, a well known instrument that assesses creativity. Particularly, it assesses divergent considering, a thought course of used to generate artistic concepts by exploring many potential options.
The researchers mentioned that the Critical Brick Play methodology additional assesses one other thought course of known as convergent considering, which focuses on arising with a single, well-established reply to an issue.
“Divergent and convergent considering are regarded as the central parts of creativity, however most present instruments are designed round divergent considering. Our Critical Brick Play methodology provides worth by additionally protecting the facet of convergent considering,” mentioned Asst Prof Ng.
How the examine was completed
Over six weeks, the researchers gathered knowledge from a pattern dimension of 87 undergraduate and postgraduate college students in a managed surroundings simulating an indoor workspace. Each week throughout three 40-minute classes, the examine contributors learn a abstract of a world challenge – reminiscent of local weather change, psychological well being, and poverty – after which supplied an answer by constructing a 3D mannequin utilizing LEGO bricks. The contributors have been then requested to provide a written description and clarification for his or her fashions.
In every session, researchers different the air high quality of the workspace utilizing completely different combos of air filters contributed by Camfil. This different the extent of pollution within the air, together with carbon dioxide, PM2.5 (air pollution lower than 2.5 micrometres in diameter), and complete unstable natural compounds (TVOC).
The contributors’ LEGO fashions and descriptions have been then graded by seven randomly chosen adults, who have been skilled to familiarise themselves with the scoring tips primarily based on:
- Originality: whether or not the answer is common or uncommon,
- Fluency: the extent of elaboration within the description of the answer, and
- Construct: how refined, advanced, or aesthetic the answer is.
Hyperlink between TVOC ranges and creativity
The NTU workforce’s statistical evaluation of the contributors’ common scores and indoor air high quality knowledge gathered from 18 classes revealed that contributors tended to show in artistic options with decrease scores – an indicator of decrease artistic potential – when the workspace had greater TVOC ranges.
Utilizing a statistical mannequin, the workforce calculated that lowering TVOC from an appropriate threshold of 1,000 components per billion to 281 components per billion – or a 72 per cent discount in TVOC ranges – led to a 12 per cent improve in artistic potential within the examine cohort.
Much less vital relationships have been discovered between PM2.5 and creativity in addition to carbon dioxide ranges and creativity.
Asst Prof Ng mentioned: “The outcomes from this examine point out that creativity ranges could be linked to the focus of pollution in a room. Bettering the air high quality could possibly be a cost-effective answer to enhance occupants’ creativity.”
Having uncovered a hyperlink between TVOC ranges and creativity, the analysis workforce is now learning how TVOC and different indoor air pollution have an effect on cognitive processes by measuring contributors’ mind exercise.
