Study Finds Intergenerational Art Projects Reduce Loneliness But Alter Brain Synchronization
Translated & summarized from Bizportal by baba
A six-week study involving strangers creating art together found that loneliness decreased and social connection increased in all participants. However, brain synchronization patterns differed, with same-generation pairs showing increased synchronization and intergenerational pairs showing decreased synchronization, suggesting different relationship dynamics.

- Collaborative art sessions reduced loneliness and increased social connection for strangers.
- Intergenerational pairs showed decreased brain synchronization, unlike same-generation pairs.
- Brain synchronization may not be a direct indicator of relationship quality.
- The study used hyperscanning to measure brain activity during creative tasks.
- Loneliness reduction occurred quickly with simple, creative, intergenerational activities.
A recent study published in PLOS Biology on August 20, 2026, explored the effects of collaborative art-making between strangers, particularly focusing on intergenerational pairings. Researchers from ETH Zurich, the University of Montreal, and Mila Institute for AI in Quebec monitored 61 pairs of strangers, including 31 intergenerational pairs (ages 18-35 with individuals 69+) and 30 same-generation young adult pairs. Participants engaged in hour-long weekly sessions for six weeks, involving questionnaires on loneliness and social connection, followed by drawing tasks and puzzles.
The study found that both groups experienced a significant reduction in loneliness and an increase in social connection, with loneliness decreasing by approximately 1% and social connection rising by about 4% per session. This suggests that even brief, creative interactions with unfamiliar individuals can positively impact feelings of isolation over a short period.
However, a surprising finding emerged regarding brain synchronization, measured using hyperscanning technology that tracks blood flow via sensor caps. While synchronization increased in same-generation pairs, it decreased in intergenerational pairs, particularly in the right temporoparietal junction, an area involved in understanding others. This occurred despite both groups reporting similar improvements in social well-being.
Researchers hypothesize that individuals with similar backgrounds may align their brains more closely over time, while those with different backgrounds learn to complement each other, resulting in decreased synchronization. This suggests that brain synchronization is not a simple measure of affection. The study also noted that synchronization increased during joint drawing compared to individual drawing in both groups.
The findings have implications for combating loneliness, which is linked to significant health risks, including increased mortality. In Israel, where a quarter of those aged 65 and over report frequent loneliness, such programs offer a practical, low-resource approach. The study cautions that decreased synchronization in intergenerational pairs does not signify a failed relationship, and further research is needed to fully understand the physiological measure.
