Engagement in the arts has shown promise as a nonpharmacological approach for mitigating age-related cognitive decline. In this study, we report on feasibility and acceptability of a remote and self-administered observational drawing intervention that deliberately engages cognition, including spatial reasoning, hand-eye coordination, and awareness of the present moment. Thirty-four participants aged 65-87 completed our randomized controlled trial. The training consisted of 10 online lessons and daily practice in which participants acquired drawing techniques that improved their drawing skills by >
0.5 SD (d = 1.27). Over 80% who completed the course rated it positively and found the online format accessible, although we observed considerable attrition (47%). Baseline drawing skills were related to mental transformation (r = 0.47), yet transfer to cognitive stills at post-test was limited. Intervention-related improvements emerged in mindfulness (d(net) = 0.81). Our study illustrates that drawing skills can be improved in older adulthood and highlights the potential of visual arts training in promoting cognition and wellbeing.
