Then came the moment that recovering addicts pray never happens: He began lurking the aisles of hobby stores, searching for ever more obscure historical models, then buying them and building them at the desk where he once graded papers. He also noticed side effects. “Building models helps my hand-eye coordination, and following instructions and reading specifications sharpens my mental powers,” he says.
“Scale modeling is an excellent hobby,” agrees Andrea M. Macari, PhD, assistant professor of psychology at Suffolk County Community College in Long Island, NY. “Not only does the activity provide much-needed leisure, which is beneficial in alleviating anxiety and depression, but it also enhances certain cognitive skills such as concentration, visual-motor skills, and executive functions [processes the brain uses to plan, organize, strategize, and pay attention to and remember details].” Macari explains that the skills used in scale modeling are the same ones that often decline with age. “So by practicing scale modeling, your actions are mitigating any decline of those skills,” she adds.
Our Brains Love the Work. According to Professor Kelly G. Lambert of Randolph-Macon College in Ashland, VA, the brain is programmed to derive pleasure and satisfaction when efforts produce something “tangible, visible, and—this is extremely important—meaningful in gaining the resources necessary for survival.” To find a correlation between depression and physical efforts, she took two groups of rats and trained one group to dig for treats (the “worker rats”) and the other group to expect the treats in a lump sum, despite the effort they exerted (the “trust fund rats”). Next, she placed a treat inside a clear plastic ball, which couldn’t be opened no matter how hard the rat tried. Lambert found that the worker rats spent 60 percent more time trying to reach the treat than the trust fund rats did. The moral of the story: The workers were more confident they would succeed than the trust fund rats. And there’s more.
