A new experiment has shown that exposure to nature reduces violent behavior among prison inmates.
Inmates in maximum security prisons who watched nature videos showed reduced levels of aggression and were less likely to be disciplined than those in similar cellblocks, according to research presented at the American Psychological Association’s 2016 Annual Convention.
“We need nature for our physical and psychological well-being,” said clinical psychotherapist Patricia H. Hasbach, Ph.D. “Although direct contact with real nature is most effective, studies have shown that even indirect nature exposure can provide temporary relief from psychological stress in daily life.”
For the study, Hasbach and her colleagues studied a cellblock at The Snake River Correctional Institution in Oregon that housed 48 inmates. Half were provided nature videos to view during their scheduled indoor recreation time (three to four times per week over the course of a year). Content included images of diverse biomes (e.g., ocean, forest, rivers), aquarium scenes, a fireplace with burning logs, Earth viewed from space, and cloud fly-throughs.
The other prisoners were not offered the chance to view the videos.
“Inmate surveys and case study interviews with inmates suggested that negative emotions and behaviors such as aggression, distress, irritability, and nervousness were reduced following the viewing of videos and lasted for several hours post-viewing,” said Hasbach.
Prison staff also reported through case study interviews and written surveys that viewing the videos appeared to be a positive way to reduce violent behavior.
Over the course of the year studied, prisoners who viewed the videos had fewer disciplinary referrals than those who did not.
In fact, the researcher reports that the intervention has been considered so successful that it is now being used in other areas of the prison. Prison staff also use the videos as a targeted intervention when they see warning signs that an inmate may be about to act out.
“We found that inmates who watched the nature videos committed 26 percent fewer violent infractions,” said Hasbach. “This is equivalent to 13 fewer violent incidents over the year, a substantial reduction in real world conditions, since nearly all such events result in injuries to inmates or officers.”
