Attention Restoration Theory (ART) describes the phenomena where people's attention spans verifiably increase after spending some time in nature. This is the case for all of us; young and old. Ottosson and Grahn (2005) found people in an aged care facility who were exposed to nature for one hour a week had improved attention compared to the elderly people who remained indoors. In a completely different context, Kuo and Sullivan (2001) found young adult residents who had a view of nature had higher scores on attentional capacity and were also less likely to be aggressive, compared to people who lived in the inner city.
