Attention Restoration Theory proposes that natural environments help restore depleted attentional resources, while urban settings further deplete attention. An experiment found that backpackers who spent 4 days hiking without technology performed better on a creative problem-solving test than those who had not embarked. The authors conducted an indoor experiment using nature and urban videos. Initial results matching outdoor studies found a 12% increase in nature scores and 5% urban increase. However, doubling video time reversed the effect, favoring urban scores. Moving forward, the authors feel outdoor experiments better capture immersion's powerful influence. Indoor studies may benefit from direct rather than indirect attention measures. Future research should use maximally restorative stimulus, like mystery-evoking
