Summary
This study investigates whether brief exposure to virtual nature imagery influences attention restoration, specifically examining the amplitude of the error-related negativity (ERN) as a neural marker. The research is motivated by Attention Restoration Theory (ART), which posits that natural environments facilitate cognitive recovery by engaging effortless, bottom-up attention, whereas urban environments demand sustained, top-down attention leading to fatigue. While previous studies using real-world nature exposure have demonstrated increased ERN amplitude—a sign of enhanced executive function and error monitoring—findings regarding nature imagery remain inconsistent. This study aims to resolve these discrepancies by using electroencephalography (EEG) to determine if 2-D nature imagery elicits similar attention-dependent neural responses as real-world nature. The researchers employed a repeated-measures randomized control design with 60 participants. Each participant completed three testing sessions over a three-week period. In Sessions 1 and 3, participants viewed a neutral stimulus (a concrete wall) for 10 minutes before completing the Eriksen Flanker Task. In Session 2, participants were randomly assigned to view either nature or urban imagery for 10 minutes before performing the same task. EEG data were recorded during the Flanker Task to quantify ERN amplitude, which serves as a specific neural signature of error-monitoring processes and available attentional resources. The study controlled for physiological confounds such as sleep, caffeine, and alcohol intake. The results showed no significant differences in ERN amplitude across the three sessions or between the nature and urban imagery conditions in Session 2. Consequently, the hypothesis that nature imagery would significantly increase ERN amplitude, reflecting restored attentional resources, was not supported. The data indicated that brief exposure to the 2-D nature imagery used in this protocol did not produce the same neural changes associated with attention restoration observed in real-world nature immersion studies. These findings suggest that virtual nature imagery may not effectively replicate the cognitive benefits of real-world nature exposure, at least regarding the specific neural mechanisms measured by the ERN. The study highlights a critical distinction between real-world immersion and imagery-based interventions, implying that the restorative effects of nature may depend on factors absent in 2-D visual stimuli, such as multisensory engagement or physical presence. This contributes to the broader field by clarifying methodological limitations in nature-health research and suggesting that neurophysiological measures like the ERN can detect subtle differences that behavioral tasks might miss, ultimately indicating that real-world nature may be necessary for robust attention restoration.
