Yeah, absolutely.
There had been research done.
I wasn't the first person to look to see if interacting with nature had psychological benefit.
There had been other studies where they had people interact with more natural environments versus more urban environments, and people reported feeling better.
Maybe their mood improved or maybe they felt like their attention was better, but they didn't use any objective measures of performance.
So we did one of the first studies where we actually measured objectively people's changes in performance after interacting with these different environments.
And one of the ways that we measured people's objective performance was with a task called the backwards digit span task.
So that's a task where you would hear digits out loud at about one digit per second.
And you would need to repeat the digits back in backwards order.
So you might hear the digits 8, 3, 7, and then you need to repeat it back in backwards order.
So 7, 3, 8.
And we keep increasing the number of digits up to about nine digits.
At around five digits, the task is very challenging.
Yeah.
So what we did is we gave people this difficult backwards digit span task.
Then we had them go for a walk in a more natural environment or go for a walk in a more urban environment.
They came back to the laboratory after the walk and the walk was about 50, five, zero minutes.
They come back to the lab, they do this backwards digit span task again.
And then they come back to the lab a week later and they repeat the whole procedure again.
If they walked in the natural environment the first week, they walk in the urban environment the second week or vice versa.
