Introduction to Life: Foundations of Being a Person

Week 5 — Touching Grass 101

Memory and attention performance improved by roughly 20% after an hour interacting with nature.

Today’s scope

“Go outside” has an actual, measured mechanism behind it.

Attention restoration only — general physical-health benefits are out of scope.

What’s ahead

  • What happens to attention outdoors
  • Why cities are worse for this specifically
  • Running a restorative session, step by step

Definitions

  • Outdoors (noun) — the region beyond a building’s exterior walls, accessible via a door.
  • Sunlight (noun) — direct illumination from the sun, typically encountered before 2pm.
  • Fresh air (noun) — air that has not previously circulated through a shared bedroom for several consecutive days.

Key point 1 — Attention restoration, defined plainly

Berman, M. G., Jonides, J., & Kaplan, S. (2008). The cognitive benefits of interacting with nature. Psychological Science, 19(12), 1207–1212.

Walking in a natural setting — or even viewing pictures of nature — improved directed-attention task performance versus a busy urban walk.

Check-in: Would a walk through a busy street give you the same benefit as a walk through a park, according to this study?

Key point 2 — Why this isn’t about “fresh air”

Same exercise. Same pace. Same outdoor air.

The attentional effect still differs — it’s the setting doing the work, not the oxygen.

Check-in: If it's not the air or the exercise, what is actually different between the two walks?

Key point 3 — Running a restorative session, step by step

At least fifteen minutes, in a setting with visible plants or water — a park, a garden, a tree-lined street all qualify.

A car park or a bare footpath doesn’t.

Phone away, not just silenced: checking it resets the attention effect the same way switching back to a screen does.

Check-in: Would fifteen minutes in a car park qualify as a restorative session, by this definition?

In-lecture activity

Look out the nearest window.

No window? Close your eyes and picture the last outdoor space you were in.

A few seconds of silence before continuing.

Conclusion

The outdoors measurably restores attention, not just mood.

Reframes “get out more” as a specific, useful action — and a fifteen-minute, phone-away version of it you can actually run.

Coming up: this week’s lab (the outdoor field observation).

This week’s reflection

Due 12:00 Tuesday of week 6:

Measure your own 400-metre radius this week, roughly, and name the single errand or event that would have taken you furthest outside it.
