Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Li and Sullivan found no correlation between attention and stress changes and proposed nature exposure acts directly on working memory rather than through a stress pathway. → Dianne A. Vella-Brodrick · Krystyna Gilowska 2022

q2 · i? · review · r3
The review reports this mediation analysis from Li and Sullivan's window-view experiment, which measured self-reported attention and stress via Visual Analogue Scale plus physiological stress (blood volume pulse, electrocardiography, skin conductance, body temperature) entered into regression models.
"Since the analysis revealed no correlation between attention and stress changes, Li and Sullivan (2016) proposed that nature exposure was likely to have a direct impact on working memory performance rather than through the effect of a stress pathway."
Discussion¶
Related Claims¶
- Nature interventions improve working memory in school children relative to control conditions, for both immersive and passive exposures — a broader claim this one bears on
- In secondary school students, breaks with green views or walks in larger green spaces improve attention performance — related
