One of the benefits of Green Spaces may be the restoration of attention and so the objective of this research is testing empirically whether exposure to a green environment improves attention in school children. For so doing, we first used a split-unit statistical design in each of four schools, then combined the primary results via meta-analysis. The Attention Network Test (ANT) was used to measure attention before and after exposure and a total of 167 seven-year-old students participated in the experiments. Overall, our experimental results do not support the hypothesis that students\u2019 exposure to activities in green vs. grey spaces affected their performance in ANT. This was so despite the fact that neither age nor gender biases have been detected and despite that our experiments have been proved to be sufficiently statistically powerful. It would be advisable to consider air pollution and noise. We also recommend that participants attend the experiment with mental exhaustion to maximize the ability to detect significant changes.<\/jats:p>","DOI":"10.3390\/ijerph18147484","type":"journal-article","created":{"date-parts":[[2021,7,13]],"date-time":"2021-07-13T22:25:31Z","timestamp":1626215131000},"page":"7484","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Is Brief Exposure to Green Space in School the Best Option to Improve Attention in Children?"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9142-0419","authenticated-orcid":false,"given":"Asier","family":"Anabitarte","sequence":"first","affiliation":[{"name":"Preventive Medicine and Public Health, University of the Basque Country (UPV\/EHU), Barrio Sarriena s\/n, 48490 Leioa, Spain"},{"name":"Biodonostia, Environmental Epidemiology and Child Development Group, Paseo Doctor Begiristain s\/n, 20014 Donostia-San Sebastian, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6550-1584","authenticated-orcid":false,"given":"Gonzalo","family":"Garc\u00eda-Baquero","sequence":"additional","affiliation":[{"name":"Biodonostia, Environmental Epidemiology and Child Development Group, Paseo Doctor Begiristain s\/n, 20014 Donostia-San Sebastian, Spain"},{"name":"Consortium for Biomedical Research in Epidemiology and Public Health (CIBERESP), Instituto de Salud Carlos III, Av.
