From the article: "In each experiment, 12 subjects (280 total; ages 21.7 ± 1.5 year)" This would imply that each variable group was composed of 12 participants

From the article: "In each experiment, 12 subjects (280 total; ages 21.7 ± 1.5 year)"
This would imply that each variable group was composed of 12 participants but overall there were 280 participants.
- rosser 12y agoFrom the "Experiment Design" section of the paper, emphasis added: "The subjects were randomly divided into two groups. On the first day of the experiments, six subjects were sent to a forest site, and the other six subjects to a city site. On the second day, the subjects were sent to the other type of site as a cross-check." To me, that suggests 12 total subjects, and 280 "trials".
- alexjeffrey 12y agoI believe the implication is that this is the procedure on a per-group basis (considering each group has 12 members).
