An environmental psychologist conducted a study to investigate the relationship between daily exposure to natural green spaces and subjective psychological recovery after work. She used a correlational design with a self-selected sample of 60 urban office workers who responded to an advertisement on a corporate intranet.

Each participant's green space exposure was measured by tracking their outdoor GPS location data (in minutes) over a two-week period. At the end of the two weeks, their subjective recovery levels were assessed using a standardized 20-item occupational wellbeing questionnaire, producing a score out of 80.
