Some research suggests that biophilic design elements in workspaces can enhance cognitive performance. To investigate this further, an environmental psychologist conducts a correlational study to examine the relationship between the number of living houseplants a remote worker has in their home office and their self-reported daily work productivity scores.
Suggest one open question that could be used in a follow-up questionnaire to provide additional qualitative data about how the presence of houseplants affects the participants' focus or feelings during their working hours.
