Cette étude a cherché à savoir si les plantes d’intérieur étaient aussi efficaces qu’une méditation guidée pour permettre la récupération psychologique après la fatigue induite par la tâche de vigilance abrégée. Soixante étudiants ont été assignés au hasard à une plante d’intérieur, à une méditation guidée ou à une condition de pause de contrôle. Les processus psychologiques ayant le plus besoin de récupération ont été identifiés comme étant la restauration cognitive et affective. Des mesures de l’affect, du stress et de la mémoire de travail ont été prises avant et après la tâche de vigilance, puis après une intervention de repos.

This study investigated whether indoor plants were as effective as a guided meditation for enabling psychological recovery after fatigue induced by the abbreviated vigilance task. Sixty students were randomly assigned to an indoor plant, guided meditation, or control rest-break condition. The psychological processes most in need of recovery were identified as cognitive and affective restoration. Measures of affect, stress, and working memory were taken before and after the vigilance task, and again after a rest intervention. The vigilance task-induced fatigue as shown by a significant vigilance decrement and also significantly lowered positive affect and cognitive engagement, and significantly increased distress across all three conditions. After exposure to the break interventions, distress significantly decreased for participants in the indoor plant break condition while distress significantly decreased and engagement significantly increased in the guided meditation break condition. Indoor plants and guided meditation had a small, but significant positive impact on affective restoration and no significant impact on cognitive restoration. Practitioner summary: Indoor plants are a cost-effective green ergonomics intervention in offices. This study found that a rest break with indoor plants was as effective as a rest break with guided meditation for affective restoration after fatigue from a vigilance task.AbbreviationsARTattention restoration theoryLCDliquid crystal displayPANASpositive and negative affect scheduleDSSQS: dundee stress state questionnaire – short versionBDSbackward digit spanANOVAanalysis of varianceCIconfidence intervalMmean
