Beleuchtung, Motivation & Ermüdung
Die meisten Leute in industrialisierten Ländern verbringen einen grossen Teil ihrer Zeit drinnen und sind künstlichem Licht ausgesetzt. Deshalb ist es wichtig, physiologische und psychologische Wirkungen von Licht zu untersuchen, vor allem im derzeitigen Aufkommen von LEDs. Wir sind daran interessiert, wie Umgebungslicht die Motivation und spezifischer die mentale Anstrengung beeinflusst, und ob Licht den Motivationsdefiziten aufgrund von Ermüdung (mentale Ermüdung oder Ermüdung durch Schlafentzug) entgegenwirken kann. Wir testen die Wirkung von verschiedenen Lichtparametern, wie spektrale Eigenschaften und Lichtstärke. Wir nutzen Methoden aus der kognitiven Psychologie, der kardiovaskulären Physiologie und den Neurowissenschaften.
