Abstract

Popular articles and manufacturers' literature assert that full-spectrum fluorescent lighting improves cognitive performance, vision, and mood. Previous experimental investigations have failed to demonstrate these effects. This paper reports an attempt to replicate earlier work concerning the effects of information sets about lighting on performance and mood. In this 2 (lamp type) × 4 (information sets) × 2 (gender) factorial experiment, 104 male and 104 female participants were led to expect good, poor or indifferent outcomes of working under full-spectrum or cool-white fluorescent lighting, or they were not given any information. There were no effects of lamp type or information set on performance or mood. The results are discussed in relation to other evidence that cognitive processes mediate lighting-behaviour relationships.
