Recent research suggests that different color temperatures of indoor lighting can modulate cognitive performance and alertness. A team of cognitive neuroscientists wants to use the laboratory experimental method to investigate whether exposure to blue-enriched white light (6500 K) leads to better spatial working memory performance compared to standard warm-white light (2700 K). Performance is to be measured using a standardized 3D block-reconstruction task.
Explain how you would conduct a study using the laboratory experimental method to investigate whether there is a difference in spatial working memory performance under blue-enriched white light compared to warm-white light. Justify your decisions as part of your explanation.
