Blue-light background impairs visual exogenous attention shift

Cognitive function and memory: The paper explores how blue light affects cognitive processing, specifically visual-spatial attention, and finds that it can decrease the speed of exogenous attention shifts.

Alertness and performance: The paper discusses how blue light can affect alertness and cognitive performance, specifically in the context of visual-spatial attention.

Lighting Design Considerations: The paper's findings on the effects of blue light on cognitive processing and attention shifts could have implications for lighting design, particularly in environments where attention and cognitive performance are critical.
