Cajochen and colleagues investigated the effects of using LEDs that mimic daylight on user experience. They “tested an LED lighting solution mimicking a daylight spectrum. . . . young males twice spent 49 hours in the laboratory under a conventional-LED and under a daylight-LED condition. . . .
Research conducted by Cohen and her colleagues indicates that smells influence our memory performance; which can support strategic scentscaping of environments. The investigators had participants complete “an olfactory Pavlovian category conditioning task in which trial-unique exemplars from one of two categories were partially reinforced with an aversive odor. Participants then returned 24 h later to complete a recognition memory test. We found better corrected recognition memory for the reinforced versus the unreinforced category of stimuli in both adults and adolescents.
Design and performance evaluated
Warmer better for women, cooler better for men
Candido, Chakraborty, and Tjondronegoro investigated how office design influences user perceptions of their performance, health, and comfort. The researchers found via a post-occupancy evaluation program (nearly 9,000 completed surveys) of offices in Australia that “For open-plan offices, the best-performing features for predicting perceived productivity were . . . amount of interruption, work area aesthetics, degree of adaptation of the work area, furnishing, overall amount of noise, cleanliness, and personal control over lighting.
Gharaveis, Hamilton, Shepley, Pati, and Rodiek studied how Emergency Department design influences teamwork, communication, and security; their findings are applicable in both healthcare and other contexts. The Gharaveis-lead team reports that “By providing high accessibility and visibility, the security issues can be minimized and teamwork and communication can be enhanced. . . . Transparency in the core of the ED would improve levels of teamwork and communication. . . . design should provide visual and acoustical privacy when needed by flexibility in design. . . .
