Thygesen and colleagues link greater access to green space as a child to lower levels of Attention-Deficit Hyperactivity Disorder (ADHD). They report that when they reviewed data collected in Denmark for “individuals, who were born in Denmark between 1992 and 2007 . . . and followed for a diagnosis of ADHD from age 5, during the period 1997–2016. . . . Individuals living in areas defined by sparse green vegetation . . . had an increased risk of developing ADHD, compared with individuals living in areas within the highest [levels of green space]. . . .
Ozkul, Bilgili, and Koc studied how the color of light used in a restaurant influences diner experience. The researchers found when “five experiments were conducted in five ambient lighted in different colors. . . . the perception of service quality and the level of satisfaction were higher in red and yellow-lighted ambient than those in blue and green-lighted ambient.” Some technical details: “Yellow, blue, red, and green lights were obtained by covering the surface of white bulbs with colored gelatin. .
Tian, Chen, and Hu looked at appropriate levels of circadian stimulus (CS) by age. They determined that “the effect of the CS increased with CCT from 4000 K to 8000 K at the same age as a general trend; however, the CCT of 2700 K shows a higher circadian impact compared to that of 4000 K for the same age groups. . . . In order to provide sufficient CS, the minimum corneal illuminance for children and elderly is 250 lx and 380 lx, respectively, when the CCT of the light source was 2700 K.

Pontes and Williams found that seeing the color red influences gambling behavior. They report that “In general, people make more risk averse choices, gambling less and less often when primed with [shown] the color red over other colors. . . . when participants feel lucky or are from Asian Chinese backgrounds the effect is reversed and they take more risks when primed with the color red.”
Radicchi lead a team probing the psychological implications of urban soundscapes. The group found that “At an international level it is recognised that urban noise has serious and negative public health impacts. . . . Urban designers and planners. . . . need an awareness of the immaterial cultural heritage of place – cultural events, festivals, sound marks and oral traditions, when dealing with the protection and renewal of the historical city. . . .
Parsons reviews current research on thermal comfort; material that can be usefully applied in a variety of environments, from offices to public spaces, indoors and outside. This text is useful to practitioners, from architects to ergonomists, and includes a model linking thermal conditions and human performance.
