The way that “hotspots” such as parks or nearby noisy highways influence the evaluation of other spaces, such as homes for sale, has been carefully studied.  Blaison, Gollwitzer, and Hess found that “Irrespective of intrinsic [inherent] neighborhood attractiveness, pleasantness ratings went up with increasing distance from negative hotspots [that noisy highway]. . . . negative hotspots are much more harmful to attractive neighborhoods than to unattractive ones. Indeed, the more distant locations of unattractive neighborhoods even ‘benefit’ from a contrast effect that makes these places look nicer in comparison to places that are located closer [to that negative hotspot]. . . . . [Neighborhood attractiveness] . . . influenced the evaluation of the hotspot itself. An urban park was seen as less attractive in a highly salient [noticeable] unattractive neighborhood than in an attractive one.”

Bedrosian and Nelson studied how being exposed to light at night influences wellbeing and mood.  They share that “Many systems are under circadian control, including sleep–wake behavior, hormone secretion, cellular function and gene expression. Circadian disruption by nighttime light perturbs those processes and is associated with increasing incidence of certain cancers, metabolic dysfunction and mood disorders. . . . Converging evidence suggests that circadian disruption alters the function of brain regions involved in emotion and mood regulation.”  Light at night seems to negatively affect mood throughout the day.  Ways to reduce circadian system disruption by artificial nighttime light mentioned by Bedrosian and Nelson include “‘Smart’ homes and ‘smart’ lighting fixtures [that] use precise LEDs to adjust the wavelength of light depending on the time of day. . . . New street light designs are being introduced to focus the light toward the street and avoid upward light leakage. And heavy black out curtains impermeable to light are being adopted for bedroom use.”

Krause and North researched how music-playlist preferences vary by time of year.  They report that “The literature concerning seasonal correlates of mood and behavior suggests that colder weather is associated with low activity and a reflective cognitive style, whereas warmer weather is associated with higher activity levels. Analyses of the season-based music-playlist preferences of 402 participants . . . demonstrate listener preferences for Arousing music for the warmer months, Serene music for spring, and Melancholy music for the cooler months.”  These findings can inform the design of seasonally used places/objects/services, generally.

Faraji-Rad and Pham wondered how uncertainty affects how people think.  They found that thinking about uncertainty/feeling uncertain increases “reliance on affective [emotional] inputs in judgments and decisions. . . . uncertainty [was] shown to amplify the effects of the pleasantness of a musical soundtrack, the attractiveness of a picture, the appeal of affective attributes, incidental mood states” on judgments/decisions made – for example, the effect of the picture on a television screen on evaluations of that television was influenced by whether the people assessing it were feeling uncertain or not. As the researchers state, thinking about uncertainty/feeling uncertain “increases the effect of momentary feelings on consumers’ decisions and product evaluations. . . . the priming of uncertainty (vs. certainty) increases the relative preference for options that are affectively superior over options that are functionally superior.” The researchers report that “states of uncertainty—that need not be related to the decisions that people face—influence the way people make decisions.”

Think that the ways that cultures discuss colors don’t change or that all cultures speak about the color spectrum in the same way?  Think again.  An article in the Journal of Vision, reports that an analysis of color terms used by modern Japanese speakers determined that they utilized  “the 11 basic color categories common to most modern industrialized cultures (red, green, blue, yellow, purple, pink, brown, orange, white, gray and black). . . . [as well as] mizu ("water")/light blue, hada ("skin tone")/peach, matcha ("ceremonial green tea")/yellow-green, oudo ("mud")/mustard, enji/maroon, yamabuki ("goldflower")/gold and cream. . . . Thirty years ago, a study of Japanese color categories . . . did not reveal mizu as a basic color category. . . . [and found] that kusa ("grass") was a very popular term for yellow-green . . . kusa has been largely replaced with matcha . . . . there is one tradition that has not changed over the past millennium: the mixed use of green and blue.”  A study of poems written prior to the 10th century indicates that historically “ao ("blue") was used to name both things that were clearly blue and also things that were clearly green; the same was true of midori ("green"). Even today, modern Japanese people refer to the color of the green traffic light, lush green leaves and green vegetables, as ao ("blue"). . . . in addition to distinct color terms for blue and green, modern Japanese has recently added a new intermediate color term "mizu" for lighter bluish and greenish samples.”

Sheldon and Donahue’s work confirms that the type of music listened to influences memories recalled.  The researchers found that “if you listen to happy or peaceful music, you recall positive memories, whereas if you listen to emotionally scary or sad music, you recall largely negative memories from your past.” The Sheldon/Donahue study is published in Memory and Cognition.   More details on the study conducted: “participants had 30 seconds to listen to 32 newly composed piano pieces not known to them. The pieces were grouped into four retrieval cues of music: happy (positive, high arousal), peaceful (positive, low arousal), scary (negative, high arousal) and sad (negative, low arousal). Participants had to recall events in which they were personally involved that were specific in place and time, and that lasted less than a day.”

Seeing images of nature in the labor/delivery room improves the experience of giving birth.  Aburas and her team report that “Incorporating design elements and strategies that calm and reduce negative emotions may create positive experiences for women in labor.”  When images of nature were present during the labor and delivery period, scores were higher on “the Quality of Care From the Patient’s Perspective (QPP) subscale. In addition, there was an increase in the QPP scores associated with the increase in Nature TV watching time, QPP mean of watching time (less than 1 hour) group . . . and QPP mean of watching time (more than 3 hours). . . . The mean score for the heart rate was lower in the experimental condition . . . than in the control one [no nature images] . . . . These findings support the study hypothesis which states that the nature images would influence the labor experience positively.”

DuBose and her research team explored how spatial design can influence healing.  They share that “there is a growing recognition that our healthcare system could do more by promoting overall wellness, and this requires expanding the focus to healing. . . . this review of the literature presents the existing evidence to identify how healthcare spaces can foster healing. The environmental variables found to directly affect or facilitate one or more dimension of healing were organized into six groups of variables—homelike environment, access to views and nature, light, noise control, barrier-free environment, and room layout. . . . Healing spaces. . . . support healing intention and foster healing relationships.”

Blaschke and her colleagues have learned that adding artificial plants to spaces can have desirable outcomes.  Their study was based in an oncology clinic waiting room in Australia and collected data from cancer patients, staff members, and people caring for the cancer patients.  The investigators found that  “Eighty-one percent . . . of respondents noticed the [artificial] green features when first entering the waiting room and 67% . . . noticed they were artificial. Eighty-one percent . . . indicated ‘like/like a lot’ when reporting their first reaction to the green features. Forty-eight percent . . . were positively affected and 23% . . . were very positively affected. Eighty-one percent . . . agreed/strongly agreed that ‘The greenery brightens the waiting room,’ 62% . . . agreed/strongly agreed that they ‘prefer living plants,’ and 76% . . . agreed/strongly agreed that ‘‘lifelike’ [artificial] plants are better than no plants.’. . . . Patients, staff, and carers mostly accepted artificial plants as an alternative design solution to real plants.” The artificial plants in place included “plant arrangements, hanging installations, two movable green walls, and one rock garden on wheels placed throughout the outpatients’ clinic waiting room.”

Research by Choi and her team indicates that a lot of walls in video conference centers and other locations should be painted warm colors.  As they detail, their data, collected in the US and South Korea, indicates that “an anonymous person against a warm color background (vs. neutral and cold color background) is perceived to be one with warmer personality.”  In addition, “nurses’ perception of warmth from a hospital’s ambient color affects their favorable judgment of the hospital and intention to take on an extra role.”
