Peeters, Smolders, and de Kort report on variations in lighting experiences among people working in the same office. The researchers report that when they “tracked office workers’ personal exposure during two three-week field intervention studies, one in winter, one in late spring. . . . the person-based data revealed large differences between - and within - participants in terms of light received at the eye. . . . When designing the lighting plan for a space, the location and placement of light fixtures is a factor that should be considered. Furthermore, large differences occur depending on distance from a window, with individuals being situated further away from a window receiving less light. . . . one could consider paying more attention to the qualities of views outside as a way to stimulate gaze directions towards the window or designing spaces in such a way that it influences the behavior of occupants, encouraging them to move towards lighter spaces during breaks and other activities that do not require desk work.”

Researchers investigated responses to social distancing tools. Taylor lead a team that determined that in restaurant dining rooms “consumer perceptions of the dining room that utilized partitions [to enforce social distancing rules] were significantly greater than those that used mannequins. . . . ‘Results of the current study suggest that consumers have differing perceptions of the cleanliness of the two socially distant servicescapes that were assessed,’ Taylor reported. ‘However, it was not just cleanliness that was found to be perceived significantly differently between the two servicescapes, as respondents indicated that the dining room that has partitions between tables was more visually attractive, cleaner looking, more welcoming, safer looking, more entertaining, more sanitary and more comfortable than the dining room with mannequins.’” This study of responses to servicescapes is published in the Internal Journal of Hospitality Management.

People on the autism spectrum seem to have tactile experiences that are different from those of individuals not on the autism spectrum. This has implications for the design of spaces that are likely to be used by these individuals. A study published in Neurology reports that “‘More than 70% of people with autism have differences in their sensory perception,’ said study author Sung-Tsang Hsieh. . . . 53% of the people with autism had reduced nerve fiber density. . . . People who had reduced nerve fiber density also were more likely to report feeling pain from the heat stimulus at a higher temperature than the control group. . . . response to touch in people with autism differed according to whether or not they had nerve fiber damage. People who had normal nerves were more likely to say they disliked being touched and were uncomfortable with some textures, while people with nerve fiber damage were more likely to say they preferred going barefoot and could be unaware that they had gotten scratched or bruised.”

We seem to have a special ability to remember the locations of high-calorie foods—no wonder our society is tubbier than it should be. De Vries and colleagues “explored whether human spatial cognition is enhanced for high-calorie foods, in a large multisensory experiment that covertly tested the location memory of people who navigated a maze-like food setting. We found that individuals incidentally learned and more accurately recalled locations of high-calorie foods – regardless of explicit hedonic [pleasure-related] valuations or personal familiarity with foods. In addition, the high-calorie bias in human spatial memory already became evident within a limited sensory environment, where solely odor information was available. These results suggest that human minds continue to house a cognitive system optimized for energy-efficient foraging within erratic food habitats of the past.”

Investigators have found that varying lighting in nursing homes during the course of the day, so that light intensity and color mimics lighting conditions outdoors, supports better sleep among residents. Baier, Miller, McCreedy, Uth, Wetle, Noell-Waggoner, Stringer, and Gifford, used data collected from study participants with an average age of 88 to better understand sleep related issues among nursing home residents: “Nursing home residents tend to fall asleep at all hours of the day, and during the night, their sleep may be interrupted by periods of wakefulness. . . . [at] one California nursing home. . . . [in a dynamic lighting condition] the facility installed interior [LED] lighting fixtures that change color and intensity over the course of the day and night [to mimic natural light]. . . . The tuned lighting brightened corridor lighting in the day and dimmed it during the night. The static condition mimicked the fluorescent lighting in place at the facility prior to installation of the tunable fixtures. . . . The study found that, on average, the residents experienced 3.6 nighttime sleep disturbances with static lighting compared to 1.8 with tuned lighting.” Findings are published in Seniors Housing and Care Journal.

Huang and Liu, via a study published in the International Journal of Contemporary Hospitality Management,investigated how the alignment of fonts used with messages presented influences the success of charity appeals. The researchers “asked prospective donors to consider whether and how much to give to a local food bank to help fight hunger during the coronavirus pandemic . . . donors were more likely to give when heartfelt messages were written in typefaces that looked like handwriting, and when messages that talked about the power of an organization were written in typeface that looked more business-like. . . . When the message was a warm one, with a tone that played up the emotions of what the fundraising organization could do, donors were more likely to give when the message was written in font that looked like handwriting. . . . When the message was focused on the competency of the organization, on its efficiency and on its power, donors were more likely to give when the message was written in a font that was clearly generated by a computer.”

Vaez and colleagues studied how people using different wayfinding tools traveled through a place they had never been before. Researchers worked with “three groups of participants who used different navigational aids: a group with a paper map, a group with the Google Maps app, and a group relying on local signage only. . . . participants who had never visited Brisbane, Australia. . . . undertook a two-hour pedestrian wayfinding task. . . . The GPS group preferred to follow the suggested route by their navigator, most of them ‘locking in’ as digital navigators throughout the task. By contrast, the local-signage-only group used a diverse range of strategies to wayfind. Local-signage-only and paper map users tried to locate their position in the city by using piloting or path integration strategies, the GPS group just passively followed the guidance line showed by their device. On completion of the task the digital navigators recognized less spatial information. Surprisingly, the digital navigators did not feel less anxious compared with the two other groups.”

Selections and preferences were probed in a recent study. Silver and colleagues report that “The question of how people’s preferences are shaped by their choices has generated decades of research. In a classic example, work on cognitive dissonance has found that observers who must choose between two equally attractive options subsequently avoid the unchosen option, suggesting that not choosing the item led them to like it less. However, almost all of the research on such choice-induced preference focuses on adults. . . . we examined the developmental roots of this phenomenon in preverbal infants. . . . In a series of seven experiments using a free-choice paradigm, we found that infants experienced choice-induced preference change similar to adults’. Infants’ choice patterns reflected genuine preference change and not attraction to novelty or inherent attitudes toward the options. Hence, choice shapes preferences—even without extensive experience making decisions and without a well-developed self-concept.”

Jonauskaite, Parraga, Quiblier, and Mohr assessed how consistent people’s emotional associations are when they read the name of colors and when they see patches of the same colors. The team found “high similarity in the pattern of associations of specific emotion concepts with terms and patches . . . for all colours except purple. . . . We also observed differences for black, which is associated with more negative emotions and of higher intensity when presented as a term than a patch. . . . results from studies on colour–emotion relationships using colour terms or patches should be largely comparable.” This finding is useful, for example, to designers and researchers developing data collection tools. The researchers studied responses to red, orange, yellow, green, turquoise, blue, purple, pink, brown, white, gray, and black. Color patches used were “the best exemplars of each colour category. . . . which are largely universally recognized.” Also,“Pink, white, green, orange, blue, yellow, and turquoise were all significantly biased towards positive [emotional] associations . . . while black, grey, and brown . . . were significantly biased towards negative associations.” For “Red . . . and purple . . . . . . the same number of positive and negative emotion concepts was on average associated with these colours.” The researchers also report that Labrecque and Milne (2012), interestingly, link viewed black with the ideas of sophistication and elegance.

Stanischewskiand team mates review and extend research related to human responses to curvilinearity and rectillinearity. They share that previous research has shown that “Curvilinearity is a perceptual feature that robustly predicts preference ratings for a variety of visual stimuli. . . . The present results support the idea that people prefer curved stimuli over angular ones overall. Specifically, participants rated curved stimuli as more pleasing and harmonious than the angular stimuli.”
