Bacevice and colleagues continue to study the experiences of people working at co-working locations. In their newest work, the researchers determined via survey data collected in 2017 and 2018 from WeWork members in the United States that “members strongly identify with their work organizations . . . even after working in the WeWork office for a long period of time. . . . people experience positive outcomes when their work environment aligns with their company’s brand messaging and values. When we organized the comments that describe how WeWork positively shapes professional identity, we found .  . . .Coworking spaces give some members a sense of professionalism and credibility that traditional remote working does not. . . . Workers with company-subsidized memberships feel that their employers take their needs seriously — regardless of where they are located. . . . Coworking spaces help new businesses make a positive impression on potential clientele.”  An important definition:  the researchers defined “identity” as “the extent to which one feels emotionally, psychologically, and subjectively bound to an employer (or any other platform they work for).”

Research by Sayette and team confirms the value of adding pleasant scents to spaces and objects.  The investigators “investigated the strategic use of OCs [olfactory cues] to reduce cigarette craving. . . . smokers . . . initially sampled and rated a series of OCs. Participants then were exposed to . . . smoking cues, which produced robust cigarette cravings. During peak craving, they were randomly assigned to sniff one of three types of OCs (all of which they had previously sampled) while their craving, and a set of responses thought to be associated with craving, were assessed. OCs that a participant had rated as pleasant reduced craving more than did exposure to odor blank (i.e., neutral) or tobacco-related OCs. This effect persisted over the course of 5 min.”   Previous research has linked smelling pleasant scents to being in a more positive mood and lower stress levels.

Smith’s book sheds light on the ways that cities have, can, and will support human beings as they pursue fundamental goals and motivations.  The functionalities and design patterns that archeologist Smith identifies in ancient cities are still relevant today and urban planners and interested others can gain useful insights into urban design best practices by reading Cities:  The First 6,000 Years.

Basu and Savani reviewed research on ways to present options to individuals; specifically, whether it’s best to detail choices simultaneously (for example, all on a single webpage) or one at a time (for instance, on webpages presented in sequentially).  The duo found that “When choosing among multiple options, people can view the options either one at a time or all together. . . .we review an emerging stream of research that examines the ways in which viewing options sequentially as opposed to simultaneously influences people’s decisions. Multiple studies support the idea that viewing options simultaneously encourages people to compare the options and to focus on the ways in which the options differ from each other. In contrast, viewing options sequentially encourages people to process each option holistically by comparing the option with previously encountered options or a subjective reference point.”  So, we are likely to make better choices when options are presented simultaneously.

Levitan, Winfield, and Sherman evaluated responses to representational visual art and found, not surprisingly, that people prefer paintings whose subject matter they like.  The Levitan team reports that “Prior research has demonstrated that color preferences are driven by preferences for objects associated with those colors (e.g., that the sky is blue or that feces are brown influences preferences for blue and brown; Palmer & Schloss, 2010). . . . Our work demonstrates that, despite the seeming subjectivity of art preferences, subject matter significantly influences the formation of preferences. . . . art preferences can be, at least partially, predicted by one’s preferences for the objects depicted in the art.”

A research team lead by Legendre found that we process significant amounts of sensory information while asleep, which has implications for the design of a range of spaces, from homes to healthcare facilities.  The investigators report that “the sleeping brain continues generating neural responses to external events, revealing the preservation of cognitive processes ranging from the recognition of familiar stimuli to the formation of new memory representations.Why would sleepers continue processing external events and yet remain unresponsive? Here we hypothesized that sleepers enter a ‘standby mode’ in which they continue tracking relevant signals, finely balancing the need to stay inward for memory consolidation with the ability to rapidly awake when necessary. . . . we demonstrate that the sleeping brain amplifies meaningful speech compared to irrelevant signals. However, the amplification of relevant stimuli was transient and vanished during deep sleep. . . . the selection of relevant stimuli continues to operate during sleep but is strongly modulated by specific brain rhythms.”

Graziose and colleagues investigated how sound levels influence food consumed and their findings have implications, generally, for situations when designers want to encourage certain behaviors, particularly by children.  The researchers report that “A digital photography method was used to assess FV [fruit and vegetable] consumption among [second and third grade] students across 40 days from 20 schools and environmental exposures, including the noise or sound pressure level of the cafeteria, were assessed during lunch. . . . . Combined FV [fruit and vegetable] consumption was negatively associated with noise exposure. . . Among young children eating in cafeterias, increased noise levels may decrease consumption of fruits and vegetables at the school lunch meal. We hypothesize that increased noise can work in two ways to decrease FV consumption: increased socializing (i.e., talking) and/or decreased hedonic [pleasure-related] enjoyment of the school lunch meal.”

Hsieh and colleagues have found that the color of websites influences shopper opinions.  The researchers determined that “online consumers' reactions to online merchandise prices vary according to website background colors. Participants who view blue or low-brightness backgrounds have high patronage intentions regardless of whether prices are high or low. Participants who view red or high-brightness backgrounds are sensitive to merchandise prices and react significantly negatively to high prices. . . . Blue backgrounds make consumers use high price as a sign of high quality rather than monetary sacrifice, but red or high-brightness backgrounds make consumers use high price as a sign of high monetary sacrifice rather than product quality.”

Research indicates that as lighting levels decrease, people drive more quickly.  De Bellis and colleagues “examine[d] real-world speeding behavior and its interaction with illuminance, an environmental property defined as the luminous flux incident on a surface. Drawing on an analysis of 1.2 million vehicle movements, we show that reduced illuminance levels are associated with increased speeding. This relationship persists when we control for factors known to influence speeding (e.g., fluctuations in traffic volume) and consider proxies of illuminance (e.g., sight distance).”
