How food is plated influences how it is perceived; this finding may be applicable in settings that don’t involve those tested. Researchers evaluated “how the plating (i.e., visual composition) of a dish influences people's hedonic preferences and their perception of portion size. . . . the centrally-plated dessert was rated as a larger portion than the offset version of exactly the same dish. The food was also liked more and the participants/diners were willing to pay more for it when . . . centrally arranged. These results provide important guidelines for enhancing the visual arrangement of a dish, in order to increase enjoyment, and possibly also nudge consumers toward better food choices.”

Associations identified between shapes and tastes can realistically be extended to other contexts. Investigators report that “We replicated the results of previous studies showing that round shapes are associated with sweet taste, whereas angular shapes are associated with sour and bitter tastes. . . . These results were consistent across cultures, when we compared participants from Taiwanese and Western (UK, US, Canada) cultures. Our findings highlight that perceived pleasantness and threat are culturally common factors involved in at least some crossmodal correspondences.”

Casner shares important insights into the occasionally baffling ways that humans’ fallible minds interact with the world that surrounds them. His neuroscience-based focus is on situations during which humans injure themselves, and sometimes others, primarily via everyday behaviors of some sort gone wrong. The material in this very readable text can be applied by people developing environments at varying scales, from places/objects to be used by one person to those utilized by groups. Suggestions for improvement shared by Casner are useful to designers with a wide range of skills and experience.

Research by Naz and colleagues confirms that our experiences in real and comparable virtual worlds are fundamentally equivalent. They report that “The emotional response a person has to a living space is predominantly affected by light, color and texture as space-making elements. . . . we conducted a user study in a six-sided projected immersive display that utilized equivalent design attributes of brightness, color and texture in order to assess to which extent the emotional response in a simulated environment is affected by the same parameters affecting real environments. . . . Data from the experiments confirmed the hypothesis that perceivable emotional aspects of real-world spaces could be successfully generated through simulation of design attributes in the virtual space. The subjective response to the virtual space was consistent with corresponding responses from real-world color and brightness emotional perception.”

Hoendervanger and colleagues continue to study the experience of working in activity-based offices. They determined via field and lab studies that “Activity-based work environments are widely adopted; however, research shows mixed findings regarding privacy issues, satisfaction with the work environment, and task performance. . . . The results from both studies confirm that perceived [person-environment] fit is a function of activity, work setting, and personal need for privacy, with indirect effects on satisfaction with the work environment . . . and task performance. . . . Across both studies, a misfit was perceived particularly among workers high in personal need for privacy when performing high-complexity tasks in an open office work setting. Hence, we recommend that organizations facilitate and stimulate their workers to create better fits between activities, work settings, and personal characteristics.”

Herd and Mehta set out to learn more about how to encourage creative thinking. They report that “Imagination visual mental imagery, a mental simulation process that involves imagining an end user interacting with an end product, has been proposed as an efficient strategy to incorporate end-user experiences during new product ideation. . . . The present work delineates the imagination visual mental imagery construct and argues that such mental imagery can take two different routes—one that is more feelings-based (i.e., feelings-imagination), and one that is more objective (i.e., objective-imagination). Further, we propose that although these two approaches will equally benefit outcome usefulness, they will have differential impact on outcome originality. Across five studies, we demonstrate that adopting a feelings-imagination versus an objective-imagination approach induces higher empathic concern, enhancing cognitive flexibility, which leads to higher outcome originality.” An emotion-focused approach can be best when originality is important.

Nearby greenery has again been linked to mental wellbeing. Houlden and colleagues report that their “study was designed to examine whether the amount of greenspace within a radius of individuals’ homes was associated with mental wellbeing, testing the government guideline that greenspace should be available within 300m[eters] of homes. . . . [statistical analyses] revealed positive and statistically significant associations between the amount of greenspace and indicators of life satisfaction and worth. . . . an increase in 1 ha [hectare] of greenspace within 300 m of residents was associated with a statistically significant . . . increase in life satisfaction . . . [sense of self] worth and happiness. . . . This therefore provides some support for the inclusion of greenspace within 300 m of homes.”

Features of neighboring homes influence what we think about our own house. Kuhlmann investigated “whether the size of one’s home relative to others in their [resident’s] neighbourhood influences their housing satisfaction. . . . [and found] evidence that relative position matters. Those living in comparatively small houses are more likely to express dissatisfaction with their home than people living in units that are large relative to other houses in their neighbourhood cluster.”

Schmidt and colleagues wanted to learn more about how nonverbal messages influence how people think and behave. They “recorded participants' EEG brain responses while they played a risk game developed in our laboratory. . . . we predicted that cognitive control would be reduced in the helmet group [that is, people playing the game while wearing a bicycle helmet although they were not near a bicycle], indicated by reduced frontal midline theta power, and that this group would prefer riskier options in the risk game. . . . we found that participants in the helmet group showed significantly lower frontal midline theta power than participants in the control group, indicating less cognitive control. . . . Our results suggest that wearing a bike helmet reduces cognitive control, as revealed by reduced frontal midline theta power, leading to risk indifference when evaluating potential behaviors.” It is likely that the effect observed, tying feeling protected/safe and lower levels of cognitive control, is likely to be found in contexts beyond those tested.

Researchers studying beauty have found that math can be beautiful, just like landscapes and sonatas. A study by Steinerberger and Johnson, published in Cognition,reports that “average Americans can assess mathematical arguments for beauty just as they can pieces of art or music. The beauty they discerned about the math was not one-dimensional either: Using nine criteria for beauty — such as elegance, intricacy, universality, etc. — 300 individuals had better-than-chance agreement about the specific ways that four different [mathematical] proofs were beautiful. . . . For the study, they [researchers] chose four each of mathematical arguments, landscape paintings, and [classical] piano sonatas. . . . The researchers’ nine dimensions elaborated from Hardy’s six were: seriousness, universality, profundity, novelty, clarity, simplicity, elegance, intricacy, and sophistication. . . . for both the artworks and math arguments a high rating for elegance was most likely to predict a high rating for beauty.”
