Researchers have found that initial sensory experiences color responses to future ones.  Jain, Nayakankuppam, and Gaeth, in a study published in the Journal of Behavioral Decision Making,report that “Once a price is mentioned, that number serves as the basis for — or ‘anchors’ — all future discussions and decisions. But new research shows. . . anchoring even occurs in perceptual domains, like sight, sound, and touch. . . .  [the researchers] conducted several studies involving different senses. For example, to test decision-making relating to haptics — or touch — [they] asked subjects to close their eyes and touch sandpaper of a certain grit. When the subjects opened their eyes, he offered them 16 sandpaper choices and asked them to find the grit that matched the first one. Jain anchored the range of options by making participants start with either a relatively finer or coarser grit than the initial one. Those subjects that were anchored with the finer grit chose sandpaper that was finer than the one they originally touched — and the converse was true for those anchored with the coarser grit.” This finding may be useful, for example, to people doing design-related research.

Researchers have found that having COVID-19 seems to influence people’s responses to machines; these findings, published in iScience, have practical implications for both  design and management, for instance. Gratch lead a team that determined that “people affected by COVID-19 [as determined by measurements of stress] are showing more goodwill — to humans and to human-like autonomous machines. ‘The new discovery here is that when people are distracted by something distressing, they treat machines socially like they would treat other people. We found greater faith in technology due to the pandemic and a closing of the gap between humans and machines,’ said Jonathan Gratch. . . . ‘Our findings show that as people interacted more via machines during the past year, perceptions about the value of technology increased, which led to more favorable responses to machines,’ Gratch said.”

Pouso and team evaluated how nature exposure influenced mental health during COVID pandemic lockdowns.  They report that “Using a survey distributed online, we tested the following hypotheses: 1) People will show greater symptoms of depression and anxiety under lockdown conditions that did not allow contact with outdoor nature spaces; 2) Where access to public outdoor nature spaces was strictly restricted, (2a) those with green/blue nature view or (2b) access to private outdoor spaces such as a garden or balcony will show fewer symptoms of depression and anxiety, and a more positive mood. Based on 5218 responses from 9 countries, we found that lockdown severity significantly affected mental health, while contact with nature helped people to cope with these impacts, especially for those under strict lockdown. People under strict lockdown in Spain (3403 responses), perceived that nature helped them to cope with lockdown measures; and emotions were more positive among individuals with accessible outdoor spaces and blue-green elements in their views.”

Park and Lee’s research findings will be of interest to people concerned about crime prevention through environmental design.  The research duo collected data from people who are not burglars using virtual reality. Park and Lee report that their “study examines how the environmental features of residential property influence the choice of intrusion routes in a burglary, based on the assumption that burglars mainly judge whether there are proper intrusion routes rather than assessing the entire house. . . . participants tended to consider the risk of detection when comparing intrusion routes that do not function as normal entrances, such as the side-window and the 2nd-floor window. . . . Such a finding that the attributes of various environmental cues have a significant effect on the selection of the intrusion route implies that the intrusion route (not the entire house) should be considered as a basic unit when evaluating the vulnerability of a house to burglary and developing burglary prevention design strategies.”

Olszewska-Guizzo and colleagues studied links between nature experiences and the psychological state of people who lived in Singapore during its 7 week COVID-19 lockdown (known as a stay-at-home order or SHO).  Data assessed were collected before the COVID-19 pandemic and immediately after the SHO ended.  The research team determined, by showing participants videos of urban public spaces (Busy Downtown, Residential Green, and Lush Garden) filmed before the pandemic that “Post SHO, brain activity and responsiveness to landscapes changed. . . .  high nature exposure [for example, going to parks] reported by Singaporeans during the SHO did not contribute to mitigating [reducing] the risk of depression.”  The authors point out that during the SHO more people visited green spaces than usual, so there was less access to seating areas where visitors could relax and also that wearing masks and crowding, for example, may have kept pandemic related issues top-of-mind.  In addition,“mask-wearing itself could have caused more sweating and/or breathing difficulties, especially in Singapore's tropical climate, which potentially degraded the overall nature experience.”  In conclusion, “The provision of fully-functioning green urban spaces even in the times of pandemic, i.e. allowing social isolation, rest and relaxation in nature, forgetting about the pandemic struggles, may be the key for improved well-being of urbanites post-COVID-19.”

Buxton and colleagues reviewed published studies on the implications of hearing nature sounds.  They determined that “natural sounds improve health, increase positive affect [mood], and lower stress and annoyance. . .  .  Our review showed that natural sounds alone can confer health benefits. . . . water sounds had the largest effect on health and positive affective outcomes, while bird sounds had the largest effect on alleviating stress and annoyance.”

Adams’ text is a useful to designers intrigued by the idea of exploring the implications of design decisions.  He writes in his introduction that the chapters in his book “delve into the sociological, psychological, and historical reasons for our responses [to design].  I explored these issues as a designer, as I am not a neurologist, psychologist, or sociologist.  What visual and conceptual cues resonate, and why?  This was my constant question.”

Theodorson and Scott researched lighting preferences.  They report that their “research explores the human response to colored lighting with light emitting diodes (LEDs) in a space with the intent of understanding preference and affectual [emotional] response.  The research was conducted through photographic appraisal of a single interior space illuminated with monochromatic and mixed colored lighting. Results indicate that. . . . When mixed color lighting is introduced, there are preferences for warm colors.”

Bisson studied experiences in urban environments.  Research completed indicated that “three levels of understanding of urban environments can be identified: a first level shared by all, a second one shared by social groups, and a last one related to the individual. These three-levels of the inhabitants’ definition of urban ambiance anchors enable us to question participation in urban planning.”

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]. . . . findings suggest that lower levels of green space in residential surroundings, during early childhood, may be associated with a higher risk of developing ADHD.”
