Researchers have determined that looking at plants and guided meditation have similar effects on our mental state. Archary and Thatcher studied recovery from mental fatigue (which degraded mood) and found that “distress significantly decreased for participants in the indoor plant break condition while distress significantly decreased . . . in the guided meditation break condition. Indoor plants and guided meditation had a small, but significant positive impact on [mood] restoration. . . . Indoor plants are a cost-effective green ergonomics intervention in offices. This study found that a rest break with indoor plants was as effective as a rest break with guided meditation for affective [mood] restoration after [mental] fatigue.”

Researchers have investigated responses to wood used in built environments in cities; it is possible that their findings are relevant in other contexts.  A press release from the Karlsruhe Institute of Technology reports that a recent study based there “examines how timber construction can make a comeback in cities. Its proposition is that more color is the key to greater acceptance. . . . the requirements of present-day urban planning are forming entirely new connections with the structural principles of timber construction. . . . The authors . . . advocate plywood surfaces and laminated ceilings, structural rather than chemical wood protection, ecologically sound planting schemes – and more color. ‘Color is timber construction’s admission ticket to urban architecture,’ says Falk Schneemann . . . one of the three authors of the study. . . . ‘It inspires acceptance and facilitates the conceptual integration of wooden structures into established urban neighborhoods.’ In addition, modern wood stains that pose no health hazards protect the wood against harmful environmental influences such as exhaust fumes, ultraviolet radiation, and fungi.”

Shi, Mai, and Mo investigated links between the shapes of products and the opinions formed of them.  They report that “this research explores how anthropomorphic products’ humanlike body shapes influence consumer evaluation and purchase intention (PI). Findings . . . indicate that a chubby product shape is more likely to trigger perceptions of Agreeableness, whereas a thin humanized shape is more likely to trigger perceptions of Conscientiousness. Moreover, product attitudes are more favorable and PI is higher when products’ internal attributes (i.e., warmth and competence) match product humanized body shapes (i.e., chubby shape-warmth attribute or thin shape-competence attribute) than when shapes and product attributes mismatch. . . . This research suggests the effectiveness of product design based on congruity between anthropomorphic product shapes (i.e., chubby and thin shapes) and internal attributes (i.e., warmth and competence attributes). A chubby-shaped product generates more favorable product evaluation and higher PI when warmth is its internal attribute. Such preference and higher PI are found for thin anthropomorphic products with the competence attribute.”

Trupp and colleagues learned that there are significant psychological benefits to looking at visual art and cultural content electronically, even for brief periods of time.  The researchers report that “When experienced in-person, engagement with art has been associated—in a growing body of evidence—with positive outcomes in wellbeing and mental health. . . . Participants [in this study] . . . were asked to engage with one of two online exhibitions from Google Arts and Culture (a Monet painting or a similarly-formatted display of Japanese culinary traditions).  With just a 1-2 min exposure, both improved negative mood, state-anxiety, loneliness, and wellbeing. . . . improvements in mood correlated with aesthetic appraisals and cognitive-emotional experience of the exhibition. . . . The ‘non-art’ stimulus. . . . explored a diagram in the shape of a bento box, containing photos and facts introducing the viewer to the history and traditions of Japanese food, and included images of food and food-related activities, such as harvesting or drinking.”

Krpan and van Tilburg add to our knowledge of what is perceived to be beautiful.  They share that they “developed and empirically evaluated the Aesthetic Quality Model, which proposes that the link between [visual] complexity and beauty depends on another key visual property—randomness. According to the model, beauty judgements are determined by an interaction between these two properties, with more beautiful patterns featuring comparatively high complexity and low randomness. The model further posits that this configuration of complexity and randomness leads to higher beauty because it signals quality (i.e., creativity and skill). Study 1 confirmed that black and white binary patterns were judged as more beautiful when they combined high complexity with low randomness. Study 2 replicated these findings using an experimental method and with a more representative set of patterns, and it pointed to quality attribution as a candidate mechanism underlying the beauty judgements.”

Jiang and teammates studied humans’ responses to multicolor light in the context of space travel, but their findings are likely to be relevant in other situations.  The group shares that “The goal of this study . . . was to test whether multicolour lighting can improve people’s psychological state in an isolated and confined environment over a period of seven days. . . . [participants] were randomly divided into two groups:  one group that was exposed to multicolour lighting and a control group, which was exposed to a static, monotonous white interior. . . . The results of the control group showed that the participants’ negative emotions and anxiety continued to increase over time, whereas the group randomly exposed to multicolour lighting that changed every three hours did not show any significant increase in negative emotions and anxiety. Moreover, the random change of light colour . . . appeared to help the participants increase their sense of surprise, thereby counteracting monotony.”  The multicolor light studied was produced by Philips Hue Bluetooth wireless 16 million color dynamic light bulbs.

What neighborhoods can kids and their parents benefit from being in?  Hunter and colleagues set out to answer this question.  Their goal was “To identify features parents perceived as being relevant for their child’s active play, their own active recreation, and their coactivity. Parents . . . with preschoolers . . . living in Edmonton, Canada were recruited. . . . Parents reported demographic information and the importance of several neighborhood features (destinations, design, social, safety, esthetics) for their child’s active play, their own active recreation, and their coactivity via six-item Likert scales. . . . The majority of parents reported that 23 of the 32 neighborhood features were perceived as being relevant for all activity domains. These included destinations (parks, playgrounds, arenas, schools, sport fields, arenas/ice rinks, river valley/ravine), design features (quiet streets, trails, sidewalks), social features (friends/family, child’s friends, other children playing outside, knowing neighbors, trusting neighbors), safety features (street lighting, crime, traffic, daylight, sidewalk maintenance, crosswalks), and esthetic features (cleanliness, natural features).”

Research completed at the University of Florida confirms that there are significant psychological benefits linked to gardening.  Researchers determined via a study published in PLoS ONE that “many people may indeed reap mental health benefits from working with plants — even if they’ve never gardened before. . . . gardening activities lowered stress, anxiety and depression in healthy women who attended twice-weekly gardening classes. None of study participants had gardened before. . .  . In the gardening sessions, participants learned how to compare and sow seeds, transplant different kinds of plants, and harvest and taste edible plants.”

Thielsch, Forthmann, Brau, and Eisbach probed the factors that influence responses to product aesthetics, focusing on household appliances.  The researchers report that “we have developed the Product Aesthetics Inventory (PAI) and its short version, the PAI-S. . . . data [collected] were used to determine the number of product aesthetics factors . . . We found an eight-factor structure consisting of the dimensions Visual Aesthetics, Operating Elements, Logo, Feedback Sounds, Operating Sounds, Haptic, Interaction Aesthetics, and Impression.”

Researchers have investigated the consequences of smelling the sorts of odors present in deserts when it rains.  Nabhan, Daugherty, and Hartung found that “Desert dwellers know it well: the smell of rain and the feeling of euphoria that comes when a storm washes over the parched earth. That feeling, and the health benefits that come with it, may be the result of oils and other chemicals released by desert plants after a good soaking. . . . ‘The Sonoran Desert flora is one of the richest in the world in plants that emit fragrant volatile oils, and many of those fragrances confer stress-reducing health benefits to humans, wildlife and the plants themselves,’ said Gary Nabhan. . . . ‘The fragrant volatile organic compounds from desert plants may in many ways contribute to improving sleep patterns, stabilizing emotional hormones, enhancing digestion, heightening mental clarity and reducing depression or anxiety,’ Nabhan said.”
