Research conducted by Gomez and Spielmann confirms that sensory evaluations are regularly more subjective than objective. The researchers found that “Associating food products with elite groups positively influences sensory taste perceptions.. . . .Taste enhancement occurs because of the transfer of unobservable elite properties to the food.. . . In four studies involving actual taste tests and online experiments, we show that associating a food product with an elite group increases taste perceptions within various food categories. This effect occurs because of belief in transferred essence (the belief that the product incorporates the unobservable properties of the social elite). The effect is also stronger among participants highly sensitive to disgust. Overall, our results suggest that a taste experience is improved when foods embody the characteristics of the social elite.”

A research team headed by Bigman identified links between robot appearance and how responsible they are felt to be for their actions. These scientists report that “Even as roboticists create robots with more ‘objective’ autonomy, we note that ‘subjective’ autonomy may be more important. . . . People perceive the mind of machines based on their abilities and behaviors, but also on their appearance. The more human-like a machine looks, the more people perceive it as having a mind, a phenomenon called anthropomorphism. . . . Individuals vary in their tendency to anthropomorphize, but people consistently perceive more mind, and therefore more moral responsibility, in machines that look and act like humans. . . . We suggest that having human-like bodies, human-like voices, and human-like faces will all cause people to attribute more moral responsibility to machines.”

A study to be published in Behavior Research Methodssheds light on relationships between sensory experiences. Cuskley, Dingemanse, Kirby and van Leeuwenanalyzed data collected from over 1,000 people and found that when study participants “chose colours for 16 spoken vowels. A large majority felt that ‘aa’ was more red than green, and ‘ee’ more light than dark. . . . According to Mark Dingemanse, one of the researchers, ‘There seems to be a logic to how we link sound and colour, and the structure of language has an important role in this process.’ . . . Earlier studies have found that colour associations are linked to the pitch of the sounds: the higher the pitch, the lighter the colour. But the new study shows that colour associations are driven to a greater degree by the vowel system of a language.”

Laboratory Lifestyles: The Construction of Scientific Fictions is packed with ideas that can be used to develop scientific laboratories as well as other professional workplaces. Laboratory Lifestyles’website states that “The past decade has seen an extraordinary laboratory-building boom. This new crop of laboratories features spectacular architecture and resort-like amenities. The buildings sprawl luxuriously on verdant campuses or sit sleekly in expensive urban neighborhoods. Designed to attract venture capital, generous philanthropy, and star scientists, these laboratories are meant to create the ideal conditions for scientific discovery. Yet there is little empirical evidence that shows if they do. Laboratory Lifestyles examines this new species of scientific laboratory from architectural, economic, social, and scientific perspectives.”

Obayashi and teammates studied how airflow and concentration are related. They evaluated the mental activity of people in two areas, one with no airflow and another with an airflow system combining two different ventilation experiences, one of which was labeled “stimualtive” and the other “mild.” During the study, “cognitive tasks are given to participants. The concentration time ratio (CTR), which is a quantitative and objective evaluation index of the degree of concentration, is measured. . . . the average CTR under the proposed airflow condition [the one with the mild and stimulative components] is 61.1%, while under the no airflow condition is 54.6%. The proposed airflow control shows a significant improvement in CTR.” More information on the stimulative/mild airflow: “The velocity of mild airflow fluctuates from 0 m/s to 0.4 m/s. . . . . The transition of mild airflow velocity . . . [has a cycle of] 120 s. . . . the velocity of stimulative airflow was fixed to 1.6 m/s. These velocities were measured at 1.1 m high, which is close to head height when the subjects are sitting. Stimulative airflow was applied for 20 s every 10 min.”

A new study confirms how powerful visual cues can be. Chan and Maglio determined that “Just looking at something that reminds us of coffee can cause our minds to become more alert and attentive. . . . Across four separate studies and using a mix of participants from Western and Eastern cultures, they [the researchers] compared coffee- and tea-related cues. They found that participants exposed to coffee-related cues perceived time as shorter and thought in more concrete, precise terms. . . . the effect was not as strong among participants who grew up in Eastern cultures. Maglio speculates that the association between coffee and arousal is not as strong in less coffee-dominated cultures.” The Chan/Maglio study is published in Consciousness and Cognition.

Weir reviews research in the field of neurogastronomy. The field is defined in her article as “combining the molecular biology of olfaction, the biochemistry of food preparation and the neuroscience of sensation and perception.” Weir reports, for example that when someone is tasting something “The process starts even before you take a bite. You smell the food’s aroma and see its shape and color, as well as the appearance of the plate or bowl. . . . aroma from the food is carried through the inside of the mouth up into the nose . . . which has a big effect on flavor. . . . Spence’s [Spence is a professor of experimental psychology at the University of Oxford] research reveals how input from our ears, eyes and fingertips influences the taste of foods. He’s shown that yogurt, for example, is perceived as denser and more expensive when tasted with a light plastic spoon rather than a weighty metal one . . . and eating chocolate while listening to musical compositions with soft, smooth notes makes the chocolate seem creamier.”

Miller and Hubner found that individuals are pretty good at determining if other people will like a particular piece of art. The duo reports that “Aesthetic preferences vary strongly between people. Yet, it can be essential to infer what other people aesthetically prefer. Therefore, we investigated lay people’s ability to infer aesthetic preferences. . . . about half of the participants produced a significant medium to high correlation between their other assessments and the mean others′ self-assessment. . . . our results indicate that many individuals are able to infer aesthetic preferences.”

On March 22, at the Outcome of Design (OOD) conference organized by the American Society of Interior Designers, OOD award winning projects were reviewed. One of the awarded projects is a waiting area at Unity Health Care Brentwood, redesigned by Gensler in partnership with others, including Sunbrella. The new space was developed using data collected via surveys, observations, behavioral mapping, and community outreach. The printed agenda for the Outcome of Design conference indicated that in the new waiting room “wider seat selections and increased spacing between seats resulted in increased utilization. In the original design, patients spread out into two to three seats to define their personal space. In the new design, patients utilized one to two seats.”
Just, Nichols, and Dunn evaluated indoor climates across the United States. They studied “indoor climate data from homes . . . across the USA. We then compared these data to recent global terrestrial climate data (0.5° grid cells, n = 67 420) using a climate dissimilarity index. . . . On average, our study homes were most similar in climate to the outdoor conditions of west central Kenya. . . . Overall, we identified the geographical distribution of the global outdoor climate that is most similar to the interiors of our study homes and summarized study home indoor climate preferences. . . . the temperature people prefer overlaps with much of the geographical area in which key events in hominid evolution and, for that matter, early civilization occurred. . . . We hypothesize that natural selection favoured human preferences and thermal traits that allowed human ancestors to live in those climates.” Insights drawn from this work by Just and colleagues can inform future design decisions that influence the “climates” experienced by space users.
