How does music heard influence exercising? Terry and colleagues reviewed previously published studies and found that “Music was associated with significant beneficial effects on affective valence [mood] . . . physical performance . . . perceived exertion . . . and oxygen consumption. . . . No significant benefit of music was found for heart rate. . . . Overall, results supported the use of music listening across a range of physical activities to promote more positive affective valence, enhance physical performance (i.e., ergogenic effect), reduce perceived exertion, and improve physiological efficiency.”

Krauss and teammates evaluated how the context in which art is shown influences human responses to it via a study in an actual museum. They report that their “study set out to assess the aesthetic experience and psychophysiological responses of participants in an art museum viewing 6 artworks of Flemish expressionism. Participants were randomly assigned to one of the experimental conditions, either receiving elaborative information or descriptive information on the artworks. Aesthetic experiences were assessed via a questionnaire and through psychophysiological markers. A systematic influence of contextual information on aesthetic experience could not be shown. However, artworks had effects on aesthetic experience and heart rate, heart rate variability, skin conductance, and skin conductance variability. The results indicate that the characteristics of the artwork itself have a stronger impact than provided contextual information, at least when they are perceived as originals in a museum.”

McArthur simulated the experience of being in “large offices in all climate zones . . . with various outdoor air rates,” and documented the significant performance/economic benefits that result from relatively high outdoor air ventilation rates. The researcher shares that “A benefit-cost analysis considered energy costs and carbon emission offsets to achieve net-zero carbon operation for large office buildings across international climate zones with ventilation rates ranging from 125% to 1000% ASHRAE 62.1 minimums. Key findings: (1) the productivity benefit was substantially larger than the incremental energy costs; (2) carbon offset costs were relatively low compared with energy costs and had a negligible effect on results; (3) increasing outdoor air resulted in consistently increasing net benefits on an area basis; and (4) the benefit-cost ratio was inversely proportional to the severity of the climate, with the most moderate climates actually showing a net energy decrease with elevated outdoor air.” A definition: “ANSI/ASHRAE 62.1 defines the minimum allowable outdoor air for all building types excluding low-rise residential buildings.”

Paton and colleagues investigated human responses to sounds that water can make. They report that “16 water sounds, with very different acoustic characteristics in the number of harmonics, fundamental frequencies, spectral information and fractal dimension (=complexity), were sampled. . . . Relationships between sound parameters and comfort responses show that information related to harmonics is behind the preferences. . . . we demonstrated that fountains with large waterfalls or jets, produce a marked acoustic aversion to humans. It is to be expected that the same effect will happen with birds and other small vertebrates present in cities. Instead, we recommend in the design of urban parks and gardens, the adoption of artificial water channels with small jumps whose acoustic characteristics are ideal causing deep and sustained relaxation.”

Jeon and Jo studied the effects of visual and acoustic information on satisfaction with urban environments and it is likely that their findings are applicable in other contexts. The duo determined that when “Actual site conditions were simulated using immersive virtual reality technology in which subjects were provided with visual information via a head-mounted display (HMD) and audio information via head-tracking technology using the first-order ambisonics (FOA) of headphone-based three-dimensional auralization. . . . It was shown that the availability of visual information affects the auditory perception of a number of human-made and natural sounds and the availability of audio information affects the visual perception of various visual elements. . . . One new finding was that audio information affects the perception of the naturalness of a landscape. Audio and visual information had effects of 24 and 76%, respectively, on overall satisfaction.”

Via aseries of studies, Wijaya and colleagues explored aspects of our sense of touch. They determined that materials experienced as smooth, slippery, and soft were perceived as pleasant when rubbed on a human forearm.

Tham and colleagues investigated associations to particular colors at a cultural level using language groups (adults who only spoke English, who only spoke Chinese, or who were bilingual in English and Chinese). Their “findings reveal conceptual color associations that appear to be universal across all cultures (e.g., white – purity; blue – water/sky related; green – health; purple – regal; pink – “female” traits) as well as culture specific (e.g., red and orange – enthusiastic in Chinese; red – attraction in English).”

Siri and colleagues investigated whether the format of a piece of visual art influences how it is perceived by viewers. The team had people look at abstract works of art, without knowing if the piece they were looking at was an original or a digital reproduction of that original. The researchers collected physiological data related to participant energy level and “participants provided behavioral ratings of color intensity, emotional intensity, aesthetic evaluation, perceived movement, and desire to touch the works of art. . . . results demonstrated that the faithful high-quality digital reproductions of works of art could be as arousing as the original works of art, but at the same time, they cannot replace the experience of standing in front of an authentic work of art in terms of explicit hedonic [pleasure-related] attributed values. . . . participants explicitly attributed higher scores in Emotion and Touch judgments to real works of art than to their digital reproductions. In contrast, no significant differences emerged when participants judged the color intensity, the perceived movement, and the aesthetic value of digital and real works of art.. . . we did not find any difference between authentic works of art and their digital reproductions in terms of physiological measures.”

Samermit and colleagues have determined that pairing disliked sounds (such as “nails scratching a chalkboard”) with videos presenting a more positive explanation for that sound (such as “someone playing a flute”) reduces the negative implications of hearing those sounds. They report that “We propose that cross-sensory stimuli presenting a positive attributable source of an aversive sound can modulate negative reactions to the sound.” The researchers utilized “original video sources (OVS) of eight aversive sounds (e.g., nails scratching a chalkboard) . . . .[and] positive attributable video sources (PAVS) of those same sounds (e.g., someone playing a flute)” as well as sound only recordings of the aversive sounds. The researchers determined that “compared to the sounds alone . . . concurrent presentation of PAVS videos significantly reduced negative reactions to the sounds, and the concurrent presentation of OVS videos significantly increased negative reactions. . . . Our results provide novel evidence that negative reactions to aversive sounds can be modulated through cross-sensory temporal syncing with a positive attributable video source.” Study participants rated the sounds, when they were presented with the videos and without the videos, on discomfort and unpleasantness, for example.

Research indicates that people have situation-specific reactions to recycled water; reported findings are likely applicable in other contexts with other recycled materials. Gauvain and Harmon determined that “If people are educated on recycled water, they may come to agree it’s perfectly safe and tastes as good — or better — than their drinking water. . . . But that doesn’t mean they’re going to use recycled water — and it sure doesn’t mean they’ll drink it. And the reason lies in the word ‘disgust.’ . . . Past research by Harmon and Gauvain explored whether people sense a difference in taste among recycled water, conventional tap water, and commercially bottled water. That study . . . was based on a blind taste test and found people actually preferred the taste of recycled water over conventional tap water.” Gauvain and Harmon’s results are published in Basic and Applied Social Psychology.
