AbstractResearch in the field of multisensory perception shows that what we hear can influence what we see in a wide range of perceptual tasks. It is however unknown whether this extends to the visual perception of risk, despite the importance of the question in many applied domains where properly assessing risk is crucial, starting with financial trading. To fill this knowledge gap, we ran interviews with professional traders and conducted three laboratory studies using judgments of financial asset risk as a testbed. We provide evidence that the presence of ambient sound impacts risk perception, possibly due to the combination of facilitatory and synesthetic effects of general relevance to the perception of risk in many species as well as humans. We discuss the implications of our findings for various applied domains (e.g., financial, medical, and military decision-making), and raise new questions for future research.

The Impact

This study investigated the impacts of different notification modalities used in low and high ambient sound environments for mobile phone interaction. Three different notification modalities—Shaking Visual, Shaking Visual + Vibration, and Vibration—were designed and experimentally tested by asking users to conduct a maze task. A total of 72 participants were invited to take part in the experiment through the convenience sampling method. The generated results indicated that (1) the notification modality affects participants’ task completion time, (2) the error rate pertinent to the number of notifications is positively related to the participants’ task completion time, and (3) the ambient sound level and notification modalities impact the overall experience of the participants. The main contributions of this study are twofold. First, it verifies that the multi-dimensional feature of a Shaking Visual + Vibration synesthesia notification design is implementable. Second, this study demonstrated that the synesthesia notification could be feasible for mobile notification, and it was more perceptible by the users.

Cortisol Levels

Purpose: The purpose of this study was to examine coregulation between mothers and preterm infants in hypothalamic-pituitary-adrenocortical (HPA) system activity, as indicated by salivary cortisol levels, while mothers held their infants. The research questions were (a) does mother—infant coregulation in HPA activity occur during holding? and (b) if mother— infant coregulation in HPA activity exists during holding, do type of holding, antenatal steroids, sound level, and maternal touch influence this coregulation? Sample: The sample consisted of 20 mother— infant dyads with infants at a mean postconceptional age of 34.7 weeks (+0.7) and average postnatal age of 15 days (+9) at the time of cortisol sampling. Design: The design was exploratory using convenience sampling. Maternal and infant cortisol levels were obtained at Time 1 (baseline) and Time 2 (end of holding); at each time, the absolute differences in levels between mother and infant were determined. Coregulation was operationalized as less difference between maternal-infant cortisol levels immediately after holding (Time 2) as compared to before holding (Time 1). Results: The two variables with the highest correlation with the Time 1/Time 2 difference score included antenatal steroids and ambient sound level, which were entered into a linear regression equation as predictor variables. A coregulatory relationship in cortisol levels existed between mothers and infants during holding, which was moderated by sound levels. Nurses in the neonatal intensive care unit (NICU) can facilitate the mother—infant relationship, as reflected in coregulatory measures, by promoting a quiet environment, particularly around mothers who are holding their infants.

Ambient Music

Abstract Music from the Hearts of Space, a freeform music program that aired across Northern California on KPFA-FM Pacifica Radio from 1973, set forth an expansive transgeneric vision of contemplative atmospheric “space music” whose properties, in the following decades, would become more popularly codified as either “new age” or “ambient.” Histories of these latter genres typically separate out ambient’s avant-garde lineage and secular functionalism from new age’s therapeutic and spiritual concerns; but an examination of Hearts’s first decade on the air, leading up to its 1983 syndication via National Public Radio’s satellite network, reveals a sonic and cultural milieu that belies this eventual generic split. Through investigation of Hearts’s private archive and interviews with the program’s host Stephen Hill, as well as industry research, cultural-historical study, and style analysis, I situate the genesis of Hearts’s proto-ambient sound within the Bay Area’s new age movement of the 1970s and early 1980s. Informed by the metaphor of the global media environment established in systems theory and popularized by Marshall McLuhan and Stewart Brand, artists and media producers within this grassroots technoculture designed and spread “alternative” personal media for the development of holistic awareness. These media included slow, reverberant, hypnotic recorded music, as curated by Hill and his cohost Anna Turner under the guiding concept of “space music.” This early history and analysis of Hearts’s space music as an atmospheric medium for attuning the listening self to a worldwide media ecology deepens and complicates genealogies that isolate the formation of ambient music from that of new age, revealing a cross-pollination of highbrow and countercultural ideals that led many musicians associated with the new age movement to similar sonic conclusions to those of ambient music architect Brian Eno.
