Walking through the city soundscape: an audio-visual analysis of sensory experience for people with psychosis

This article discusses how an aspect of urban environments – sound and noise – is experienced by people walking in the city; it particularly focuses on atypical populations such as people diagnosed with psychosis, who are reported to be particularly sensitive to noisy environments. Through an analysis of video-recordings of naturalistic activities in an urban context and of video-elicitations based on these recordings, the study details the way participants orient to sound and noise in naturalistic settings, and how sound and noise are reported and reexperienced during interviews. By bringing together urban context, psychosis and social interaction, this study shows that, thanks to video recordings and conversation analysis, it is possible to analyse in detail the multimodal organization of action (talk, gesture, gaze, walking bodies) and of the sensory experience(s) of aural factors, as well as the way this organization is affected by the ecology of the situation.

Sensory Experience as a Regulator of Structural Plasticity in the Developing Whisker-to-Barrel System

Cellular structures provide the physical foundation for the functionality of the nervous system, and their developmental trajectory can be influenced by the characteristics of the external environment that an organism interacts with. Historical and recent works have determined that sensory experiences, particularly during developmental critical periods, are crucial for information processing in the brain, which in turn profoundly influence neuronal and non-neuronal cortical structures that subsequently impact the animals’ behavioral and cognitive outputs. In this review, we focus on how altering sensory experience influences normal/healthy development of the central nervous system, particularly focusing on the cerebral cortex using the rodent whisker-to-barrel system as an illustrative model. A better understanding of structural plasticity, encompassing multiple aspects such as neuronal, glial, and extra-cellular domains, provides a more integrative view allowing for a deeper appreciation of how all aspects of the brain work together as a whole.

Performing Analysis, Performing Metal

Light shows at contemporary rock concerts generally create an immersive, multi-sensory experience. In their most sophisticated forms, however, they provide a visual analysis of the music as it unfolds. This paper presents a case study of what I call the analytical light show, by examining how the intricate light shows of extreme metal band Meshuggah contribute an interpretive layer that not only promotes multi-sensory engagement, but also actively guides listeners through songs’ formal structures. Meshuggah’s light shows, created by lighting designer Edvard Hansson, are exhaustively synchronized to the rhythmic patterns of the guitars and drums. Meticulous use of color, brightness, directionality, placement pattern, and beam movement provide additional information about gesture, articulation, and pitch. These analytical light shows provide a three-dimensional visual score that dramatizes rhythms while guiding listeners through each riff. Through this lighting, spatial and bodily metaphors of musical movement—high and low, moving and holding still—are transmuted into visual representation. By presenting analysis and performance simultaneously and as each other, Meshuggah combines technical virtuosity with rock authenticity, and provides another example of what I have called “coercive synesthesia” (Lucas 2014), as the lighting becomes an inextricable part of the musical experience. Beyond the confines of metal culture, I study the analytical light show as an expression of vernacular musical analysis that combines specific analytical and technical expertise with the intuitive, embodied knowledge that experienced music listeners possess.

DOMESTIC TOURISTS NEW DINING BEHAVIOUR IN RELATION TO COVID-19 AT ISLAND SETTING IN TERENGGANU, MALAYSIA

Today, the tourism industry has grown rapidly and many destinations have been recognised as tourist niches in a bid to stay competitive in the industry. Island tourism is one of the most popular tourism niches. Island tourism in Malaysia has lured tourists from all over the world to come to Malaysia, offering tourist a unique and unforgettable tourism experience. It has become one of the most famous types of activities tourists. Moreover, tourists are showing an increasing interest in local foods at the destination and dining has become a special experience while on vacation. Dining itself is a pleasurable sensory experience that is a key part of the holiday experience, which influences a tourists’ experience and makes it memorable and this in turn influences the tourist’s intention to revisit the destination, especially an island destination. However, the recent COVID-19 pandemic, the subsequent Movement Control Order (MCO) and COVID-19 Standard Operating Procedures (SOP) enforced to control the spread of the pandemic have significantly influenced tourists dining behaviours and perceptions particularly with regard to dine-in options at any food establishment/outlets.

Variations in cigarette brand characteristics: can consumers tell the difference?

ObjectivesSensory experience is an important determinant of smoking initiation, brand choice and harm perception, but little is known about how cigarette design shapes sensory experience. This study reports which variations in tobacco blend and design characteristics available on the market are likely to be perceived as different by consumers.MethodsTruth Tobacco Industry Documents was reviewed for studies showing noticeable sensory differences resulting from variations in tobacco blend and design characteristics. These differences were compared with tobacco product data as available in the Dutch section of the European Common Entry Gate (EU-CEG) system on 30 April 2020.ResultsIndustry documents identified discrimination thresholds for ventilation, pressure drop, tobacco weight, filter length, and tar and nicotine levels in smoke while evidence for other design characteristics was less conclusive. In the 103 different cigarette varieties in the EU-CEG database, five main types of cigarettes could be identified by principal component analysis, differing in (combinations of) design characteristics. The most significant differences between brand varieties were tar, nicotine and carbon monoxide emissions and associated parameters filter ventilation, filter length, cigarette length and tobacco weight.ConclusionsWhile some clusters of brand varieties provided a noticeably different product for consumers, in many cases design differences within these clusters did not exceed the expected discrimination threshold. This indicates that many products on the market are not discernibly different for consumers, and that proliferation of brand varieties has a non-sensory purpose, such as marketing. Policy makers should consider limiting available brand varieties and regulating design characteristics to reduce product appeal.

‘Everyone’s Annoyed’: Leveraging Uncertainty in the Smell of Others

A growing literature illuminates the limits of claims made on the basis of sensory perception in scientized, rationalized, and bureaucratic contexts. How to understand exceptions to the rule – cases where claims based on sensory experience are taken at face value, even without corroborating evidence? Here, I focus on one such exception, in which citizen complaints about the smell of a small shantytown functioned successfully as both demands and justifications despite a lack of the kinds of instrumentally and technologically enabled corroboration that the literature would suggest are necessary to strengthen such claims. I show how complaints slotted neatly into a specific cultural structure, an olfactory cosmology in which ‘bad air’ that endangers health can be identified by smell and requires ongoing management and amelioration, and where adherence to hygienic norms is required for full moral citizenship. The case suggests ways that the apparent weaknesses of olfactory claims might allow them to be uniquely weaponized in social and political life, and shows how such claims can exploit shared norms, values, and meanings to enroll others in the demand for action.
