Temporal Dimensions

This study examines whether global tempo and expressive timing microstructure are independent in the aesthetic judgment of music performance. Measurements of tone interonset intervals in pianists' performances of pieces by Schumann ("Traumerei") and Debussy ("La fille aux cheveux de lin") at three different tempi show a tendency toward reduced relative variation in expressive timing at both faster and slower tempi, relative to the pianist's original tempo. However, this could reflect merely the pianists' discomfort when playing at an unfamiliar tempo. Therefore, a perceptual approach was taken here. Experimental stimuli were created artificially by independently manipulating global tempo (three levels) and "relative modulation depth" of expressive timing (RMD, five levels) in MIDI-recorded complete performances of the Schumann and Debussy pieces. Skilled pianists rated the quality of the resulting two sets of 15 performances on a 10-point scale. The question was whether the same RMD would receive the highest rating at all three tempi, or whether an interaction would emerge, such that different RMDs are preferred at different tempi. A small but significant interaction was obtained for both pieces, indicating that the listeners preferred a reduced RMD when the tempo was increased, but the same or a larger RMD when the tempo was decreased. Thus, they associated an increase in tempo with a decrease in (relative) expressive timing variation, which, in general agreement with the performance data, suggests that the two temporal dimensions are not independent.

The Aesthetic

Discussions of music performance often stress diversity and artistic freedom, yet there is general agreement that interpretation is not arbitrary and that there are standards that performances can be judged by. However, there have been few objective demonstrations of any extant constraints on music performance and judgment, particularly at the level of expressive microstructure. This study illustrates such a constraint in one specific case: the expressive timing of a melodic gesture that occurs repeatedly in Robert Schumann's famous piano piece, "Traumerei." Tone onset timing measurements in 28 recorded performances by famous pianists suggest that the most common " temporal shape" of this (nominally isochronous) musical gesture is parabolic and that individual variations can be described largely by varying a single degree of freedom of the parabolic timing function. The aesthetic validity of this apparent constraint on local performance timing was investigated in a perceptual experiment. Listeners judged a variety of timing patterns (original parabolic, shifted parabolic, and nonparabolic) imposed on the same melodic gesture, produced on an electronic piano under control of a Musical Instrument Digital Interface (MIDI). The original parabolic patterns received the highest ratings from musically trained listeners. (Musically untrained listeners were unable to give consistent judgments.) The results support the hypothesis that there are classes of optimal temporal shapes for melodic gestures in music performance and that musically acculturated listeners know and expect these shapes. Being classes of shapes, they represent flexible constraints within which artistic freedom and individual preference can manifest themselves.

Human Faces

A statistically average or prototypical member of a category (e.g., human faces) is often perceived as more attractive than less typical category members. Two experiments explored to what extent this may hold for music performance, an artistic domain in which individuality (i.e., deviation from prototypicality) is highly valued. In Experiment 1, graduate student pianists judged 11 student performances of Schumann's "Traumerei," one of which was created by forming the mathematical average of the other 10. The average performance was rated second highest in quality, even though it was judged second lowest in individuality. In Experiment 2, pianists judged 30 performances of the beginning of Chopin's Etude in E major, synthesized so as to vary only in expressive timing and tempo. The timing patterns were derived from expert pianists' recordings and from casual student performances, and they included separate and combined averages. All three averages received high quality ratings, and the expert average was rated highest of all 30 performances. There was a negative linear correlation between rated quality and individuality. Paradoxically, therefore, the students' expressive timing patterns were preferred over the experts'. Possible explanations of this finding are discussed, such as interactions between timing and other performance parameters and conditions under which conventionality tends to be favored over individuality.

In human-computer interaction, the visual interaction of user experience (UX) and user interface (UI) plays an important role in enriching the quality of daily life. The purpose of our study analyzes the use of brain-computer interface (BCI), wearable technology, and functional magnetic resonance imaging (fMRI) to explore the aesthetic processing of visual neural response to UI and UX designs. Specifically, this review aims to understand neuroaesthetic processing knowledge, aesthetic appreciation models, and the ways in which visual brain studies can improve the quality of current and future UI and UX designs. Recent research has found that subjective evaluations of aesthetic appreciation produce different results for objective evaluations of brain research analysis. We applied SWOT analysis and examined the advantages and disadvantages of both evaluation methods. Furthermore, we conducted a traditional literature review on topics pertaining to the use of aesthetic processing knowledge in the visual interaction field in terms of art therapy, information visualization, website or mobile applications, and other interactive platforms. Our main research findings from current studies have helped and motivated researchers and designers to use convincing scientific knowledge of brain event-related potential, electroencephalography, and fMRI to understand aesthetic judgment. The key trend finds that many designers, artists, and engineers use artistic BCI technology in the visual interaction experience. Herein, the scientific methods applied in the aesthetic appreciation to human-computer interface are summarized, and the influence of the latest wearable brain technology on visual interaction design is discussed. Furthermore, current possible research entry points for aesthetics, usability, and creativity in UI and UX designs are explicated. The study results have implications for the visual user experience research domain as well as for interaction industries, which produce interactive projects to improve people’s daily lives.

Machine Interaction

In this article, the authors analyze the process of humanmachine interaction in the context of artistic domains, as a framework for exploring creativity and producing results that could not be obtained without such interaction. “ArTbitration” denotes a process aimed at improving users' aesthetic judgment involving evolutionary computation and other computational intelligence methodologies. The authors interpret it as an interactive, iterative optimization process. They also suggest ArTbitration as an effective way to produce art through the efficient manipulation of information and the proper use of computational creativity to increase the complexity of the results, without neglecting the aesthetic aspects. The article emphasizes the spoken, visual and musical domains, since these are generally characterized by the lack of a systematic way to determine the quality of the result.

Aesthetic Judgments

179 British students rated the aesthetic appeal of 131 designs and 135 polygons on a 5-point scale. Similar judgments were made by 115 Japanese students who did not, however, rate both designs and polygons but rather one or the other set. Correlations between mean ratings for the designs and polygons were uniformly positive and high, suggesting the comparative absence of cultural factors determining aesthetic judgments in this field. The data were interpreted as favouring Eysenck's theory of a general factor of aesthetic judgment in the visual field.

This chapter argues for the importance of cultivating aesthetic literacy and vigilance, as well as practicing aesthetic expressions of moral virtues. In light of the considerable power of the aesthetic to affect, sometimes determine, people’s choices, decisions, and actions in daily life, everyday aesthetics discourse has a social responsibility to guide its power toward enriching personal life, facilitating respectful and satisfying interpersonal relationships, creating a civil and humane society, and ensuring the sustainable future. As an aesthetics discourse, its distinct domain unencumbered by these life concerns needs to be protected. At the same time, denying or ignoring the connection with them decontextualizes and marginalizes aesthetics. Aesthetics is an indispensable instrument for assessing and improving the quality of life and the state of the world, and it behooves everyday aesthetics discourse to reclaim its rightful place and to actively engage with the world-making project.

The priority in improving the existing methods of processing fish is salting with the use of food additives with different functional orientations. The aim of the study was the development of preserves with the introduction of lactate-containing additives and using sonochemical technologies; examination of the quality of the products obtained according to organoleptic and microbiological safety indicators. The article proposes a resource-saving technology for the production of fish products with prolonged shelf life due to the use of a complex food additive consisting of lactic, acetic, propionic acids and their salts in different proportions with subsequent ultrasonic treatment using the ultrasonic generator of the Wave series model UZTA-0 2/22-OM. There was established the optimal mode of using the ultrasonic processing power of 75 W / m2 in the manufacture of fish preserves from herring. Organoleptic and microbiological quality indicators were studied during storage of preserved products with the addition of additives and ultrasonic treatment compared to the control. Organoleptic assessment was carried out on a five-point scale, microbiological indicators were studied by standard methods. The Dilactin Forte Plus dietary supplement in the composition of preserves in the amount of 3% and in combination with the use of sonochemical technologies makes it possible to obtain a safe high-quality fish product. Manufactured preserves at a storage temperature of 0 ± 2 ° C can maintain their high quality for 5 months.
