RESUMEN

Consonance perception has been extensively studied in Western adults, but it is less clear how this perception develops in children during musical enculturation. We investigated how this development occurs in 4- to 6-year-old children by examining two complex musical skills (i.e., consonance and tonality preferences). Accordingly, we developed a child-focused approach to understand the underlying developmental processes of tonality and consonance preferences in 4- to 6-year-old children using a video interview format. As previous studies have confounded preference with perception, we examined each concept separately and measured perceptual abilities as categorization. For tonality, the ability to categorize tonal and atonal melodies developed by the age of 6 years. It is noteworthy that only children who could categorize successfully showed a preference for tonality at the age of 6. For consonance, we observed an early preference for consonance at 4 years of age, but this preference was only measurable with large differences between consonant and dissonant stimuli. We propose that tonality and consonance preferences develop during childhood with increasing categorization ability when the surrounding musical culture is marked by Western tonality and consonance.

RESUMEN

The perception of two (or more) simultaneous musical notes, depending on their pitch interval(s), could be broadly categorized as consonant or dissonant. Previous literature has suggested that musicians and non-musicians adopt different strategies when discerning music intervals: while musicians rely on the frequency ratios between the two fundamental frequencies, such as "perfect fifth" (3:2) as consonant and "tritone" (45:32) as dissonant intervals; non-musicians may rely on the presence of 'roughness' or 'beats', generated by the difference of fundamental frequencies, as the key elements of 'dissonance'. The separate Event-Related Potential (ERP) differences in N1 and P2 along the midline electrodes provided evidence congruent with such 'separate reliances'. To replicate and to extend, in this study we reran the previous experiment, and separately collected fMRI data of the same protocol (with sparse sampling modifications). The behavioral and EEG results largely corresponded to our previous finding. The fMRI results, with the joint analyses by univariate, psycho-physiological interaction, and representational similarity analysis (RSA) approaches, further reinforce the involvement of central midline-related brain regions, such as ventromedial prefrontal and dorsal anterior cingulate cortex, in consonant/dissonance judgments. The final spatiotemporal searchlight RSA provided convincing evidence that the medial prefrontal cortex, along with the bilateral superior temporal cortex, is the joint locus of midline N1 and dorsal anterior cingulate cortex for the P2 effect (for musicians). Together, these analyses reaffirm that musicians rely more on experience-driven knowledge for consonance/dissonance perception; but also demonstrate the advantages of multiple analyses in constraining the findings from both EEG and fMRI.

RESUMEN

OBJECTIVE: The eating disorders field has been limited by a predominant focus on White, Western women, and there is growing recognition of the need to understand cross-cultural variation in key constructs (i.e., ideal body types). A transdisciplinary, cultural models approach systematizes the incorporation of an "emic" perspective (a culture's own understandings of phenomena) into assessments of relationships between body shapes and eating disorders. METHOD: Eighty-one young South Korean men aged 19-34 years living in Seoul participated in this research. A cultural model of body fatness was identified using cultural consensus analysis during 18 months of ethnographic, mixed-methods fieldwork. Participants also completed questionnaires assessing age, height, weight, sexual identity, university prestige, body dissatisfaction, eating disorder symptoms, and cultural consonance with the Korean cultural model of the ideal male body. Variation in these factors was analyzed using a series of chi-squares and analyses of variance with the culturally defined categories of body fatness as the independent variables. RESULTS: Cultural consensus analysis found that young South Korean men are consistent in identifying categories of "too thin," "balanced," and "too fat." The "balanced" category contained the lowest proportion of high-prestige university attendees and the highest average cultural consonance. The "too fat" category was characterized by the highest levels of body dissatisfaction and dieting, as well as proportion of probable eating disorders. DISCUSSION: A cultural models approach identified culturally important factors and patterns in disordered eating among young South Korean men and may be effective for understanding eating disorders in other populations not typically studied. PUBLIC SIGNIFICANCE: This study applies a systematic, "emic" perspective to young South Korean men's body ideals. Young Korean men share a cultural model of body fatness, and this model frames how they experience risk for eating disorders. This study demonstrates a method for incorporating culture into research on eating disorder risk.

RESUMEN

The relationship between culture and the individual is a central focus of social scientific research. This paper examines motivations that mediate between shared culture norms and individual actions. Inspired by the works of Leon Festinger and Melford Spiro, we posit that social network conformation (the perceived adherence of one's social network with norms) and internalization of cultural norms (incorporation of cultural models with the self-schema) will differentially shape behavior (cultural consonance) depending on the domain and individual characteristics. For the domain of gender roles among Brazilian men, religious affiliation results in different configurations of the individual and culture. Our findings suggest that, due to changing and competing cultural models, religious men are compelled to reflexively "think" about what masculinity means to them, rather than subconsciously conform to social (hegemonic) expectations. This study demonstrates the importance of considering the impetus of culturally informed behaviors and, in doing so, provides a methodological means for measuring and interpreting such motivations, an important factor in the relationship between culture and the individual.

RESUMEN

Objective: We examined the acculturation processes involving intergenerational consonance and dissonance in parent-child relationships in U.S. immigrant families. Background: This study is important because we lack national studies that examine the association between acculturation processes and intergenerational relationships among diverse racial/ethnic groups in immigrant families. Method: Using national data from Add Health with diverse race/ethnicity, we measured acculturation levels by immigrant generation, age of arrival, and length of time. Intergenerational consonance (the degree to which children and parents share the same values and activities) was measured by family cohesion and sharing meals (specifically dinners) with parents. Intergenerational dissonance (the degree to which parents and children differ in expected norms and parents lose authority over their children) was measured by parent-child conflict and parental control. Ordinary least square, binary logistic, ordered logistic, and Poisson regressions were conducted depending on the nature of the four dependent variables. Results: We found robust evidence that adolescents of the second immigrant generation acculturate more rapidly than those of the first generation and their immigrant parents creating a "gap" in intergenerational relationships. Thus, second-generation adolescents experience lower levels of family cohesion, less frequency of sharing weekly dinners with parents, less parental control of adolescents' activities, and more serious arguments about their behaviors with their parents than their first-generation counterparts. Conclusion: This is the new evidence that is based on national data, across multiple measures of intergenerational relationships, and holds for diverse racial and ethnic groups. Implications: The findings underscore the importance of developing culturally informed interventions supporting healthy parent-child relationships in immigrant families.

RESUMEN

Vehicular ad-hoc networks (VANETs) are increasingly pivotal for empowering applications in smart cities and intelligent traffic systems. However, the reliability and stability of VANET communications face formidable obstacles. Natura 2000 (N2k), the largest globally coordinated network of protected areas, has drawn significant criticism for its conservation-centric management structure lacking a strategic vision. This study proposes a three-phase strategy to address these concerns, aiming for effective and sustainable N2K site management. The novel approach employs DNN-Assisted Canonical Correlation Analysis (DNN-CCAS), encompassing cluster formation, cluster head selection, and outbreak recognition for enhanced VANET security. Vehicle clustering begins with an amended K-consonance method, emphasizing both position and speed through AKCEM clustering. A cluster head is chosen via a linear measure promenade approach, followed by secure data transmission to the cloud using DNN-CCAS if the cluster head is deemed normal. The proposed method outperforms prevailing techniques, achieving an impressive 91% accuracy. This comprehensive strategy not only addresses VANET communication challenges but also aims to revolutionize the management of N2K sites by integrating a strategic vision into conservation practices.

RESUMEN

Audio-visual correlation is a common phenomenon in real life. In this article, aiming at analyzing the correlation between multiple colors and combined tones, we comprehensively used experimental methods and technologies such as experimental psychology methods, audio-visual information processing technology, and machine learning algorithms to study the correlation mechanism between the multi-color perceptual attributes and the interval consonance attribute of musical sounds, so as to construct an audio-visual cross-modal matching models. Specifically, in the first, this article constructed the multi-color perceptual attribute dataset through the subjective evaluation experiment, namely "cold/warm," "soft/hard," "transparent/turbid," "far/near," "weak/strong," pleasure, arousal, and dominance; and constructed the interval consonance attribute dataset based on calculating the audio objective parameters. Secondly, a subjective evaluation experiment of cross-modal matching was designed and carried out for analyzing the audio-visual correlation, so as to obtain the cross-modal matched and mismatched data between the audio-visual perceptual attributes. On this basis, through visual processing and correlation analysis of the matched and mismatched data, this article proved that there is a certain correlation between multicolor and combined tones from the perspective of perceptual attributes. Finally, this article used linear and non-linear machine learning algorithms to construct audio-visual cross-modal matching models, so as to realize the mutual prediction between the audio-visual perceptual attributes, and the highest prediction accuracy is up to 79.1%. The contributions of our research are: (1) The cross-modal matched and mismatched dataset can provide basic data support for audio-visual cross-modal research; (2) The constructed audio-visual cross-modal matching models can provide a theoretical basis for audio-visual interaction technology; (3) In addition, the research method of audio-visual cross-modal matching proposed in this article can provide new research ideas for related research.

RESUMEN

Eating disorders are serious mental illnesses, but little research explores non-Western men's cultural experiences of body image and what affects their risks of disordered eating. Drawing on data collected over 17 months (August 2019 to January 2021) of fieldwork in Seoul, South Korea, the lens of intersectionality is employed alongside multiple regression and moderation analysis to understand how two axes of identity which emerged as important from the ethnography-sexual identity and university prestige-shape the ways in which young Korean men's cultural consonance with their local model of the ideal male body, influenced heavily by the kkonminam (flower boy), relates to risk for developing an eating disorder. Among young Korean men, intersections of university prestige and sexual identity frame embodiment of cultural models of male body image as a strategy for the making and maintenance of social relations and the advancement of social status in a precarious neoliberal economy.

RESUMEN

How do individuals rationalize the cognitive dissonance between their environmental awareness and the maintenance of environmentally unfriendly behaviors? The main goal is to explore the rationalization strategies used by individuals in order to maintain their current behaviors. The secondary goal is to understand if it is possible to induce cognitive consonance, and how this influences intention to change. We present a study (N = 222) with three experimental conditions: inconsistency, control, and consistency. The method to induce inconsistency and consistency was inspired by the paradigm of induced hypocrisy. Results demonstrated that induced inconsistency elicits two main barriers in participants: considering the change as unnecessary, and perceiving to lack knowledge about how to change. Induced consistency elicits tokenism, resulting in a licensing effect. However, behavioral intentions did not differ among experimental groups. Results are discussed considering methodological limitations and possible intervening variable.

RESUMEN

Roughness is a perceptual attribute typically associated with certain stimuli that are presented in one of the spatial senses. In auditory research, the term is typically used to describe the harsh effects that are induced by particular sound qualities (i.e., dissonance) and human/animal vocalizations (e.g., screams, distress cries). In the tactile domain, roughness is a crucial factor determining the perceptual features of a surface. The same feature can also be ascertained visually, by means of the extraction of pattern features that determine the haptic quality of surfaces, such as grain size and density. By contrast, the term roughness has rarely been applied to the description of those stimuli perceived via the chemical senses. In this review, we take a critical look at the putative meaning(s) of the term roughness, when used in both unisensory and multisensory contexts, in an attempt to answer two key questions: (1) Is the use of the term 'roughness' the same in each modality when considered individually? and (2) Do crossmodal correspondences involving roughness match distinct perceptual features or (at least on certain occasions) do they merely pick-up on an amodal property? We start by examining the use of the term in the auditory domain. Next, we summarize the ways in which the term roughness has been used in the literature on tactile and visual perception, and in the domain of olfaction and gustation. Then, we move on to the crossmodal context, reviewing the literature on the perception of roughness in the audiovisual, audiotactile, and auditory-gustatory/olfactory domains. Finally, we highlight some limitations of the reviewed literature and we outline a number of key directions for future empirical research in roughness perception.

RESUMEN

Group sequential design (GSD) is widely used in clinical trials in which correlated tests of multiple hypotheses are used. Multiple primary objectives resulting in tests with known correlations include evaluating (1) multiple experimental treatment arms, (2) multiple populations, (3) the combination of multiple arms and multiple populations, or (4) any asymptotically multivariate normal tests. In this paper, we focus on the first three of these and extend the framework of the weighted parametric multiple test procedure from fixed designs with a single analysis per objective to a GSD setting where different objectives may be assessed at the same or different times, each in a group sequential fashion. Pragmatic methods for design and analysis of weighted parametric group sequential design under closed testing procedures are proposed to maintain the strong control of the family-wise Type I error rate when correlations between tests are incorporated. This results in the ability to relax testing bounds compared to designs not fully adjusting for known correlations, increasing power, or allowing decreased sample size. We illustrate the proposed methods using clinical trial examples and conduct a simulation study to evaluate the operating characteristics.

RESUMEN

Mexican immigrants in the U.S. show high incidence of type 2 diabetes, and increased risk is associated with longer duration of residency. This study considers the impact of culture over time for Mexican immigrant women in a southern U.S. city. Using cultural consensus analysis to empirically derive the substance and structure of a cultural model for la buena vida (the good life) among Mexican immigrant women in Birmingham, Alabama, we assess the extent to which respondents are aligned with the model in their everyday lives. This measure of 'cultural consonance' is explored as a moderating variable between length of time living in the U.S. and level of Hemoglobin A1c. Results demonstrate that for those with more time in the U.S., those with lower consonance are more likely to have diabetes, while those who are more aligned with la buena vida are at lower risk.

RESUMEN

This study investigated the impact of value consonance on employee-based brand equity through the mediating role of teachers' self-efficacy and belongingness. For this purpose, a deductive approach was followed, and data were collected under a cross-sectional research design from academia through a questionnaire. Prior approval from the administration was sought before administrating the questionnaire on a large scale and a sample of 520 teachers was approached in the first phase. At this stage, 418 answered questionnaires were received, while in the second wave, questions related to the teacher's self-efficacy and employee-based brand equity were asked from the respondents. Out of these 418 re-distributed questionnaires, 387 were received back and after discarding the partially filled and incomplete questionnaires, the useable sample size was left as 372. Data have been analyzed by using the structural equation modeling technique, which was assessed through measurement and structural model. Results indicate that value consonance can promote positive behaviors in the workplace. Moreover, teachers with high self-efficacy can develop based on brand equity. Similarly, employees with high-value consonance develop a sense of belongingness with their academic institutes. Limitations and future directions are also discussed.

RESUMEN

Mexican-born women in the U.S. are at high risk of depression. While acculturation is the primary analytical framework used to study immigrant mental health, this research suffers from (1) a lack of specificity regarding how cultural models of living and being take shape among migrants converging in new destinations in the U.S., and (2) methods to empirically capture the impact of cultural positioning on individual health outcomes. Instead of relying on proxy measures of age at arrival and time in the U.S. to indicate where an individual is located on the acculturation spectrum, this study uses cultural consensus analysis to derive the substance and structure of a cultural model for la buena vida (the good life) among Mexican immigrant women in Birmingham, Alabama, and then assesses the extent to which respondents are aligned with the model in their everyday lives. This measure of 'cultural consonance' is explored as a moderating variable between age at arrival in the U.S. and number of depressive symptoms. Results demonstrate that for those who arrived at an older age, those with lower consonance are at the highest risk for depression, while those who are more aligned with la buena vida are at lower risk.

RESUMEN

Culture influences food consumption and nutrient intake. In this paper we present a new approach in research, examining how knowledge and understanding of food is encoded in cultural models. The degree to which individuals match these shared models in their own consumption patterns is then measured, using the concept of cultural consonance. In research conducted in urban Brazil, the configuration of cultural models of food, and the association of cultural consonance in food with nutrient intake, are moderated by socioeconomic status. The theory and method employed here offers a new approach to the study of culture, food, and nutrient intake.

RESUMEN

The perception of consonance and dissonance in intervals and chords is influenced by psychoacoustic and cultural factors. Past research has provided conflicting observations about the role of frequency in assessing musical consonance that may stem from comparisons of limited frequency bands without much theorizing or modeling. Here we examine the effect of register on perceptual consonance of chords. Based on two acoustic principles, we predict a decrease in consonance at low frequencies (roughness) and a decrease of consonance at high frequencies (sharpness). Due to these two separate principles, we hypothesize that frequency will have a curvilinear impact on consonance. A selection of tetrads varying in consonance were presented in seven registers spanning 30 to 2600 Hz. Fifty-five participants rated the stimuli in an online experiment. The effect of register on consonance ratings was clear and largely according to the predictions; The low registers impacted consonance negatively and the highest two registers also received significantly lower consonance ratings than the middle registers. The impact of register on consonance could be accurately described with a cubic relationship. Overall, the influence of roughness was more pronounced on consonance ratings than sharpness. Together, these findings clarify previous empirical efforts to model the effect of frequency on consonance through basic acoustic principles. They further suggest that a credible account of consonance and dissonance in music needs to incorporate register.

RESUMEN

Evidence supporting a link between harmoni-city and the attractiveness of simultaneous tone combinations has emerged from an experiment designed to mitigate effects of musical enculturation. I examine the analysis undertaken to produce this evidence and clarify its relation to an account of tonal aesthetics based on the biology of auditory-vocal communication.

RESUMEN

Possessing expert schemas is a positive feat that may yield different types of adaptive outcomes (e.g., informing procedural understanding that may result in a student skipping a few of the solution steps involved). Limited schemas, in contrast, may deter progress of a novice learner, limiting his/her capability to flourish. Taken as a whole, it may be concluded that expert schemas are more advantageous than novice schemas, differentiating learners in terms of expert and novice. Having said this, however, more recently, researchers have argued that possessing expert schemas could serve as deterrence. Recently, researchers have acknowledged a theoretical concept known as cognitive entrenchment, which is defined as a high level of stability in domain schemas. This description interestingly suggests that "entrenchment" or "situated fixation" of a course of action (e.g., a subject matter) could hinder the progress and learning experience of a person, namely-his/her inability and/or unwillingness to adapt to a new context, and/or his/her inflexibility and insistence to stay on course without any intent to change. One example of cognitive entrenchment is observed in professional football, wherein it has been argued that some football coaches are cognitively entrenched within their expert schemas, resulting in their demised game plans and strategic acumen. We advance the study of cognitive entrenchment by proposing an alternative viewpoint, which we term as the "perceived zone of certainty and uncertainty." This proposition counters the perspective of cognitive entrenchment by arguing that it is cognitive appraisal, judgment, mental resolute, and determination of a person in cognitive certainty of his/her success or failure, or the cognitive uncertainty of success or failure, that would explain the notion of inflexibility and/or unwillingness to adapt, and/or insistence to stay on course without any attempt to deviate. Moreover, we rationalize that certainty of success or failure would closely associate with a feeling of comfort, whereas uncertainty would associate with his/her feeling discomfort. In this analysis, we strongly believe that willingness to change and adapt, reluctance and insistence to remain on course, and/or inclination to embrace flexibility may not necessarily relate to the concept of cognitive entrenchment; rather, inflexibility and/or reluctance to change for the purpose of adaptation has more to do with the desire of a person to seek a state of comfort. Finally, our conceptual analysis of cognitive entrenchment also considers an interesting theoretical concept, which we termed as "perceived optimal efficiency." Perceived optimal efficiency, similar to cognitive relevance theory, is concerned with the relationship between minimum investment of time, effort, cognitive resources, etc., and an optimal best outcome. The issue for discussion, from our point of view, is related to the extent to which the certainty of success or failure would associate with perceived optimal efficiency.

RESUMEN

The majority of research in the field of music perception has been conducted with Western participants, and it has remained unclear which aspects of music perception are culture dependent, and which are universal. The current study compared how participants unfamiliar with Western music (people from the Khowar and Kalash tribes native to Northwest Pakistan with minimal exposure to Western music) perceive affect (positive versus negative) in musical chords compared with United Kingdom (UK) listeners, as well as the overall preference for these chords. The stimuli consisted of four distinct chord types (major, minor, augmented, and chromatic) and were played as both vertical blocks (pitches presented concurrently) and arpeggios (pitches presented successively). The results suggest that the Western listener major-positive minor-negative affective distinction is opposite for Northwest Pakistani listeners, arguably because of the reversed prevalence of these chords in the two music cultures. The aversion to the harsh dissonance of the chromatic cluster is present cross-culturally, but the preference for the consonance of the major triad varies between UK and Northwest Pakistani listeners, depending on cultural familiarity. Our findings imply not only notable cultural variation but also commonalities in chord perception across Western and non-Western listeners.
