Validation of the Goldsmiths Musical Sophistication Index in the Arab context: Results and implications of a Moroccan study

The Goldsmiths Musical Sophistication Index (Gold-MSI) is an extensively used self-report measure of musical skills and behaviours; however, to-date, no validated Arabic translation of the Gold MCI exists. This study reports on the Gold-MSI validation in the Moroccan setting. Our sample consisted of Moroccan adults (n = 660). Psychometric properties revealed good internal consistency (coefficient α = 0.93, the McDonald’s ω = 0.93, and Guttman’s Lambda = 0.95); and revealed a good fit: CFI = 0.83, RMSEA = 0.067, and SRMR = 0.068. The Arabic version of Gold-MSI appears a reliable and valid measure of musical skills and behaviours in the Moroccan setting.

The connection between disaggregate energy use and export sophistication: New insights from OECD with robust panel estimations

Numerous nations have demonstrated their commitment to achieve sustainable economic growth by enhancing export sophistication fueled by imperative energy utilization. This research examines the impact of renewable and non-renewable energy (RE and NRE) use on the improvement and diversification of export strategies among OECD economies using data from 1990 to 2022. This study contributes to the existing body of knowledge by introducing an export sophistication index as a dependent variable in the corresponding model. Pre-estimations followed by employing the CS-ARDL method findings revealed that disaggregated energy use plays a pivotal role in enhancing the intelligence of OECD economies, with the use of NRE energy exerting a more significant influence than REN use. While foreign direct investment, institutional quality and human capital also play essential roles in the complexity of exports within these economies. Applying the dynamic econometric technique, Wavelet coherence analysis substantiates these findings. Consequently, the study's results yield a range of policy recommendations.

Does increasing reliance on China help the North Korean economy? Evidence from export composition

ABSTRACT This Research Note suggests that reliance on China impedes the development of the North Korean economy. We conduct empirical analyzes using export structure, which is considered a significant predictor of economic growth potential. Using the export sophistication index, we find that increasing dependence on China has led to a qualitative decline in the composition of North Korean exports. This relationship is not attributable to economic sanctions, and our instrumental variable (IV) strategy further supports the causal interpretation of empirical evidence.

Music training is related to late ERP modulation and enhanced performance during Simon task but not Stroop task.

Increasing evidence suggests that music training correlates with better performance in tasks measuring executive function components including inhibitory control, working memory and selective attention. The Stroop and Simon tasks measure responses to congruent and incongruent information reflecting cognitive conflict resolution. However, there are more reports of a music-training advantage in the Simon than the Stroop task. Reports indicate that these tasks may differ in the timing of conflict resolution: the Stroop task might involve early sensory stage conflict resolution, while the Simon task may do so at a later motor output planning stage. We hypothesize that musical experience relates to conflict resolution at the late motor output stage rather than the early sensory stage. Behavioral responses, and event-related potentials (ERP) were measured in participants with varying musical experience during these tasks. It was hypothesized that musical experience correlates with better performance in the Simon but not the Stroop task, reflected in ERP components in the later stage of motor output processing in the Simon task. Participants were classified into high- and low-music training groups based on the Goldsmith Musical Sophistication Index. Electrical brain activity was recorded while they completed visual Stroop and Simon tasks. The high-music training group outperformed the low-music training group on the Simon, but not the Stroop task. Mean amplitude difference (incongruent-congruent trials) was greater for the high-music training group at N100 for midline central (Cz) and posterior (Pz) sites in the Simon task and midline central (Cz) and frontal (Fz) sites in the Stroop task, and at N450 at Cz and Pz in the Simon task. N450 difference peaks occurred earlier in the high-music training group at Pz. Differences between the groups at N100 indicate that music training may be related to better sensory discrimination. These differences were not related to better behavioral performance. Differences in N450 responses between the groups, particularly in regions encompassing the motor and parietal cortices, suggest a role of music training in action selection during response conflict situations. Overall, this supports the hypothesis that music training selectively enhances cognitive conflict resolution during late motor output planning stages.

Assessing fragility functions of unreinforced masonry buildings

The seismic vulnerability entrenched within the historical urban landscapes of Algeria serves as a poignant reminder of the pressing need for comprehensive risk management strategies, particularly concerning low and medium height unreinforced masonry (URM) structures. These architectural gems, rich in cultural significance, stand as tangible embodiments of Algeria's storied past. However, their susceptibility to seismic disturbances presents an immediate threat, demanding meticulous attention and innovative methodologies for effective risk assessment and mitigation. In a pioneering scholarly pursuit, this research embarks on an ambitious exploration, melding fragility functions and a sophisticated vulnerability index method to unravel the intricate tapestry of seismic risk assessment. Through the lens of fragility functions, the study delves into a nuanced analysis, probabilistically delineating the vulnerabilities entrenched within the complex framework of URM buildings. Furthermore, the meticulous derivation of vulnerability functions via the vulnerability index method enhances the granularity of risk assessment, providing a multifaceted perspective to discern vulnerabilities accurately. Central to this investigation is the Belouizdad district, a microcosm of historical significance nestled within the vibrant metropolis of Algiers. By scrutinizing seismic scenarios spanning a spectrum of intensities (ranging from VII to X), the study orchestrates a symphony of empirical data and analytical prowess, unraveling the potential seismic reverberations poised to impact the district's architectural heritage. In essence, this scholarly endeavor transcends the confines of mere academic pursuit, serving as a guiding light illuminating the path towards tailored seismic reduction policies. It stands as a clarion call to safeguard Algeria's architectural patrimony, fostering resilience amidst the tremors of uncertainty and ensuring the preservation of its cultural legacy for generations to come.

Audiovisual integration in the McGurk effect is impervious to music training.

The McGurk effect refers to an audiovisual speech illusion where the discrepant auditory and visual syllables produce a fused percept between the visual and auditory component. However, little is known about how individual differences contribute to the McGurk effect. Here, we examined whether music training experience-which involves audiovisual integration-can modulate the McGurk effect. Seventy-three participants completed the Goldsmiths Musical Sophistication Index (Gold-MSI) questionnaire to evaluate their music expertise on a continuous scale. Gold-MSI considers participants' daily-life exposure to music learning experiences (formal and informal), instead of merely classifying people into different groups according to how many years they have been trained in music. Participants were instructed to report, via a 3-alternative forced choice task, "what a person said": /Ba/, /Ga/ or /Da/. The experiment consisted of 96 audiovisual congruent trials and 96 audiovisual incongruent (McGurk) trials. We observed no significant correlations between the susceptibility of the McGurk effect and the different subscales of the Gold-MSI (active engagement, perceptual abilities, music training, singing abilities, emotion) or the general musical sophistication composite score. Together, these findings suggest that music training experience does not modulate audiovisual integration in speech as reflected by the McGurk effect.

The Danish Goldsmiths Musical Sophistication Index: Validation in Samples with Different Degrees of Representativeness

Convenience sampling is often used in music psychology research, leading to an overrepresentation of young participants with high socio-economic status and potentially compromising the generalizability of empirical findings to the broader population. Fortunately, analysis techniques enable matching biased samples to known population characteristics, for example, age, gender, and employment status. This study’s aim is twofold. First, we validate the Danish version of the Goldsmiths Musical Sophistication Index (Gold-MSI-da), a self-report inventory assessing various aspects of musical sophistication on continuous scales in the general population. Then, we demonstrate the use of stratification techniques and quantify the influence of sample composition by comparing results from analyses performed on our biased sample to similar analyses performed using stratified subsampling and poststratification weights to increase representativeness. The bifactor structure of the Gold-MSI-da was consistently replicated, showing similar subscale percentiles in three sample variants. Psychometric benchmarks of internal consistency aligned with benchmarks from other language versions, and although model fits were weaker in the most representative sample, they were still acceptable. Interestingly, the sizes of the effect of self-reported musical training and expertise on musical listening abilities diminished with increasing sample representativeness, indicating potential overestimation when relying on non-representative samples. We conclude that the Gold-MSI-da is a valid tool for assessing musical sophistication in the Danish general population.

Musical Training as a Continuum: Relationships of Short-Term Memory and Musical Aptitudes

ABSTRACT Introduction This study recruited participants from a range of music training experiences and focused on short-term memory tasks to examine the abilities of trained, informally trained, and those without any music training. Methods Musicianship was measured with the Goldsmith’s Musical Sophistication Index (GMSI). The GMSI is a survey regarding how music is involved in a participant’s daily life. Music training was assessed through the music training subscale of the GMSI, which included a question regarding the years of formal training an individual had received. In two objective measures of musical ability, participants completed the Computerized Adaptive Beat Alignment Test (CABAT) and the Melody Discrimination Test (MDT). The participants also completed an audio and audiovisual span task to measure short-term memory. A correlational analysis was run among the general score of the GMSI subjective task, the GMSI subscales, the span task scores, and the objective measures of musical ability. Lastly, a hierarchical regression was used to predict short-term memory abilities. Results Results of a partial correlation analysis, controlling for the music training subscale, showed that the melodic discrimination task was associated with short-term memory, however, rhythm scores were not. Discussion This study suggested that there is no distinct advantage of formal training over informal training when studying musicians’ memory performance. Future research can benefit from investigating the characteristics of the full sample of participants, and not treating those without formal training as a homogenous group, devoid of any musical abilities.

The adaptation and validation of the Goldsmiths Musical Sophistication Index (Gold-MSI) in Italian: The Gold-MSI-IT

The Goldsmiths Musical Sophistication Index (Gold-MSI) measures a wide range of self-reported musical abilities and behaviors in the Western adult general population, regardless of musical expertise. This instrument has been validated in various languages, but an Italian version is lacking. The present study describes the Italian validation and adaptation of the Gold-MSI (Gold-MSI-IT) and investigates the effects of socio-demographic variables on scores of musical sophistication. Analyses of factor structure and internal reliability on an Italian sample ( N = 429, mean age = 31.08, SD = 11.68, 75.5% female) and analyses of test–retest reliability on a smaller sample ( N = 57, mean age = 34.68, SD = 10.80, 75% female) show that the Gold-MSI-IT conforms to a bifactor model, similarly to the original version, including an underlying General Musical Sophistication factor and five subfactors, and that our instrument has good internal consistency and good test–retest reliability. Additional tests showed gender differences in musical sophistication and that musical sophistication correlated with education but not with age. The study provides a reliable and stable tool to investigate individual differences in the Italian context and adds to our knowledge of musicality in the general population across countries.

23 Musical Training May Not Enhance Cognitive-Motor Integration in Healthy Young Adults

Objective:Hand and arm functions have been associated with cognition in healthy young and older adults (Vasylenko et al., 2018) and in patients with Parkinson's disease (Bezdicek et al., 2014). Music training has been proposed to integrate motor and cognitive functions by engaging motoric, sensory, perceptual, and various cognitive domains (Wan & Schlaug, 2010). In this study, we examined if performance on fine and gross motor tasks is predicted by cognitive measures of memory, attention, and executive functions, and whether this relationship varies by the extent of musical training in healthy young participants.Participants and Methods:Forty five healthy young participants were recruited (M = 22.32, SD = 4.10; 78% female). Participants completed fine (Grooved pegboard) and gross motor (Box and Blocks) measures as well as cognitive measures (Rey auditory verbal learning test, Stroop, Trail making, and D2 cancellation), and the musical training subscale of the Goldsmith Musical Sophistication Index. Two multiple regression models were conducted assessing cognitive measures as predictors of fine and gross motor functions, with musical training as a covariate in both models.Results:Musical training was normally distributed across participants (M = 23.47, SD = 10.28). The results of the first model assessing the role of cognitive measures as predictors of fine motor function indicate a moderate fit (F(5,36) = 3.32, R = 0.55, explaining .32 of variance, p < .05), with memory (B = 2.75, SE = 0.82, p < .005) and sustained attention (B = 0.09, SE = 0.03, p < .01) as moderate predictors. These cognitive measures were also found to predict gross motor function (F(5,36) = 3.06, p < .05, R = 0.55, explaining .30 of the variance), with memory retention (B = 2.49, SE = 0.83, p < .001) and sustained attention (B = 0.07, SE = 0.03, p < .05) as moderate predictors. In both models, musical training was not a significant predictor.Conclusions:We found that both fine and gross hand motor functions are predicted by cognitive measures of memory retention and sustained attention. Our results support previous findings associating cognition and motor function, with attention being relevant in young adults and memory a predictor in older adults (Vasylenko et al., 2018). We corroborate these findings for hand function, but did not find executive functions to be implicated, which were previously reported as a predictor only for older adults. While musical training has been suggested to enhance the cognitive-motor relationship as it involves motor skills as well as engages various cognitive domains (Wan & Schlaug, 2010), prior musical training was not found to affect this relationship. While music background did not predict better hand motor function, it did account for more interpersonal variance. The results suggest that for most amateur musicians, including those with years of experience, musical training may not affect the association between cognition and both fine and gross hand motor skill. The current findings indicate that while musical training can be an enriching experience, it may not (exclusively) enhance motor-cognitive integration. Different outcomes may be found with more extreme levels of music training, or a different age group.

Analysis of heatwaves based on the universal thermal climate index and apparent temperature over mainland Southeast Asia.

Heatwaves have caused significant damage to human health, infrastructure, and economies in recent decades, and the occurrences of heatwaves are becoming more frequent and severe across the globe under climate change. The previous studies on heatwaves have primarily focused on air temperature, neglecting other variables like wind speed, relative humidity, and radiation, which could lead to a serious underestimation of the adverse effects of heatwaves. To address this issue, this study proposed to the use of more sophisticated thermal indices, such as universal thermal climate index (UTCI) and apparent temperature (AT), to define heatwaves and carry out a comprehensive heatwave assessment over mainland southeast Asia (MSEA) from 1961 to 2020. The traditional temperature-based method was also compared. The results of the study demonstrate that the annual maximum temperature in heatwave days (HWA) and the annual average temperature in heatwave days (HWM) are significantly underestimated if only air temperature is considered. However, UTCI and AT tend to predict a lower frequency of yearly heatwave occurrences and shorter durations. Trend analysis indicates a general increase in heatwave occurrences across MSEA under all thermal indices in the past six decades, particularly in the last 30years. This study's approach and findings provide a holistic view of heatwave characteristics based on thermal indices and highlight the risk of intensified heat stress during heatwaves in MSEA.

Pathophysiological discussions and statistical results between diabetes caused by obesity versus cancers caused by obesity via SD-VMT areas comparison using data collected from 2010 to 2023 and based on space-domain viscoplastic energy model of GH-Method: Math-Physical Medicine (No. 893, VGT #293)

The objective of this methodology article is to assess and compare the risks of developing type 2 diabetes (T2D) and cancers caused by obesity as a single input factor. The study spans a timeframe of approximately 14 years, from 2010 to 2023. The author personally collected and analyzed their input data, although there were limitations in obtaining sufficient lab-tested data between 2010 and 2012. From 2013 to 2018, the data collection methods involved more lab testing and personal data obtained through finger-piercing glucose testing. A more complete and comprehensive dataset was obtained from 2018 to 2023, utilizing laboratory tests, automated glucose sensors, and wearable health devices. Despite these limitations, the annual dataset used in this study is considered adequate for drawing useful and reasonably accurate conclusions. The author has been diagnosed with T2D since 1996 but has not received any cancer diagnoses. The assessment of cancer risk in this study is conducted using a sophisticated metabolism index (MI) model developed by the author in 2014. This model takes into account factors such as lifetime bad habits, environmental factors, genetic concerns, four metabolic disorders, and six lifestyle details. To analyze and compare the contribution of T2D (measured through HbA1C levels) and cancer risks based on the single input cause of obesity (measured through body weight, m1), this study utilizes the space-domain viscoplastic energy model from GH-Method: Math-Physical Medicine. In summary, this research presents two key findings: Firstly, the author conducts two separate analyses to evaluate the impact of obesity on his existing T2D condition and his future risks of developing cancer. The SD-VMT analysis shows that the energy level for T2D and obesity is 110.1, while the energy level for cancers and obesity is only 1.18, representing just 1% of the diabetes energy level. This finding indicates that despite being a T2D veteran of 26 years, the author has not shown any signs of developing cancer. Furthermore, his SD time-zone analysis reveals that 98% of the total energy is concentrated in the Y10-Y13 for T2D and Y10-Y17 for cancers, while only 2% falls in the Y14-Y23 for T2D and Y18-Y23 for cancers. Secondly, as an exploratory medical research methodology, he considers obesity as the output symptom, with diabetes and cancers being two separate input causes. The SD-VMT energy ratios demonstrate that diabetes accounts for 69% of the total energy, while cancers account for 31%. Although diabetes has twice as much energy as cancers, the disparity is not as substantial as the 99-fold difference observed in the first case. This finding emphasizes that the author's existing diabetes condition is significantly more severe than his risks of developing cancer.

Effects of musical mnemonics on working memory performance in cognitively unimpaired older adults and persons with amnestic mild cognitive impairment.

Episodic memory (EM) and working memory (WM) are negatively affected by healthy ageing, and additional memory impairment typically occurs in clinical ageing-related conditions such as amnestic mild cognitive impairment (aMCI). Recent studies on musical mnemonics in Alzheimer's dementia (AD) showed promising results on EM performance. However, the effects of musical mnemonics on WM performance have not yet been studied in (a)MCI or AD. Particularly in (a)MCI the use of musical mnemonics may benefit the optimisation of (working) memory performance. Therefore, in the present study, we examined the effects of musical presentation of digits consisting of pre-recorded rhythms, sung unfamiliar pitch sequences, and their combinations, as compared to spoken presentation. Furthermore, musical expertise was assessed with two perceptual tests and the Self-Report Inventory of the Goldsmiths Musical Sophistication Index. Thirty-two persons with aMCI and 32 cognitively unimpaired older adults (OA) participated in this study. Confirming and extending previous findings in research on ageing, our results show a facilitating effect of rhythm in both cognitively unimpaired OA and persons with aMCI (p = .001, ηp 2 = .158). Furthermore, pitch (p = .048, ηp 2 = .062) and melody (p = .012, ηp 2 = .098) negatively affected performance in both groups. Musical expertise increased this beneficial effect of musical mnemonics (p = .021, ηp 2 = .090). Implications for the future design of music-based memorisation strategies in (a)MCI are discussed.

Measuring musical sophistication in the Chinese general population: Validation and replication of the Simplified Chinese Gold-MSI

The Goldsmiths Musical Sophistication Index has been translated into several European languages. In the East Asian area, a traditional Chinese language translation is available. Due to differences in written characters and language use in various Chinese regions, a translation using simplified Chinese would reach a wider audience in mainland China and other regions. Our study, therefore, aimed to validate the simplified Chinese version of the Gold-MSI (Gold-MSI-SC) to replicate psychometric properties and factor structures of the Gold-MSI and to investigate the relationship between socioeconomic status (SES) and factors of the Gold-MSI-SC in a mainland Chinese sample ( N = 64,555). Following the translation guidelines for intercultural research, the Gold-MSI-SC self-report questionnaire, two music listening tests, and the Musical-Rhythmic Intelligence subscale (M-RI) were included in the main study together with the demographic and SES-related questions. All subscales of the Gold-MSI-SC showed high internal consistency (Cronbachs’ ɑ = [.80–.91]) and good test-retest reliability ( rtt = [.842–.935]). Confirmatory factor analysis revealed that the original bi-factor structure was replicated with satisfactory fit (root mean square error of approximation (RMSEA) = .053 and comparative fit index (CFI) = .888). Correlations between the Gold-MSI-SC and the music tests, as well as the M-RI, demonstrated strong convergent and discriminant validity; structural equation models revealed negative relationships between age and the Gold-MSI factors, while SES positively correlated with all of the subscales. The Gold-MSI-SC has thus been shown to be a reliable tool in assessing multidimensional musical behaviors in simplified Chinese and in supporting the measurability of musical sophistication in different cultures.

Additive extensive reading and syntactic development in second language writing: Analyses of syntactic complexity and sophistication in young EFL learners’ book reports

This study explores how input-driven activity through extensive reading leads to syntactic growth in young students’ written production. Twenty-six young students learning English as a foreign language participated in extensive reading as an additional activity after school for a month (ER group), and their syntactic development was inspected by analyzing 14 syntactic complexity and six syntactic sophistication indices in the students’ book reports written preceding and following the reading activity. This group’s performance in writing was compared with that of another group of students who did not participate in the reading activity (Comparison group). Results of analyses for syntactic complexity showed that the ER group significantly improved in the length of sentence, the number of clauses, the number of coordination, and the number of verb phrases. This group also improved in syntactic sophistication by using less frequent verbs and less frequent verb-construction combinations in writing after the reading activity. In contrast, the comparison group showed improvements only in the length of sentence. We discuss these findings and pedagogical implications in light of usage-based approaches to language learning.

Emotional valence perception in music and subjective arousal: Experimental validation of stimuli.

Musical stimuli are widely used in emotion research and intervention studies. However, reviews have repeatedly noted that a lack of pre-evaluated musical stimuli is stalling progress in our understanding of specific effects of varying music. Musical stimuli vary along a plethora of dimensions. Of particular interest are emotional valence and tempo. Thus, we aimed to evaluate the emotional valence of a set of slow and fast musical stimuli. N = 102 (mean age: 39.95, SD: 13.60, 61% female) participants rated the perceived emotional valence in 20 fast (>110 beats per minute [bmp]) and 20 slow (<90 bpm) stimuli. Moreover, we collected reports on subjective arousal for each stimulus to explore arousal's association with tempo and valence. Finally, participants completed questionnaires on demographics, mood (profile of mood states), personality (10-item personality index), musical sophistication (Gold-music sophistication index), and sound preferences and hearing habits (sound preference and hearing habits questionnaire). Using mixed-effect model estimates, we identified 19 stimuli that participants rated to have positive valence and 16 stimuli that they rated to have negative valence. Higher age predicted more positive valence ratings across stimuli. Higher tempo and more extreme valence ratings were each associated with higher arousal. Higher educational attainment was also associated with higher arousal reports. Pre-evaluated stimuli can be used in future musical research.

Replication of the music preference (MUSIC) model and evaluation of its association with personality and autistic traits

Music preferences have consistently been found to follow a five-factor structure (i.e., Mellow, Unpretentious, Sophisticated, Intense, and Contemporary, in short MUSIC), in the West. These factors are associated, in turn, with the Big Five personality traits. However, the stability of this structure and its association with personality in non-Western cultures are underexplored. Moreover, behavioral traits other than personality traits might relate to music preferences. High systemizing traits, as often seen in people with autism, tend to be associated with a preference for Intense music. However, whether this generalizes to autistic traits in the general population remains unclear. The current study therefore attempted to examine the five-factor MUSIC model and test its association with Big Five personality traits and autistic traits in an online study of Malaysians. A total of 444 participants, of whom 59.7% were of Chinese ethnicity, rated their preference for 50 brief musical excerpts and completed the Ollen Musical Sophistication Index, the Ten-Item Personality Inventory, and the Autism-Spectrum Quotient-28. The original MUSIC model was partially replicated with virtually identical Sophisticated and Intense factors. However, once age, gender, and musical sophistication were controlled for, most of the previously reported associations between Big Five personality traits and music preferences were not found. Instead of a positive association between autistic traits and Intense music, a negative association was found between autistic traits and Contemporary music. These findings partially support the validity of the MUSIC model in Malaysia and highlight the importance of undertaking research on music preferences in non-Western contexts.

Green Innovation for Competitiveness: Impact on GDP Growth in the European Union

Since the start of the Industrial Revolution, the global climate has changed dramatically. Concentrations of greenhouse gases (GHGs) in the atmosphere have increased sharply, followed by an increase in global average temperatures. However, business activities related to environmental protection are mostly focused on the implementation of legal rules instead of voluntary initiatives such as green innovation due to doubts about costs and profit. The goal of this research is to identify the impact of green innovation on economic growth in an innovative environment and digitalization conditions by using sophisticated indexes and regression analysis. The results show that green innovations have a positive impact on economic growth in the European Union (EU). However, the impact of digitalization on economic growth is still under discussion and depends on qualitative aspects of coverage and how they are reflected in digitalization indicators. It is important to emphasize that the data of this empirical study only cover EU countries that are subject to EU regulation and have similar trends in the development and diffusion of green innovations. Non-EU countries may have different approaches and policies influencing the maturity and diffusion of green innovations. The results of this research provide a scientific basis for strategic planning at the national and business levels, encouraging a focus on the development of green innovation not only as a means of reducing the impact of climate change but also as a strategic direction for increasing competitiveness and economic growth.
