Musical Aptitude as a Variable in the Assessment of Working Memory and Selective Attention Tasks

Background and Objectives: The influence of musical aptitude on cognitive test performance in musicians is a long-debated research question. Evidence points to the low performance of nonmusicians in visual and auditory cognitive tasks (working memory and attention) compared with musicians. This cannot be generalized to all nonmusicians, as a sub-group in this population can have innate musical abilities even without any formal musical training. The present study aimed to study the effect of musical aptitude on the working memory and selective attention.Subjects and Methods: Three groups of 20 individuals each (a total of 60 participants), including trained-musicians, nonmusicians with good musical aptitude, and nonmusicians with low musical aptitude, participated in the present study. Cognitive-based visual (Flanker’s selective attention test) and auditory (working memory tests: backward digit span and operation span) tests were administered.Results: MANOVA (followed by ANOVA) revealed a benefit of musicianship and musical aptitude on backward digit span and Flanker’s reaction time (p<0.05). Discriminant function analyses showed that the groups could be effectively (accuracy, 80%) segregated based on the backward digit span and Flanker’s selective attention test. Trained musicians and nonmusicians with good musical aptitude were distinguished as one cluster and nonmusicians with low musical aptitude formed another cluster, hinting the role of musical aptitude in working memory and selective attention.Conclusions: Nonmusicians with good musical aptitude can have enhanced working memory and selective attention skills like musicians. Hence, caution is required when these individuals are included as controls in cognitive-based visual and auditory experiments.

The Relationship between Musical Aptitude, Self-efficacy and Achievement of Elementary School Pre-service Teachers

The primary purpose of this study was to examine the self-efficacy of pre-primary teachers for musical aptitude, such as pitch and rhythm, and to examine whether there is a significant change in self-efficacy through individual practice and instruction of Chorubungen exercises for eight weeks. Another purpose of the study was to examine the relationship between the musical experience and musicality of pre-service teachers, and their musical experience and achievement. To this end, a survey was conducted at the end of the semester for first-year students (56 males, 84 females) of a University of Education after regular individual practice in and guidance for eight weeks in the second semester of 2020. According to the results of the analysis, the positive self-efficacy of the pre-service teachers for pitch and rhythm before class participation was about 22.1% and 34.3% of the respondents, respectively, but after participating in the class, self-efficacy increased to 82.1% for pitch and 72.9% for rhythm. In comparison with the lower five variables, namely whether they learned an instrument among musical experiences (t-test) and the degree of singing (F test), pitch sensitivity (t=2.41, p<.05), rhythm sensitivity (t =1.98, p<.05), tempo sensitivity (t=2.79, p<.01), major scale, and major harmony pattern sensitivity (t=2.67, p<.01), all showed significant differences. In comparison to the achievement groups (chi-square test), differences between the achievement groups were measured based on whether they previously had experienced musical instruments (χ2=10.11, p<.01) and whether they had been active in a club (χ2=8.70, p<.05).

The Effect of Musical Stimulation and Mother’s Voice on the Early Development of Musical Abilities: A Neuropsychological Perspective

An infant’s early contact with music affects its future development in a broad sense, including the development of musical aptitude. Contact with the mother’s voice, both prenatally and after birth, is also extremely important for creating an emotional bond between the infant and the mother. This article discusses the role that auditory experience—both typically musical and that associated with the mother’s voice—plays in fetal, neonatal, and infant development, particularly in terms of musical aptitude. Attempts have also been made to elucidate the neuropsychological mechanisms underlying the positive effects that appropriate musical stimulation can have on a child’s development.

The Melody of Speech: What the Melodic Perception of Speech Reveals about Language Performance and Musical Abilities

Research has shown that melody not only plays a crucial role in music but also in language acquisition processes. Evidence has been provided that melody helps in retrieving, remembering, and memorizing new language material, while relatively little is known about whether individuals who perceive speech as more melodic than others also benefit in the acquisition of oral languages. In this investigation, we wanted to show which impact the subjective melodic perception of speech has on the pronunciation of unfamiliar foreign languages. We tested 86 participants for how melodic they perceived five unfamiliar languages, for their ability to repeat and pronounce the respective five languages, for their musical abilities, and for their short-term memory (STM). The results revealed that 59 percent of the variance in the language pronunciation tasks could be explained by five predictors: the number of foreign languages spoken, short-term memory capacity, tonal aptitude, melodic singing ability, and how melodic the languages appeared to the participants. Group comparisons showed that individuals who perceived languages as more melodic performed significantly better in all language tasks than those who did not. However, even though we expected musical measures to be related to the melodic perception of foreign languages, we could only detect some correlations to rhythmical and tonal musical aptitude. Overall, the findings of this investigation add a new dimension to language research, which shows that individuals who perceive natural languages to be more melodic than others also retrieve and pronounce utterances more accurately.

Individual Differences in Perception of the Speech-to-Song Illusion are Linked to Musical Aptitude but not Musical Experience

In the speech-to-song illusion certain spoken phrases are perceived as sung after repetition. Prior work has established that perception of the illusion is not limited to specialist listeners, such as individuals with musical training, but is perceived widely across the general population. However, little is known about whether there are stable individual differences in perception of the illusion, and if so, what factors underlie this variability. Here we assessed the strength of the song illusion across individuals using phrases that tend to be perceived as song when repeated, as well as phrases that continue to be perceived as speech when repeated, measuring the strength of the illusion as the rating difference between these two stimulus categories after repetition. Illusion strength varied widely, with differences in perception of the two categories ranging from 0% to 80% of the rating scale. Although variability in illusion strength was unrelated to degree of musical training, participants who perceived the illusion more strongly were proficient in several musical skills, including beat perception, tonality perception, and selective attention to pitch. This finding supports theoretical models of the speech-to-song illusion in which experience of the illusion is based on detection of musical characteristics latent in spoken phrases.

Human Genomics and the Biocultural Origin of Music

Music is an exclusive feature of humankind. It can be considered as a form of universal communication, only partly comparable to the vocalizations of songbirds. Many trends of research in this field try to address music origins, as well as the genetic bases of musicality. On one hand, several hypotheses have been made on the evolution of music and its role, but there is still debate, and comparative studies suggest a gradual evolution of some abilities underlying musicality in primates. On the other hand, genome-wide studies highlight several genes associated with musical aptitude, confirming a genetic basis for different musical skills which humans show. Moreover, some genes associated with musicality are involved also in singing and song learning in songbirds, suggesting a likely evolutionary convergence between humans and songbirds. This comprehensive review aims at presenting the concept of music as a sociocultural manifestation within the current debate about its biocultural origin and evolutionary function, in the context of the most recent discoveries related to the cross-species genetics of musical production and perception.

The Contribution of Individual Differences to L2 Pronunciation Learning: Insights from Research and Pedagogical Implications

Adult second language (L2) learning often exhibits great variability in its rate and outcome. Although research shows that learning trajectories are partly shaped by social and contextual factors (e.g. Larson-Hall, 2008), certain learner factors play an important role in enhancing L2 pronunciation learning by helping L2 learners notice and process input efficiently, whereas certain learner factors may impede L2 pronunciation learning by impairing attention control or slowing down L2 input processing. Therefore, in order for language teachers to provide effective instruction and help students improve their L2 pronunciation proficiency, it is beneficial for them to understand the differential impact of learner characteristics on L2 learning and adapt such understanding to their instruction and learning activities. The aim of the current article is to provide a review of existing studies that have explored individual differences (IDs) in relation to L2 pronunciation acquisition and to present implications for effective L2 pronunciation teaching. The article begins with an introduction of the paradigm shift in L2 pronunciation research and the conceptual framework of IDs proposed by Dörnyei (2009). This is followed by a summary of the processes involved in L2 pronunciation learning. The third section focuses on the characteristics of four IDs that have been found to influence the development of L2 pronunciation. Those IDs include foreign language learning aptitude (e.g. Saito and Hanzawa, 2016), musical aptitude (e.g. Milovanov et al., 2010), L2 learning motivation (e.g. Moyer, 1999), and anxiety (e.g. Baran-Łucarz, 2016). Based on the discussion in the third section, the last section will offer various applications of IDs research findings to L2 pronunciation instruction (e.g. instructional approaches, feedback, and pronunciation syllabi) for successful L2 pronunciation teaching.
