Individual Differences in Singing Behavior during Childhood Predicts Language Performance during Adulthood

Misjudgement of One's Own Performance? Exploring Attention Deficit (Hyperactivity) Disorder (ADHD) and Individual Difference in Complex Music and Foreign Language Perception

In previous research, we detected that children and adolescents who were diagnosed with ADHD showed deficits in both complex auditory processing of musical stimuli and in musical performance when compared to controls. In this study, we were interested in whether we could detect similar or distinct findings when we use foreign speech perception tasks. Therefore, we recruited musically naïve participants (n = 25), music-educated participants (n = 25) and participants diagnosed with ADHD (n = 25) who were assessed for their short-term memory (STM) capacity and the ability to discriminate music and speech stimuli and we collected self-ratings of the participants' music and language performances. As expected, we found that young adults with ADHD show deficits in the perception of complex music and difficult speech perception stimuli. We also found that STM capacity was not impaired in young adults with ADHD and may not persist into young adulthood. In addition, subjective self-estimation about the participants' language and music performances revealed that the ADHD group overestimated their performance competence relatively compared to both control groups. As a result, the findings of our study suggest that individuals diagnosed with ADHD require a special training program that not only focuses on improving performance in perceptual skills of music and language but also requires metacognitive training to develop realistic self-assessment skills.

What Makes a Foreign Language Intelligible? An Examination of the Impact of Musical Ability and Individual Differences on Language Perception and How Intelligible Foreign Languages Appear

Previous research suggests that musical ability is associated with language processing and foreign language pronunciation. Whether musical ability is associated with the ability to generate intelligible unfamiliar utterances has not been investigated. Furthermore, how unfamiliar languages are perceived has rarely been related to musical ability. We tested 80 healthy adults, with a mean age of 34.05 and a combination of 41 women and 39 men. We used batteries of perceptual and generational music and language measures to assess foreign language intelligibility and musical capacity. Regression analysis revealed that five measures explained the variance in the intelligibility of unfamiliar foreign utterances. These were short-term memory capacity, melodic singing ability, speech perception ability, and how melodic and memorable the utterances sounded to the participants. Correlational analyses revealed that musical aptitude measures are related to melodic perception and how memorable unfamiliar utterances sound, whereas singing aptitude is related to the perceived difficulty level of the language material. These findings provide novel evidence of the link between musical and speech abilities. In particular, intelligibility measures are associated with singing aptitude and how melodic languages appear to be. As impressions on how foreign languages are perceived are also related to musical capacities, perceptual language parameters address a new perspective that facilitates the understanding of the link between music and language in general.

Singing ability is related to vocal emotion recognition: Evidence for shared sensorimotor processing across speech and music

The ability to recognize emotion in speech is a critical skill for social communication. Motivated by previous work that has shown that vocal emotion recognition accuracy varies by musical ability, the current study addressed this relationship using a behavioral measure of musical ability (i.e., singing) that relies on the same effector system used for vocal prosody production. In the current study, participants completed a musical production task that involved singing four-note novel melodies. To measure pitch perception, we used a simple pitch discrimination task in which participants indicated whether a target pitch was higher or lower than a comparison pitch. We also used self-report measures to address language and musical background. We report that singing ability, but not self-reported musical experience nor pitch discrimination ability, was a unique predictor of vocal emotion recognition accuracy. These results support a relationship between processes involved in vocal production and vocal perception, and suggest that sensorimotor processing of the vocal system is recruited for processing vocal prosody.

Singing Mandarin? What Short-Term Memory Capacity, Basic Auditory Skills, and Musical and Singing Abilities Reveal About Learning Mandarin

Learning Mandarin has become increasingly important in the Western world but is rather difficult to be learnt by speakers of non-tone languages. Since tone language learning requires very precise tonal ability, we set out to test whether musical skills, musical status, singing ability, singing behavior during childhood, basic auditory skills, and short-term memory ability contribute to individual differences in Mandarin performance. Therefore, we developed Mandarin tone discrimination and pronunciation tasks to assess individual differences in adult participants’ (N = 109) tone language ability. Results revealed that short-term memory capacity, singing ability, pitch perception preferences, and tone frequency (high vs. low tones) were the most important predictors, which explained individual differences in the Mandarin performances of our participants. Therefore, it can be concluded that training of basic auditory skills, musical training including singing should be integrated in the educational setting for speakers of non-tone languages who learn tone languages such as Mandarin.

Examining Individual Differences in Singing, Musical and Tone Language Ability in Adolescents and Young Adults with Dyslexia

In recent years, evidence has been provided that individuals with dyslexia show alterations in the anatomy and function of the auditory cortex. Dyslexia is considered to be a learning disability that affects the development of music and language capacity. We set out to test adolescents and young adults with dyslexia and controls (N = 52) for their neurophysiological differences by investigating the auditory evoked P1–N1–P2 complex. In addition, we assessed their ability in Mandarin, in singing, their musical talent and their individual differences in elementary auditory skills. A discriminant analysis of magnetencephalography (MEG) revealed that individuals with dyslexia showed prolonged latencies in P1, N1, and P2 responses. A correlational analysis between MEG and behavioral variables revealed that Mandarin syllable tone recognition, singing ability and musical aptitude (AMMA) correlated with P1, N1, and P2 latencies, respectively, while Mandarin pronunciation was only associated with N1 latency. The main findings of this study indicate that the earlier P1, N1, and P2 latencies, the better is the singing, the musical aptitude, and the ability to link Mandarin syllable tones to their corresponding syllables. We suggest that this study provides additional evidence that dyslexia can be understood as an auditory and sensory processing deficit.
