“…This results go in line with a developmental perspective of cortical tracking were delta CT relevance is larger during infancy and prereading stages (Attaheri et al, 2020). This could respond to the fact that spectral energy in the delta band is larger in child directed speech than in adult directed speech (Pérez-Navarro et al, 2022).…”

The precision of cortical tracking of auditory rhythmic stimuli in low frequency ranges coding for prosodic (delta) and syllabic (theta) amplitude modulations in the speech signal has been proposed to contribute to the development of phonological processing and reading acquisition. The present study investigates the role of low frequency cortical tracking of non-verbal auditory stimuli in reading acquisition through a longitudinal design from before the onset of formal reading instruction until one year afterwards. At time one, 40 prereading children performed a passive listening task of amplitude modulated white noise presented in the delta (2 Hz) and theta (4 Hz) frequency bands, while their neural activity was recorded via EEG. At time two, at the end of first grade, children’s reading skills were assessed. Results show significant cortical tracking in prereading children at both frequencies, with larger responses for theta than for delta rate non-verbal auditory stimuli. Importantly, only pre-reding cortical tracking measures for delta rate stimuli predicted reading acquisition one year later. These findings underscore the role of early neural synchronization to delta rate rhythmic auditory stimuli to reading acquisition and support the potential important role of early prosodic processing for the development of future reading skills.

“…Further, another study comparing the hierarchical rhythmic structure across various types of sounds (nature, speech, instrumental music, song, animal sounds, etc.) has demonstrated that the slower band hierarchy (< 3 Hz) is especially pronounced in children's songs and infant/child-directed speech compared to other types of sounds 19 and across different cultures 30 . Thus, auditory stimuli directed towards children commonly exhibit a stronger power of slow rhythms.…”

“…has demonstrated that the slower band hierarchy (i.e. 1–3 Hz) is especially pronounced in children's songs and speech directed towards infants and children (referred to as infant/child-directed speech) compared to other types of sounds 19 and in at least one other culture 30 . Further, evidence has shown that the infant is first phase-entrained to the slower rhythm (1–3 Hz) in infant-directed speech 31 , suggesting that such a slower-band rhythm is important for early learning of language and music.…”

Statistical learning is thought to be linked to brain development. For example, statistical learning of language and music starts at an early age and is shown to play a significant role in acquiring the delta-band rhythm that is essential for language and music learning. However, it remains unclear how auditory cultural differences affect the statistical learning process and the resulting probabilistic and acoustic knowledge acquired through it. This study examined how children’s songs are acquired through statistical learning. This study used a Hierarchical Bayesian statistical learning (HBSL) model, mimicking the statistical learning processes of the brain. Using this model, I conducted a simulation experiment to visualize the temporal dynamics of perception and production processes through statistical learning among different cultures. The model learned from a corpus of children’s songs in MIDI format, which consists of English, German, Spanish, Japanese, and Korean songs as the training data. In this study, I investigated how the probability distribution of the model is transformed over 15 trials of learning in each song. Furthermore, using the probability distribution of each model over 15 trials of learning each song, new songs were probabilistically generated. The results suggested that, in learning processes, chunking and hierarchical knowledge increased gradually through 15 rounds of statistical learning for each piece of children’s songs. In production processes, statistical learning led to the gradual increase of delta-band rhythm (1–3 Hz). Furthermore, by combining the acquired chunks and hierarchy through statistical learning, statistically novel music was generated gradually in comparison to the original songs (i.e. the training songs). These findings were observed consistently, in multiple cultures. The present study indicated that the statistical learning capacity of the brain, in multiple cultures, contributes to the acquisition and generation of delta-band rhythm, which is critical for acquiring language and music. It is suggested that cultural differences may not significantly modulate the statistical learning effects since statistical learning and slower rhythm processing are both essential functions in the human brain across cultures. Furthermore, statistical learning of children’s songs leads to the acquisition of hierarchical knowledge and the ability to generate novel music. This study may provide a novel perspective on the developmental origins of creativity and the importance of statistical learning through early development.

Statistical learning is intimately linked to brain development. For example, statistical learning of language and music starts at an early age and is shown to play a significant role in acquiring the delta-band rhythm that is essential for language and music learning. However, it remains unclear how auditory cultural differences affect the statistical learning process and the resulting probabilistic and acoustic knowledge acquired through it. This study examined how children's songs are acquired through statistical learning. This study used a Hierarchical Bayesian Statistical Learning (HBSL) model, mimicking the statistical learning processes of the brain. Using this model, we conducted a simulation experiment to visualize the temporal dynamics of perception and production processes through statistical learning among different cultures. The model learns the children's songs (MIDI files) including English, German, Spanish, Japanese, and Korean songs as the training data. This study investigated how the model transforms the internal model over 15 trials of learning in each song. Furthermore, using the probability distribution of each model over 15 trials of learning each song, new songs were probabilistically generated. The results suggest that, in learning processes, chunking and hierarchical knowledge increased gradually through 15 rounds of statistical learning for each piece of children's songs. In production processes, statistical learning leads to the gradual increase of delta-band rhythm (1-3 Hz). Furthermore, by combining the acquired chunks and hierarchy through statistical learning, new music can be generated gradually in comparison to the original songs (i.e., the training songs). These findings were observed consistently, irrespective of culture. The present study indicates that the innate statistical learning capacity of the brain, irrespective of cultural background, contributes to the acquisition and generation of delta-band rhythm, which is critical for acquiring language and music. It is suggested that cultural differences may not significantly modulate the statistical learning effects since statistical learning and slower rhythm processing is both essential functions in the human brain across cultures. Furthermore, statistical learning of children's songs leads to the acquisition of hierarchical knowledge and the ability to generate novel music. This study provides a novel perspective on the developmental origins of creativity and the importance of statistical learning through early development.
