“…Even at 7.5 months of age, infants can dissociate both pure tones and phonemes only when these are at least approximately 75 ms apart (Benasich & Tallal, 2002; Partanen et al, 2013). In the visual domain, this processing slowness has even more drastic effects: 5-month-olds require an interval of more than a second to perceive two stimuli as independent (Hochmann & Kouider, 2022; Tsurumi et al, 2021). These modality-dependent effects may be an additional challenge for the acquisition of native phonemes, for which infants also rely on visual cues (e.g., mouth movements; Altvater-Mackensen et al, 2016; Burnham & Dodd, 2004; Ter Schure et al, 2016).…”

Infants master temporal patterns of their native language at a developmental trajectory from slow to fast: Shortly after birth, they recognize the slow acoustic modulations specific to their native language before tuning into faster language-specific patterns between 6 and 12 months of age. We propose here that this trajectory is constrained by neuronal maturation—in particular, the gradual emergence of high-frequency neural oscillations in the infant electroencephalogram. Infants’ initial focus on slow prosodic modulations is consistent with the prenatal availability of slow electrophysiological activity (i.e., theta- and delta-band oscillations). Our proposal is consistent with the temporal patterns of infant-directed speech, which initially amplifies slow modulations, approaching the faster modulation range of adult-directed speech only as infants’ language has advanced sufficiently. Moreover, our proposal agrees with evidence from premature infants showing maturational age is a stronger predictor of language development than ex utero exposure to speech, indicating that premature infants cannot exploit their earlier availability of speech because of electrophysiological constraints. In sum, we provide a new perspective on language acquisition emphasizing neuronal development as a critical driving force of infants’ language development.

“…The stimuli were four colored Japanese female faces taken as frontal views showing a neutral expression (Figure 1a). These four female faces were identical to those used in our previous study (Tsurumi et al., 2021). All stimuli were cropped into an oval shape (5.1° in width and 7.4° in height) to remove the outer features, such as the neck, shoulders, and hair.…”

The spatial location of the face and body seen in daily life influences human perception and recognition. This contextual effect of spatial locations suggests that daily experience affects how humans visually process the face and body. However, it remains unclear whether this effect is caused by experience, or innate neural pathways. To address this issue, we examined the development of visual field asymmetry for face processing, in which faces in the upper visual field were processed preferentially compared to the lower visual field. We found that a developmental change occurred between 6 and 7 months. Older infants aged 7–8 months showed bias toward faces in the upper visual field, similar to adults, but younger infants of 5–6 months showed no such visual field bias. Furthermore, older infants preferentially memorized faces in the upper visual field, rather than in the lower visual field. These results suggest that visual field asymmetry is acquired through development, and might be caused by the learning of spatial location in daily experience.

“…This means that a faster iAPF will make it easier to segregate information occuring in quick temporal succession, indicating that the acceleration in iAPF across infancy and childhood will allow children to dissociate information at smaller temporal intervals as they mature. In line with this, infants initially have very long temporal integration windows (Hochmann & Kouider, 2022;Tsurumi et al, 2021): While adults can differentiate tones if they are separated by at least 20 ms (Giraud, 2020;Joliot et al, 1994), 7.5-month-old infants need a total of ~150 ms difference in tone onsets in order to process two tones as separate (Benasich & Tallal, 2002). The iAPF might thus reflect processing constraints that change with development, determining the limits of neural temporal processing.…”

Maturational constraints on tracking of temporal attention in infant language acquisition.

Children are active learners: they selectively attend to important information. Rhythmic neural tracking of speech is central to active language learning. This chapter evaluates recent research showing that neural oscillations in the infant brain synchronise with the rhythm of speech, tracking it at different frequencies. This process predicts word segmentation and later language abilities. We argue that rhythmic neural speech tracking reflects infants’ attention to specific parts of the speech signal (e.g., stressed syllables), and simultaneously acts as a core mechanism for maximising temporal attention onto those parts. Rhythmic neural tracking of speech puts a constraint on neural processing, which maximises the uptake of relevant information from the noisy multimodal environment. We hypothesise this to be influenced by neural maturation. We end by evaluating the implications of this proposal for language acquisition research, and discuss how differences in neural maturation relate to variance in language development in autism.
