  • Reward-related language processing of maternal speech in infants at different likelihood of ASD

    Eiichi Hoshino, Masahiro Hata, Mingdi Xu, Yasuyo Minagawa

    Social Cognitive And Affective Neuroscience (Oxford University Press (OUP))  21 ( 1 )  2025.12

    Abstract

    This longitudinal study investigated the differential impacts of maternal speech on early socio-communicative development in infants at low likelihood (LL) and elevated likelihood (EL) of Autism Spectrum Disorder (ASD). Using functional near-infrared spectroscopy, we measured cortical responses and connectivity in 6-month-old infants while they listened to their mother’s voice and an unfamiliar female voice. LL infants exhibited extensive cortical activation and robust connectivity in temporal and frontal regions, particularly in areas associated with voice processing, reward, and language functions. In contrast, EL infants showed minimal activation and weaker connectivity in these regions. Specifically, LL infants demonstrated significant connectivity between the superior temporal gyrus and the inferior frontal gyrus on the left side, and between the orbitofrontal cortex and language areas, facilitating language processing and reward-related responses to maternal speech. These neural patterns were absent in EL infants, highlighting a neural basis for subsequent language delays. Furthermore, many of these reward-related or language-related networks predicted subsequent language development. Our findings underscore the importance of neural sensitivity to familiar human voices, regarding them as rewards that will eventually facilitate the acquisition of speech.

  • Emerging sensitivity to talking mouth in infants with low and elevated likelihood of autism spectrum disorder: A longitudinal study

    Infant Behavior and Development (Elsevier BV)  79   102057 - 102057 2025.06

    Last author, Accepted,  ISSN  01636383

    　View Summary

    The talker's mouth provides significant multimodal information that supports language development. Studies have revealed that infants over 6 months of age show increased attention to the mouth of a talking face, which results in vocabulary growth. However, few studies have reported the relationship between early gaze behavior and later language development in infants with an elevated likelihood of autism spectrum disorder (ASD) (EL infants). Since ASD cannot be diagnosed in infancy, these infants provide a valuable opportunity to investigate early developmental differences in visual attention that may be associated with ASD. Therefore, we conducted a longitudinal eye-tracking experiment at ages 6, 9, 12, 18, and 24 months to investigate differences in gaze behavior between infants with a low likelihood of ASD (LL infants) and EL infants. We found that, exclusively in LL infants, the proportion of mouth-looking time significantly increased from 6 months to 9 months of age and remained relatively constant thereafter. In contrast, in EL infants, although the proportion of mouth-looking time gradually increased with age up to 24 months, their attentional change to talking mouth started later than that in LL infants. Furthermore, our results showed a conditionally positive relationship between mouth-looking and expressive vocabulary size in LL infants but not in EL infants. These findings indicate that EL infants may not utilize audiovisual information as valuable cues for language acquisition during infancy and toddlerhood, which may be a factor in their slow language development.

  • Classification of power grip and precision grip in children using an EIT-based tactile sensor

    　View Summary

    Quantitative monitoring and measurement of hand motion in children are crucial to support healthy development. Electrical impedance tomography-based tactile sensors, also known as tomographic tactile sensors, provide a promising approach for grasp classification. Our previous study in adults and children demonstrated the feasibility of pinch classification using a cylindrical device equipped with the tomographic tactile sensor. In this study, we developed a new sensing device to classify the power grip and precision grip in children. In order to address concerns that children might lick or swing the device, a cylindrical sensing device was integrated sensor and measurement circuit, incorporated a protective layer for enhanced safety. Seventeen children participated in an experiment to evaluate the feasibility of the grasp classification. The classification features were voltage vectors and reconstructed images obtained from the sensor, and two machine learning methods were used as the classifiers. The average classification accuracy exceeded 85% for both feature types, surpassing the chance level of 50%. These results demonstrate that the basic grasp patterns in children can be accurately classified using a tomographic tactile sensor. This study provides new insights into the future application of grasp motion classification in children.

  • A Two-Way Analysis of Brain Synchrony: Assessing Brain-Event Relationships Using Information Metrics

    Satoshi Morimoto, Yasuyo Minagawa

    IEEE Journal of Selected Topics in Quantum Electronics (Institute of Electrical and Electronics Engineers (IEEE))  31 ( 4 ) 1 - 12 2025

    Last author, Accepted,  ISSN  1077260X

    　View Summary

    Functional near-infrared spectroscopy (fNIRS) is well-suited for hyperscanning in naturalistic situations, offering significant potential for assessing social brain function in everyday life. Previous studies have reported inter-brain synchrony during social interactions and sought to explore its mechanisms by correlating behavioral events with brain signals. However, commonly used regression analyses, such as Generalized Linear Models (GLM), rely on target events hypothesized as explanatory variables. This reliance introduces a dependency on the researcher's assumptions, which can compromise replicability in social neuroscience. While such dependency may be less problematic in strictly controlled experimental paradigms focused on specific hypotheses, it poses significant challenges in naturalistic experiments like social interactions, where numerous events and signals may serve as potential explanatory variables. To address this limitation, we introduced a new approach: signed-normalized mutual information for wavelet transform coherence (WTC-sNMI). This method enables a two-way analysis to evaluate relationships between event sequences and brain synchrony. Through simulations and real-data applications, we evaluated the performance of the proposed method. The results showed that WTC-sNMI analysis performed comparably to regression analysis in detecting both inter-brain synchrony and within-brain synchrony (i.e., brain connectivity). Moreover, applying WTC-sNMI to a tapping dataset revealed the expected patterns of synchrony between the lateral sides of the motor area. These findings validate the effectiveness of WTC-sNMI as a robust two-way analytical tool for studying brain-event relationships.
