Infants at elevated likelihood for or later diagnosed with autism typically have smaller vocabularies than their peers, as shown by the Mullen Scales of Early Learning (MSEL) and the MacArthur-Bates Communicative Developmental Inventory (CDI). However, the extent to which MSEL and CDI scores align remains unclear, especially across clinical and non-clinical populations. This study examined whether the concurrent validity of the MSEL and CDI differs based on autism likelihood and diagnosis.

- Efficient classification of infants' body position is essential for monitoring motor development and detecting potential issues early, facilitating timely interventions for healthy growth.
- Manual classification via video is labor-intensive, prompting the use of Inertial Motion Unit (IMU) sensors for automated body position classification, utilizing data from infants aged 4-12 months during play activities.
- The study found that the CatBoost Classifier outperformed the Random Forest Classifier in identifying body positions, with high accuracy rates for Supine, Sitting, and Prone positions, while emphasizing the significance of accelerometer and magnetometer data in enhancing classification accuracy.
Humans pay special attention to faces and speech from birth, but the interplay of developmental processes leading to specialization is poorly understood. We investigated the effects of face orientation on audiovisual (AV) speech perception in two age groups of infants (younger: 5- to 6.5-month-olds; older: 9- to 10.

In adults cortical representations of visual speech are processed in the putative temporal visual speech area (TVSA), but it remains unknown how these representations develop. We measured infants' cortical responses to silent visual syllables and non-communicative mouth movements using functional Near-Infrared Spectroscopy.

Although there is evidence that the fronto-temporal network is active during perception of audiovisual speech in infancy, the development of fronto-temporal responses to audiovisual integration remains unknown. In the current study, 5-month-olds and 10-month-olds watched bimodal (audiovisual) and alternating unimodal (auditory + visual) syllables.
