Diversity of key consonants used in communication (DKCC) is a value-added predictor of expressive language growth in initially preverbal children with autism spectrum disorder (ASD). Studying the predictors of DKCC growth in young children with ASD might inform treatment of this under-studied aspect of prelinguistic development. Eighty-seven initially preverbal preschoolers with ASD and their parents were observed at five measurement periods. In this longitudinal correlational investigation, we found that child intentional communication acts and parent linguistic responses to child leads predicted DKCC growth, after controlling for two other predictors and two background variables. As predicted, receptive vocabulary mediated the association between the value-added predictors and endpoint DKCC.

Humans establish and maintain complex cooperative interactions with unrelated individuals by exploiting various cognitive mechanisms, for instance empathic reactions and a preference for prosocial actions and individuals over antisocial ones. The key role played by these features across human sociomoral systems suggests that core processes underpinning them may be evolved adaptations. Initial evidence consistent with this view came from studies on preverbal infants, which found a preference for prosocial over antisocial individuals.

Cataract in childhood can be associated with a high amblyogenic risk depending on the age at onset, extent of lens opacity and cataract laterality and accompanying ocular diseases. Early diagnosis and initiation of adequate treatment of a cataract in childhood are essential for a favorable long-term development of visual acuity. The decision for or against surgical treatment is essentially dependent on the estimation of the individual amblyogenic risk.

Purpose: The Language ENvironment Analysis (LENA) is a technological tool designed for comprehensive recordings and automated analysis of young children's daily language and auditory environments. LENA recordings play a crucial role in both clinical interventions and research, offering insights into the amount of spoken language children are exposed to in their homes, including adult word count (AWC) and child vocalization count (CVC). Although LENA was initially developed for American English, it has been validated in various other languages.

While pre-verbal infants may be sensitive to others' mental states, they are not able to accurately answer questions about them until several years later, an ability referred to as having a theory of mind. Here we ask whether infant social-cognitive sensitivity is subserved by the same brain mechanisms as those that support theory of mind in childhood. To do so, we explored the relationship between functional sensitivity of the right temporal-parietal junction to mental state processing in infancy, a region known to underlie theory of mind in older children, and explicit theory of mind reasoning in the same group several years later.

Background: Very early bilateral cochlear implant (CI) provision is today's established standard for children. Therefore, the assessment of preverbal and verbal performance in very early stages of development is becoming increasingly important. Performance data from cohorts of children were evaluated and presented based on diagnostic assessment using chronological age (CA) and hearing age (HA).
