Preferential looking to eyes versus mouth in early infancy: heritability and link to concurrent and later development

Charlotte Viktorsson et al.

Summary: This study suggests that infant's preference for looking at eyes versus mouth is influenced by genetic factors and is associated with their receptive vocabulary.

Protracted development of motor cortex constrains rich interpretations of infant cognition

Mark S. Blumberg et al.

Summary: Cognition in preverbal human infants is inferred from overt motor behaviors, such as gaze shifts, head turns, or reaching for objects. However, infant mammals, including human infants, show prolonged development of cortical motor outflow. The neonatal cortex in humans lacks the ability to generate motor behaviors that can support inferences about infants' cognitive abilities, challenging claims of developmental continuity between infant and adult cognition. Recognizing the protracted development of the motor cortex should lead to a more cautious interpretation of infant cognition and encourage further consideration of subcortical mechanisms in early cognitive development.

Social Attention: Developmental Foundations and Relevance for Autism Spectrum Disorder

Terje Falck-Ytter et al.

Summary: The term social attention (SA) has been increasingly used in cognitive neuroscience and developmental psychopathology literature to better understand the early development of autism spectrum disorder (ASD), but the theoretical discussions have not kept pace with its various applications. This study reviews key candidate SA phenotypes in early life and argues that most of them do not represent unique socioattentional processes but should be understood within the broader context of bottom-up and emerging top-down attention. Although some SA behaviors are linked to the early development of ASD, they may reflect differences in social motivation rather than attention itself. The widespread use of the term SA without proper definition is problematic and more conceptual clarity is needed to guide research questions and early intervention strategies.

Pupil size and pupillary light reflex in early infancy: heritability and link to genetic liability to schizophrenia

Ana Maria Portugal et al.

Summary: This study demonstrates that certain pupil measures are highly heritable in early infancy, with genetic factors influencing baseline pupil size and constriction in response to light showing substantial independence. Additionally, there is a significant positive association between infant tonic pupil size and common genetic variants linked to schizophrenia.

Mapping genomic loci implicates genes and synaptic biology in schizophrenia

Vassily Trubetskoy et al.

Summary: In this study, a two-stage genome-wide association study was conducted to identify common variants associated with schizophrenia. The results revealed 287 distinct genomic loci and 120 genes likely to be involved in the development of schizophrenia. This research provides valuable insights into the pathophysiology of schizophrenia and offers a resource for further mechanistic studies.

The Babytwins Study Sweden (BATSS): A Multi-Method Infant Twin Study of Genetic and Environmental Factors Influencing Infant Brain and Behavioral Development

Terje Falck-Ytter et al.

Summary: Twin studies are crucial in understanding the contributions of genes and environment to trait variation. The Babytwins Study Sweden (BATSS) is a multi-method longitudinal twin study that combines advanced technologies in developmental cognitive neuroscience and genomics, producing high-quality results.

Declining Gaze to Faces in Infants Developing Autism Spectrum Disorder: Evidence From Two Independent Cohorts

Devon N. Gangi et al.

Summary: The study found that children with ASD showed a sharp decline in gaze to faces between 6 and 36 months of age, while children without ASD remained stable. This suggests that trajectory-based screening methods might be more effective in identifying early signs of developmental abnormalities for early intervention.
