Assessing the effect of object locations on word learning during naturalistic adult–child interactions
The aim of this study was to assess previously observed relationships between object locations and early word learning within an ecologically valid design. Adults labeled objects during openly structured interactions with their child. Fine-grained distributions of object locations were determined by a convolutional neural network. However, an analysis of the distributions of these locations during the interactions revealed that none of the spatia…
Household stress moderates the association between caregiver metacognition and infant sustained attention
Previous work has shown that caregiver executive functions (EFs) are robustly linked to EFs in children. However, existing evidence has used mixed methods approaches combining questionnaires and experimental tasks in older children. The current study used contextually similar questionnaires to examine whether caregiver EFs were linked to infant EFs, and whether household stress and socioeconomic status moderated these associations. Ninety‐one fam…
Brain‐Behavior Associations During Interactions Between Caregivers and Infants
Previous research has shown that infants' abilities to sustain attention are influenced by caregivers' attentional behaviors. Here, we inquired whether brain function in infants was linked to brain function in caregivers during attention periods in dyadic interactions, and whether this brain function was associated with visual short‐term memory in infants. Caregivers ( n = 90, mean age = 33.5 years) and infants ( n = 91, mean age = 251.3 days) we…
Stunting in infancy is associated with atypical activation of working memory and attention networks
Stunting is associated with poor long-term cognitive, academic and economic outcomes, yet the mechanisms through which stunting impacts cognition in early development remain unknown. In a first-ever neuroimaging study conducted on infants from rural India, we demonstrate that stunting impacts a critical, early-developing cognitive system-visual working memory. Stunted infants showed poor visual working memory performance and were easily distracti…
