Comparisons were made on the rated behaviors between children classified as either encephalopathic or nonencephalopathic. Analyses were conducted separately for infants (...

This study investigated the relationships between pre- and early post-natal maternal depression and their changes with frontal electroencephalogram (EEG) activity and functional connectivity in 6- and 18-month olds, as well as externalizing and internalizing behaviors in 24-month olds (n = 258). Neither prenatal nor postnatal maternal depressive symptoms independently predicted neither the fron...

Distraction has been shown to be an effective technique for managing pain in children; however, few investigations have examined the utility of this technique with infants. The goal of the current study was to investigate the effectiveness of movie distraction in reducing infants' immunization distress.

Interoception—the ability to perceive and respond internal bodily sensations—is fundamental for the continuous regulation of physiological processes. Recently, it has been suggested that because infants depend completely on their caregivers survival, development interoceptive processing emerges as a result early dyadic interactions, relies caregivers’ meet infants’ needs.

This study examined whether 16-month-old walking infants take the material composition of a handrail into account when assessing its effectiveness as a tool to augment balance. Infants were encouraged to cross from one platform to another via bridges of various widths (10, 20, 40 cm) with either a "wobbly" (foam or latex) or a wooden handrail available for assistance. Infants attempted to walk ...

We extract the book reviews on picture books written on the Web site specialized in picture books, and found that those reviews reflect infants’ behavioral expressions as well as their parents’ reading activities in detail.
